Gas lift bearing and oil seal |
摘要 |
A plurality of circumferentially spaced pockets are formed in the face of a stationary carbon ring. A rotating seal ring coacts with the pockets in the carbon ring to define a gas lift bearing to thereby reduce the pressure differential and leakage across the carbon ring. Alternatively the spaced pockets can be located in the rotating seal ring.
