AI Technical Summary

Problems solved by technology

Both the Oldham slip ring 3 and the upper bracket 4 have machining errors, that is, the maximum machining error of the width L of the oil passage gap is the superposition of the machining errors of the Oldham slip ring 3 and the upper bracket 4, resulting in a large error in the width L of the oil passage gap , which makes the processing of the pump body components in the compressor difficult and the precision is not high, and it is impossible to accurately control the amount of lubricating oil

Abstract

The invention discloses a scroll compressor and a pump body assembly thereof. The pump body assembly includes a movable scroll (2) and an upper bracket (4) for supporting the movable scroll (2). The bracket (4) is provided with an annular sealing groove (4b); the side of the upper bracket (4) facing the movable scroll (2) has a sealing seal connected to the outer wall of the sealing groove (4b). The groove step surface (4e) and the moving disk supporting surface (4f) for contacting the movable scroll (2), the gap between the moving disk supporting surface (4f) and the sealing groove stepped surface (4e) There is a height difference L; the sealing groove step surface (4e) is lower than the moving disk support surface (4f). The pump body assembly provided by the invention effectively improves the processing accuracy, reduces the processing difficulty, and facilitates the precise dosage of lubricating oil.

Description

technical field [0001] The invention relates to the technical field of compressor equipment, in particular to a scroll compressor and a pump body assembly thereof. Background technique [0002] The scroll compressor is a kind of volumetric compression compressor, and the compression part is composed of a moving scroll and a fixed scroll. [0003] Please refer to figure 1 , figure 2 and image 3 , figure 1 It is a structural schematic diagram of a scroll compressor in the prior art; figure 2 It is a structural schematic diagram of a pump body assembly in the prior art image 3 for figure 2 A partial enlargement of the . [0004] The scroll compressor includes a housing 15 in which a fixed scroll 1 , a movable scroll 2 , an Oldham slip ring 3 and an upper bracket 4 are installed. The movable scroll 2 is rotatably arranged on the Oldham slip ring 3 , and there is an oil passage gap between the upper support 4 and the movable scroll 2 , and the width of the oil passag...
