摘要： A turbine spline seal includes an elongated turbine seal member. The seal member has an elongated, imperforate, and manually-flexible first portion and a manually-rigid second portion lengthwise adjoining the first portion. The turbine assembly includes the turbine spline seal and also includes first and second turbine members. The first and second turbine members are spaced apart to define a fluid-path leakage gap therebetween, and the seal member is placed in the gap. Each lengthwise edge of the seal member engages a respective one of two opposing surface grooves of the first and second turbine members.

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。

The members are heated by heating elements receiving controlled power. By increasing or decreasing the power provided to the heating elements, the members are expanded or contracted to move the brush seal segments toward or away from the opposing sealing component.

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 compliant seal assembly for a rotating machine is provided. The seal assembly includes a static member, a movable member and a biasing member. The static member is rigidly fixed to the machine at its fore and aft ends. The movable portion has a first sealing surface configured to seal against a rotating member and a rear surface, which may be exposed to a fluid pressure to urge the first sealing surface toward a sealing position with the rotating member. The static and the movable members further include sealing surfaces at their fore, aft and end faces to seal against leakage of gas between the static and the movable members. The biasing member is configured to support the movable member on the static member and to urge the movable member away from the sealing position so as to reduce force on the rotating member during contact of the rotating member with the first sealing surface of the movable member.

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.
