摘要： A balance weight has first and second margins at right angles to one another with the second margin larger than the first margin. A balance weight groove in a rotor has outer and inner wall portions, with the outer wall portions spaced a distance less than the spacing between the inner wall portions. The balance weight has a central threaded opening receiving a screw and a driving slot in the upper face of the weight. An insertion tool is threaded to the balance weight to insert the balance weight through a turbomachinery access opening into the groove. The tool is rotated to locate the second margins below the outer wall portions of the groove. By inserting a driving tool through the insertion tool, the screw is rotated to lock the balance weight to the rotor and in the groove. Upon removal of the insertion and driving tools, a staking tool is inserted through turbine access opening to stake the balance weight and rotor and the screw and balance weight.

摘要： The flowpath assembly includes inner and outer circular bands 16 and 18, respectively, and a plurality of stator blades 20 extending between the bands. The tip portions 26 of the stator blades and the openings 30 in the outer bands are at least as large as the footprints F of the blades in a radial direction. Thus, the airfoil portions 22 of the blades, which are bowed, tapered and twisted, are receivable through the openings 30 in the outer band 18 during assembly. The tip and root portions 24 and 26, respectively, of the blades are secured in the openings by welding.

摘要： An adjustable labyrinth seal for a steam turbine wherein the packing rings may be displaced from a larger diameter position, affording a relatively larger shaft clearance, to a smaller diameter position, affording a relatively smaller shaft clearance. Steam conduits are provided in the turbine casing communicating with the annular space between the individual packing rings and the grooves in which they are retained. The rings are provided with seals and are so configured as to maintain pressure- retaining contact with the sidewalls of the grooves. Steam, at a pressure in excess of the operating pressure of the individual seal, may be admitted to the annular space of the upstream ring to controllably effect the displacement thereof. Steam, at the turbine inlet pressure, is admitted to the annular spaces of the remaining rings to effect their displacement. In a further embodiment, one or more of the remaining rings may receive pressurized steam from an external source to control precisely the time at which they close.
摘要翻译：一种用于蒸汽轮机的可调式迷宫式密封件，其中填料环可以从较大直径的位置移位，从而提供相对较大的轴间隙到较小直径位置，从而提供相对更小的轴间隙。蒸汽管道设置在涡轮机壳体中，与各个密封环和它们保持的凹槽之间的环形空间连通。环设置有密封件，并且被配置为保持与凹槽的侧壁的压力保持接触。在超过单个密封件的操作压力的压力下的蒸汽可以被允许进入上游环的环形空间，以可控地影响其位移。在涡轮机入口压力下的蒸汽被允许进入剩余环的环形空间以实现它们的位移。在另一个实施例中，一个或多个剩余环可以从外部源接收加压蒸汽，以精确地控制它们关闭的时间。

摘要： Brush seals are employed on steam turbine rotors without the risk of causing thermal rotor bowing and without compromising the sealing performance. In one form, a groove in the rotor has an insert in frictional contact with the brush seal. The non-uniform distribution of heat due to frictional contact between the brush seal and proud portions of the rotor is dissipated within the insert such that adjoining rotor portions are substantially uniformly heated without causing thermal bow. In a further form, a groove or grooves are provided in the rotor surface adjacent to the brush seal and maintain non-uniform heat distribution locally in the rotor without causing thermal bow of the rotor. In another form, a land projects radially outwardly of the rotor surface in contact with the brush seal. The non-uniform distribution of heat due to frictional contact between proud portions of the land and the brush seal dissipates into a uniform distribution of heat in the rotor proper to avoid thermal bowing. In a final form, the brush seal has frictional contact with bucket dovetail or wheel protrusions spaced radially outwardly of the rotor such that non-uniform distribution dissipates into a uniform distribution within the rotor.
摘要翻译：汽轮机转子上使用刷子密封件，而不会导致热转子弯曲并且不影响密封性能。在一种形式中，转子中的槽具有与刷密封件摩擦接触的插入件。由于刷子密封件和转子的骄人部分之间的摩擦接触引起的热量的不均匀分布在插入件内消散，使得相邻的转子部分基本均匀地加热而不引起热弓。在另一种形式中，在转子表面中设置有与刷子密封件相邻的凹槽或槽，并且在转子中局部地保持不均匀的热分布，而不会导致转子的热弓。在另一种形式中，一个脊面与转子表面径向向外突出地与刷子密封接触。由于陆地骄傲部分和刷子密封件之间的摩擦接触导致的热量的不均匀分布在转子中散发成均匀的热分布，以避免热弯曲。在最终形式中，刷子密封件与铲斗的燕尾榫摩擦接触或轮毂径向向外偏离转子，使得不均匀的分布在转子内消散成均匀的分布。
