Background
A compressor is a mechanism that compresses gas to raise the pressure of the gas, supplies electric power thereto through a generator such as a motor, a turbine, or the like, and performs a compression work on a working fluid such as air, a refrigerant, or the like to raise the pressure of the working fluid.

The basic working principle of the compressor is as follows: when the compressor is electrified and works, the stator 4 generates a magnetic field, the rotor 5 rotates to drive the shaft 6 to rotate, the piston 10 makes eccentric motion in the cylinder 9, and therefore low-temperature and low-pressure gas cold medium is compressed into high-temperature and high-pressure gas, the high-temperature and high-pressure gas is discharged into the shell 3 through the cylinder hole, the silencing cover 8 and the exhaust pipe and then is discharged into a refrigeration cycle system through the cutting edge on the outer side of the stator 4, the gap between the rotor and the stator and the circulation hole of the rotor 5. However, in the process, two fluids exist in the shell of the air-conditioning compressor, one is a refrigerant which can complete the refrigeration function; the other is engine oil for sealing and lubricating. When the air conditioner compressor works, a part of engine oil is atomized by a high-temperature and high-pressure refrigerant, the atomized refrigerator oil flows into the air conditioning system through the exhaust pipe along with a high-temperature and high-pressure gaseous refrigerant, and if the gaseous refrigerant contains more refrigerator oil, the heat exchange of a refrigerant medium in the air conditioning system is influenced, so that the energy efficiency of the air conditioner is reduced; meanwhile, due to the lack of refrigerating machine oil in the compressor shell, parts of the compressor can be seriously abraded, and further the lubricating property, the reliability and the service life of the compressor are reduced.
