There are three techniques to measure pressure: gauge, absolute, and vacuum. A pressure gauge measures fluid intensity. For the configuration and fine-tuning of fluid power devices, as well as for troubleshooting, pressure gauges are essential. Fluid power systems would only work as expected or reliably with pressure gauges. With the aid of gauges, one can ensure that no leaks or pressure variations can impact the hydraulic system's ability to function.

How is a Pressure gauge used?

It may surprise you that pressure gauge technologies are still changing, given that fluid power systems have employed pressure gauges for over a century. Some of its utility includes-

·         Diverse industries employ differential pressure gauges to keep track of purification, hydraulic gradient, and liquid flow. They are crucial in various settings, including distilleries, petrochemical and chemical companies, power plants, and clean rooms.

·         The stainless steel Panel mounted pressure gauge has sections that resist corrosion and a threaded interface that thread into the tank, pipe, or process. The back plate or circle mounts to the panel. Their back flange fixes it to the surface and also goes by the name of surface-mount gauges.

·         Meteorologists use absolute pressure gauges to track adiabatic saturation pressure and perform distillation processes in the oil refining sector. A pressure gauge helps check for leaks in tanks and circuits, monitors the drop in pressure of extraction vacuum columns, and measures the vapor pressure of liquids. Absolute pressure gauges are used in food packing as well as vacuum pumps. Barometers are used to measure atmospheric pressure.

·         The most popular pressure measurement tools in industrial settings are gauge pressure measuring devices, which are particularly common in the electrical, petrochemical, pharmaceutical, chemical, medical, agricultural, freezer, air-conditioning, and cleanliness industries.

·         A Sanitary pressure gauge is a tool for pharmaceutical, food processing, and sanitary industries. These pressure gauges for the sanitary industry guarantee the highest level of hygiene due to their lack of interstices and mirror-finished components. The interior volumes and temperature error can be decreased thanks to the pressure sensor and diaphragm seal combination. The instruments are helpfully filled to lessen the effects of harsh working circumstances like vibrations and pulsations.

·         A Contractor pressure gauge is helpful for plumbing, heating, ventilation, and air conditioning applications.

A pressure gauge helps measure the pressure of all the matter in every form, and it also has the power to do away with leakage. Whether used to test machinery or run it, the correct pressure gauge helps minimize expensive downtime.

It operates by converting the energy of electric motors into kinetic energy

Centrifugal pumps: It operates by converting the energy of electric motors into kinetic energy. These types of pumps are used frequently in hydraulic systems. These are the efficient industrial pumps that are frequently used in most of the industries. Air driven pumps: As the name implies, these types of pumps use the compressed air to operate the pumping operation. There are different types of industrial pumps that vary in the mode of operation. It also uses rotor and diaphragm for the effective movement of the fluid. Fluid enter the inlet of the pump and then passes to the impeller which rotates producing the centrifugal acceleration and when the fluid leaves the impeller a low pressure area is created, which is required to allow more fluid to enter the inlet.

Some efficient industrial pumps are listed below: Positive Displacement Pumps: It has an expanding cavity on the inlet side and a decreasing cavity on the discharge side. The impeller is the rotating part that is responsible for the conversion of electric motor energy into kinetic energy. Compressed air helps to maintain a constant flow of the fluid without any barrier. These pumps are known as constant flow machines, because they are capable of providing constant flow of fluid without any decline in the intensity of the flow. Besides, frequent maintenance is needed for better performance. Connecting the impellers in series will increase the pressure at the outlet, while parallel arrangement enhances the higher flow output.

The kinetic energy is then used to generate the pressure that is needed to pump the fluid.Pumps are used in most of the industries for various purposes. If there are two or more impellers then they are known as multistage centrifugal pumps. Some basic types of positive replacement displacement pumps are reciprocating, metering and rotary pumps. These types of pumps are used in large numbers worldwide, Mating Rings Manufacturers due to its efficiency and longer lifespan. To resolve the leakage problems, presently mechanical seals are used due to its efficiency in completely fixing the leakage problem, but this process is quite expensive, while on other hand we can use packing that is less expensive but may not last longer.

Air driven pumps are used to pump most of the fluid types and are used mainly in flammable gas pumping, because this pump doesn’t require electricity for its working therefore during gas pumping there are very less possibility for damages. However, small problems such as leakage may considerably reduce the performance of the pumping system.. Pumps that are used in industries must have better efficiency to perform the works in a faster way. It operates by forcing a fixed volume of fluid that from the suction pressure section of the pump into the discharge zone of the pump

“And that, ladies and gentleman, is a wrap!”

A sigh that somehow managed to bridge the gap between despair and disbelief filtered over the comm channel, “Don’t go Hollywood on me now, Thunderbird Four. Are the targets clear of the danger zone?”

“Yes siree,” came the rather chipper reply, “Hazardous material has been removed and ultrasonic sweeps show no more underwater casualties. Danger zone is officially cleared. Standby for pickup, Thunderbird Two.”

“F.A.B,” came the rich tones of brother Numero Dos, “Can you be Pacific about your location, please?”

“Careful, Virg. I have a license to krill, you know,” Gordon warned playfully, aligning the little yellow sub so that she was within grabbing distance of module four’s cable.

A snort was offered by Virgil in lieu of a verbal reply, “I never knew it was possible to stick one’s head so far up one’s ass. Tell me, what did you have for dinner last night?”

“Same thing as you, bro,” Gordon countered, watching happily as his newly relinquished charges swam off to freedom. An emergency call had come in from a concerned student at the University of Otago claiming that several members of the dolphin pod she was satellite tracking in Kaikoura had run afoul of a discarded fishing net. Ever eager to help an animal in distress and with the right gear at his disposal, Gordon had roused Virgil and politely requested that the engineer taxi him the two and a half thousand miles to New Zealand’s South Island.

A decent number of locals had joined the rescue effort by the time Thunderbird Two arrived on scene, and it was with unbridled joy that they cheered as the last dolphin was cut free by Four’s robotic arms. Aside from managing to dodge an animal welfare bullet, the cetaceans were a tourism magnet and thus, an invaluable source of income for the town.

“Kia ora! Thank you!” a young woman called, scurrying up to shake Gordon and Virgil’s hands, “I’m Mandy Harrell, and on behalf of the IMMA, I just want to say how grateful we are to International Rescue for your help here today.”

Gordon smiled warmly, “I’ve always admired the work of the Marine Mammal Protected Areas Task Force. The pleasure is all mine.”

“Having two representatives from the world’s most elite rescue organisation here will do wonders for our public image,” Mandy enthused, shaking her head in excited disbelief, “We’re trying to raise enough funds to conduct a clean-up operation along this section of coastline. We suspect the net you just removed is one of several left by a group of unregulated fishermen we apprehended last June. Our goal is to have the first five hundred meters of coast cleared by the time the humpbacks arrive next month, but at the rate things are going, we’ll be several thousand dollars shy of our target.”

A soft series of beeps sounded as Gordon’s comm picked up an incoming call, but he ignored it in favour of giving Mandy his undivided attention. It was probably just John checking in. Or Scott forewarning him that Grandma was cooking and that they were out of laxatives.

“Perhaps we could donate the remainder?” Gordon offered, “I’d be delighted to help you guys in any way that I can.”

Virgil felt apprehension crawl up his spine when Mandy smiled, but didn’t instantly accept the (rather generous) offer that had been had laid down.

“That’s incredibly kind of you, but we like to be as self-sufficient as possible where money is concerned,” the young woman replied, tilting her head to take the sting out of her words, “If you’d be willing to donate your time however, that would be greatly appreciated.”

“Sign me up!” Gordon exclaimed, raising his hand in a similar manner to Scott’s scout oath, “I’m sure Alan can cover for me if I take an extra day off this week. You get that, John? Take me off the roster for tomorrow, please. Forward all emergencies necessitating the use of Thunderbird Four to Alan. I’ll take over his Monday shift next week as compensation.”

“Done and done,” came the smooth reply of the middle brother, “And now we wait for the inevitable tantrum.”

A chuckle bubbled up Virgil’s diaphragm as he adjusted his sash and fixed Mandy with an inquisitive gaze, “So, what will you have him doing? Shovelling seaweed? Litter picking? Seagull whispering?”

