Description

Air conditioner oil pump with thrust structure Technical Field The utility model relates to the technical field of air conditioner compressors, in particular to an air conditioner oil pump with a thrust structure. Background The air conditioner compressor is a refrigerant circuit for compressing and driving the refrigerant. The air-conditioning compressor extracts the refrigerant from the low-pressure area, sends the refrigerant to the high-pressure area after compression, cools and condenses, and emits heat to the air through the radiating fins, the refrigerant also changes from a gaseous state to a liquid state, and the pressure is increased, wherein the oil pump for the air-conditioning compressor is used for conveying the refrigeration lubricating oil in the compressor. But the internal structure of the oil pump for the existing air conditioner compressor is simpler, and a certain thrust mechanism is lacked at the oil inlet of the oil pump, so that the application range of the oil pump is affected. Disclosure of utility model The utility model aims to solve the problem that a certain thrust mechanism is lack at an oil inlet of an oil pump provided in the background art, and provides an air conditioner oil pump with a thrust structure. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The utility model provides an air conditioner oil pump with thrust structure, includes the main pump body, the middle part both sides of the main pump body are equipped with oil inlet and oil-out respectively, the internal fixed outer rotor that inserts of main pump is equipped with, the outer rotor internal rotation is connected with the inner rotor, the one end that the inner rotor is close to the oil-out rotates and has cup jointed thrust bearing, one side that the main pump body is close to the oil-out is equipped with the ring channel that corresponds with thrust bearing, be equipped with fool-proof hole and locating hole that corresponds with thrust bearing in the ring channel. Preferably, a plurality of stepped holes are formed around the edge of the main pump body. Preferably, the edge of the thrust bearing is fixedly connected with a thrust bearing riveting groove, and a limit groove corresponding to the thrust bearing riveting groove is arranged in the annular groove. Preferably, a sealing piece is inserted between the thrust bearing and the inner rotor. Preferably, the surface of the thrust bearing is coated with a cusn+ptfe composite layer. Preferably, a plurality of supporting ribs (11) are arranged around one end, close to the oil inlet (2), of the main pump body (1). Compared with the prior art, the utility model has the following beneficial effects: According to the utility model, the thrust bearing is arranged on the oil outlet side of the oil pump, so that the lubrication effect of the thrust bearing is better, the service life of the thrust bearing is prolonged, and the thrust bearing can replace a thrust mechanism on an external linkage device, thereby effectively reducing the installation cost and improving the application range of the oil pump.
