摘要： A circumferentially extending brush seal positioned between static and rotary components of a machine and, during operation of the machine, the brush seal having a higher pressure region at an upstream side and a lower pressure region at a downstream side. The brush seal may include a plurality of bristles forming a bristle pack carried by the static component and cantilevered toward the rotary component such that tips of at least some of the bristles engage the rotary component. The brush seal further may include a pressure plate and a bristle pack backing plate. The bristle backing plate may include a plurality of radially extending and circumferentially spaced slots opening through opposite sides thereof. The slots may be disposed on an inner radial edge and an outer radial edge of the bristle backing plate.

摘要： A rotor of a turbomachine includes a rotor drum located at a central axis and a plurality of buckets secured to the rotor drum. A first reaction stage includes axial entry dovetailed buckets. An axial passage for cooling flow is provided along a mating surface between the bucket dovetail and the dovetail slot in the rotor drum. Cool steam at taken between a first stage bucket and a second stage nozzle and passed through the axial passage to a low pressure sink at an upstream end of the rotor.
摘要翻译：涡轮机的转子包括位于中心轴线的转子鼓和固定到转子鼓的多个叶片。第一反应阶段包括轴向入口燕尾桶。用于冷却流动的轴向通道沿着铲斗燕尾榫和转子滚筒中的燕尾槽之间的配合表面设置。在第一级铲斗和第二级喷嘴之间取出冷却蒸汽，并将其通过轴向通道转到转子上游端的低压槽。
