    • A shaft seal assembly externally mounted to a high temperature device, such as a gas or steam turbine, having a plurality of rotary shaft sealing brush seals that includes at least one brush seal of wear-compensating construction that possesses a suitably high linear coefficient of expansion so it viscoelestically creeps over time compensating for brush seal wear. In one embodiment, a brush seal closest to the device is formed of an electrically conductive material that electrically grounds a rotary shaft of the device during shaft rotation and at least one other brush seal is formed of filaments of polymeric material, such as heat stabilized nylon, of wear compensating construction. In one preferred embodiment, the filaments of the inner brush seal are made of a self-lubricating metallic or bearing material and at least one other brush seal is formed of an intumescing material that can be of polymeric composition.
    • 外部安装在诸如气体或汽轮机的高温装置上的轴密封组件,其具有多个旋转轴密封刷密封,所述多个旋转轴密封刷密封件包括具有适当高线性膨胀系数的磨损补偿结构的至少一个刷密封件 所以它粘滞地随着时间的推移补偿刷密封磨损。 在一个实施例中,最靠近装置的刷子密封件由导电材料形成,该导电材料在轴旋转期间使装置的旋转轴电接地,并且至少一个其它刷密封由聚合材料的长丝形成,例如热稳定的尼龙 的磨损补偿结构。 在一个优选实施例中,内刷密封件的长丝由自润滑金属或轴承材料制成,并且至少一个其它刷密封由可以是聚合物组合物的膨胀材料形成。

    • A brush seal usable in high temperature sealing applications having brush bristles and a sealing membrane of stress and deflection accommodating construction capable of longitudinal extensibility. Sealing membrane has one portion slidably overlapped with another portion. In one embodiment, membrane is folded over itself providing slidable overlapping in one direction and is formed of overlapping membrane sheets providing slidable overlapping in another direction. In another embodiment, membrane has spaced apart deformation regions providing longitudinal extensibility in accommodating stress and/or deflection. Membrane can be made of metallic foil having a thickness no greater than brush bristle width or diameter and is embeddable in bristles of the brush seal.
    • 可用于具有刷毛的高温密封应用的刷密封件和能够纵向延展的应力和挠曲容纳结构的密封膜。 密封膜具有可滑动地与另一部分重叠的部分。 在一个实施例中,膜自身折叠,提供在一个方向上可滑动的重叠,并且由重叠的膜片形成,从而在另一个方向上提供可滑动的重叠。 在另一个实施方案中,膜具有间隔开的变形区域,其在容纳应力和/或偏转方面提供纵向延伸性。 膜可以由厚度不大于刷毛宽度或直径的金属箔制成,并且可嵌入刷密封件的刷毛中。
