Gas compressors can generally be divided into the following categories based on their operating principles and structural features:
1. Reciprocating Gas Compressor: Reciprocating gas compressors compress gas through the back-and-forth motion of a plunger or piston. They have a simple structure and a high compression ratio, and are widely used in fields such as atmosphere compression and syngas.
2. Rotary Gas Compressor: Rotary gas compressors compress gas through the rotational motion of a rotor. The rotor surface typically features a helical shape, resulting in stable compression, low noise, and a long service life. They are widely used in fields such as air separation and power generation.
3. Centrifugal Gas Compressor: Centrifugal gas compressors compress gas through a high-speed rotating impeller. They have a high compression ratio and low energy consumption, and are widely used in fields such as industrial oxygen production and petroleum refining.
