摘要： A seal assembly is provided for a rotary machine wherein the rotary machine comprises a rotor and a casing. The rotor comprises a generally longitudinally-extending axis. The casing is generally coaxially aligned with the axis. The casing circumferentially surrounds, is radially spaced apart from the rotor, and comprises an inner circumferential channel generally coaxially aligned with the rotor. The seal assembly comprises a plurality of seal carrier segments fixedly disposed in a circumferential array in the inner circumferential channel. Each of the seal carrier segments comprises a seal carrier channel. At least one of the seal carrier segments comprises at least one fluid inlet disposed therein. In addition, the seal assembly comprises a (meaning at least one) seal disposed in the seal carrier channel and is movable between radially inward and radially outward positions upon introduction of fluid medium in the fluid inlet.

摘要： A plurality of brush seal segments are disposed in a groove of a component fixed against rotation and project into sealing relation with a rotating component. The brush seal segments are each comprised of a pair of plates having a plurality of brush bristles therebetween, the plates and bristles being secured along the outer arcuate face of the segments by a weld bead. The opposite ends of the bristles form the seal with the rotary component. Each brush seal segments is disposed in a groove with generous clearance between a hook on the segment and a flange on the fixed component. A spring between the fixed component and arcuate outer face of the brush seal segment biases the segment in a radial direction. The end of the spring has a pair of tabs spaced axially from one another for reception in a pair of axially spaced recesses to retain the spring against circumferential movement while simultaneously maintaining the integrity of the weld joint without loss of securement of the bristles.

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： A gas turbine seal structure provided between end portions of a moving blade platform and a stationary blade inside shroud. The sealing performance of the seal structure is improved by increasing the resistance to the flow of air. A seal plate (21, 31) is mounted to an end portion of a platform (2, 2′) of the moving blade (1) and a seal portion is formed by seal fins (22, 32) and a honeycomb seal (16, 17) disposed on a lower surface of an end portion (12a, 12b) of an inside shroud (12) of a stationary blade (11). Sealing air from the stationary blade (11) produces a high temperature in a cavity (14) and flows into a space (18, 19), and also air leaking from the cooling air of the moving blade (1) is able to escape into a high temperature combustion gas passage through a seal portion. However, since the seal plate has three seal fins (22, 32) that are inclined in a direction so as to oppose the air flow, air resistance is increased and the flow of air into the combustion gas passage is prevented.
摘要翻译：一种燃气轮机密封结构，其设置在活动叶片平台的端部和固定叶片内部的护罩内。通过增加对空气流动的阻力来改善密封结构的密封性能。密封板（21,31）安装在活动叶片（1）的平台（2,2'）的端部，密封部分由密封翅片（22,32）和蜂窝密封件（16）形成，17），其设置在固定叶片（11）的内侧护罩（12）的端部（12a，12b）的下表面上。来自固定叶片（11）的密封空气在空腔（14）中产生高温并流入空间（18,19），并且从活动叶片（1）的冷却空气泄漏的空气也能够逸出通过密封部分的高温燃烧气体通道。然而，由于密封板具有在与空气流相对的方向上倾斜的三个密封翅片（22,32），因此空气阻力增加，并且防止了进入燃烧气体通道的空气流。

摘要： A brush seal includes a mounting ring that carries radially inwardly directed bristles. A backing member attached to the mounting ring is positioned alongside the bristles. A chamber defined by the bristles and the backing member is pressurized with fluid to counteract the lateral forces imposed upon the bristles by a region of high fluid pressure that they are operationally adjacent. As a result of this balancing of forces, the bristles are free to move radially inward and outward so that their free ends remain in sealing engagement with an adjacent surface.
摘要翻译：刷密封件包括承载径向向内指向的刷毛的安装环。附着在安装环上的背衬元件位于刷毛的旁边。由刷毛和背衬构件限定的腔室被流体加压，以抵抗施加在刷毛上的横向力通过它们在操作上相邻的高流体压力的区域。由于这种力的平衡，刷毛自由地径向向内和向外移动，使得其自由端保持与相邻表面的密封接合。

摘要： A face seal assembly is provided having an annular seal body mounted in an axially moveable relationship to a seal support structure. A piston ring is disposed between the annular seal body and the seal support structure forming a secondary seal. A first locator spring, which is an annular wave spring, is disposed between said seal support structure and the piston ring to urge the piston ring in an axial direction. Optionally, a second locator spring, also a wave spring, may be disposed between the piston ring and the seal support structure for urging the piston ring in a radial direction.

摘要： A brush seal assembly for a coal pulverizer includes multiple identical assembly segments. Each assembly segment comprises an arcuate brush assembly, a pair of clamping block assemblies and a pair of mounting bolts. The brush assembly includes a brush and an adjusting segment having a pair of elliptical openings. A radially inner end of the brush contacts the pulverizer yoke and a radially outer end is connected to the adjusting segment. Each clamping block assembly includes a clamping block, having a circular opening, a threaded rod, and a pair of jam nuts, the rod extending radially from an inner end mounted to the clamping block through the first jam nut, a hole in the adjusting segment, and the second jam nut. Each mounting bolt has a threaded shaft which extends longitudinally upward from the bolt head, through the circular opening of one of the clamping blocks and one of the elliptical openings of the adjusting segment, to a distal end portion which engages an opening of the pulverizer seal housing.
