Gas seal assembly for cryogenic liquid turbomachines |
| 摘要 |
A dry seal apparatus (30) for a machine (10) includes a seal having a stationary portion (40) and a rotating portion (38); a space (44) disposed between the stationary and rotating portions; a biasing member (42) disposed proximate the stationary portion (40) and in contact therewith for applying a force to the stationary portion; and a labyrinth (37) proximate the rotating portion (38) and constructed and arranged for receiving a liquid for being vaporized before entering the space between the stationary and rotating portions of the seal. A related method is also provided. |

1. A turbomachine for cryogenic liquid having a dry seal apparatus, comprising:
a seal having a stationary portion (40) and a rotating portion (38); a space (44) disposed between the stationary and rotating portions; a biasing member (42) disposed proximate the stationary portion (40) and in contact therewith for applying a force to the stationary portion (40); and a labyrinth ring (37) comprising a cavity axially extended about a pump shaft (34) proximate the rotating portion (38) and constructed and arranged for receiving a liquid for being vaporized before entering the space (44) between the stationary and rotating portions of the seal. |
