    摘要： A rotary machine includes a rotatable rotor, buckets radially mounted on and spaced apart about the rotor, a stationary stator/casing disposed about and radially outward from the rotor defining an annular gap between the casing and tips of the buckets, and an abradable seal member provided to the bucket tip portions and disposed within the annular gap such that during differential growth of the rotor and buckets relative to the casing the seal member abrades in response to contact with a base seal member provided to the stator casing. Thereby, clearance between the stator casing and bucket tips is minimized between the moving bucket tips with the stator casing.

    摘要翻译： 旋转机械包括可转动的转子，围绕转子径向安装并间隔开的转子;固定的定子/壳体，其从转子周围和径向向外设置，限定了壳体和叶片尖端之间的环形间隙，以及可磨损的密封构件 提供到铲斗前端部分并且设置在环形间隙内，使得在转子和铲斗相对于壳体的差速生长期间，密封件响应于与设置到定子壳体的基座密封构件的接触而磨损。 因此，在具有定子壳体的移动的铲斗前端之间，定子壳体和铲斗前端之间的间隙最小化。

    摘要： A shaft seal reduces leakage between a rotating shaft such as a rotor and a stator. The shaft seal or shingle seal includes a plurality of compliant-plate members attached to the stator in facing relation. The compliant-plate members define a sealing ring between the stator and the rotating shaft. Each of the compliant-plate members includes a plurality of shingles, where adjacent compliant-plate members are disposed relative to each other such that the shingles are at least partially staggered in a direction of axial leakage.

    摘要： The seal between high and low pressure regions in a turbine or turbo-machinery includes arcuate segments having a brush seal flanked on one or both sides by a plurality of beams lying adjacent to and in contact with one another. Shims separate the bristles of the brush seal from the rows of beams. The cross sectional dimension of the beams is 20-60 times the diameter of the bristles. The beams terminate short of the rotary component while the bristle tips engage the rotary component. The beams take up most of the pressure difference while the bristles take up the balance of the pressure difference across the seal.

    摘要翻译： 涡轮或涡轮机械中的高压区域和低压区域之间的密封件包括弧形段，其具有在一侧或两侧上由彼此相邻并相互接触的多个梁侧面的刷子密封。 垫片将刷子密封件的刷毛与梁排分开。 梁的横截面尺寸是刷毛直径的20-60倍。 当刷毛尖端接合旋转部件时，光束终止于旋转部件的较短处。 光束占据大部分压力差，而刷毛占据了密封件两端的压力差的平衡。
