Maintenance and maintenance of screw air compressor

1. Maintenance and maintenance of intake air filter element. The air filter is a component that filters air dust and dirt, and the filtered clean air enters the compression chamber of the screw rotor for compression. Because the internal clearance of the screw machine only allows particles within 15u to filter out.

Classification, principle and use of refrigeration compressors

Classification, principle and use of refrigeration compressors<br></br> The function of refrigeration compressor:<br></br> The refrigeration compressor is the "heart" of the refrigeration system. It absorbs the refrigerant vapor from the evaporator, increases the pressure and discharges it to the condenser, so that the refrigerant circulates in the system. Can be used in refrigeration systems and heat pump systems
