The role of lubricating oil

The role of lubricating oil 1) A dynamic seal is formed between the screw and the compression chamber and the male and female screws to reduce the leakage of refrigerant from the high-pressure side to the low-pressure side during the compression process. 2) Cooling the compressed refrigerant, the oil is injected into the compressor, absorbs the heat generated by the refrigerant gas during the compression process, and reduces the exhaust temperature. 3) An oil film is formed between the bearing and the screw to support the rotor and play a lubricating role. 4) Transmit the pressure difference force, drive the capacity adjustment system, adjust the position of the capacity adjustment slider through the action of the compressor loading and unloading solenoid valve, and realize the compressor capacity adjustment control. 5) Reduce operating noise. Description: The internal lubricant of the compressor is the key to maintain the normal operation of the compressor. The general lubricant problems are: 1) Foreign matter is mixed in, causing contamination of lubricating oil and blocking the oil filter. 2) The lubricating oil deteriorates due to the high temperature effect and loses its lubricating function. 3) System water pollution, acidification, erosion motor.
