Maintenance Tips for Extending the Lifespan of Your Water Pressure Vessel

Proper maintenance of your water pressure vessel is essential for ensuring its longevity and efficient operation. Regular upkeep not only extends the lifespan of the vessel but also prevents common issues such as pressure fluctuations, leaks, and premature pump failure. In this guide, we'll explore essential maintenance tips that will help you keep your water pressure vessel in top condition.

1. Regular Pressure Checks

Monitor System Pressure:

Regularly check the pressure in your vessel using a pressure gauge. Ensure that the pressure is within the recommended range specified by the manufacturer. If the pressure is too high or too low, it can strain the vessel and the entire system.

Adjust Air Pressure:

For bladder or diaphragm tanks, periodically check the air pressure in the vessel. This can be done by turning off the system, draining the water, and measuring the air pressure with a tire gauge. The pressure should be slightly below the pump’s cut-in pressure (usually 2 psi lower). If needed, adjust the pressure using an air compressor.

2. Inspect for Leaks and Corrosion

Check for External Leaks:

Inspect the vessel and connecting pipes for any signs of leaks. Look for water stains, rust, or puddles around the base of the vessel. Address any leaks promptly, as even small leaks can lead to significant water loss and damage over time.

Examine the vessel’s exterior, especially around welds and fittings, for signs of corrosion. Corrosion weakens the structure of the vessel and can lead to leaks or failure. If you notice rust or corrosion, consider treating the area or replacing the vessel if the damage is extensive.

3. Test the Bladder or Diaphragm

Bladder Integrity:

For pressure vessels with a bladder or diaphragm, it's important to ensure that these components are intact. A ruptured bladder will cause the air and water to mix, leading to waterlogging and inconsistent pressure. If you suspect a bladder failure, you may notice that the pump cycles frequently or that the vessel feels heavy and full of water even after draining.

Test for Waterlogging:

To test, turn off the pump and drain the vessel. If water continues to come out even when the vessel should be empty, it may indicate a bladder failure. In such cases, replacing the bladder or the entire vessel may be necessary.

4. Clean and Maintain the Area Around the Vessel

Keep the Area Dry:

Ensure the area around the vessel is dry and free from moisture, which can promote rust and corrosion. Avoid placing the vessel in damp or humid environments, and consider using a dehumidifier if necessary.

Clear Debris:

Remove any debris, dust, or clutter around the vessel that could block access or cause damage. Ensure that there is adequate space around the vessel for air circulation and easy access for maintenance.

5. Schedule Regular Professional Inspections

By accurately measuring the pressure difference, the transmitter can determine the liquid level and provide valuable data for process monitoring and control.

How Does a Differential Pressure Level Transmitter Work?

The operation of a differential pressure level transmitter is based on the following key principles:

Basic Concept of Differential Pressure: The pressure exerted by a liquid column is directly proportional to its height. The greater the height of the liquid, the higher the pressure at the bottom of the tank or vessel. Differential pressure level transmitters measure the pressure difference between two points, typically the bottom and the reference point at the top or side of the tank.

Pressure Sensing: The transmitter has two pressure ports – one connected to the bottom of the tank (high-pressure side) and the other connected to the top or a reference point (low-pressure side). The high-pressure side measures the pressure due to the liquid column, while the low-pressure side measures the pressure above the liquid, often atmospheric pressure.

Diaphragm Movement: The pressure difference causes a diaphragm within the transmitter to deflect. This deflection is proportional to the differential pressure.

Conversion to Electrical Signal: The deflection of the diaphragm is converted into an electrical signal using various sensing methods such as capacitance, piezoelectric sensors, or strain gauges. This electrical signal is then processed and calibrated to represent the liquid level.

Output Signal: The transmitter provides an output signal (typically 4-20 mA or a digital communication protocol like HART) that corresponds to the liquid level in the tank or vessel. This output can be used for monitoring, display, or control purposes.

