摘要： An active retractable seal assembly is configured for use between a rotating component and a stationary component of turbo machinery is disclosed. The seal assembly includes a seal mounted to the stationary component. The seal is movable towards and away from the rotating component between a respective closed position and an open position as a function of pressure drop across the seal. The seal includes an active seal segment, a non-active seal segment, and a fluid by-pass circuit. The fluid by-pass circuit is configured for directing fluid around the active seal segment to reduce pressure drop across the active seal segment thereby resulting in the active seal segment moving towards an open position under the action of one or more biasing devices while maintaining the non-active seal segment in a closed position.

摘要： A fiberoptic multi-parameter sensing system for monitoring turbomachinery system shaft static and dynamic torques, vibration modes and associated operation status includes a multi-furcated fiber bundle based optical splitter configured to transmit light to a surface of at least one turbomachinery system shaft through a plurality of optical fiber bundles disposed at a plurality of locations in proximity to the surface of the at least one shaft, in which the plurality of locations together are arranged in a substantially axial direction between the ends of the at least one shaft. The system further includes an array of high-temperature bifurcated fiber bundle based reflectance probes to receive reflectance signals from the shaft surface and send to an array of photosensitive detectors, configured to detect dynamic light reflected from the at least one turbomachinery system shaft surface in response to the transmitted light during rotation of at least one turbomachinery system shaft and generate dynamic reflected light signals there from. A sensing mechanism is configured to determine a torque or vibration on at least one turbomachinery system shaft in response to the dynamic reflected light signal signatures based on time-domain and frequency-domain signal processes.

摘要： A shaft seal serves to reduce leakage between a rotating shaft and a static shell. The shaft seal includes a plurality of compliant plate members, each having a root and a tip. The compliant plate members are secured to the static shell at their root in facing relation. The tips of the compliant plate members define a sealing ring between the static shell and the rotating shaft. An axial flow resistance member is disposed within the compliant plate members and serves as a barrier to axial leakage flow between the compliant plate members.

摘要： A method for overhauling a steam turbine to increase its power without increasing its overall length. Existing seal assemblies containing seals other than brush seals are replaced with longitudinally-shorter replacement seal assemblies having only brush seals. An existing turbine section, such as a high-pressure turbine section, is replaced with a longitudinally-longer replacement turbine section having additional stages (i.e., additional rows of rotating buckets or blades).
