摘要： In a hydrogen cooled generator, a seal casing has a chamber opening radially inwardly for receiving a pair of seal rings forming a fluid film along the interface between the rings and the rotor. A spring biases the seal rings against axial spaced flanges of the seal casing and static oil sealing grooves are provided at the interface of the seal rings and flanges. A brush seal is carried by one or both of the seal rings or by the seal casing and has bristles for engaging the surface of the rotor. The combination of seal rings and brush seal form a low flow fluid film seal maintaining the hydrogen atmosphere and oil on opposite sides of the housing wall and the seal casing segregated from one another.

摘要： A seal is provided around a shaft extending through a cavity in a hydrogen cooled generator. The seal includes a plurality of brush seal structures adapted to reduce flow to/from the cavity to a level where the risk of creating an explosive mixture of gases is minimized. In an embodiment of the invention, a series of brush seals are provided to interface with the rotary shaft so as to define a seal for minimizing the flow of hydrogen out of the cavity. In one preferred embodiment, the seal is composed of first and second brush seal assemblies, each of which is comprised of a plurality of brush seal structures. In another embodiment, spring(s) are provided to urge the brush seal structures into sealing engagement with the rotor. If deemed necessary or desirable, a vent outlet is provided in a cavity wall remote from the hydrogen atmosphere, to remove hydrogen that has leaked through the brush seals.

摘要： A rotatable shaft is mounted in an oil bearing and generates oil mist. One or more brush seals are carried by the bearing housing for substantially sealing the oil mist in the bearing cavity from migration outwardly. The bristles have a diameter in the range of 0.5 to 1.0 mils, preferably about 0.56 mils. The bristles have a stiffness less than 1 psi/mil and preferably about 0.2 psi/mil. The brush seal is mounted on a sheet metal mounting plate, enabling an inexpensive securement of brush seals to the housing.

摘要： The brush seal includes manually-flexible, plastic-containing, brush-seal bristles attached to an elongated bristle holder. The rotary machine has a rotor and stator casing segments with segments of the brush seal positioned one each in a surface groove of a corresponding stator casing segment. In one example, the bristle holder is manually flexible, the bristles and the bristle holder define a monolithic unit, and the brush seal is coiled onto a spool from which a desired length is cut thereby avoiding the necessity of manufacturing a brush seal segment to a specific radius and a specific circumferential length to match a particular stator casing segment.

摘要： A gas-path leakage seal for generally sealing a gas-path leakage-gap between spaced-apart first and second members of a turbine (such as combustor casing segments of a gas turbine). The seal includes a flexible and generally imperforate metal sheet assemblage having opposing first and second surfaces and two opposing raised edges extending a generally identical distance above and below the surfaces. A first cloth layer assemblage has a thickness generally equal to the previously-defined identical distance and is superimposed on the first surface between the raised edges. A second cloth layer assemblage is generally identical to the first cloth layer assemblage and is superimposed on the second surface between the raised edges.

摘要： A flexible magnetic brush seal is employed as a low flow fluid film seal and/or a diffusion and mass transfer prevention seal in a hydrogen generator to seal between a hydrogen atmosphere and a fluid on an opposite side of the seal. The brush seal is formed of a magnetic rubber flexible material, enabling the seal to be flexed and altered in dimension to fit a number of different sealing environments of different dimensions. The magnetic properties of the brush seal enable temporary securement of the brush seal to a brush seal holder prior to final securement.

摘要： In a gas turbine having a chordal hinge seal between an inner rail of each nozzle segment and an annular axially facing sealing surface of a nozzle support ring, a supplemental seal is disposed between the support ring and inner bands of the nozzle segments on a lower pressure side of the chordal hinge seals. To minimize or prevent leakage flow across the chordal hinge seals, a generally U-shaped supplemental seal having reversely folded U-shaped marginal portions is received in a cavity formed in the axially extending sealing surface of the inner rail of the nozzle segment. At operating conditions, the marginal portions seal against the base of the cavity and the annular sealing surface of the nozzle support ring to prevent leakage flow past the chordal hinge seal from entering the hot gas path. To install the supplemental seal, the seal is first compressed and maintained in a compressed state by applying one or more wraps about the supplemental seal or an epoxy to secure the seal when compressed in the cavity. At operating temperatures, the retention means releases the seal to engage marginal portions against opposite sealing surfaces of the nozzle segment and support ring.
摘要翻译：在具有在每个喷嘴段的内轨道和喷嘴支撑环的环形轴向面对的密封表面之间具有弦状铰链密封件的燃气涡轮机中，在较低压力下在支撑环和喷嘴段的内带之间设置补充密封侧面铰链密封。为了最小化或防止跨弦铰链密封件的泄漏流动，具有反向折叠的U形边缘部分的大致U形补充密封件容纳在形成在喷嘴段的内轨道的轴向延伸的密封表面中的空腔中。在操作条件下，边缘部分密封在空腔的底部和喷嘴支撑环的环形密封表面上，以防止通过弦状铰链密封件的泄漏流进入热气路径。为了安装补充密封件，首先将密封件压缩并保持在压缩状态，通过在补充密封件或环氧树脂周围施加一个或多个包装件以在压缩在空腔中时固定密封件。在操作温度下，保持装置释放密封件以将边缘部分接合在喷嘴段和支撑环的相对的密封表面上。