Common troubleshooting of laboratory centrifugal pumps

What faults can centrifugal pumps encounter in the laboratory, and how can these conditions be eliminated? Let's take a look. Diaphragm pumps 1. During use, the motor often fails to start, such as when the main power indicator light is on. At this time, the degree of carbon brush wear should be checked. If the carbon brush wear exceeds one-third of the total amount, it should be replaced with a new one in a timely manner. When the main power indicator light is not on, check if the indicator light fuse and indoor distribution board fuse are blown, and also check if the power cord is in good contact. If the fuse is broken, replace the fuse and keep the circuit smooth. The screw pump should also check the vacuum pump gauge and oil pressure indicator values. If the oil pressure is too high and the main engine cannot be started, it is necessary to check whether each oil circuit is blocked, especially whether the throttle hole is smooth. If it is not smooth, it should be cleaned to make it smooth. 2. If the bearing is damaged or its rotation is hindered, there is a lack of oil in the bearing or there is a lot of dirt in the bearing, which causes an increase in friction resistance. If the motor cannot reach the rated speed, the bearing should be cleaned or replaced in a timely manner. There is a layer of oxide on the surface of the commutator, even if it is burnt into unevenness or the brush does not match the outer edge of the commutator, which can cause a decrease in speed. The commutator and brush should be cleaned to ensure good contact. If there is a short circuit or open circuit in the rotor coil of a centrifugal pump, a multimeter can be used to check and rewind the coil. The rotor can cause rupture of the centrifuge tube, sample leakage, and rotor damage during use due to metal fatigue, overspeed, overstress, chemical corrosion, improper selection, imbalance of the rotating head during use, and temperature runaway. For the above situations, it is mainly required for the operator to master the operating procedures proficiently, select appropriate centrifugal pipes and rotors correctly, pay attention to strictly controlling each step of operation sequence, minimize unnecessary human damage, and use the rotor within the safety factor and warranty period. Magnetic pump 3. One of the reasons for the poor starting and cooling performance of the refrigerator is that the power supply is not available, and the power supply and fuse should be checked separately. If the voltage is too low and the safety device malfunctions, it can also prevent the refrigerator from starting. If the voltage is too low, it may be due to the low voltage of the power grid; Excessive wiring on the distribution board; The power cord is too long (ideal length is 3 meters), etc. Insufficient power cord capacity not only reduces voltage, but also causes accidents. Sewage pump 4. When the power supply voltage drops to 180-190VJ, the refrigerator cannot start, affecting the cooling effect. Poor ventilation performance, such as when the instrument is installed in direct sunlight or poorly ventilated areas, poor radiator effect, or the radiator cover is covered with dust, can also affect the cooling effect. The weight of the centrifuge tube is unbalanced and placed asymmetrically; There are foreign objects in the rotor hole, causing imbalanced load; Loose fixing nut at the upper end of the shaft, friction or bending of the shaft; The motor rotor will generate noise if it is not in the center of the magnetic field; Damage to the rotor itself can cause severe vibration and abnormal noise in the body. Self priming pump Many times, it is caused by incorrect operation. After identifying the cause, correct operation can eliminate the abnormal phenomenon. During the work process, if any abnormal phenomena occur, the machine should be immediately shut down and forced operation is not allowed to avoid unnecessary losses or accidents.

Intake and Compression: The pump draws in low-pressure oxygen or air from the inlet. Inside the compression chamber, either pistons or diaphragms create a confined space. As these components move, the gas volume decreases, leading to compression. This process raises the pressure of the gas.

Valves Regulation: Intake and exhaust valves control the flow of gas into and out of the compression chamber. During the compression stroke, the intake valve opens to allow gas in, while the exhaust valve remains closed to prevent backflow.

Pressure Increase: The repetitive movement of pistons or diaphragms continues to compress the gas, progressively increasing its pressure within the compression chamber.

Cooling: The compression process generates heat, which can be harmful. A cooling system dissipates this heat, preventing overheating and ensuring safe operation.