Mandy let loose a laugh that sounded a fraction forced, “Not quite. We’re a new partner of Otago University and recently signed a collaboration agreement with their School of Arts for the upcoming semester. We were going to host a series of life drawing sessions out on the open water, but the university probably won’t commit after the publicity this incident will undoubtedly be on the receiving end of. Do either of you have any experience with modelling by any chance?”

Virgil had less than a second to intervene before Gordon started uncontrollably word vomiting.

“Oh yes!” the aquanaut swanked, preening like a peacock, “Vogue, Armani, Cosmo, Grazia, Gucci, Vanity Fair, Louis Vuitton, Dior, Prada, Salvatore Ferragamo, Fendi, Saint Laurent, Givenchy, Balmain, Alexander McQueen, Burberry, Calvin Klein, Ralph Lauren, and KFC have all had a piece of this perfectly symmetrical face over the years.”

The squeal that tore out of Mandy had Virgil wondering if she was as smart as her paper qualifications claimed. A discreet search of IMMA on his comm gauntlet had revealed a string of abbreviations after her name that rivalled the Cambodian alphabet, yet she seemed perfectly willing to believe that Gordon really had modelled for all of the companies he’d just listed.

In truth, the closest the fourth Tracy had come to modelling was when his swim trunks had ripped during a family trip to the Seychelles. The scathing email that Scott had penned to the CEO of Speedo had been accompanied by multiple pictures of said trunks (both on and off their owner), along with the threat of legal action should Gordon end up deported for ‘indecent exposure’.

“Perfect!” Mandy effused, her green eyes glowing with excitement, “Ticket sales will skyrocket with a member of International Rescue as the subject! I must ring Shona and tell her to re-book the town hall.”

Valuable blood drained from Gordon’s face as the reality of what he’d inadvertently signed up for dawned on him like a sunrise in hell, “Uh, I thought you just wanted me as a poster boy for your open water sessions? Y’know…posing with porpoises, photobombing seals…helping to smooth over the bad publicity, right? Getting people to focus on the good rather than the bad?”

Mandy shook her head, her brown curls bucking in the breeze that was buffeting the shore, “It’ll be all over the news that it was you guys who saved the day, not us. International Rescue’s presence here is the catalyst for a financial surge we can’t afford to miss. I’m begging you. The dolphins are begging you. Please, help us to help them.”

Gordon chewed his lip. While he was probably the brother least phased at the prospect of getting his kit off for charity, he knew that Scott would be on him like shit on velcro if his derriere ended up plastered across the front of every global news channel in all its bare glory.

“Thunderbird Two, a priority call just came in from a couple of wreck divers in Chuuk Lagoon, Micronesia,” John’s voice, ever calm and authoritative, served as both a welcome distraction and an excuse to leave, “Alan and Kayo just got called away to a flood in Columbia and Scott is on a conference call with Colonel Casey, which makes you two our closest and only available option.”

“Please say you’ll come?” Mandy wheedled, panic slipping into her voice when Virgil and Gordon began to walk towards Two’s cockpit platform, “It’ll just be for a few of hours, and there’ll be a free lunch.”

That got Gordon’s attention. He’d been prepared to agree for the sake of the dolphins and inbound humpbacks, but the promise of free food sealed the deal.

“Ten o’clock tomorrow!” the aquanaut yelled, waving as the platform began to ascend, “I’ll need a toasted cheese on granary and five of whatever your equivalent of Celery Crunch bars are!”

“Uh, Gordon?” Virgil’s voice was low and gentle, a stark contrast to the shrieks of delight Mandy was emitting, “Do I need to remind you about what happened last time you signed up for something like this?”

Any confidence the aquanaut had vanished quicker than a burp in a dust storm as a memory he’d worked hard to suppress began to surface.

TBC.

An intro to Different Types involving Hydrogen Compressors

hydrogen compressor

An intro to Different Types involving Hydrogen Compressors A hydrogen compressor, for the reason that name recommends, is a sort of product that compresses hydrogen as well as turns it straight into liquefied or compressed hydrogen. These types of devices reduce the volume level of hydrogen to obtain the desired results.

hydrogen compressor

Sends vs Compressors

There is actually not a terrific difference among a fridge and the pump. Both of typically the devices can increase often the stress on a chemical to transport this by way of a pipe. Since that can be done to compress gas, you need to use this compressor in order to reduce the actual hydrogen fuel volume. However, a standard pump increases the strain to transferred liquid hydrogen to another place.

Varieties

Provided below are a several types of Hydrogen Compressors.

Reciprocating Piston Units

The unit are one of the particular most common units to be able to compress hydrogen. Typically, they might be found in refineries exactly where these are the backbone of unsavory olive oil refinement. Usually, all these devices can be non-lubricated for oil-lubricated. For greatest results, found advanced expertise of packing jewelry and also piston sealing.

Ionic Liquefied Piston Units

For the reason that brand suggests, these compressors are generally based on ionic fluid appui rather than any metal piston. Alternatively, intervention metal diaphragm compressors utilize a different technology.

Electrochemical Units

This type connected with compressor employs several écorce electrode assemblies just similar to the one found throughout proton-exchange membrane fuel tissue. The advantage of these units will be that they element zero moving parts. Furthermore, that they are quite compact. Concerning as functionality is troubled, a electromechanical compressor is usually not greater than some sort of fuel cell. Any time latest is passed through typically the membrane, hydrogen passes delete word.

In these units, often the force requirement is multitude of cafes or 14500 PSI. This year and the years to come, a single-stage compression setting approximately 800 bars ended up being noted.

Hydride Units

Within the case of a new hydride compressor, they make use of tension and thermal components on the substance in purchase to absorb hydrogen gasoline at room temperatures. Later, high-pressure hydrogen is definitely published at high temperatures available as gas. Typically, an electrical power coils and hot normal water is used for you to temperature up the bed associated with hydride.

Piston-Metal Diaphragm Devices

These kinds of units are stationery and contains high pressure. That they are water-cooled and still have a number of stages. Since compressing fumes generates a lot regarding warmth, it is significant to know that the actual heat of the folded gas is actually reduced in between different periods in buy to make the contrainte far more isothermal. By predetermined, the effectiveness ratio will be 70% as soon as the process is usually complete.

Advised Rotor Sections

This refrigerator is structured on an involutes trochoid geometry that makes employ of the parallel trochoid curve so as to define the particular fundamental compression quantity. While far as the adiabatic performance is concerned, typically the process can give anyone can be a figure of 85 to help 85%.

Linear Models

Thready compressors make work with of dynamic counterbalancing. Inside these units, an additional mass is connected in order to any movable piston construction plus a compressor. The splendor of these compressors is definitely that they have actually zero intervalle while operating. And also, imply use a good deal of power.

Extended account short, this was an intro to different types involving hydrogen compressors. This can help you opt intended for the very best unit to be able to meet your needs.

The Best Humidifier for 2019

Why you should trust us

John Holecek is a former NOAA researcher and has studied atmospheric physics and chemistry in places from the continental US to the Arctic to the remote island nation of the Maldives. He is a longtime Wirecutter collaborator. For this guide, he weather-sealed his home office and installed an air conditioner to maintain stable initial conditions. He evaluated the humidifiers with two portable temperature and humidity data loggers, and used a laboratory-grade particle counter to size up the air washers (read more in How we tested).

Tim Heffernan is a Wirecutter writer and editor, and has conducted extensive real-world testing of air and water purifiers for our guides. For this guide, he tested nine humidifiers in his New York City apartment during the winter heating season, using the same data loggers.

Who this is for

If you are bothered by any of the symptoms caused by dry air, such as dry sinuses, nosebleeds, cracked and sore lips, or shocks from static electricity, the air in your home is likely too dry. In most of the US, this is primarily a winter problem, especially in homes with forced-air heating systems, which can drive indoor humidity as low as 10 percent, making it literally desertlike. However, dry air can also be an issue even if you have steam or under-floor heating, because cold winter air generally has less moisture than warm summer air.

