Abstract

The invention provides a compressor pump body, a compressor and an air conditioner. The compressor pump body comprises a main shaft, an air cylinder, an upper flange and an air pull structure. A center portion is arranged on the main shaft, and sliding piece grooves and a lubricating oil conveying channel are formed in the center portion. The air cylinder sleeves the periphery of the center portion. The upper flange sleeves the main shaft and is located on the upper end face of the air cylinder, a first back pressure groove which communicates with the sliding piece grooves is formed in the upper flange, and the conveying channel communicates with the first back pressure groove. The air pull structure is arranged on the upper flange to exhaust the gas in the first back pressure groove to the exterior of the compressor pump body. By the adoption of the compressor pump body, the situation that the oil level of lubricating oil is lower than the upper surfaces of sliding pieces can be avoided, the states that the back pressure of each sliding piece is stable, and the fluctuation is low can be guaranteed, and the operating reliability of the compressor pump body and the compressor with the compressor pump body can be improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a compressor pump body, a compressor and an air conditioner. Background technique [0002] During the operation of the rotary vane compressor, the sliding vane gradually protrudes under the action of back pressure and centrifugal force, and clings to the inner wall of the cylinder. It is also a periodic change that first increases and then decreases. When there are multiple slides, at the same time, some slides protrude and some slides retreat, the volume change range of the tail cavity of the slides will be smaller than that of a single slide, but there are still fluctuations. figure 1 Shown is the volume change curve of the tail cavity of the three-slider structure. [0003] Since the initial oil level in the compressor housing is generally below the upper end surface of the cylinder (or the large end surface of the upper flange), when the compressor is not running, ...