Pressure Monitoring: Pressure gauges provide real-time pressure readings, allowing operators to monitor and adjust the compression process to achieve the desired pressure level accurately.

Pressure Relief: A pressure relief valve ensures that the gas doesn't exceed safe pressure limits. If pressure becomes too high, the valve releases excess gas, preventing over-pressurization.

Outlet Discharge: Once the desired pressure is achieved, the high-pressure oxygen is discharged through the outlet connection, ready for distribution or storage.

By following these steps, an oxygen booster pump efficiently increases the pressure of oxygen or air, catering to diverse applications like medical facilities, industrial processes, and more. It ensures a reliable supply of high-pressure oxygen while adhering to safety standards.

Main Applications of Oxygen Booster Pumps

Oxygen booster pumps find essential applications in various industries where a reliable and elevated supply of high-pressure oxygen is crucial. Some main applications include:

Medical Facilities: Oxygen booster pumps ensure consistent high-pressure oxygen supply for medical applications, such as respiratory therapies, anesthesia, and life support systems.

Industrial Processes: Industries like metal cutting, welding, and glass manufacturing rely on oxygen booster pumps to provide elevated pressure for efficient combustion and chemical reactions.

How to Install and Maintain a Pressure Reducing Valve

Installing and maintaining a Pressure Reducing Valve (PRV) is crucial for balanced water pressure. Installation involves attaching the PRV downstream, adjusting pressure settings, and ensuring proper connections. Regular maintenance includes leak checks, corrosion inspection, and filter cleaning. Proper PRV care ensures efficient plumbing performance and prevents damage to pipes and fixtures.

Understanding PRVs: Exploring the Basics and Functions

Pressure Reducing Valves (PRVs) play a crucial role in maintaining balanced water pressure within plumbing systems. These devices are essential components that help regulate the pressure of water entering a building from the main supply. By understanding the basics and functions of PRVs, you can ensure the efficient operation of your plumbing system.

PRV are designed to address the varying water pressures that can occur in municipal water supplies. In some areas, the water pressure from the main supply can be too high, leading to potential damage to pipes, appliances, and fixtures. On the other hand, low water pressure can result in reduced water flow and inefficient performance.

The primary function of a PRV is to reduce the incoming water pressure to a safe and optimal level before it enters the building's plumbing system. This is achieved by using a diaphragm or piston mechanism that adjusts based on the pressure differential. As the water flows through the valve, the diaphragm or piston responds to changes in pressure, allowing the valve to open or close accordingly.

Installation Guide: Steps to Properly Install a PRV

Proper installation of a PRV is essential to ensure its effectiveness and longevity. Follow these steps for a successful installation:

Locate the Installation Site: Choose a suitable location downstream from the main water supply. Ensure there is enough space and access for the PRV.

Shut Off the Water: Turn off the main water supply to your building to prevent water flow during installation.

Attach the PRV: Using threaded connectors, attach the PRV to the designated location. Follow the manufacturer's instructions for proper connection.

Install a Pressure Gauge: Place a pressure gauge after the PRV to monitor and adjust the pressure accurately.

Adjust the Valve: Use the adjustment screw or knob on the PRV to set the desired water pressure level. Refer to manufacturer guidelines for optimal pressure.

Turn On Water Supply: Once the PRV is installed and adjusted, turn the main water supply back on. Check for leaks around the PRV and connections.

Pressure Regulation: How PRVs Maintain Optimal Water Flow

PRVs maintain optimal water flow by ensuring that the pressure entering the plumbing system remains consistent and within a safe range. When the water pressure from the main supply is too high, the PRV reduces it to a suitable level, preventing excessive force within the pipes.

By regulating pressure, PRVs prevent water hammer, a phenomenon where abrupt pressure changes lead to noisy vibrations and potential damage to pipes. Additionally, PRVs protect appliances and fixtures from the stress of high water pressure, extending their lifespan and reducing the need for repairs.

