摘要： Brush seals are retrofitted into existing turbine labyrinth seal rings to create a fail-safe seal design at locations wherever labyrinth seals are currently used, including interstage shaft seals, rotor end seals, bucket (or blade) tip seals and spill strips. Brush seals, per se, when used in place of labyrinth seals, can result in considerable span reductions of steam turbines, or machines with more turbine stages for a given span. Application to end packings results in the potential elimination of gland sealing/exhauster systems. Brush seal life can be improved by retrofitting brush segments to labyrinth seal segments that are either spring-backed, or use pressure loads to obtain design clearances only after steady state operating conditions are achieved. The brush seals are provided with backing plates shaped like labyrinth teeth, resulting in a fail-safe design. Also, the use of existing labyrinth teeth as bristle backing plates results in a brush seal with diminished susceptibility to hysteresis when compared to conventional brush seal designs. Low friction coatings can also be used to reduce brush seal hysteresis. Incorporation of brush seals in labyrinth seal rings that are either spring-backed or held in place by pressure forces results in extremely low brush seal wear.
摘要翻译：电刷密封件改装成现有的涡轮迷宫式密封环，以在目前使用迷宫式密封件的位置创建故障安全密封设计，包括级间轴密封件，转子端部密封件，铲斗（或刀片）末端密封件和溢出条。刷子密封件本身在用于代替迷宫式密封件时，可以导致蒸汽轮机或具有更多涡轮级的机器在给定跨度上的相当大的跨度减少。对端部密封的应用导致密封/排气系统的潜在消除。刷子密封寿命可以通过将刷段改装为弹簧密封段，或者使用压力负载仅在达到稳态工作条件之后才能获得设计间隙。刷子密封件设置有类似迷宫齿的背板，从而形成故障安全设计。此外，与传统的刷密封设计相比，使用现有的迷宫齿作为刷毛背板导致刷密封，对滞后的敏感性降低。低摩擦涂层也可用于减少刷子密封滞后。将刷子密封件装入迷宫式密封环中，弹簧支撑或通过压力力保持在适当位置导致极低的刷密封磨损。

摘要： A brush seal assembly is radially and axially repositionable relative to stationary and rotating components. Shim packs whose thickness can be reduced by peeling adhesively attached foil layers from the shim packs are used to provide both axial and radial repositioning. In another form, a plurality of set screws may be threaded into a mounting member for the brush seal assembly to controllably space the brush seal from the rotating component. In a further form, an eccentric cam is rotated to reposition the brush seal assembly radially inwardly or outwardly with shim packs being used to reposition the brush seal in an axial direction.

摘要： The positions of brush seal segments are positively adjusted relative to a housing carrying the brush seal segments and the opposing sealing component by employing members formed of thermally responsive material. The members are heated by heating elements receiving controlled power. By increasing or decreasing the power provided to the heating elements, the members are expanded or contracted to move the brush seal segments toward or away from the opposing sealing component.

摘要： A brush seal is provided between a first stationary component and a second rotating component. A cooling medium is provided through a plurality of jet nozzles for flow along an upstream surface portion of the brush seal bristles and along the rotating component surface adjoining the tips of the bristles. The cooling medium cools the brush seal bristles to a temperature below the temperature of the working fluid passing through the turbine. The jet nozzles may be arranged in the shroud or in the upstream backing plate of the brush seal to direct the cooling medium toward the juncture of the brush seal and the sealing surface.

摘要： A brush seal segment is mounted within a pressure vessel and against an arcuate surface of an element to provide a seal between regions on opposite sides of the seal at different pressures. By vibrating the vessel through a range of frequencies, natural frequencies of the brush seal under pressure loading can be ascertained. Additionally, by adjusting interference between the arcuate surface and the bristle tips, natural frequencies of the brush seal under various interference loadings can likewise be ascertained. The pressure vessel has mounts for attaching the vessel to a shaker table to facilitate vibrating the vessel through the range of frequencies.

摘要： A rotary machine includes a rotatable rotor, blades radially mounted on and spaced apart about the rotor, a stationary casing disposed about and radially outward from the rotor and blades defining an annular gap between the casing and tips of the blades, and a flexible abradable seal assembly attached on the casing and disposed within the annular gap such that during differential growth of the rotor and blades relative to the casing the seal assembly flexes and abrades in response to contact by the blade tips and thereby clearance between the casing and blade tips is controlled as to avoid contact by the moving blade tips with the casing.
