    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: 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: 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 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.

A support spaces the hot sheet and the cold sheet apart. A generally planar fastening collar is affixed to the portion of the stud extending through the cold sheet. A first length is defined by the portion of the stud extending through the cold sheet to a distal end of the stud. A second length is defined between a first planar surface of the collar facing the cold sheet and a second planar surface of the collar opposite the first surface. Each of the first and second lengths is less is less than a diameter of the main body of the stud.
