Pump components, compressors and air conditioners

Abstract

The application provides a pump body assembly, a compressor and an air conditioner. The pump body assembly includes a main shaft, a flange, a cylinder, and a sliding vane. The main shaft includes a convex portion, and a plurality of sliding vanes are arranged on the convex portion at intervals along the circumferential direction. Corresponding to each compression cavity, there is at least one radial exhaust channel, and an axial exhaust channel is also opened on the main shaft, and the axial exhaust channel extends along the axial direction of the main shaft to the outside of the matching area between the flange and the main shaft. And it communicates with the space outside the pump body assembly. An exhaust valve assembly is arranged in the radial exhaust passage. The exhaust valve assembly communicates with the compression chamber and the axial exhaust passage when the pressure of the refrigerant in the compression chamber reaches a preset pressure. According to the pump body assembly of the present application, the area of ​​the exhaust passage can be unrestricted, and at the same time, leakage during the compression process of the compressor can be effectively avoided to ensure the performance 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 prior art, the sliding vane compressor generally adopts the side exhaust method of the cylinder to exhaust, but the side exhaust of the cylinder will cause the phenomenon of gas crossing between the front and rear vanes near the exhaust port, which will increase the leakage of the compressor. The traditional exhaust valve is a reed valve, and the resistance is very large when the valve is opened. Since the pump body of the compressor is soaked in refrigerated oil, the exhaust channel of the side row of the cylinder is also surrounded by refrigerated oil. During the exhaust process, The presence of refrigerated oil will increase the opening force of the valve plate, which will further increase the power consumption of the compressor. [0003] In order to solve the ab...

Problems solved by technology

[0004] But at the same time, the problem is that the minimum distance of the axial exhaust channel along the width direction of the slide must be smaller than the width of the slide, otherwise it will cause air leakage between the front and rear chambers, resulting in leakage and affecting the cooling capacity. The area of ​​the exhaust channel will lead to the area of ​​the exhaust channel being too small, the exhaust velocity will increase, the exhaust loss will increase, and the power consumption will increase.
