摘要： An insert assembly is provided for a rotary machine wherein the rotary machine comprises a rotor and a casing. The rotor comprises a generally longitudinally-extending axis. The casing is generally coaxially aligned with the axis. The casing circumferentially surrounds and is radially spaced apart from the rotor. The insert assembly comprises a channel circumferentially disposed on the rotor and an insert circumferentially disposed in such channel such that the insert assembly is configured to thermally isolate frictional heat from the rotor to the insert.

摘要： An actuation pressure control system effects actuation of adjustable seal segments between stationary and rotating turbomachinery members. At least one actuator is coupled with each of the adjustable seal segments and controls a position of the seal segments, respectively. A pressure system is disposed within the turbomachinery that measures or estimates ambient pressure representing an actuator back pressure acting against the actuator. A pressure regulator via a controller pressurizes the actuator to a level sufficient for a desired seal operation and controls actuator pressure based on the actuator back pressure.

摘要： Disclosed is an actuator that includes a cylinder having an input port, a piston disposed at least partially inside of the cylinder, and one or more piston rings disposed in a circumferential piston ring groove or grooves. The actuator also includes at least one spring, inserted into the circumferential piston ring groove adjacent to the one or more piston rings and a high pressure side of said piston ring. The spring preloads the one or more piston rings to seal between a low pressure face of the one or more piston rings and a low pressure face of the circumferential piston ring groove. The invention also includes a method for moving an adjustable seal in a radial direction using the piston-ring sealed actuator. The method includes moving the adjustable seal in an axial direction, breaking a primary axial contact between the adjustable seal and a primary sealing face.

摘要： A brush seal segment includes a plurality of bristles disposed between a pair of backing plates. The bristles are welded to one another adjacent their proximal ends and to the edges of the backing plates remote from the bristle tips. An end plate is welded to the end faces of the backing plates at each of the opposite ends of the segment. Each end plate terminates at approximately one-half the length of the bristles along the end face to prevent the bristles from bending circumferentially and axially during handling while maintaining substantially uniform flexibility of the bristles throughout the entire length of the segment.

摘要： A method for making a brush-tooth seal, such as a brush-tooth seal which is attachable to a turbine stator, includes obtaining a seal carrier having a groove and having seal teeth and obtaining a brush seal having bristles with tips. The brush seal is engaged in the groove and then attached to the seal carrier. Then, the tips of the bristles of the attached and engaged brush seal are cut, such as with an electric discharge machining (EDM) wire, at a predetermined distance from the longitudinal axis of the seal carrier.

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。
