STATIONARY SEAL RING FOR A CENTRIFUGAL COMPRESSOR |
摘要 |
A stationary seal ring is adapted to cooperate with a housing and an impeller to define a seal. The impeller is rotatable about an axis and includes a first seal portion and a plurality of blades that define an outside diameter. The stationary seal ring includes an alignment surface engageable with the housing, and a plurality of teeth. Each tooth is spaced axially from an adjacent tooth to define a cavity therebetween. Each tooth includes a tooth tip that cooperates with the first seal portion to define a seal point. A first tooth disposed nearest to the blades has a first tip diameter. Each subsequent tooth has a tip diameter that is smaller than the first tip diameter. |
