What are the types of air compressors?

An air compressor is a device used to compress gas. The structure of the air compressor is similar to that of a water pump. Most air compressors are of the reciprocating piston type, with rotating blades or rotating screws. Centrifugal compressors are very large applications.

There are many types of air compressors:

1. According to the working principle, it can be divided into three categories: volume type, power type (speed type or turbine type), thermal type compressor.

2. According to the lubrication method, it can be divided into oil-free air compressor and oil-lubricated air compressor.

3. According to performance, it can be divided into: low noise, variable frequency, explosion-proof and other air compressors.

4. According to the purpose, it can be divided into: refrigerator compressor, air conditioner compressor, refrigeration compressor, oil field compressor, natural gas filling station, rock drill, pneumatic tool, vehicle brake, door and window opening and closing, textile machinery Use, tire inflation, plastic machinery compressors, mining compressors, marine compressors, medical compressors, sandblasting and paint spraying.

5. According to the type, it can be divided into: fixed type, mobile type and closed type.

Positive displacement compressor-a compressor that directly relies on changing the gas volume to increase the gas pressure.

Piston compressor-is a positive displacement compressor, its compression element is a piston, reciprocating in the cylinder.

Rotary compressor-is a positive displacement compressor, compression is achieved by the forced movement of rotating elements.

The sliding vane compressor is a rotary variable-capacity compressor, and its axial sliding vane slides radially on a rotor that is eccentric with the cylindrical cylinder. The air trapped between the sliding plates is compressed and discharged.
