| 摘要 |
A thrust control system for use with a turbocompressor having gas bearings in which the average static pressure in the compressor housing differs substantially from the average static pressure in the expander housing which, during operation of the turbocompressor, will reduce the net resulting thrust to nearly zero without compromising the performance of the turbocompressor. In one embodiment of the invention, the thrust control system includes a pair of gas-dynamic thrust bearings and one compensation chamber with prescribed area and pressure ratios such that under static conditions the equilibrium position of the rotating assembly portion of the turbocompressor is in the center of the axial clearance range and under dynamic conditions the maximum displacement from center does not exceed the existing clearance.
