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： 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.
