Title:
PUMP BODY AND SLIDING-VANE COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2020/052128
Kind Code:
A1
Abstract:
Disclosed are a pump body and a sliding-vane compressor. The pump body comprises: an air cylinder assembly (10), the air cylinder assembly (10) comprising a cylinder body (11) and a rotary bearing cylinder (12) rotationally arranged therein; an upper flange (20) and a lower flange (30); the upper flange (20) and the lower flange (30) being respectively arranged at two end faces of the air cylinder assembly (11); and the end faces of the rotary bearing cylinder(12) being respectively in rolling contact with the upper flange (20) and the lower flange (30). As the end faces of the rotary bearing cylinder (12) are respectively in rolling contact with the upper flange (20) and the lower flange (30), the problem of friction abrasion of the end faces of the rotary bearing cylinder (12) can be effectively relieved in the actual working process, thereby prolonging the service life of the rotary bearing cylinder (12)and improving the reliability of the compressor.
