Self-dehumidifying hydrostatic gas bearing

A self-dehumidifying hydrostatic gas bearing, comprising:

• a bearing seat, wherein a cavity is provided inside the bearing seat and an inlet pipe is provided on an outer surface of the bearing seat and communicates with the cavity, and wherein the bearing seat defines an exhaust channel extending from the cavity to an exterior of the bearing seat;
• a rotary shaft passing through the bearing seat;
• a magnetic component that is sleeved on an outside of the rotary shaft and configured to generate a magnetic field when the rotary shaft rotates;
• and
• a throttling vaporization structure provided inside the cavity, wherein the throttling vaporization structure comprises a plurality of annular throttling elements and a plurality of annular vaporization elements interleaved with one another, wherein:
• the inlet pipe is adjacent to a first annular throttling element,
• the magnetic component is adjacent to a last annular throttling element,
• the exhaust channel includes a first gap is that is formed between the last annular throttling element and the magnetic component,
• the plurality of annular throttling elements are configured to throttle a working medium flowing through the cavity to cool the working medium,
• the plurality of annular vaporization elements are electrically conductive such that, during rotation of the rotary shaft, eddy currents are induced in the plurality of annular vaporization elements by the magnetic field generated by the magnetic component to heat and vaporize at least a liquid phase portion of a cooled working medium, and
• the exhaust channel is configured to discharge the working medium in a gas phase.
