Where are compressors used?

With the rapid development of the national economy, compressors have become extremely widely used in industry. Compressors are called "general-purpose machinery" because of their wide range of applications. According to the different characteristics of compressed gas usage, they can be divided into the following types:

1. Compressed air as power:

- Driving various pneumatic machinery and tools with exhaust pressure at 7~8 kg/square cm.

- Controlling instruments and automation devices with pressure approximately at 6 kg/square cm.

- Automatic vehicle operations, door and window opening/closing with pressure at 2~4 kg/square cm.

- Stirring in pharmaceuticals and brewing industries with pressure at 4 kg/square cm.

- Filling weft yarns in jet looms with pressure at 1~2 kg/square cm.

- Starting medium and large diesel engines with pressure at 25~60 kg/square cm.

- Fracturing oil wells with pressure at 150 kg/square cm.

- Secondary oil recovery method with pressure approximately at 50 kg/square cm.

- High-pressure coal blasting with pressure approximately at 800 kg/square cm.

- In the defense industry, pressure-compressed air is used as a power source. For example, submarine submersion and surfacing, torpedo firing and propulsion, and salvage of sunken ships all use pressure-compressed air as their power source at varying pressures.
