摘要： The invention relates to a turbine (1) having a rotor (2), which has a bladed area (3) for rotor blades (4) and a thrust compensation piston (5). The thrust compensation piston (5) has a hot side (6), which faces the bladed area (3), and a cold side (7), which is remote from the bladed area (3). On one side, a feed (14) for sealing fluid (15), which is assigned to the cold side (7), and a leakage fluid feed (12), which is flow-connected to the bladed area (3), open out into a mixing area (13), and on the other side a discharge line (16) branches off from the mixing area. The invention also relates to a method for discharging hot leakage fluid (17). In a turbine (1), the leakage fluid (17) passes through a radial gap (12) between a thrust compensation piston (5) of a rotor (2) and a stationary turbine part (11) and is mixed with a cooler sealing fluid (15) and discharged.

摘要： A low friction bearing comprises a first element having a first surface. A second element having a second surface is rotatable about a centerline relative to the first element. A flow passage extends radially outward between the first surface and the second surface. The first surface and the second surface are separated by a fluid flow. The two surfaces are complementary and positioned in close proximity. The bearing finds a preferred application in a fluid cooled turbine to create a high temperature, high efficiency turbine.

摘要： A pump has a thrust bearing has a casing with an inlet port and a discharge port. A shaft is positioned within the pump. A thrust bearing is coupled to the shaft. A pressure alterable bearing cavity is located within the casing. The pressure alterable cavity allows the axial thrust on the shaft from the impellers to be counteracted. The thrust bearing has an annular seal coupled with respect to the casing disc is coupled to the shaft and positioned adjacent the seal. The seal and the disc have a gap therebetween. A feedback pipe couples the bearing cavity to the inlet port. As the axial thrust acting on the shaft changes, the gap between the seal and the disc also changes. The changing of the gap changes the pressure within the bearing cavity. The disc and thus the shaft are repositioned in response to the change in the bearing cavity pressure change.

摘要： A device for compensating an axial thrust in a turbomachine is described. A compensating piston is disposed in a compensation chamber and contains at least one radial seal operant between a rotor and a housing of the turbomachine in addition to a running wheel secured to the rotor. An axial seal is provided between a side surface pertaining to the compensating piston and the housing. An axial gap width is variable in the same manner as the axial displacement of the running wheel occurring during operation and the compensating piston is impinged upon by the pressure prevailing in the compensating chamber according to the axial gap width.

摘要： A turbo-compressor having a housing and at least one rotor shaft pivotably supported in the housing, with a free shaft end and with a rotor connected with the other end of the rotor shaft. The free end of the rotor shaft facing away from the rotor projects into a pressure chamber connected with the housing, and is acted upon by a pressurized fluid whose force of pressure compensates for the force of the axial thrust acting on the rotor. Thus, the starting friction of the compressor is lower and drive motors of lower output target can be utilized.

摘要： An orifice plate assembly for a gas turbine engine that facilitates extending a useful life of bearing assemblies within the gas turbine engine is described. Each orifice plate assembly is coupled in flow communication with an engine air source, and includes a first body portion and a second body portion. The first body portion includes a channel and a flow opening. The channel is sized to receive the second body portion, such that the second body portion may slide with respect to the first body portion. The orifice plate assembly is adjustable after engine shutdown to regulate bearing loading.

摘要： A thrust control system for use with a turbocompressor having gas bearings. More specifically, the system concerns an arrangement of gas bearings for use in a turbocompressor or other device where a large temperature difference between the turbine and the compressor housing could cause unacceptable performance of the turbocompressor thrust bearings if located in proximity of the turbine and compressor wheels. This danger is obviated in the system by relocating the gas thrust bearings so as to minimize the axial distance between them. This configuration affords the additional advantage that gasses of different composition may be separately used as a seal gas in cases where the process gas in the turbine and compressor are incompatible.
摘要翻译：一种与具有气体轴承的涡轮压缩机一起使用的推力控制系统。更具体地说，该系统涉及用于涡轮压缩机或其他装置的气体轴承的布置，其中涡轮机和压缩机壳体之间的较大温差可能导致涡轮压缩机止推轴承的不可接受的性能，如果位于涡轮机和压缩机轮毂附近。通过重新定位气体推力轴承以便使其间的轴向距离最小化，系统避免了这种危险。这种结构提供了另外的优点，即在涡轮和压缩机中的处理气体不兼容的情况下，不同组成的气体可以单独用作密封气体。
