A scroll sealing structure, scroll compressor and air conditioner

Abstract

The present disclosure provides a scroll sealing structure, a scroll compressor and an air conditioner. The scroll sealing structure includes: a first scroll, a second scroll and a seal, and a groove is provided on the end surface of the scroll, The opening of the groove is provided with a blocking member, and the blocking member partially blocks the opening to form a gap; the sealing member includes a first sealing part and a second sealing part, the first sealing part is accommodated in the groove, and the first sealing part is The second sealing portion can be opposed to the barrier and form a seal, the second sealing portion can protrude from the notch, and the end surface of the second sealing portion can be opposed to the bottom surface of the second scroll and form a seal, or the end surface of the second sealing portion can be with the bottom surface of the second scroll. The bottom surfaces of the first scroll are opposite and form a seal. According to the present disclosure, the leakage caused by the axial gap is greatly reduced, the volumetric efficiency of the compressor is improved, the stability of the sealing strip is improved, and the problem that the sealing strip cannot be floated or can only float partially or cannot always be in close contact with the groove is solved. side wall and cause leakage problems.

Description

technical field [0001] The present disclosure relates to the technical field of compressors, in particular to a scroll sealing structure, a scroll compressor and an air conditioner. Background technique [0002] In scroll compressors, the gas leakage between the scrolls will greatly reduce the volumetric efficiency of the machine, and this internal leakage is mainly divided into tangential leakage through the radial gap and radial leakage through the axial gap. Since the leakage line length of the axial gap is much larger than that of the radial gap, preventing the radial leakage through the axial gap plays an important role in improving the performance of the whole machine. Now the more mainstream axial sealing method is to open a sealing groove on the end face of the scroll gear, the sealing strip is installed in the sealing groove, and the gas enters the space between the bottom surfaces of the grooves, so that the sealing strip floats and passes through the raised part o...

AI Technical Summary

Problems solved by technology

[0004] Therefore, the technical problem to be solved in the present disclosure is to overcome the defects of the scroll compressor in the prior art that the sealing strip cannot float or can only float a part or cannot always stick to the side wall of the tank, resulting in leakage and poor sealing effect , thereby providing a scroll sealing structure, a scroll compressor and an air conditioner