Maintenance Essentials: Keeping Your PRV in Top Condition

To ensure the continued functionality of your PRV, regular maintenance is essential. Follow these maintenance tips:

Visual Inspection: Periodically check the PRV for signs of leaks, corrosion, or physical damage.

Pressure Testing: Use a pressure gauge to verify that the PRV is maintaining the desired pressure level.

Filter Maintenance: Clean or replace filters within the PRV to prevent debris from affecting water flow.

Lubrication: If applicable, lubricate moving parts according to the manufacturer's recommendations.

Professional Inspection: Consider scheduling regular inspections by a plumbing professional to identify and address potential issues.

Troubleshooting PRV Issues: Common Problems and Solutions

Despite proper installation and maintenance, PRVs can encounter issues. Here are some common problems and their solutions:

Pressure Fluctuations: If you notice inconsistent water pressure, check for leaks in the PRV or surrounding pipes.

Water Hammer: Noisy vibrations can indicate water hammer. Adjust the PRV's pressure settings or install water hammer arrestors.

Leakage: Leaks might occur due to faulty connections or worn-out seals. Inspect and replace damaged components.

Clogging: Reduced water flow could be caused by clogged filters. Clean or replace filters as needed.

Failure to Regulate Pressure: If the PRV fails to maintain the desired pressure, it might be malfunctioning. Contact a professional for diagnosis and repair.

Understanding the fundamental aspects of PRVs, following proper installation guidelines, regulating pressure, performing routine maintenance, and addressing common issues will help you harness the benefits of these essential devices for a reliable and efficient plumbing system.

Conclusion:

In conclusion, our PRV stands as a dependable solution for maintaining precise water pressure levels within plumbing systems.

What is Gauge Pressure, and How Do We Measure it?

If you’ve ever been curious about the term “gauge pressure,” you’re not alone. It’s a term used in many industries, but unless you’re a pressure gauge enthusiast, you might not have encountered it before. In this blog post, we’ll break down what a pressure gauge is, how it’s measured, and some of the instruments used to do so. Let’s dive right in, shall we?

What is Gauge Pressure?

Gauge pressure is the pressure of a substance, such as gas or liquid, relative to the pressure of the surrounding atmosphere. It’s essentially the difference between the pressure inside a vessel and the pressure outside of it. For example, if the pressure inside a tire is 35 PSI (pounds per square inch) and the atmospheric pressure is 14.7 PSI, the gauge pressure would be 20.3 PSI (35 – 14.7 = 20.3).

Gauge pressure is used in many industries, including but not limited to, manufacturing, oil and gas, and aviation. It’s an important measurement for ensuring the safe and efficient operation of equipment and processes.

How is Gauge Pressure Measured?

So, how do we measure this pressure? Well, there are a few ways, but let’s focus on the most common one: the good old pressure gauge. This little guy looks like a clock, but instead of telling time, it tells you the pressure in pounds per square inch (PSI). And no, it doesn’t have little hands that move around, but it does have a needle that goes up and down.

To use a pressure gauge, you need to connect it to the pipe or container you want to measure. You do this by using a fitting that screws onto the pipe or container and has a hole for the gauge to screw into. Once you have it connected, you can start measuring the pressure.

And how do you read the gauge? Well, that’s very easy.  Just look at where the needle is pointing. If it’s pointing to the left, that means the pressure is low. If it’s pointing to the right, that means the pressure is high. And if it’s pointing straight up, that means the pressure is just right.

However, be careful not to confuse gauge pressure with absolute pressure. Absolute pressure takes into account the atmospheric pressure around us, while gauge pressure only measures the pressure inside the container or pipe.

Types of Pressure Gauges

There are many different types of pressure gauges available, each with its own unique set of features and benefits. Here are a few of the most common types:

Bourdon tube gauges. These gauges use a curved tube that expands and contracts as pressure changes. The movement of the tube is then translated into a readable output. Bourdon tube gauges are commonly used in industrial applications and can measure a wide range of pressures.

