摘要： System, methods, and devices for inspecting generator rotor slot wedges in-situ are provided. The system includes a controller operably connected to a remote-control carriage for transmitting control signals and receiving data. The carriage includes a drive module for moving the carriage into an inspection area, e.g., through an air gap between the rotor and stator, and an inspection module operable to inspect a rotor wedge surface. The inspection module includes a jack assembly and a transducer assembly. The jack assembly is operably connected to the transducer assembly, and configured to elevate the transducer assembly to the rotor wedge surface for inspection.

摘要： Immersion ultrasonic NDE is performed within cavities of inanimate objects, having downwardly directed openings, such as for in situ inspection of steam inlet sleeves and steam inlet necks within steam turbine housings. A shaft assembly has one or more single angle or phased array ultrasonic probes that are affixed on an upstream or distal end. An inflatable bladder is affixed to the shaft on a proximal end of the shaft assembly downstream the ultrasonic probe(s). The shaft is inserted into the cavity opening, and the bladder is inflated to form a fluid tight seal against the cavity. Immersion fluid is introduced upstream the bladder in the volume occupied by the probes. Immersion ultrasonic inspection of the object is then performed.

摘要： Steam turbine engine cross over pipe or other pipe internal inspection is performed with a selectively steerable pipe inspection crawler apparatus with a chassis having a longitudinal axis, with front and rear Mechanum wheels capable of independently-selected forward or rearward driven rotational direction, for selectively steering the apparatus within the pipe interior under control of a human-machine interface (HMI). The crawler apparatus has at least one inspection camera having a field of view, for capturing images of a pipe interior that is also under control of the HMI. Embodiments of the crawler apparatus include a selectively orientable inspection camera and/or a deployable bore scope that is selectively deployed and retracted from a descending section of the cross over pipe.

摘要： Eddy current inspection of the step iron region of a generator stator core lamina insulation is performed while the rotor is in situ, with inspection system (81). The system (81) excites the stator core (26) and then measures any eddy currents indicative of a damaged region. The inspection system carriage (42) and its pivoting extension arm (52) are inserted within the rotor gap (34) while the rotor (22) remains in situ within the generator (20). The EL CID system's eddy current sensing coil assembly (54) includes a Chattock coil (70), which is mounted in a coil housing (56, 58) that is in turn pivotally mounted on a distal end of the extension arm (52). A sensing surface (60) of the coil housing (56, 58) remains in abutting contact with the generator core circumference in the step iron region (32), despite the step-like profile of the core circumference in that region.

摘要： A tool system for tightening a retrightenable wedge system in a slot of a generator stator core is presented. The tool system includes a carriage assembly and a wedge tool assembly that is pivotally coupled to the carriage assembly. The carriage assembly includes motorized drives that axially moves the tool system along the slot and holds the tool system on the slot at an axial position. The wedge tool assembly includes a torqueing socket to tighten the retightenable wedge assembly in the slot. The torqueing socket is driven by a worm gear arrangement.
