Abstract

The invention provides a double-stage compressor. The double-stage compressor comprises a housing, a vortex assembly, a rotor assembly, a crank shaft and a bracket part. The housing is provided with an inner cavity; the vortex assembly is arranged in the inner cavity of the housing; the rotor assembly is arranged in the inner cavity of the housing; the crank shaft is connected with the vortex assembly and the rotor assembly in a driving manner; the bracket part is fixedly connected to the housing and arranged between the vortex assembly and the rotor assembly; a supporting piece is arranged at a first side of the bracket part; an air cylinder is formed at a second side of the bracket part; the vortex assembly is arranged on a position, which is coaxial to the air cylinder, on the bracket part by the supporting piece; the rotor assembly is coaxially arranged in the air cylinder; and a through hole for penetrating the crank shaft is further formed in the bracket part. The double-stage compressor disclosed by the invention can be used for effectively solving a problem that the double-stage compressor in the prior art has high difficulty in assembling process.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a two-stage compressor. Background technique [0002] In the existing technology, the two-stage compressor that uses the rotor assembly for the first stage compression and the scroll assembly for the second stage compression has its advantages in efficiency, but it is difficult to ensure the coaxiality of the two assemblies during assembly, which makes the assembly process difficult High, increasing production and assembly costs. Contents of the invention [0003] The present invention aims to provide a two-stage compressor to solve the problem of high difficulty in the assembly process of the two-stage compressor in the prior art. [0004] In order to achieve the above object, according to one aspect of the present invention, a two-stage compressor is provided, comprising: a housing with an inner chamber; a scroll assembly disposed in the inner chamber of the housing; a r...