Using a portable humidifier, such as the ones we researched here, is the cheapest and easiest way to humidify your home without needing to deal with an HVAC contractor. If you get one, you should keep the relative humidity levels in your home somewhere between 30 and 60 percent, which will alleviate the symptoms listed above while discouraging mold and mildew growth in your home. If you want to test your air before buying a humidifier, you can get a hygrometer on Amazon for about $10.

However, humidifying your home involves more than just buying a machine and keeping it filled with water. If you don’t take care to maintain your humidifier properly (see Health risks of a dirty humidifier), it can do more harm than good. Most humidifiers require regular maintenance, including a thorough cleaning at least once a week. There are exceptions, like our upgrade pick. But be honest with yourself: Are you ready to be a “humidifier parent”? If you know you’re not up for regular cleaning and maintenance, you may end up with a breeding ground for germs.

How we picked

This is the fifth iteration of this guide, so we went into it with considerable knowledge of what makes for a good humidifier, in terms of technology and design.

The truth is, most of the 21 machines we have tested over the years have performed adequately—but we’ve found huge differences in ergonomics, ease of cleaning and filling, quality of construction, and user interface. Because you generally have to interact with a humidifier daily—to refill the tank, sometimes more than once, and then restart and reset it—these factors always weigh heavily in our choice of which machines to pick for testing.

So do owner reviews and other testers’ findings. So as always, this time around we researched popular models on Amazon (paying attention to both positive and negative reviews), consulted AllergyBuyersClub.com, Top Ten Reviews, ConsumerSearch, and Best Buy, and read the comments from our previous guide for feedback and suggestions from our readers.

We focused on portable humidifiers because you can easily add one to any home or apartment and move it around as needed. We restricted our search to models rated to cover between 200 and 700 square feet: The low end of that scale is more than enough coverage for an average bedroom (which is primarily where these machines see use), and the high end is plenty for even the largest open spaces in most homes. Though you can find large console units theoretically capable of humidifying an entire home, the humidity levels will vary considerably with distance from the machine and room to room (even with all the doors open, which isn’t always practical), so we believe having a few, smaller humidifiers is the better option.

We largely limited our search to the two most common types of portable humidifier. They both employ simple, proven, effective mechanisms, and are extremely energy efficient.

Ultrasonic humidifiers use a rapidly vibrating diaphragm to launch microscopic droplets of water into the air, where they quickly evaporate and become water vapor—the source of humidity. These machines are generally very quiet (though they do emit an audible, mechanical hum), and cleaning them is simple, typically a matter of rinsing the tank and wiping down the internals every few days or weekly.

However, because they throw liquid water (not gaseous water vapor) into the air, minerals in the water can settle on surrounding surfaces as a fine white dust as the mist evaporates. Also, ultrasonic humidifiers must stand on top of a dresser, table, or shelf: The droplets need a bit of time to evaporate as they fall downward, or they will puddle on the floor.

Ultrasonic models can also overhumidify the air in a room, to the point that moisture condenses on floors, rugs, and furniture near the machine. And in the long term, overhumidification can promote the growth of mold and mildew in homes. For these reasons, we heavily favored ultrasonic models with built-in humidistats, which shut the machine off when the air reaches the desired humidity.

Lastly, if there’s no water in the tank to absorb the vibrations of the diaphragm, ultrasonic humidifiers can actually break themselves—so we looked only at models that had an auto-off when the tank ran dry.

Evaporative humidifiers use the natural process of evaporation to add moisture to the air. A fan draws air through a wet wick or filter, humidifying it before blowing it back out into the room. This technique has the big advantage of automatically preventing overhumidification: The evaporative process slows as the air gets wetter. That means evaporative humidifiers won’t produce condensation on floors and other surfaces and are unlikely to create conditions that promote mold and mildew.

On top of that, the evaporative process means any minerals in the water supply stay behind on the wick—so there’s no issue of white dust. Mechanically, evaporative humidifiers are robust and virtually failproof: They’re essentially room fans—and they emit the same, soft “white noise” that many people find soothing. Finally, they can operate without causing themselves any damage even if the tank runs dry.

Maintenance of evaporative models, however, is slightly fussier than for ultrasonic designs: The wicks need regular replacing (every one to three months) as they clog with minerals, and because the wet wicks can potentially be a breeding ground for mold and bacteria, you really need to do a thorough cleaning of the tank and internals at least once a week. We favored models that made these tasks easy and inexpensive.

We also considered two other types of humidifier. Warm-mist humidifiers work by heating water into steam. As you might guess, this approach is not terribly energy efficient, and the hot parts may present a burn risk. However, some people like the slight warmth that these models add to the air, so we tested a few popular models. Impeller humidifiers use a rapidly spinning disk to fling water against a diffuser plate that breaks the droplets into fine mist. They are quiet, but like the ultrasonic models they can produce a white dust. The moisture output is low, and the customer ratings we’ve seen on Amazon are so bad that we’ve skipped impeller humidifiers entirely in our testing.

After five iterations of this guide, we have placed 70 different humidifiers on our short list and tested 21. If you’d like to see our test plan in detail, it’s in a lower section called How we tested—that material normally appears at this point in a Wirecutter review, but it’s so extensive in this guide that we moved it after the discussion of our picks.

Our pick: Honeywell HCM-350

Our pick

The Honeywell HCM-350 Germ Free Cool Mist Humidifier has been our pick since 2015. It’s affordable, simple, durable, and highly effective—in a real-world test in a dry, steam-heated New York City apartment, it raised the humidity by almost 25 percent, turning in one of the very best performances we measured. But equally important, it’s also extremely easy to live with. It’s compact, and it can sit on the floor or on a table or shelf. It emits no bright light or loud beeps to keep you up at night. And it runs quietly, making only a soft “white noise,” like a room fan. Moreover, it’s the easiest humidifier to clean and fill we’ve ever found—the relevant parts are dishwasher-safe—which is invaluable, since those are the two tasks you’ll be doing most often with any humidifier. Rated for spaces as large as 400 square feet, it’s big enough to humidify almost any bedroom or living room. As of winter 2018, we’ve pitted it against 20 competitors, and at least eight Wirecutter editors have used one long-term in their own homes, and it’s still easily our consensus winner.

The Honeywell HCM-350 performs the most important task of a humidifier—raising the amount of moisture in the air—exceptionally well. In our real-world New York City apartment test, it raised the humidity by 23.5 percent, from an uncomfortably dry 26 percent to a pleasant 49.5 percent. That put it within an insignificant 1.5 points of the very best performer, and right at the EPA’s recommended “sweet spot” of 50 percent (beneficial for skin and respiratory-tract dryness, but below the level that encourages mold and mildew). Moreover, the Honeywell humidified the air quickly, outperforming all our other picks over the first two hours of the test. If you come home to a dry house or apartment, the Honeywell will make it comfortable soon. Encouragingly, these results also accord with the findings of our earlier tests under controlled conditions (see How we tested for details).

The Honeywell stands out for other, equally important reasons. Because it’s an evaporative humidifier, it emits gaseous water vapor, which means there is no risk of it creating puddles on your floor. Evaporation also leaves any minerals in the water behind, so you won’t see a layer of white dust around the machine. (Both of these concerns are a potential issue with ultrasonic humidifiers, including our pick for large spaces, the Levoit LV600HH, because those designs throw a mist of liquid water into the air instead of water vapor.) This means the Honeywell offers maximal options for placement: It can sit on the floor, behind a piece of furniture, or on a table or shelf. Ultrasonic models are more limited, as they have to reside on a table or shelf to allow enough time for the mist to evaporate before it falls onto a surface and makes a puddle. And because the evaporative process slows down the more humid the air gets, the HCM-350 is self-regulating: It can’t overhumidify a room the way ultrasonic models, which continuously pump water into the air, can.

Compared with our runner-up evaporative humidifier, the functionally similar SPT SU-9210, the Honeywell HCM-350 has a number of thoughtful design elements that make it much easier and more pleasant to use. Take the water tank: The Honeywell’s sits flat and stable on its top, allowing for hands-free filling (see the video below). The SPT’s tank rocks and wobbles, so you have to hold it while it fills. And look at the cap on the Honeywell’s tank—that “crossbar” allows you to get a really firm grip when opening or closing it. No other machine we tested has this feature; instead, they offer only ridges around the cap rim that get slippery when wet. (The other cap in our photo belongs to our ultrasonic pick, the Levoit LV600HH. The SPT SU-9210’s is much the same.)

