Abstract

The application provides a pump body assembly, a compressor and an air conditioner. The pump body assembly includes a main shaft, an upper flange, a lower flange, a cylinder and rollers. The rollers are fixed circumferentially relative to the main shaft. A slide groove is arranged on the roller, and a slide is provided for sliding in the slide groove. The head of the cylinder abuts against the inner wall of the cylinder, a tail cavity is formed between the tail of the slide vane and the tail of the slide vane groove, the upper flange is provided with a first back pressure groove and / or the lower flange is provided with a second back pressure The groove, the main shaft is provided with a central hole and a side hole connected to each other, the tail cavity and the side hole are arranged in a dislocation along the circumferential direction of the roller, and the side hole communicates with the tail cavity through the first back pressure groove and the second back pressure groove. According to the pump body assembly of the present application, when the compressor in the prior art operates at high frequency, the back pressure is unstable and fluctuates greatly, which affects the energy efficiency and reliability of the compressor.

Description

technical field [0001] The present application relates to the technical field of air conditioning, in particular to a pump body assembly, a compressor and an air conditioner. Background technique [0002] In the existing rotary vane compressor, in order to ensure that the sliding vane can be extended smoothly during operation, a back pressure chamber is generally provided at the tail of the sliding vane (sliding vane tail cavity formed by the sliding vane and the main shaft sliding vane groove + the back pressure of the upper flange Groove + lower flange back pressure groove), and introduce high-pressure oil from the oil pool to provide power for the back of the slide vane, which is used to overcome the gas pressure and friction in the front and rear chambers of the slide vane head, to ensure that the compressor runs smoothly during the entire operation process. The slice head is always in contact with the inside of the cylinder. [0003] The oil under the back pressure of ...
