Abstract

The invention discloses a centrifugal compressor and a refrigerant circulating system. The centrifugal compressor comprises a shell with an accommodating cavity, a main shaft rotatably arranged in theaccommodating cavity, a diffuser, gas thrust bearings and a gas-supply flow channel, and the gas-supply flow channel comprises a diffuser gas-supply flow channel formed in the diffuser and used for supplying gas to the gas thrust bearings. According to the centrifugal compressor, the diffuser gas-supply flow channel is formed in the diffuser so as to directly supply the gas to the gas thrust bearings, the structure is simple, and machining is convenient.

Description

technical field [0001] The invention relates to the technical field of static pressure gas bearings, in particular to a centrifugal compressor with a diffuser air supply channel and a refrigerant circulation system. Background technique [0002] Due to the advantages of high precision, low friction, low vibration, low noise, long life and no pollution, gas static pressure bearings are widely used in centrifugal compressors. Gas hydrostatic bearings use external pressure to form a gas film for gas lubrication, and their bearing capacity and stiffness increase with the increase of gas supply pressure. However, the disadvantage of gas static pressure bearings is that there is a phenomenon of "air hammer vibration". The internal pressure of the bearing can be changed, the higher the internal pressure, the more serious the vibration of the air hammer. Contents of the invention [0003] The object of the present invention is to provide a centrifugal compressor and a refrigeran...