The Honeywell’s controls could not be simpler: It has just a basic toggle like that of a room fan, with off/high/medium/low icons. You can easily adjust the settings even in the dark, which is handy if, as is common, you plan to use a humidifier in the bedroom. The SPT model has four separate buttons for setting fan speed, the humidistat, and the timer, and they’re not backlit, so they’re a bit tricky to use in the dark. They also beep loudly with every push—frustrating in a quiet bedroom or a baby’s nursery. The Honeywell’s toggle is silent. And the SPT’s blue LED display and red power light glow brightly—enough to hinder sleep—and cannot be turned off while the machine is plugged in (not just while it’s on). The Honeywell has a single, small, unobtrusive green bulb to let you know it’s running.

The HCM-350’s ease of cleaning is far better than that of many competitors, beginning with the fact that all the parts that touch water (and are thus liable to accumulate bacterial, algal, or fungal growth) contain no electronics and are completely submersible in water for easy washing. The fill hole of the tank is large enough for almost anyone to reach inside for scrubbing (that’s 6-foot-1 writer Tim Heffernan’s hand in the photo below). And both the tank and the water tray are dishwasher safe (top rack only, no detergent). This is how it should be. Yet the HCM-350 stands in stark contrast to many humidifier models we’ve looked at, which contain electronics in the base and require you to clean them by hand. (Its most similar competitor in our test, the SPT SU-9210, lets you clean the tray, but not the tank, in the dishwasher.)

Cleaning the Honeywell takes only a couple of minutes, thanks to smart design that makes every step easy.

Because evaporative humidifiers use a fan to blow air across the damp wick, they make a small amount of noise—but it’s a neutral, even calming, white noise that few people find objectionable. If you like the sound of a room fan, you’ll be happy with the Honeywell. (Wirecutter designer Orr Shtuhl, who lives in New York City, said, “One thing I personally like is that the two lower settings are very quiet, and the strongest setting is loud enough to be used for white noise—I like to block out street noise at night.”) We measured its sound level on high at 48.9 decibels from a distance of 1 meter; that’s well under the 55 decibels it takes to begin interfering with a typical conversation. The noise drops to a barely noticeable 40.3 decibels if you set the fan speed to medium. That’s comparable to the sound from many ultrasonic models, which are often billed as “silent”—but which do, in fact, produce a mechanical hum that noise-sensitive people may find less pleasant than the white noise of the Honeywell.

Finally, for several Wirecutter editors and writers who own the Honeywell, this model has proven extremely durable over the long term. Mechanically it’s very simple, meaning it has very little inside that can break. And the tank is blow-molded from a single, continuous piece of plastic (like a milk jug). The one-piece design is much less likely to develop leaks over time than the two-piece (or more) fused-plastic designs found on many other models, including two of our other picks, the SPT SU-9210 and Levoit LV600HH, because it doesn’t have any seams that can come apart. It will likely outlast its three-year warranty—which is already generous compared with most models’ one-year warranties—and none of our staffers have ever had a problem with it.

Including the purchase price, the cost of new filters, and the cost of electricity, the Honeywell HCM-350 will set you back about $250 over the course of its three-year expected service life (assuming you’re running it 24 hours a day, six months of the year—you may well run it far less). That’s on the low end of machines we’ve looked at.

Flaws but not dealbreakers

At 1 gallon, the HCM-350’s tank is on the small side; if you run it 24/7, you’ll refill it at least once. Larger tanks can support a full 24 hours of operation.

In a design quirk common to evaporative humidifiers, the bottom tray of the Honeywell doesn’t physically attach to the upper housing, where the fan and tank are located; the latter just rests on the former. If you need to move the unit, you have to reach all the way to the floor and get your fingers under the tray—otherwise you’ll leave it behind.

Replacement filters are a simple drop-in affair. And Honeywell-made filters (versus third-party filters) are impregnated with an antimicrobial finish that, the company claims, virtually eliminates mold and bacteria growth. Regardless, depending on the hardness of your water, Honeywell recommends replacing the filter every one to three months. It’s normal for the filter to turn brown or slimy as the mineral deposits build up, and you can extend the life of the filter by flipping it top to bottom every time you refill the tank or rinse out the base. But once the filter becomes saturated with minerals, the wicking ability is impeded, resulting in a drop-off in humidifying ability (and water consumption). So if you notice that there’s more water left in the tank than you expect when you go to refill it, it’s probably time to replace or clean the filter.

In January 2016 we investigated several complaints from readers about replacement filters for the Honeywell HCM-350. The complaints noted poor fit and stated that the replacements were thinner than the originals, looked different, or did not perform satisfactorily. We spoke at length with a representative of Kaz, the manufacturer of the HCM-350. In addition to answering our questions, the representative sent photographs and a physical sample of the current-issue replacement filter. We also independently ordered a replacement filter from Amazon to be sure we were getting the same model that our readers would. Here’s what we learned:

Kaz, the manufacturer of the Honeywell humidifier, switched from a 1½-inch-thick filter to a ¾-inch-thick filter around 2011. If anyone recently received a humidifier with a 1½-inch-thick filter, it was (very) old stock.

Kaz phased out the outer blue Airwash layer on the ¾-inch filters in 2014. The Airwash filter reduced the humidifiers’ output. Other than this change, the filters are identical.

The replacement filters that Kaz sent us, the replacement we got from Amazon, and the original that we pulled out of our test model were all identical. The replacements we got from Kaz and from Amazon both fit our HCM-350 humidifier perfectly.

Kaz sells the same replacement filter under two different names, the Honeywell Filter A and the Honeywell HAC-504 series; they are identical. (The latest version in the series, updated for increased efficiency, is the HAC-504V1.) Many third-party manufacturers also sell replacement filters that they describe as “HAC-504 compatible,” but Honeywell cannot vouch for these filters’ performance. Our link is to a genuine Honeywell HAC-504V1. Or, to be absolutely certain, you can order directly from the manufacturer.

Long-term test notes

Wirecutter’s Michael Zhao and Kevin Purdy have each used a Honeywell HCM-350 for several winters.

Michael, who lives in a radiator-heated New York City apartment and uses the Honeywell in the bedroom, said, “It’s so easy to clean that I actually clean it. Which is pretty great.” Cleaning is really important—and ease of cleaning is one of our main reasons for recommending the HCM-350. Michael added, “It’s annoying that the fan collects dust, but I’ve found that the protective screen comes off cleanly if you give it a good tug with needle-nose pliers.” That allows him to wipe the fan off (and reinstall the screen) without much fuss. After moving from an apartment with a standard 8-foot ceiling to one with 12-foot ceilings—a big jump in volume though not area, as both rooms are about 150 square feet—Michael noted an apparent drop-off in absolute humidification but also saw that the unit was still effective at reducing the symptoms of dry air, such as waking with a dry throat. Additionally, he owns a cat, and he has found that the wick collects pet hair; a weekly vacuuming (a two-minute job) clears that up.

Kevin and his wife live in a forced-air-heated Victorian house in Buffalo, New York; it gets very dry in the winter, and they also use their Honeywell HCM-350 in the bedroom. Kevin admits to being “an anti-hypochondriac” and “on the far left end of maintenance,” meaning he doesn’t clean his unit with any sense of urgency. He has generally given the Honeywell’s reservoir a scrub with dish soap once a week, and not cleaned the base plate or the filter with any regularity. He also has let water sit in the reservoir for days at a time. He adds: “I have not had anything bad happen to me.” Fine, but honestly, he should follow manufacturer guidelines for any humidifier, or else risk serious illness; in the case of the Honeywell, that maintenance includes a weekly scrub of the tank and tray and a rinsing of the wick. As for the HCM-350’s performance, Kevin said: “It works really well, and it doesn’t look terribly ugly in our bedroom. It hides in a corner and does the job.”

