Abstract

The invention provides a pump body assembly and a compressor provided with the same. The pump body assembly comprises two structural parts, a bearing-type cylinder which is arranged between the two structural parts and comprises an outer ring and an inner ring which can rotate relative to the outer ring and at least one anti-attrition structure, wherein the anti-attrition structure is arranged between at least one structural part and the bearing-type cylinder to prevent the contact friction between the inner ring and the structural parts. By means of the pump body assembly provided by the invention, the problems that in the prior art, an inner ring of a pump body assembly is easy to wear and the reliability of the pump body assembly is reduced are effectively solved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a pump body assembly and a compressor having the same. Background technique [0002] The suction and exhaust structures of the traditional rotary vane compressor are arranged on the side of the cylinder, but due to the serious wear of the head of the sliding vane and the inner wall of the cylinder, the mechanical power consumption of the compressor is relatively large, and the overall energy efficiency is poor. Cause reliability problems such as abnormal wear. [0003] In the prior art, in order to solve the above problems, rolling elements and inner rings (similar to rollers) are added to the inner wall of the cylinder to form a bearing type cylinder, so that the sliding motion between the head of the slide plate and the inner wall of the inner ring is converted into inner ring and rolling motion. The rolling motion between the pump bodies reduces the mechanical power consu...
