There are many types of Hitachi compressors, which can be divided into positive displacement compressors, reciprocating compressors, centrifugal compressors according to their working principles. The working principle of positive displacement compressors is to compress the volume of gas, increasing the density of gas molecules per unit volume to increase the pressure of compressed air; The working principle of a centrifugal compressor is to increase the velocity of gas molecules, converting their kinetic energy into gas pressure energy, thereby increasing the pressure of compressed air. The working principle of a reciprocating compressor (also known as a piston compressor) is to directly compress gas, and when the gas reaches a certain pressure, it is discharged
