Abstract

The invention provides a pump body unit, a compressor and an air conditioning device. The pump body unit comprises a first structural body, a rolling bearing assembly, a second structural body, a third structural body and a main shaft. The main shaft penetrates through the first structural body, the rolling bearing assembly, the second structural body and the third structural body. The pump body unit comprises multiple lubricating oil lines. The multiple lubricating oil lines at least include the first lubricating oil line, the second lubricating oil line and the third lubricating oil line. The first lubricating oil line penetrates through the second structural body, a sliding sheet backpressure chamber of a rotor structure of the main shaft, a third structural body, the second structuralbody and a rolling body of the rolling bearing assembly. The second lubricating oil line penetrates through the sliding sheet backpressure chamber of the rotor structure of the main shaft, and a firstdecompression groove of the first structural body. The third lubricating oil line penetrates through the sliding sheet backpressure chamber of the rotor structure of the main shaft, the first structural body, and the rolling body of the rolling bearing assembly. With the pump body unit, the compressor and the air conditioning device, the problem that lubricating oil lines in a pump body unit in the prior art cannot meet the requirements of a pump body for lubrication is effectively solved.

Description

technical field [0001] The invention relates to the technical field of compressor equipment, in particular to a pump body assembly, a compressor and an air conditioner. Background technique [0002] On the one hand, the oil passage of the rotary vane compressor must ensure the lubrication of the friction pair. On the other hand, due to the special structure of the rotary vane compressor, it is necessary to provide back pressure to the moving blades through the oil passage to prevent the blades from detaching from the cylinder. Therefore, the oil circuit design and oil distribution of the rotary vane compressor are particularly important to the comprehensive performance of the compressor. [0003] At present, this type of compressor still has some disadvantages. Due to the limitation of the flange, it is difficult to dissipate the heat generated by the movement of the rolling elements of the bearing on the raceway, and poor heat dissipation will cause the compressor suction ...
