Abstract

The invention relates to the technical field of gas bearings, and discloses a gas supply adjustable bearing. The bearing comprises a rear bearing disc (1) and a front bearing disc (2), wherein arc-shaped hole grooves (11) are distributed in the surface of the rear bearing disc (1); a plurality of through holes (21) are formed in the surface of the front bearing disc (2), and in different states, the through holes (21) with different numbers are formed corresponding to the arc-shaped hole grooves (11). In the initial stage of starting of the compressor, the through hole (21) corresponding to the arc-shaped hole groove (11) is opened by a small section, and refrigerant loss is reduced. As the rotating speed of the bearing is increased and the requirement for supporting force is increased, the through holes (21) accounting for half of the number of the through holes (21) and the through holes (21) accounting for three quarters of the number of the through holes (21) are gradually opened, under the conditions of external fluctuation and unstable operation, all the through holes (21) are opened, stability is improved, and the purpose of saving air supplied by the bearing is achieved. The invention further discloses an air suspension compressor.

Description

technical field [0001] The present application relates to the technical field of gas bearings, for example, a bearing with adjustable gas supply and a gas suspension compressor. Background technique [0002] Air-suspension compressors have become one of the mainstream directions for the development of centrifugal compressors due to their high efficiency, energy saving, and oil-free characteristics. The bearings of air-suspension compressors are a key part of ensuring the normal operation of air-suspension compressors. Air suspension compressor bearings are divided into radial bearings and axial bearings. The clearance of the axial bearing is 5 to 10 times that of the radial bearing, and the air consumption of the axial bearing accounts for more than 80% of the overall air consumption. [0003] In the early stage of compressor operation, the impeller speed is low, the axial force of the rotor shaft is small, the axial bearing fails to function, and a large amount of air suppl...
