Abstract

The invention discloses a magnetic suspension centrifugal compressor. The compressor comprises a centrifugal compressor body and a permanent magnet synchronous direct current motor, wherein a protective shell is arranged on the outer side of the centrifugal compressor body, the permanent magnet synchronous direct current motor is located on the side surface of the centrifugal compressor body, upper magnets are arranged on the bottom surface of the centrifugal compressor body and the bottom surface of the permanent magnet synchronous direct current motor, a fixed magnet is arranged above the inner side of a mounting base, a fixed plate is arranged on the side surface of the permanent magnet synchronous direct current motor, a limiting convex block is arranged on the outer side of the fixedplate, a movable groove is formed in the inner side of the protective shell, a movable supporting block is arranged inside the movable groove, and a supporting spring is connected to the rear end of the movable supporting block. The magnetic suspension centrifugal compressor is provided with the fixed magnet for carrying out shake-proof support on the compressor,and the limiting convex block and the movable supporting block are used in a matched mode for elastic limiting and supporting, so that the effective damping protection effect can be achieved for the compressor.

Description

technical field [0001] The invention relates to the related technical field of compressors, in particular to a magnetic levitation centrifugal compressor. Background technique [0002] The magnetic levitation centrifugal compressor is the core component of the magnetic levitation refrigeration equipment. It mainly uses the cooperation of the permanent magnet and the electromagnet to keep the compressor motor bearing in the magnetic levitation state, so that the device can run without wear and tear, effectively extending the service life of the device . [0003] However, the existing magnetic levitation centrifugal compressor lacks certain sound insulation and shock absorption measures during use. During the use of the device, it is easily affected by internal and external vibrations, which is not conducive to the normal use of the device. Most of the spring shock absorption structures It takes up a lot of space, affects the compactness of the overall structure of the device...
