There are many types of air compressors (air compressors)

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

Air compressor classification

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, frequency conversion, explosion-proof and other air compressors.

4. According to usage, it can be divided into: refrigerator compressor, air-conditioning compressor, refrigeration compressor, oil field compressor, natural gas filling station, rock drilling machine, pneumatic tool, vehicle brake, door and window opening and closing, textile machinery Used, tire inflation, plastic machinery compressor, mining compressor, marine compressor, medical compressor, sandblasting paint.

5. According to the type, it can be divided into: fixed type, mobile type, closed type [1].

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, the compression element is a piston, in

Piston air compressor

Reciprocating movement in the cylinder.

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

Sliding vane compressor-is a rotary variable volume compressor, and its axial sliding vanes slide radially on the rotor eccentric to the same cylinder. The air trapped between the sliders is compressed and discharged.
