What Are Industrial Air Compressors? Exploring Different Types and Uses

Industrial air compressors are integral to modern manufacturing and industrial processes, providing the power needed for various applications such as construction, automotive repair, and heavy machinery operation. Their ability to compress air into a stored energy form makes them valuable tools in industries requiring consistent and reliable power sources. This blog will explore what industrial air compressors are, delve into the different types, and examine their varied uses across sectors.

What Is an Industrial Air Compressor?

At its core, an industrial air compressor is a mechanical device that converts power into potential energy stored in pressurized air. The compressor takes air from the atmosphere, compresses it to a higher pressure, and then stores this energy in a tank or releases it to power various tools and machinery. The stored compressed air can be used to generate mechanical force, such as running pneumatic drills, driving motors, or operating equipment.

Air compressors come in different sizes and capacities, from small portable units for smaller jobs to large industrial machines designed for continuous use. The type and size of the compressor depend on the specific needs of the industry, ranging from light to heavy-duty applications.

How Industrial Air Compressors Work

The basic working principle of an industrial air compressor revolves around drawing air from the atmosphere, compressing it through mechanical action, and storing the compressed air in a tank or cylinder for future use.

HIGH-PRESSURE COMPRESSED AIR FOR BRAKING POWER

Automobile Market in India

India is the 4th largest producer of automobiles in the world, with an average annual production of more than 4 million motor vehicles. As per the reports, the Indian passenger car market is expected to reach USD 160 billion by 2027 while registering a CAGR of over 8.1% between 2022-27. India could be a leader in shared mobility by 2030. As a result, many manufacturers are investing in new manufacturing plants and increasing capacities in existing plants to cater to the increasing demand.

Overview

Brakes are one of the most critical parts of the active safety systems in automobiles. Better the brakes, the safer the vehicle. Based on the power source, brakes are classified as follows.

Mechanical braking system

Hydraulic braking system

Air or pneumatic braking system

Vacuum braking system

Magnetic braking system

Electric braking system

Out of the above, hydraulic brakes, especially disc brakes, are used predominantly in modern-day automobiles because of higher reliability, increased braking force, etc. Most cars manufactured today use the disc brake system; some manufacturers still use drums; however, their effectiveness diminishes in comparison to the disc brake.

Disc Brake Systems are most widely used in almost all modern-day vehicles, so the need for a good quality disc brake at optimum cost is extremely high. This, in turn, creates a market for more research to be done to optimize the product by keeping the safety intact, thereby creating a huge potential in the field of testing.

Disc Brake Operation

The disc braking system involves many different components, but at its most basic function, the system consists of a disc/rotor, a brake caliper, and brake pads. When the brake pedal is applied, brake fluid creates pressure, squeezing the brake pad against the rotor and creating friction. This friction slows the rotation of the wheels and the vehicle itself.

Brake calipers are a clamp-like component that fits over the disc. Their primary function is to push the brake pads into the disc, and they do this via pistons and hydraulic brake fluid. Inside the calipers are pistons, which have brake pads attached to them. When we put our foot on the brake, pressurized fluid is sent to the pistons, and they push against the pads, which come into contact with the disc surface.

Testing of Brake Calipers

No product reaches the user before it gets tested. Different products undergo different testing processes. Even though various braking system components are tested separately, the calipers should be tested after assembly for leakage and fault-free operation.

Though the hydraulic brake uses brake fluid for the operation, pneumatic testing with high-pressure air will be used in the testing process of the brake assemblies. Using high-pressure air relatively decreases the testing time and increases the life of components compared to hydraulic testing. It also prevents hydraulic oil spillage, thus maintaining a clean and safe work Environment.

Once the brake caliper components are assembled, high-pressure air will be filled and held inside the component. The Pressure range would be approximately 250 barg. In case of any leakages, there would be a drop in air pressure, and thus the leakages in the component will be identified.

The products passing the test parameters will be approved, and the components get rejected if there are any leakages.

Testing of Brake Hoses

Since the actual operation of these brakes is with hydraulic oil, the oil needs to be also fed at pressure to the callipers during operation. This is achieved by a hose connecting the fluid sump to the callipers.

Since the brake operation is at high pressure, the hose carrying also has to be rated at high pressure; thereby, they are also subject to high-pressure pneumatic testing to maintain overall safety.
