Compressor


A compressor is a machine that compresses the gas and increases gas pressure at the same time. It is widely used. Common application fields include: compressing refrigerants (such as refrigerators, HVAC, the principle is a heat pump and refrigeration cycle), compressed air (such as Air compressor), compressed gas (such as compressed hydrogen), providing compressed gas as industrial driving power, such as silicon chemical industry, petrochemical industry, natural gas transportation, etc. According to its operating principle, it can be divided into positive displacement compressor (or positive-displacement) and gas dynamic compressor (aerodynamic):

A compressor is a machine that compresses the gas and increases gas pressure at the same time. It is widely used. Common application fields include: compressing refrigerants (such as refrigerators, HVAC, the principle is a heat pump and refrigeration cycle), compressed air (such as Air compressor), compressed gas (such as compressed hydrogen), providing compressed gas as industrial driving power, such as silicon chemical industry, petrochemical industry, natural gas transportation, etc.
According to its operating principle, it can be divided into positive displacement compressor (or positive-displacement) and gas dynamic compressor (aerodynamic):
Positive displacement compressors introduce gas into a closed space, and increase the internal pressure by compressing the space volume spread by the original gas, thereby converting mechanical energy into pressure energy. According to the different compression methods, it can be divided into the reciprocating type and rotary type (such as scroll type, spiral type, etc.).
The gas-powered compressor uses the high-speed rotation of the impeller to force the gas to flow at a high speed to generate kinetic energy. During the process of passing through the booster ring, the increase in the cross-sectional area of ​​the re-permeability reduces the air flow rate, so that the kinetic energy of the gas is converted into pressure energy. causing the pressure to rise. At present, this type of compressor has centrifugal, axial flow, and so on.
According to the lubrication method, it can be divided into oil-free compressors and oil-lubricated compressors. According to performance, it can be divided into low noise, variable frequency, and explosion-proof. According to performance, it can be divided into fixed type, mobile type, and closed type.
