摘要： A gas-path leakage seal for generally sealing a gas-path leakage-gap between spaced-apart first and second members of a gas turbine (such as first and second segments of a gas turbine combustor casing). The seal includes a generally imperforate foil-layer assemblage which is generally impervious to gas, is located in the leakage-gap, is spaced apart from the first member, and has a first foil layer. The seal also includes a cloth-layer assemblage contacting the first member and having a first cloth layer generally enclosing and generally enclosingly-contacting the foil-layer assemblage. The first foil layer is made from a metal, ceramic, and/or polymer. The first cloth layer is made from metal, ceramic, and/or polymer fibers. The foil assemblage provides for sealing and flexibility, and the cloth assemblage provides for wear resistance and flexibility. The seal accommodates different surface shapes, assembly misalignment, vibration, and differential thermal growth of the gas turbine members.

摘要： A method for making a brush seal includes weaving a single-layer bristle assemblage having two spaced-apart cloth segments joined together by an unwoven section wherein the two cloth segments and the unwoven section share a common first group of warp bristles and wherein the two cloth segments have different groups of weft bristles. The method further includes the step of cutting generally across the unwoven section of the first group of bristles to create free ends. The brush seal so made is useful, for example, to generally seal a leakage gap in a gas path of a gas turbine.

摘要： A number of sealing segments 20 mounts a brush seal about a rotor. The tips of the brush seal 46 are maintained out of contact with the rotor surface throughout the entire operating range of the turbomachinery. Thus, the increase in temperature resultant from rubs between the bristle tips and the rotor 12 which effectively increase vibrations of the turbomachinery are eliminated. Brush seals are therefore maintained out of contact with the rotor throughout the entire operating range of the turbomachinery and thus do not affect the dynamic behavior of the rotor.
摘要翻译： 许多密封段20围绕转子安装刷子密封件。 在涡轮机械的整个工作范围内，刷密封件46的顶端保持与转子表面不接触。 因此，消除了由刷毛尖端和转子12之间摩擦产生的温度的升高，其有效地增加了涡轮机械的振动。 因此，刷子密封件在涡轮机械的整个操作范围内与转子保持不接触，因此不影响转子的动态特性。

摘要： Circumferentially extending sealing segments (45) are disposed about a rotary component (16) and have seal face (34) carrying a plurality of labyrinth seal teeth (36) and a brush seal (37). The segments are movable between large and small clearance positions relative to the rotor at start-up and steady-state operating conditions, respectively. In one form, springs (31) bias the segments radially outwardly at start-up and steam pressure displaces the segments to the small clearance positions at steady-state operations. In a further embodiment, springs bias the segment for movement to the small clearance position, the extent of movement being determined by thermal expansion of centering rings mounting the segments to the stationary components.

摘要： A brush seal segment useful, when circumferentially arrayed with other such segments, to seal the gap between a rotor and a surrounding casing of a rotary machine such as a steam turbine. An annular backing plate has a rim radially-inwardly bounding together upstream-facing and downstream-facing surfaces. Canted bristles abut the upstream-facing surface. The rim is designed to allow the bristles to recover from a rotor rub. In one design, the rim acts as a labyrinth-seal tooth and is shaped to deform, under a radial force, longitudinally away from the upstream-facing surface. In another design, the rim has a more-inwardly projecting second portion near a radially-aligned edge, and only this second portion acts as a labyrinth-seal tooth.

摘要： A method for making a brush-tooth seal, such as a brush-tooth seal which is attachable to a turbine stator, includes obtaining a seal carrier having a groove and having seal teeth and obtaining a brush seal having bristles with tips. The brush seal is engaged in the groove and then attached to the seal carrier. Then, the tips of the bristles of the attached and engaged brush seal are cut, such as with an electric discharge machining (EDM) wire, at a predetermined distance from the longitudinal axis of the seal carrier.

摘要： A method for overhauling a steam turbine to increase its power without increasing its overall length. Existing seal assemblies containing seals other than brush seals are replaced with longitudinally-shorter replacement seal assemblies having only brush seals. An existing turbine section, such as a high-pressure turbine section, is replaced with a longitudinally-longer replacement turbine section having additional stages (i.e., additional rows of rotating buckets or blades).

摘要： A turbine brush seal protection device includes an annular substrate having an outer periphery and defining a slot open at the outer periphery. The slot is for receiving a portion of an annular brush seal of a gas turbine subassembly during installation of a gas turbine and such that the annular substrate at least partially covers the annular brush seal of the gas turbine subassembly. The annular substrate at the outer periphery and within the slot thereof is removably mounted to a stationary portion of the gas turbine subassembly. A turbine brush seal protection method includes the steps of providing the annular substrate, placing the annular substrate over a portion of an annular brush seal of a gas turbine subassembly such that the seal portion is inside the slot of the annular substrate during installation of a gas turbine and the annular substrate at least partially covers the annular brush seal of the gas turbine subassembly, mounting the annular substrate at the outer periphery and within the slot thereof to a stationary portion of the gas turbine subassembly, and removing the annular substrate from the stationary portion of the gas turbine subassembly before completion of installation of the gas turbine subassembly.

摘要： Bucket covers for the buckets of a rotating component of a turbomachine are in radial opposition to a stationary component containing a circumferentially extending brush seal having bristles extending into engagement with sealing surfaces of the covers as the covers rotate by the bristles. The leading edges of the covers for the buckets in the plane of rotation and in the plane containing the brush seal have ramps or rounded surfaces which minimize the wear on the bristles and degradation of the performance of the seal as the bucket covers are rotated past the brush seal.

摘要： A brush seal is comprised of arcuate seal segments having ends cut in a radial direction with bristles “canted” at an approximate 45° angle relative to radii of the segments, leaving triangular regions adjacent one end of each segment devoid of bristles at the segment interfaces. The brush seals are retrofit into conventional labyrinth seals with the backing plate for the bristles comprising a labyrinth tooth profile extending fully 360° about the seal, including those areas where bristles are not present. The sealing capacity is not substantially degraded, while affording significant sealing improvements over conventional labyrinth seals. Additionally, when retrofit into labyrinth seals with radial movement, the individual labyrinth seal segments are free to move radially independently of one another during transients.
