COMPRESSOR AND REFRIGERATION SYSTEM

WIPO Patent Application WO/2023/087731

A1

Provided is a compressor, comprising: a rotor (110), comprising a middle shaft body (111) and two end shaft bodies (112), wherein the two end shaft bodies (112) are respectively arranged at two ends of the middle shaft body (111) and the diameter of each end shaft body (112) is less than the diameter of the intermediate shaft body (111); and an adjustment assembly which comprises an axial adjustment portion, the axial adjustment portion comprising two axial air bearings (200). The two axial air bearings (200) are respectively sleeved on the two end shaft bodies (112) and are respectively close to two ends of the middle shaft body (111). The two axial air bearings (200) are used for counteracting the axial offset of the rotor (110). The two axial air bearings (200) are respectively sleeved on the two end shaft bodies (112) to counteract the axial offset of the rotor (110). There is no need to provide a thrust disc on the shaft body of the rotor (110), thereby lowering the load of the rotor (110), reducing the length of the rotor (110), and effectively increasing the critical speed of the rotor (110).
