摘要 |
A seal for high pressure, large diameter applications wherein three factors, each individually known in the prior art, are combined to provide a seal which is capable of operating in such applications. These factors are (1) a ratio of face width to the inner radius of the face in the range of 0.085 to 0.30; (2) hydrodynamic lift-off pads; and (3) controlled negative rotation of the sealing rings.
