    Abstract: 動的なシャフトシールアセンブリは、内ケースおよび外ケースを有する。 回転可能なシャフトの周囲の動的な封止のため、両ケースの間にシール要素が固定されるように内ケースと外ケースとは互いにクランプされる。 内ケースには、シール除去器具と係合可能なプルタブが、内ケースと統合されて形成されている。 これにより、シールアセンブリが設置される孔からシールアセンブリを簡単に除去できる。

    Abstract: PROBLEM TO BE SOLVED: To provide a sealing method of liquid-cooled stator bar that surely and effectively prevents leakages occurring at the connection between the coupling and the wires of a water-cooled generator. SOLUTION: The method includes a step for blasting (42) the inner surface of the connection between coupling and wires with CO 2 pellet, in order to remove free cooper oxide that interfere with a proper sealing between an epoxy resin and the copper surface of the connection. After spraying pressurized air for cleaning the surface and removing particulate matters, an epoxy resin (44) is applied to a brazed connection, and then the connection between coupling and wires is evacuated. Next, the epoxy resin is made to filled surely into all the fractures or cracks on the connecting surface by releasing the vacuum, and the tendency of the epoxy resin to be peeled is minimized or eliminated.