Runner-up: SPT SU-9210

Runner-up

If the Honeywell HCM-350 is out of stock, consider the SPT SU-9210 Digital Evaporative Humidifier, which also performed extremely well in our testing. As an evaporative humidifier, the SU-9210 has the same inherent benefits over ultrasonic models as the HCM-350: a lack of white dust and puddling, and a general inability to overhumidify. And it has a number of features that some people might appreciate and that the Honeywell lacks, including an accurate humidistat and a timer mode. But it’s not nearly as easy to clean as our top pick and has a number of maddening design flaws, which ultimately make it much more difficult to live with. We can recommend it only if the Honeywell is totally unavailable and you need a humidifier immediately.

As far as quantitative testing goes, the SPT model performed very well, scoring (like all our picks) at the top of our real-world tests in a dry, steam-heated New York apartment. When we tested the humidistat’s accuracy, it nailed the 55 percent target (see How we tested for complete test results). Its estimated operating cost of about $200 makes it about $40 cheaper than the Honeywell over the course of three years.

But the SU-9210 provides a significantly worse overall experience. The hand-wash-only tank is made of several plastic pieces fused together, and we worry about it leaking over time. It also tends to tip over while you’re filling it, so you have to stand there holding it steady. The SPT’s display is brightly lit and can never be shut off, making it hard to use in a bedroom or nursery, and it also beeps loudly upon every button push, which compounds the problem.

If the Honeywell HCM-350 is sold out and you need an evaporative humidifier immediately or temporarily, the SPT SU-9210 is an acceptable substitute. For long-term livability, however, the Honeywell is a much better choice.

Upgrade pick: Levoit LV600HH

Upgrade pick

The Levoit LV600HH Hybrid Ultrasonic Humidifier is a beautifully designed, powerful ultrasonic humidifier, and it’s our pick for large spaces (like a living room–dining room) and exceptionally dry homes (wood-heated or forced-air). Its 6-liter/1.5-gallon tank can go for more than 24 hours between refills, meaning fewer trips to the sink (we got 27 hours, on medium, running nonstop, in a steam-heated New York City apartment). Its accurate humidistat maintains the humidity at your desired level. And it’s easy to live with: It’s very quiet, cleaning the tank is simple, and, in a thoughtful touch, the lighted display can be shut off—so it won’t disrupt anyone’s sleep. Among its downsides—as with all ultrasonic humidifiers—it has to stand above the floor to minimize the risk of puddling, and it can create a layer of white dust on surfaces if your water supply contains a lot of minerals. And its base unit is fussier to clean than it needs to be, owing to a design with lots of nooks and crannies. Overall, the Levoit is an exceptional humidifier, but it’s more powerful than most people need, and it’s usually a bit more expensive than our top pick.

The Levoit consistently placed at or near the top in our real-world test in overall humidification (see How we tested), and its humidistat, unlike on many models we have tested, proved accurate, tracking within five points of what the data loggers registered. That means you can set a target humidity and the machine will turn itself on and off to keep the air at that level. That said, we don’t consider a humidistat necessary on every humidifier—evaporative models, like the top-pick Honeywell HCM-350, naturally stabilize the humidity at a comfortable level.

The Levoit’s large tank (1.5 gallons) means the machine can run for a long time between refills—Levoit claims 30-plus hours, and we got 27 hours with the machine running continuously on medium. Our top pick, the Honeywell, with a 1-gallon tank, typically requires at least one refill during a 24-hour period. Combined with the powerful ultrasonic mechanism, this tank capacity makes the Levoit a better choice for very large rooms or very dry homes; generally, wood-heated and forced-air-heated homes are drier than those with steam heat.

We really appreciated a number of design features on the Levoit, such as a tank that lies flat while you’re filling it (letting you do something else in the meantime—a 1.5-gallon tank takes a while to top up). The tank’s fill hole is also large enough that you can reach inside for a thorough cleaning.

Best of all, the Levoit lets you shut off the bright display at night (you hold down the Auto button for a few seconds). That makes it far nicer to use in a bedroom or nursery than most machines (though our top pick is also sleep friendly, with just a tiny, dim bulb indicating that it’s on).

The LV600HH, even among the ultrasonics we’ve tested, is extremely quiet: We measured 35.2 decibels at 1 meter (on low, medium, and high), versus about 40 on other ultrasonic machines. Nevertheless, in a quiet room you can hear it, and like all ultrasonic models it emits a mechanical hum that’s not as restful as the white noise that evaporative humidifiers, like our top pick, produce.

Several of the Levoit’s few drawbacks are common to all ultrasonic humidifiers: It has to sit on a table or shelf, to give the mist time to evaporate before puddling on the floor; hard water can produce a white dust settling on surfaces near the machine; and it can potentially overhumidify a room. (In this regard, we don’t like that the Levoit’s Auto setting targets a humidity of 68 percent—that’s well above the 60 percent threshold for promoting mold and mildew. To be on the safe side, manually set the target humidity to 60 percent or below.)

One downside specific to the Levoit LV600HH is the complex water channel and chimney in the base unit, which both have a number of tight nooks and crannies where gunk can accumulate. Cleaning them isn’t difficult—a small brush really helps—but it’s needlessly fussy. We hope Levoit will emulate the simple, cranny-free design of the Honeywell HCM-350 in future iterations. The Levoit is also usually a bit more expensive up front than the Honeywell, but because it has no parts that need regular replacing, its long-term cost may actually be a bit lower.

But the Levoit’s strengths are many, and in truth it was a contender for our top pick. We stayed with the Honeywell for a few reasons, chief among them that model’s proven durability and exceptionally user-friendly design. Again, at least eight Wirecutter staffers have owned a Honeywell HCM-350, sometimes for years, and we’ve never had one break down. And it’s simply the easiest humidifier we’ve ever found to clean and refill. Compared with many competitors, the Levoit LV600HH earns a solid A- in those respects—but the Honeywell gets an A+. And the Honeywell is powerful enough for most people’s needs, as it’s effective in spaces of up to 400 square feet, far larger than most bedrooms and living rooms.

After three weeks of running the Levoit, guide author Tim Heffernan noted a few more minor flaws. The hum it emitted, though quiet, was readily noticeable if the machine was sitting on a bedside table, and both he and his wife (who can sleep through almost anything) found it distracting. That necessitated placing the humidifier across the room, which meant bringing in a chair to place it on—not ideal in a cramped bedroom. On a day when the natural humidity was relatively high, the Levoit created a damp spot on the floor, because the mist didn’t have enough time to evaporate before it settled. The moisture wasn’t enough to cause damage, but evaporative humidifiers like the Honeywell don’t have this problem at all. The Levoit tank’s cap is slippery and hard to open when wet—which it always is when you pull the tank off the machine to refill it. Using a towel to grip the cap helps, but that’s an extra step; a toothier texture on its rim would eliminate the problem.

One last thing: The Levoit offers a warm-mist function. It works fine, but because warm mist is energy intensive, involves hot parts that can potentially cause a burn (see Some general words of caution), and doesn’t actually humidify any better than other methods, we recommend not using it.

Also great: Venta LW25

Also great

The Venta LW25 Airwasher performed extremely well in our tests and is impressively energy efficient, but it’s worthy of its high price tag only if you are willing to pay a lot more money up front for lower power consumption and less-frequent refills and cleanings. Though your typical humidifier requires thorough cleaning (wiping down all surfaces and descaling with vinegar) at least once a week, Venta recommends simply rinsing the LW25’s wet parts every 10 to 14 days and relying on a proprietary chemical mixture to keep the funk down. A two-week supply (3.5 ounces) is included with the LW25, and the replacement bottle holds 35 ounces, so it’s good for more than four months of use. Additional bottles will run you about $20.

The Venta works by drawing air over a set of slowly rotating disks. It draws just 7 watts on high (about one-sixth of a typical evaporative humidifier like our top pick), yet it’s extremely effective at humidifying, consistently performing at the top in our real-world test. We speculate that this result might be due to the water additives you use with it: quaternary ammonium chlorides (see our section on health risks for more on these) and a “water softening agent,” which increase the wet surface area for improved evaporation, disinfect the water, and reduce mineral buildup. However, despite the machine’s extreme efficiency and big, 2-gallon tank, Venta still recommends that you top it off every day in order to maintain maximum humidifying efficiency—it works best when full.

