摘要:

The analysis and design of a 50-mm diameter floating-ring helium buffer seal are described. The seal rings incorporated Rayleigh-step lift pads to provide hydrodynamic forces to separate the rings from the shaft. Maximum surface speed is 183 mls (600 fps) and maximum buffer gas pressure is 1389 kPa (200 psia).
