Title: COMPRESSOR SYSTEM PROVIDED WITH GAS BEARING, AND METHOD FOR SUPPLYING GAS TO COMPRESSOR PROVIDED WITH GAS BEARING
Abstract:
The present invention pertains to gas supply to a gas bearing of a compressor, and provides a compressor system which is usable for a long period of time while suppressing device costs and is capable of improving reliability, and a gas supplying method. A compressor system 1 has: compression parts 101, 102 that suck in and compress a gas; a rotor 11 provided with the compression parts 101, 102; gas bearings 2A-2C that support the rotor 11; dynamic pressure generation lines 31A-31C that supply a gas extracted from the gas pressurized by the compression part 101 to the gas bearings 2A-2C; and a static pressure external gas supply system 4 that supplies an external gas from the outside of the compression part 101 to the gas bearings 2A-2C.
