[0124] In some embodiments, the pumping device 310 includes a compressor. The compressor can be a conventional compressor, which can effectively pressurize the gaseous refrigerant.

[0125] In some embodiments, the gas supply system further includes a filtering device (not shown in the figure), which is arranged on the pipeline at the input end of the pumping device 310. In this embodiment, the filtering device can be a filter for filtering impurities in the gaseous refrigerant.

[0126] Optionally, the filtering device adopts a cyclone centrifugal device. The cyclone centrifugal device can effectively remove solid and liquid impurities in the gaseous refrigerant. The liquid impurities refer to refrigerant droplets mixed in the gaseous refrigerant. Reducing the mixing of liquid can improve the pressurization effect of the pumping device 310 (the compressor), reduce the damage of the liquid refrigerant to the pumping device 310 and the gas bearing, and prolong the service life.

The gaseous refrigerant in the refrigeration system containing the air-suspension compressor 200 is pressurized by the pumping device 310 and directly delivered to the pressure-stabilizing chamber 110 of the air-suspension compressor 200. After pressure stabilization, the gaseous refrigerant is then delivered to the gap between the gas bearings on both sides of the air-suspension compressor 200.
