What Is an Air Compressor and it’s Types?
A pneumatic tool called an air compressor uses electricity to release stored potential energy from compressed air. An air compressor raises the pressure in a storage tank. This is essentially achieved by using several techniques to push more and more air into the container.
When the intended maximum pressure is reached inside the tank, the air compressor turns off. The tank then stores the compressed air until it is required. Utilising the kinetic energy of the released compressed air after the tank depressurises allows for various uses for the power.
When the tank's pressure drops below the minimum, the air compressor restarts and pressurises the tank. A pump must be kept apart from online car accessories India like air compressor. This is because the former works with liquids while the latter only with gases or air.
Since you are aware that air can be compressed, all you need is the best car tyre inflator. With you already having an air compressor, the device draws air from one end and compresses it to high pressure. Finally, it sends it to the other end for various applications.
Characteristics of Air Compressors
Understanding the features of an air compressor that can handle your jobs will help you choose the best model. Plus, they will make your work easier:
- Oil-free pumps require less maintenance because they don't add oil to compressed air.
- Compared to a direct-drive system, a belt-drive system offers quieter operation.
- To avoid overload damage, thermal protection shuts down the motor.
- You can guide exhaust away from your work area by using adjustable exhaust.
- Without attaching and disengaging tools, multiple couplers let you accomplish various tasks.
- Tools and accessories like hoses, nailers, and blow guns increase the value of your purchase. Some compressors might not include air hoses.
- To enhance the amount of air you can store, you can buy auxiliary air tanks.
Air Compressors: The Many Variations
Air compressors can be divided into positive displacement and dynamic displacement subcategories based on how they function internally. You will most frequently see the following four types of air compressors:
- Reciprocating Air Compressor
- Centrifugal Compressor
- Axial Compressor
- Rotary Screw Compressor
To help you choose wisely for your project, the experts have discussed what each is best utilised for below.
Reciprocating Air Compressor
The reciprocating compressor is another well-liked variety of displacement compressors. These are often seen in smaller buildings, including garages and residential homes. The reciprocating compressor is not meant to operate continuously, in contrast to the rotary screw compressor.
A reciprocating air compressor performs more smoothly and has more functioning parts than a rotary screw compressor.
These air compressors compress and displace the air inside a cylinder to increase pressure. The pressure ranges that reciprocating compressors can achieve depend on whether single-stage or multi-stage.
Centrifugal air compressors use a diffuser to create potential energy by delaying and cooling the incoming energy. This may generate a large quantity of power from a piece of minimal equipment. The method of multi-phase compression is to blame for this.
Their maintenance requirements are lower than reciprocating or rotary screw compressors, and specific models may produce air without oil. Since they can have up to 1,000 horsepower, they are frequently utilised for more challenging building sites. The options include chemical factories or steel manufacturing facilities.
Rotary Screw Compressor
The simplest air compressors to maintain are those with standard displacement, like rotary screw compressors. This is essentially since their internal cooling system and little maintenance needs. These are substantial, industrial-sized devices that can operate without oil lubrication.
Energy for rotary screw air compressors comes from two internal, counter-rotating rotors. Air wedged between the two opposing rotors results in pressure building inside the housing. These air compressors are made for continuous usage thanks to their inbuilt cooling system. Do keep in mind that they have a power range of 5 to 350 horsepower.
Axial air compressors are more frequently seen in the high-speed engines of ships and airplanes than in construction projects. They can produce up to thousands of horsepower. However, these air compressors are substantially more expensive than other types. This is why they are primarily used in aerospace research despite having a high-efficiency rate.
Air Compressor Applications
A high volume of moderately pressed air can be supplied by industrial air compressors to power pneumatic tools. Additionally, air compressors are frequently used in drilling, mining, and oil and gas applications. They contribute significantly to aerate drilling fluids during underbalanced drilling and for air pigging of pipelines.
Most air compressors are rotary vane, screw, or reciprocating piston types. Keep in mind that reciprocating, rotary screw, and scroll air compressors are preferred for small and medium-sized applications. However, centrifugal compressors are frequently used in large applications.
Many tools used to be powered by intricate systems that included belts, wheels, and other substantial parts before air compressors were invented. This equipment was large, expensive, and complex for many small businesses. These days, air compressors can be found in various locations, including your neighbour’s garage, extensive shop floors, and auto workshops.
