    摘要: A shaft seal reduces leakage between a rotating shaft such as a rotor and a stator. The shaft seal or shingle seal includes a plurality of compliant-plate members attached to the stator in facing relation. The compliant-plate members define a sealing ring between the stator and the rotating shaft. Each of the compliant-plate members includes a plurality of shingles, where adjacent compliant-plate members are disposed relative to each other such that the shingles are at least partially staggered in a direction of axial leakage.

    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 method and seal assembly for a rotary machine including a rotary component and a stationary component is provided. The method includes providing a seal housing including a front plate and a back plate that is spaced from the front plate such that a cavity is defined between the front plate and the back plate. The method also includes coupling a plurality of flexible compliant plates to at least one of the seal housing and the stationary component such that the compliant plates are spaced from the front plate and the back plate within the cavity, and coupling at least one projection to at least one of the seal housing and the compliant plates such that the at least one projection facilitates reducing flow through at least one of a first axial gap and a second axial gap that are defined between the seal housing and the compliant plates.

    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: A bling nozzle/carrier interface design for a steam turbine is provided wherein there is limited contact between the carrier (casing, shell) to allow for ease of assembly. There is also limited contact in strategic locations to both reduce the roll, or downstream deflection, of the inner portion and to improve disassembly due to limited contact in areas where corrosion can occur.
