The function of the compressor2

2、 According to different working methods, it can be divided into two categories - volume type and speed type. A positive displacement compressor relies on changes in the working chamber volume to achieve processes such as suction, compression, and exhaust. There are reciprocating compressors and rotary compressors belonging to this type of compressor. The speed type compressor relies on the high-speed rotation of the T wheel to do work on the steam, increase the pressure, and complete the task of transporting steam. There are centrifugal and axial compressors belonging to this type of compressor, and the centrifugal compressor is currently commonly used
