[0002] The refrigeration compressor unit is mainly composed of four major parts: refrigeration compressor, condenser, air cooler, solenoid valve, oil separator, liquid storage tank, oil sight glass, diaphragm hand valve, return air filter and other parts. During the operation of the refrigeration unit, a large amount of water will accumulate on the surface due to condensation, which will corrode the components of the refrigeration unit and cause the refrigeration unit to fail to work normally. Therefore, during the production process of the refrigeration unit, the sheet metal of the refrigeration unit needs to be painted to improve the surface performance of the sheet metal.