We were not impressed with its “air washing” abilities. To test whether this machine was comparable to an actual air purifier, we used a laboratory-quality benchtop optical particle counter that measured particles in the 0.5- to 20-micron range to measure airborne-particle concentrations before and after three hours of testing. Background particle concentrations ranged from 65 to 200 particles per cubic centimeter. At the end of the testing period, the Venta lowered the particle concentration from a starting concentration of 180 particles per cubic centimeter to a final concentration of 9, which sounds impressive until you consider that our top pick, the Honeywell HCM-350, which makes no claims of air purification, got the number down to 14 in a similar test. For reference, a HEPA-certified air purifier would bring the number down to virtually zero in less than half an hour.

The Venta LW25 is compact at 12 by 12 by 13 inches and 8.5 pounds, and it’s definitely a better choice than the other air washer we looked at, made by Winix, which cost $20 more, had a more complicated user interface, and used 0.58 gallon per day (nearly three times as much as the Venta). The Winix also used an inferior disk design that required the disks to be inserted only one way; the cover was similarly unidirectional. The Venta’s symmetric design avoids those drawbacks.

Despite its high sticker price and the moderately high cost of the chemicals (about $40 per year), the overall price tag of the Venta LW25 spread out over a three-year operating life is relatively low. At about $425 total (sticker price plus maintenance costs), it’s the second most expensive pick here, but an impossibly low electricity cost of just $15 makes it more affordable than you might expect.

Vicks V750 Warm Mist Humidifier

The Vicks V750 Warm Mist Humidifier performed above average in our fall 2015 testing, raising the humidity levels from 60 to 82.5 percent over a three-hour period. It is clearly built to its budget price, with cheap-feeling plastic and wobbly assembly. But hey, it’s cheap. Compared with its sister model, the Honeywell HWM705B Filter Free Warm Moisture Humidifier, it is slightly more solid, and in our tests the outside got less hot.

The Vicks is compact (10½ by 12½ by 5¼ inches and a feathery 3½ pounds). It has a 1-gallon tank with a comfortable handle and a mixing chamber that draws room air in to mix with the hot steam, so the moisture exiting is warm, not hot. A medicine cup allows you to add medications or essential oils. Operation is simple, via a two-setting switch with an unobtrusive night-light indicating water status: green during operation, and red when it has shut off after emptying the tank. We tested the humidifier on high (1.9 gallons per day), where the 1-gallon tank needs to be refilled every 12 hours. It features an auto shutoff (as do all steam models we tested). One note of concern: We’ve seen several reports of leaks occurring at any time from a couple of weeks to a year after purchase, but those reports constitute less than 10 percent of the reviews. Still, to be safe, you could place the V750 on spacers inside a plastic tub to catch any sudden leaks.

Some general words of caution about warm mist

Warm-mist humidifiers work by heating water until it turns to steam. And that means they have the potential to cause burns—both from the hot water and steam and from the heating element. Because of that risk, the American Academy of Pediatrics recommends against their use in homes with children. (Note: The Stadler Form Fred, which we tested, was a particularly bad offender in this regard, as its silvery plastic steam tube became extremely hot when the unit was on.)

Warm-mist humidifiers are no better or worse than evaporatives or ultrasonics at humidifying the air. But they do use a lot more energy. True, warm-mist humidifiers slightly heat the room, meaning you could perhaps turn down the thermostat a pinch. The other humidifier types produce a very slight cooling of the air in the room, which you’ll need to heat again (via a furnace or other heating system).

But do warm-mist humidifiers actually offset their energy costs by lowering your heating bill? John Holecek did a calculation in 2015, and the answer is no. Assume the humidifier sees use for three years (for six months each year) and dispenses 4 liters of water per day of use. Assume the home is heated with natural gas. For energy costs, John used his local California rates of 18¢ per kWh for electricity and $1.20 per therm for gas. The efficiency of both the electric humidifier (range 65 to 80 percent) and the gas furnace was set at 80 percent (range 78 to 97 percent).

Warm-mist humidifiers are no better or worse than evaporatives or ultrasonics at humidifying the air.

By figuring out the energy needed to heat the water from room temperature to near boiling (334 joules), and adding the extra energy needed to vaporize it (2,260 joules), we know the total energy (2,594 joules) needed per gram of water. Using these assumptions, if you heat that water with the humidifier, you will spend a whopping $355 in electricity versus just $81 in natural gas to supply the same amount of heat to your air. On top of the other downsides, warm-mist humidifiers are a bum deal.

What is a diaphragm pump? Also known as a Membrane pump that uses a combination of the reciprocating action of a rubber, thermoplastic or PTFE and suitable valves on either side of the body (check valve, butterfly valves, flap valves, or any other form of shut-off valves) to pump a fluid.

There are three main types of diaphragm pump. Those in which the pump is sealed with one side in the fluid to be pumped, and the other in air or hydraulic fluid. The diaphragm is flexed, causing the volume of the pump chamber to increase and decrease. A pair of non-return check valves prevent reverse flow of the fluid.

Those employing volumetric positive displacement where the prime mover of the diaphragm is electro-mechanical, working through a crank or geared motor drive, or purely mechanical, such as with a lever or handle. This method flexes the diaphragm through simple mechanical action, and one side of the diaphragm is open to air.

Those employing one or more unsealed sections with the fluid to be pumped on both sides. The diaphragm(s) again are flexed, causing the volume to change.

When the volume of a chamber of either type of pump is increased, the pressure decreases, and fluid is drawn into the chamber. When the chamber pressure later increases from decreased volume, the fluid previously drawn in is forced out. Finally, the diaphragm moving up once again draws fluid into the chamber, completing the cycle. This action is similar to that of the cylinder in an internal combustion engine. Pumps deliver a hermetic seal between the drive mechanism and the compression chamber, allowing the pump to transfer, compress, and evacuate the medium without a lubricant.

An elastomeric membrain can be used as a versatile dynamic seal that removes many of the limitations found with other sealing methods. They do not leak, offer little friction, and can be constructed for low pressure sensitivity. With the right material consideration, Yamada pumps can seal over a wide range of pressures and temperatures without needing lubrication or maintenance.

There are many different kinds of diaphragm pumps with different sizes and functions like Air Operated Diaphragm Pump, 1 Inch Air Operated Diaphragm Pump, 1.5 Inch Double Air Operated Diaphragm Pump,

2 Inch Air Operated Diaphragm Pump, 3 Inch Air Operated Diaphragm Pump, 25mm Air Operated Diaphragm Pump, 40mm Air Operated Diaphragm Pump, 50mm Air Operated Diaphragm Pump and the another most commonly used pump - Double Air Operated Diaphragm Pump.

A double diaphragm is a positive displacement pump which utilises two flexible diaphragms that reciprocate back and forth, creating a temporary chamber, which both draws in and expels fluid through the pump. The diaphragms work as a separation wall between the air and the liquid.

The first stroke

The two diaphragms that are connected by a shaft through the centre section where the air valve is located. The purpose of the air valve is to direct the compressed air to the back of diaphragm number one causing it to move away from the centre section. The number one diaphragm causes a press stroke moving liquid out of the pump. At the same time diaphragm number two is performing a suction stroke. The air behind diaphragm number two is being pushed out to the atmosphere causing atmospheric pressure to push the liquid to the suction side. The suction ball valve is pushed away off its seat allowing the fluid to flow past the ball valve into the liquid chamber.

The second stroke

When the pressurised diaphragm number one has reached the end of its stroke, the movement of the air is switched from diaphragm number one to the back of diaphragm number two by the air valve. The compressed air pushes diaphragm number two away from the centre block resulting in diaphragm number one being pulled toward the centre block. In pump chamber number two the discharge ball valve is pushed off its seat, whilst in pump chamber number one the opposite occurs. Upon completion of the stroke the air valve leads the air again to the back of diaphragm number one and restarts the cycle.

