1. 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.
2. Advantages of air compressor:
1. Friction due to rotation is inevitable in structure.
2. The blade strength is limited to the rotation speed.
3. Disadvantages of air compressor:
1. Friction due to rotation is inevitable in structure.
2. The blade strength is limited to the rotation speed. When the rotation speed is high, the two-stage compression type is used, but the volume will increase.
3. High pressure cannot be made in structure.
