Abstract
The present invention relates to a system used for inspecting the position of a compressor rotor within a compressor rotor case. A compressor rotor blade is moved about the rotor blade path of the compressor rotor case, a probe holder attached to the rotor blade has a scanning device as part of the holder used for gathering information relative to the compressor rotor case. A fixture attached to the compressor rotor gathers information about the position of the compressor rotor with respect to the compressor rotor case to determine the relative position of both the compressor rotor in relation to the compressor rotor case.
Claims45
A rotor blade system for inspecting a position of a compressor rotor within a compressor rotor case, the system comprises a probe holder dimensioned for releasable attachment to a rotor blade of said compressor rotor, a first fixture for immobilizing the rotor blade, a second fixture for operably moving said probe holder and a probe thereof about a rotor blade path of said compressor case.
A probe holder according 18, wherein at least part of said body is made of a non-scratchable material for preventing damage to a surface of the rotor blade.
A method for inspecting a position of a compressor rotor within a compressor rotor case, comprising:
- a) releasably securing a first fixture to a compressor rotor blade for immobilizing said rotor blade,
- b) releasably securing a probe holder and probe thereof to the rotor blade for scanning a rotor case blade path and transmitting collected information thereof,
- c) establishing a zero-point between said probe and the rotor case,
- d) releasably attaching a second fixture to a central portion of said compressor rotor case;
- and
- e) actuating the second fixture for rotating the compressor rotor at least one revolution about the rotor case blade path.
