摘要： A method of manufacturing a brush seal includes wrapping wire about spaced frames to form a pair of wire runs of multiple wire thicknesses. Two pairs of interior plates are inserted between the wire runs at an angle and in spaced relation to one another. Two pairs of plates are applied along the outside of the wire runs parallel to the pairs of interior plates, respectively. By removing the wire run outside the plates and welding along each of the opposite edges of the wire run securing an interior plate, a cut end of a wire run and an exterior plate to one another, and by cutting each wire run preferably in half, four tee shaped bristle packs are formed with the bristles extending at the appropriate angle. By cutting the tee shaped packs to length and rolling the cut pack, a brush seal is formed to the appropriate diameter.

摘要： A seal between rotary and stationary turbine components includes an abradable coating on the surface of the stationary component between axially spaced caulked-in seal strips. The rotatable component includes a plurality of axially spaced teeth interdigitated with the teeth of the stationary component and engaging the abradable coating on the stationary component in the cold condition of the turbine. The teeth on the stationary component have larger clearances to prevent mushrooming of the tips in the event of a transient condition. By utilizing caulked-in teeth, a larger number of seal teeth are provided for the same axial extent as compared with conventional labyrinth seal teeth.

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： A brush seal extends between static and rotary components. The brush seal includes a fence on the high pressure side, a bristle pack behind the fence, a bristle pack backing plate and a pressure plate. The backing plate includes a plurality of circumferentially and radially spaced arcuate slots arrayed in staggered relation about the brush seal segment. The pressure plate includes radially extending grooves opening toward the backing plate and intersecting each of the slots along that radius to afford a substantially uniform distribution of pressure on the downstream side of the bristle backing plate. In another embodiment, the grooves extend along the downstream faces of the bristle backing plate.

摘要： An abradable coating and/or an abrasive coating applied to the rotor of a steam or gas turbine allows the temperature and pressure drop capabilities of conventional brush seal assemblies to be increased. The pressure drop capability of brush seals is closely related to fence height, i.e., the distance between the rotor and the bottom edge of the backing plate supporting the brush seal wire bristles. Application of the abradable or abrasive coating allows the fence height to be reduced and the pressure capability of a brush seal assembly increased commensurately because the risk of the backing plate rubbing against the surface of the rotor, so as to cause damage to the rotor, is reduced. In addition, the backing plate can be made from a higher strength material that can withstand higher temperatures because any contact between the backing plate and the rotor results in no damage to the rotor, but rather a gradual reduction of the backing plate as it wears.
摘要翻译：施加到蒸汽或燃气涡轮机的转子上的可磨损涂层和/或磨料涂层允许增加常规刷子密封组件的温度和压降能力。刷子密封件的压降能力与栅栏高度密切相关，即，转子和支撑刷密封线刷毛的背板的底部边缘之间的距离。可磨损或磨蚀性涂层的应用允许栅栏高度降低，并且刷密封组件的压力能力相应地增加，因为背板摩擦转子表面的风险以对转子造成损坏的风险是减少此外，背板可以由可承受更高温度的较高强度的材料制成，因为背板和转子之间的任何接触都不会损伤转子，而是背衬板磨损时逐渐减小。