Use of Differential Pressure Transmitter and Common Troubleshooting

Differential pressure transmitter is a kind of pressure measuring instrument widely used in all kinds of chemical industry. Working principle of differential pressure transmitter is as follows. The differential pressure from the two-sided pressure pipes acts directly on the two-sided isolation diaphragm of the differential pressure transmitter sensor, and is transmitted to the measuring element through the sealing fluid in the diaphragm. The measuring element converts the measured differential pressure signal into the corresponding electrical signal and transmits it to the converter. After amplification and other processing, it becomes the standard electrical signal and then is output.

1. Measurement Objectives of Differential Pressure Transmitter

Differential pressure transmitter can not only measure the differential pressure value, but also measure the following three physical quantities through the analysis and calculation of the differential pressure value.

1.1 Pressure

You can just choose a section of pipe on the whole pipe to test its pressure, i.e. to detect the pressure of the pipe through differential pressure transmitter and secondary meter.

1.2 Flow

The differential pressure transmitter is installed through the pressure difference between the front and back of the flow orifice plate, which is matched with the square root secondary meter to measure the flow in the pipeline.

1.3 Resistance

If you want to measure the pressure difference between the inlet and outlet of the tower, you can install a pressure pipe at the inlet and outlet respectively, then connect the differential pressure transmitter, and finally match with the secondary meter to measure the tower resistance. In general, with the development of social industrialization and the continuous improvement of petrochemical and steel automation level, the application scope of differential pressure transmitter is more and more extensive. However, there is also increasing number of problems in production. For example, different installation, use and maintenance personnel make it more difficult to solve problems quickly, which affects the normal production to a certain extent, sometimes even endangers the production safety. Therefore, the field instrument maintenance personnel must have advanced techniques and skills for the instruments.

Understanding Compressors

Compressors are mechanical devices used to increase pressure in a variety of compressible fluids, or gases, the most common of these being air. Compressors are used throughout industry to provide shop or instrument air; to power air tools, paint sprayers, and abrasive blast equipment; to phase shift refrigerants for air conditioning and refrigeration; to propel gas through pipelines; etc. As with pumps, compressors are divided into centrifugal (or dynamic or kinetic) and positive-displacement types; but where pumps are predominately represented by centrifugal varieties, compressors are more often of the positive- displacement type. They can range in size from the fits-in-a-glovebox unit that inflates tires to the giant reciprocating or turbocompressor machines found in pipeline service. Positive-displacement compressors can be further broken out into reciprocating types, where the piston style predominates, and rotary types such as the helical screw and rotary vane.

In this guide, we will use both of the terms compressors and air compressors to refer mainly to air compressors, and in a few specialized cases will speak to more specific gases for which compressors are used.

Types of Air Compressor

Compressors may be characterized in several different ways, but are commonly divided into types based on the functional method used to generate the compressed air or gas. In the sections below, we outline and present the common compressor types. The types covered include:

Piston

Diaphragm

Helical Screw

Sliding vane

Scroll

Rotary Lobe

Centrifugal

Axial

Due to the nature of the compressor designs, a market also exists for the rebuilding of air compressors, and reconditioned air compressors may be available as an option over a newly purchased compressor, including special process gas compressors.

Piston Compressors

Piston compressors, or reciprocating compressors, rely on the reciprocating action of one or more pistons to compress gas within a cylinder (or cylinders) and discharge it through valving into high pressure receiving tanks. In many instances, the tank and compressor are mounted in a common frame or skid as a so-called packaged unit. While the major application of piston compressors is providing compressed air as an energy source, piston compressors are also used by pipeline operators for natural gas transmission. Piston compressors are generally selected on the pressure required (psi) and the flow rate (scfm). A typical plant-air system provides compressed air in the 90-110 psi range, with volumes anywhere from 30 to 2500 cfm; these ranges are generally attainable through commercial, off-the-shelf units. Plant-air systems can be sized around a single unit or can be based on multiple smaller units which are spaced throughout the plant.

To achieve higher air pressures than can be provided by a single stage compressor, two-stage units are available. Compressed air entering the second stage normally passes through an intercooler beforehand to eliminate some of the heat generated during the first-stage cycle.

Speaking of heat, many piston compressors are designed to operate within a duty cycle, rather than continuously. Such cycles allow heat generated during the operation to dissipate, in many instances, through air-cooled fins.

Piston compressors are available as both oil-lubricated and oil-free designs. For some applications which require oil-free air of the highest quality, other designs are better suited.

Diaphragm Compressors

A somewhat specialized reciprocating design, the diaphragm compressor uses a motor-mounted concentric that oscillates a flexible disc which alternately expands and contracts the volume of the compression chamber. Much like a diaphragm pump, the drive is sealed from the process fluid by the flexible disc, and thus there is no possibility of lubricant coming into contact with any gas. Diaphragm air compressors with spare parts are relatively low capacity machines that have applications where very clean air is required, as in many laboratory and medical settings.

Helical Screw Compressors

Helical-screw compressors are rotary compressor machines known for their capacity to operate on 100% duty cycle, making them good choices for trailerable applications such as construction or road building. Using geared, meshing male and female rotors, these units pull gas in at the drive end, compress it as the rotors form a cell and the gas travels their length axially, and discharge the compressed gas through a discharge port on the non-drive end of the compressor casing. The rotary screw compressor action makes it quieter than a reciprocating compressor owing to reduced vibration. Another advantage of the screw compressor over piston types is the discharge air is free of pulsations. These units can be oil- or water- lubricated, or they can be designed to make oil-free air. These designs can meet the demands of critical oil-free service.

Sliding Vane Compressors

A sliding-vane compressor relies on a series of vanes, mounted in a rotor, which sweep along the inside wall of an eccentric cavity. The vanes, as they rotate from the suction side to the discharge side of the eccentric cavity, reduce the volume of space they are sweeping past, compressing the gas trapped within the space. The vanes glide along on an oil film which forms on the wall of the eccentric cavity, providing a seal. Sliding-vane compressors cannot be made to provide oil-free air, but they are capable of providing compressed air that is free of pulsations. They are also forgiving of contaminants in their environments owing to the use of bushings rather than bearings and their relatively slow-speed operation compared to screw compressors. They are relatively quiet, reliable, and capable of operating at 100% duty cycles. Some sources claim that rotary vane compressors have been largely overtaken by screw compressors in air-compressor applications. They are used in many non-air applications in the oil and gas and other process industries.

Scroll Compressors

Scroll air compressors use stationary and orbiting spirals which decrease the volume of space between them as the orbiting spirals trace the path of the fixed spirals. Intake of gas occurs at the outer edge of the scrolls and discharge of the compressed gas takes place near the center. Because the scrolls do not contact, no lubricating oil is needed, making the compressor intrinsically oil-free. However, because no oil is used in removing the heat of compression as it is with other designs, capacities for scroll compressors are somewhat limited. They are often used in low-end air compressors and home air-conditioning compressors.

Rotary Lobe Compressors

Rotary-lobe compressors are high-volume, low-pressure devices more appropriately classified as blowers. To learn more about blowers, download the free Thomas Blowers Buying Guide.

Centrifugal Compressors

Centrifugal compressors rely on high-speed pump-like impellers to impart velocity to gases to produce an increase in pressure. They are seen mainly in high-volume applications such as commercial refrigeration units in the 100+ hp ranges and in large processing plants where they can get as large as 20,000 hp and deliver volumes in the 200,000 cfm range. Almost identical in construction to centrifugal pumps, centrifugal compressors increase the velocity of gas by throwing it outward by the action of a spinning impeller. The gas expands in a casing volute, where its velocity slows and its pressure rises.

Centrifugal compressors have lower compression ratios than displacement compressors, but they handle vast volumes of gas. Many centrifugal compressors use multiple stages to improve the compression ratio. In these multi-stage compressors, the gas usually passes through intercoolers between stages.

Axial Compressors

The axial Low-Pressure Water Lubricating Oil-free Compressor achieves the highest volumes of delivered air, ranging from 8000 to 13 million cfm in industrial machines. Jet engines use compressors of this kind to produce volumes over an even wider range. To a greater extent than centrifugal compressors, axial compressors tend toward multi-stage designs, owing to their relatively low compression ratios. As with centrifugal units, axial compressors increase pressure by first increasing the velocity of the gas. Axial compressors then slow the gas down by passing it through curved, fixed blades, which increases its pressure.

