AI Technical Summary

Problems solved by technology

Therefore, considerable friction is generated between the sealing member and the disk surface of the scroll 7a, which not only hinders the rotational movement of the movable scroll 7a, but also wears the disk surface, shortening its life.

Abstract

The leakage-proofing device of cooling agent in vortex portion of vortex compressor is characterized by that the compressor is fixed ont he vortex, disk, and the projected vortex sheet is set, its movable vortex disk is equipped with projected vortex sheet, the movable vortex disk is fixed on the driving shaft, the vortex sheets are mutually bite-connected, and the compression chamber with high-pressure portion, medium-pressure portion and low-pressure portion is formed from rotated central portion to outward direction, the vortex-like groove guide device is mounted on the tail end of vortex sheet, and the vortex-like sealing member of sealed comperssion chamber is inserted into groove guide device, and then sealing member can be fixed.

Description

technical field [0001] The invention belongs to scroll compressors, in particular to a coolant leakage prevention device for scroll parts of scroll compressors. Background technique [0002] Generally speaking, a scroll compressor is a compressor that compresses the coolant by changing the volume of the compression chamber formed by a pair of opposing scrolls, such as figure 1 As shown, it mainly includes the following components: sealed box 1, which is arranged in the sealed box and divides its internal space into the discharge chamber 2 and the suction chamber 3. The boundary film 4, the bottom surface of the boundary film has a protrusion to form a fixed scroll piece 7a The fixed scroll 5, the movable scroll 6 which protrudes into the movable scroll 7b and the motor 8 of the fixed movable scroll that engages with the scroll of the fixed scroll. [0003] The scroll compressor described above operates as follows: [0004] When the scroll compressor is energized, an induce...
