Abstract

The invention provides a vortex compressor sealing structure and a vortex compressor containing the same. The sealing structure comprises a shell (20), an upper cover body (10), a movable vortex disk (204), a static vortex disk (203) and a breather pipe (205); the upper cover body (10) is arranged at an upper opening of the shell (20) in a sealing mode, the movable vortex disk (204) and the static vortex disk (203) are arranged in the shell (20) and are provided with rolling plates mutually meshed and present vortex type curves, and a breather pipe (205) which penetrates through the upper cover body (10) and is arranged in the shell (20), wherein the breather pipe (205) is arranged on the upper end surface of the static vortex disk (203), and a sealing piece is arranged between the matched end surfaces of the breather pipe (205) and the static vortex disk (203). According to the sealing structure of the vortex compressor disclosed by the invention, the requirement on processing precision of the sealing structure can be reduced, the processing cost is reduced, and the installation efficiency is improved. The vortex compressor disclosed by the invention comprises the sealing structure.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a scroll compressor sealing structure and a scroll compressor including the sealing structure. Background technique [0002] A scroll compressor is a well-known compressor, and a casing of this scroll compressor houses a compression mechanism connected to a drive motor through a drive shaft. [0003] figure 1 A longitudinal sectional view of a conventional scroll compressor is shown. like figure 1 As shown, the above-mentioned scroll compressor includes a longitudinally long cylindrical shell 20', a bowl-shaped upper cover 10' and a lower cover 12' fixed to close the openings at both ends of the shell, and the shell 20' The above-mentioned compression mechanism is installed on it. [0004] As is well known, a scroll compression mechanism used in a scroll compressor includes an orbiting scroll 204' and a fixed scroll 203' having wraps formed in a scroll-shaped curve such that the re...
