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.
摘要翻译：当用其它这种部分周向排列时，用于密封旋转机器（例如蒸汽轮机）的转子和周围壳体之间的间隙的刷密封段是有用的。环形背板具有径向向内限定在一起的面向上游和下游的表面的边缘。鬃毛紧靠着面向上游的表面。轮辋旨在使刷毛从转子摩擦中恢复。在一种设计中，轮辋用作迷宫式密封齿并且成形为在径向力作用下纵向远离上游侧表面变形。在另一种设计中，轮辋在径向对齐的边缘附近具有更向内突出的第二部分，并且仅该第二部分用作迷宫式密封齿。

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： A steam turbine having a shaft and a first (e.g., high-pressure) turbine section. A first embodiment also includes a first bearing longitudinally spaced apart from the first turbine section and further includes a first brush-seal assembly, having bristles, longitudinally positioned between the first turbine section and the first bearing and radially positioned proximate the shaft. The steam turbine is devoid of any backup seal to the bristles. In a second embodiment, a second brush seal assembly is positioned between the first and second (e.g., intermediate-pressure) turbine sections which lack any intervening bearing.

摘要： A self-centering brush seal is disposed in an annular groove formed in a stationary component about a rotatable component, the stationary and rotatable components having a common axis. The brush seal includes a plurality of bristles projecting into sealing engagement with the rotating component. The brush seal has a radial clearance in the groove enabling the brush seal for free-floating radial excursions within the groove to maintain concentricity with the rotary component notwithstanding deviation of the axis of rotation of the rotating component relative to the axis of the fixed component. In another form, the brush seal comprises a plurality of arcuate segments having a helical coil spring biasing the segments for radial movement enabling the tips of the bristles to seal against the rotatable component. In a further embodiment, leaf springs bias each segment to maintain its bristles in engagement with the rotatable component. In a still further embodiment, the seal segments are pressure balanced in a radial direction with an O-ring seal sealing high and low pressure regions on opposite sides of the segments.

摘要： A seal assembly and a rotary machine, such as a steam turbine, containing the seal assembly. A casing circumferentially surrounds a rotor and includes a circumferential channel open to the rotor. Seal segments are circumferentially arrayed in the channel and are movable between radially inward and outward positions. Circumferentially adjacent seal segments have circumferentially opposing surface grooves. A resilient and imperforate member is engaged in the grooves of circumferentially-adjacent seal segments circumferentially urging apart such segments and providing sealing between such segments.

摘要： A seal assembly and a rotary machine, such as a steam turbine, containing such seal. A stator circumferentially surrounds a row of rotor blades. The stator includes an upstream tooth-seal region, a downstream brush-seal region, and an intervening fluid expansion chamber all radially near the blade tips. Debris in the fluid stream is broken down into smaller particles by the tooth-seal region, and the smaller particles are slowed down by the fluid expansion chamber such that minimal damage is caused to the downstream bristles in the brush seal region.

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。