Diaphragm gauges. These gauges use a flexible diaphragm that deforms as pressure changes. The deformation of the diaphragm is then measured and translated into a readable output. Diaphragm gauges are commonly used in applications where the pressure being measured is relatively low, such as in medical equipment.

Piston gauges. These gauges use a piston that moves as pressure changes. The movement of the piston is then measured and translated into a readable output. Piston gauges are highly accurate but are also more expensive and complex than other types of gauges.

Pressure Gauge Calibration

Pressure gauge calibration it’s like giving your pressure gauge a check-up to make sure it’s reading pressure correctly. And doing it is very simple.

The first step to calibrating your pressure gauge is to get a calibration device. This can be something like a deadweight tester or a pressure comparator. Don’t worry, these sound complicated, but they’re just fancy machines that help you check your gauge’s accuracy.

Once you have your calibration device, it’s time to get down to business. First, you need to compare the pressure gauge’s readings to the readings on the calibration device. If they match up, congrats, your gauge is accurate! If not, don’t panic, we can fix this.

Now, it’s time to adjust your pressure gauge, so it reads the correct pressure. This involves turning a little screw on the back of the gauge to either increase or decrease the reading. It’s like tuning a guitar but for pressure.

Once you’ve made the necessary adjustments, it’s time to check the gauge’s accuracy again. This might involve repeating the process a few times until you get it just right. Once you do it, your pressure gauge is now calibrated and ready to go. It’s like giving it a spa day and a new outfit all in one. Just make sure to check it regularly to make sure it’s still reading pressure accurately.

Factors That Affect Gauge Pressure

Now, let’s talk about the factor that can affect gauge pressure. The first one it’s temperature. Just like how hot chocolate can burn your tongue, the temperature can affect pressure too. When things heat up, the molecules inside the container or pipe start moving faster, causing the pressure to increase. So, if you’re measuring pressure in a hot environment, make sure to take temperature into account.

Next up, we’ve got altitude. Just like how it’s harder to breathe at high altitudes, pressure can be affected too. The higher you go, the less atmospheric pressure there is, which means the pressure inside containers and pipes will be lowered too. So, if you’re measuring pressure in the mountains, make sure to adjust for altitude.

Third on the list is the type of fluid you’re dealing with. Different fluids have different densities and viscosities, which can affect pressure. Think of it like trying to suck a thick milkshake through a straw versus a thin smoothie. The thicker the fluid, the harder it is to move, which can affect pressure readings.

And last but not least, we’ve got blockages. Just like how a blocked sink can cause water pressure to drop, blockages in pipes and containers can affect pressure too. If there’s a blockage somewhere, the pressure on one side of the blockage will be higher than the other, which can give you inaccurate readings.

Using Gauge Pressure in Industry

Gauge pressure is an important measurement in many industries, as it can provide valuable information about the operation of equipment and processes. For example, in the oil and gas industry, gauge pressure can be used to measure the pressure of a well or pipeline, which can help to identify potential issues such as leaks or blockages.

Similarly, in manufacturing, gauge pressure can be used to monitor the pressure of a system or process, such as a hydraulic system or a steam boiler. By monitoring gauge pressure, operators can identify any deviations from normal operating conditions and take appropriate action to prevent equipment damage or downtime.

Conclusion

Remember, gauge pressure is simply the difference between the pressure in a container or pipe and the pressure in the surrounding atmosphere. And measuring it is as simple as using a gauge that’s designed to measure it. So next time you’re dealing with gauge pressure, don’t be intimidated. It’s just a matter of understanding the basics and being aware of the factors that can affect it. Content source: https://www.nemfg.com/sb/what-is-gauge-pressure-how-measure-it/

Your production line using the right dispenser for fluids?

In mass production lines, a proper fluid dispensing often leads to improved productivity, reduced wastage and increased profits. Selecting the right dispenser therefore becomes important.