Power and Fuel Options

Air compressors may be powered electrically, with common options being 12 volt DC air compressors or 24 volt DC air compressors. Compressors are also available that operate from standard AC voltage levels such as 120V, 220V, or 440V.

Alternative fuel options include air compressors that operate from an engine that is driven off of a combustible fuel source such as gasoline or diesel fuel. Generally, electrically-powered compressors are desirable in cases where it is important to eliminate exhaust fumes or to provide for operation in settings where the use or presence of combustible fuels is not desired. Noise considerations also play a role in the choice of fuel option, as electrically driven air compressors typical exhibit lower acoustical noise levels over their engine-driven counterparts.

Additionally, some air compressors may be powered hydraulically, which also avoids the use of combustible fuel sources and the resulting exhaust gas issues.

Compressor Machine Selection in an Industrial Setting

In selecting air compressors for general shop use, the choice will generally come down to a piston compressor or a helical-screw compressor. Piston compressors tend to be less expensive than screw compressors, require less sophisticated maintenance, and hold up well under dirty operating conditions. They are much noisier than screw compressors, however, and are more susceptible to passing oil into the compressed air supply, a phenomenon known as “carryover.” Because piston compressors generate a great deal of heat in operation, they have to be sized according to a duty cycle—a rule of thumb prescribes 25% rest and 75% run. Radial-screw Variable Frequency Water Lubricating Oil-Free Screw Compressor can run 100% of the time and almost prefer it. A potential problem with screw compressors, though, is that oversizing one with the idea of growing into its capacity can lead to trouble as they are not particularly suited to frequent starting and stopping. Close tolerance between rotors means that compressor needs to remain at operating temperature to achieve effective compression. Sizing one takes a little more attention to air usage; a piston compressor may be oversized without similar worries.

An autobody shop which uses air constantly for painting might find a radial-screw compressor with its lower carryover rate and desire to run continuously an asset; a general auto-repair business with more infrequent air use and low concern for the cleanliness of the supplied air might be better served with a piston compressor.

Regardless of the compressor type, compressed air is usually cooled, dried, and filtered before it is distributed through pipes. Specifiers of plant-air systems will need to select these components based on the size of the system they design. In addition, they will need to consider installing filter-regulator-lubricators at the supply drops.

Larger job site compressors mounted on trailers are typically rotary-screw varieties with engine drives. They are intended to run continuously whether the air is used or dumped.

Although dominant in lower-end refrigeration systems and air compressors, scroll compressors are beginning to make inroads into other markets. They are particularly suited to manufacturing processes that demand very clean air (class 0) such as pharmaceutical, food, electronics, etc. and to cleanroom, laboratory, and medical/dental settings. Manufactures offer units up to 40 hp that deliver nearly 100 cfm at up 145 psi. The larger capacity units generally incorporate multiple scroll compressors as the technology does not scale up well once beyond 3-5 hp.

If the application involves compressing hazardous gases, specifiers often consider diaphragm or sliding-vane compressors, or, for very large volumes to compress, kinetic types.

Important Steps to Troubleshoot and Fix the Most Common Problems with AODD Pumps

Because of their simplicity, air operated double diaphragm pumps (AODD Pumps)are great for transfer applications. To achieve maximum performance, it is important to properly install and operate your pump. These six easy fixes will help you troubleshoot and fix common problems when your AODD is not working properly during installation and operation.

1.To Check The  Air Inlet Size And Pressure.

A small airline is the most common error with AODD pumps. To operate at its best, the pump requires compressed air. An airline that is too small will deprive it of the fuel it needs. Larger AODD pumps (one-inch and more) require more compressed and longer air lines than their smaller counterparts. For the correct size air line for your pump, refer to the manufacturer's instructions and operation manual. It is a good rule of thumb to match the size of the air line hose to the size of the inlet port on AODD pumps. Explore the latest AODD Pumps at Antlia Engineering Works. They are the AODD Pump Suppliers Globally.

Your pump's performance can also be optimized by adjusting the inlet pressure. Diaphragm pumps work in a 1:1 ratio. The pump's inlet pressure is directly proportional to the pump's outlet pressure. 100 psi is the target outlet pressure for a 50 gpm 1 inch pump. The pump's inlet pressure must also be greater than or equal to 100psi.

The outlet fluid pressure is affected by fluid viscosity, system back pressure, and fluid viscosity. Too little back pressure can cause the pump to run slower and the ball checks may not be as quick. If the fluid pressure exceeds the air pressure, the pump may stall. An air regulator is required to regulate the incoming pressure to ensure that an AODD pump performs at its best. An air regulator and the correct size air line will resolve most of the problems associated with AODD pump installation.

2.Check for Muffler Icing and Restrictions

Mufflers can be installed on AODD pumps and are recommended because they can produce high decibel levels at full speed. To operate the pump's air motor, compressed air is needed. Rapid temperature changes are caused by the compressed air entering the valve. It is then channeled through the pump's center section and exhausts through the muffler. The muffler exhaust temperature is below freezing and can lead to icing issues. This is more prevalent in environments with high humidity. Looking for AODD Pump Manufacturers In India.

Visit Antlia Engineering works, they manufacture all types of AODD Pumps.

If your pump is acting erratically, your inlet air contains high levels of moisture, or you can see the front of your muffler, these are indicators that your pump has icing issues. These solutions can help you eliminate icing issues and improve your pump's efficiency.

Pump the air pressure down

To operate at a lower speed (i.e.,. lower air pressure)

An exhaust port tube allows you to exhaust the air to remote locations

To collect condensation, add an air filter and a water catcher to your system.

To raise exhaust air temperature above freezing, install an air heater

To adjust the pressure dew point temperature, use an air compressor dryer

3.Checking Sealing Surfaces for Leaking

Leakage issues can occur with all types of pumps. These tips will ensure that your fluids remain in the pump and not the ground.

Follow the bolting pattern's illustration and torque the pump to the manufacturer's specifications.

When servicing your AODD pump, replace all PTFE o rings. Although PTFE can be used in many applications, it is not capable of returning to its original form after being compressed.

You can reduce the risk of leakage by properly torquing your pump according to the manufacturer's specifications and ensuring that sealing o-rings are replaced during service.

4. Ensure proper tubing and piping sizes

The flow rate of fluid required will determine the diameters of the pump's inlet and outlet ports. The size of the outlet and inlet hoses must be equal. This is a major concern because of the potential for cavitation, as well as the higher repair frequency and increased maintenance costs.

A pump that is 1 inch tall has a 1/2-inch inlet hose attached. The pump will not be capable of operating at its maximum capacity without cavitation. As the fluid viscosity increases, this risk is greater. To avoid cavitation, a pump of 1 inch should have an outlet and inlet hose of 1 inch. This will prevent costly and frequent repairs.

AODD pumps should have flexible inlet and outlet connections. This is preferable to hard plumbed installations. As the pump speed increases, vibration increases. Vibration increases with pump speed. This increases the possibility of hard-plumbed connections being loosened, which can lead to leakage.

5. PRIME - LOWER THE PUMP

AODD pumps are a popular choice for applications that require self-priming. The AODD pumps draw fluid by creating a low-pressure zone within the fluid bowls. This is less than the atmospheric pressure (14.7 psi). If the air pressure is too high, the pump will not changeover quickly enough to allow the fluid to flow into it.

This is solved by using the air regulator to reduce the air pressure entering an air valve and slow down the pump. The pump speed can be reduced to ensure that the fluid supplied has sufficient time to reach the pump. After this, the pump can operate at a faster speed by increasing the air pressure.

6. CLEAR ALL FLUID LINE RESERVATIONS

Clearing any fluid line restrictions is the final step in ensuring optimal pump performance. Limitations can lead to increased maintenance, pressure loss and potential cavitation. This issue can be fixed by removing the following:

Valves that are partially or fully closed

Line kinks or clogs

Too many hoses or too long a distance

These six steps will resolve most of the problems associated with AODD pumps. This will allow you to produce more and not spend time trying to fix it. If you need more help troubleshooting and repairing your AODD pump contact one of our experts.
