旋转机械抽吸密封组件及其装配方法
摘要：
本发明涉及旋转机械抽吸密封组件及其装配方法。一种用于与旋转机械一起使用的抽吸面密封件包括旋转密封环，该旋转密封环包括径向外表面，该径向外表面包括倾斜部分。固定密封环紧接旋转密封环联接，使得第一间隙限定在它们之间。固定密封环能够在打开位置与密封位置之间沿着旋转机械的中心线轴线移动，并且包括延伸跨过第一间隙的延伸部件。辅助密封件包括至少一个密封齿，该至少一个密封齿包括密封齿顶端。该至少一个密封齿从延伸部件径向向内延伸，使得第二间隙限定在密封齿顶端与倾斜部分之间。
摘要（英）：

The invention relates to a rotary machine aspirating seal assembly and a method of assembling the same. An aspirating face seal for use with a rotary machine includes a rotating seal ring including a radially outer surface that includes an oblique portion. A stationary seal ring is coupled proximate the rotating seal ring such that a first gap is defined therebetween. The stationary seal ring is movable along a centerline axis of the rotary machine between an open position and a sealed position, and includes an extension member that extends across the first gap. An auxiliary seal includes at least one seal tooth that includes a seal tooth tip. The at least one seal tooth extends radially inward from the extension member such that a second gap is defined between the seal tooth tip and the oblique portion.