Depending on your line of business and the types of materials used, you have plenty of options to choose from. Here is a guide to help you identify the factors you need to consider while choosing the right dispensing system for your needs.

Dispensers – by type of administering

Manual

These dispensers are affordable and convenient to use. They are used in general industry applications where repeatability is not required. Low on maintenance needs, they are a popular industry choice as they also do not need electricity to operate.

Foot Valve

Mounted on the floor, these use less desk space, and offer a higher degree of user control. Comprising a pressure regulator and a pressure gauge, the foot pedal is used to control the output and shot size. They are costlier than manual dispensers.

Programmable

Intuitive, efficient, and user-friendly, they can be programmed for various operating modes and dispensing routines.

Robotic

Due to the frequent mistakes and reduced productivity with injury-prone manual dispensing, robots are here to help – moulding easily in the Industrial Internet of Things (IIoT), providing a lot of data on the performance of the dispensing machines across locations for better business decisions. They can communicate with one another to handle complex manual tasks and also have machine vision for high precision dispensing.

Dispensing equipment types

Dispensing fluids has come a long way from the manual dispensing used earlier to the various types of equipment using different dispensing techniques today.

Manual Syringe System

This includes a plunger with a piston and a syringe filled with fluid. This method is suitable for low volume applications where product yields below 80% are acceptable, such as administering injections or collecting blood samples for testing.

Time/Pressure Dispensing (TPD)

This utilises air pressure coupled with a control timing circuit to increase product throughput. This provides a balance between cost and performance and is the most commonly used method. It uses the TPD valve which includes a pneumatic valve, a controller and a pressure reservoir.

Types of TPD valves

Pinch Tube Valve

This is used to dispense small dots or continuous beads of low viscosity fluid. Since the only part of the valve that makes contact with the fluid is the disposable pinch tube assembly, it is perfectly suited for applications that use quick curing adhesives or highly aggressive fluids that might damage the valve body.

Diaphragm Valve

More resilient than the Pinch Tube Valve, it lasts for millions of cycles. The diaphragm is made of Ultra High Molecular Weight Polyethylene (UHMWPE) making it the best choice to dispense moisture sensitive and low to medium viscosity fluids such as moisture sensitive adhesives for general bonding applications and UV cured adhesives in the medical device industry.

Needle Valve

This is ideal for applications that require micro dot size (less than 0.002cc), such as UV adhesive used in hearing aids. Except moisture sensitive fluids and quick curing adhesives, fluids such as UV adhesives, solvents, inks, oils and primers are recommended.

Spool Valve

To dispense high viscosity fluids in high volume applications heavy-duty spool valves are used. Fluids such as silicones, greases and sealants are dispensed using this type of valve.

Choosing the right dispenser from the right partner

A reliable partner is required who not only manufactures a wide range of dispensers, but can also advise you on the right dispensing solution for your requirement after understanding your need which depends on various factors such as:

Access to Electricity

If you plan to use the dispenser in a remote or rural location without access to electricity, then manual dispensing is best suited for you. Not only does it cost less, but it also does not need electricity.

Availability of Space

If available space in your facility is less, then Foot Valve should be your choice as it requires less desk space. What’s more, it is more accurate and efficient than manual dispensing.

Type of Application

By controlling the settings in programmable dispensers, users can dispense the fluid with utmost precision. Also, these dispensers can handle both high and low viscosity fluids. Manual dispensers are unsuited for high viscosity fluids.

Budget

After considering all factors, you may decide based on your budgetary constraints.

MELSS brings you the widest range of fluid dispensers from the leaders – Techcon Systems who are credited with many fluid dispensing innovations, such as:

Rotary Displacement Dispensing which can not only handle viscosity fluctuations, but can also handle higher viscosities of 30,000cps or higher, handling solder pastes, surface mount adhesives, silver filled epoxies and encapsulant materials used in the electronics industry.

Progressive Cavity Pump which is impervious to changes in viscosity or any other variable that can impact dispense volume, resulting in an accuracy of 99% or higher.
