摘要： An inspection apparatus (40) for in-situ leak testing of the bell seal (30) of a steam turbine (10). The apparatus includes a pair of inflatable bladders (48,52) for defining a sealed volume having the bell seal (30) as its only leakage path. The mass flow rate of pressurized air (70) at various pressures through the bell seal (30) is compared to the known flow rates through a similarly designed bell seal having various degrees of degradation. A camera (60) rotated by motor (62) between the bladders (48,52) provides an indication of the proper positioning of the inspection apparatus (40) and facilitates a visual inspection of the bell seal (30) and retaining nut (42). The inspection apparatus (40) may be inserted into an inlet to the turbine through a disassembled flow control valve without the need for any disassembly of the turbine.

摘要： An inspection apparatus (40) for remote inspection of the trepan radius area (34) of the inlet sleeve (24) of a steam turbine (10). The apparatus (40) provides a sealed volume (50) between a pair of inflatable bladders (46,48) for the introduction of a liquid couplant for the immersion of ultrasonic transducers (42,44). A laser line generator (62) generates a beam of light visible through camera (60) which impinges upon the inlet bell seal (30) when the apparatus (40) is in a proper inspection position within the inlet sleeve (24). Guide vanes (56) provide centering and generate an insertion force during air assisted insertion of apparatus (40). Transducers (42,44) are indexed axially and circumfretially by the independent rotation of axial drive gear (72) and longitudinal drive gear (70) engaged with a pattern of gear teeth (69) formed as a combination of circumferential spur gear teeth and axial rack gear teeth cut into a single surface of a spline shaft (68).

摘要： A tool for forming substantially rectangular cross sections on conduits. Two mateable collars are disposable about the exterior of a conduit and have forming surfaces which can be pressed against the conduit's wall to predetermined extents to cause the conduit to assume the desired outside rectangular dimensions. Such pressing is provided by two threaded fasteners, each of which extend through one of the collar members and into threaded engagement with the mateable collar. The assembled collar configuration may be disengaged from, rotated about, and reclamped on the exterior of the conduit so as to provide uniform wall formation if the shape of the desired conduit permits such collar rotation. To assure complete contact between the conduit's exterior and the forming surfaces of the collar, two wedge members are axially inserted in the conduit's opening.

摘要： A mount is for installing a probe, such as for example, a search coil, in a variety of locations and orientations within an electrical generator, without requiring the rotor of the generator to be removed. The mount includes a block having a longitudinal hole and a plurality of transverse slots intersecting the hole. A plurality of wedges are disposed within the slots. A wedge pin inserted into the longitudinal hole engages the wedges forcing the wedges outward in order to secure the mount and search coil thereon in the desired position within the generator, such as for example, in the air gap between the rotor and stator. A fastening mechanism further secures the mount in place.
