Method and apparatus hydraulic turbine repair

An apparatus adapted for use in a chamber having a substantially cylindrical configuration formed by a chamber liner inner wall, for purposes of repairing, resurfacing, or otherwise refinishing said liner wall, said apparatus comprising:

• a positioning structure positioned in said chamber;
• means for said positioning structure relative to said liner wall to facilitate repair, resurfacing or refinishing of said liner wall;
• grinding means mounted to said positioning structure and adapted to engage said liner wall in a grinding fashion for said repair, resurfacing or refinishing of said liner wall;
• energizing means for selectively energizing said grinding means;
• and
• adjustable connection means for mounting said grinding means and for adjusting said position of said grinding means relative to said positioning structure, with the adjustment being in a substantially radial direction relative to a central axis of said chamber so as to adjust the engagement and disengagement of said grinding means with said liner wall.

An apparatus adapted to use in a chamber having a substantially cylindrical configuration formed by a chamber liner inner wall, for purposes of repairing, resurfacing, or otherwise refinishing said liner wall, said apparatus comprising:

• a positioning structure positioned in said chamber;
• means for rotating said positioning structure relative to said liner wall to facilitate repair, resurfacing or refinishing of said liner wall;
• a vertical support structure mounted to said positioning structure substantially adjacent said liner wall;
• grinding means adapted to selectively engage said liner wall in a grinding fashion for said repair, resurfacing or refinishing said liner wall;
• energizing means for selectively energizing said grinding means;
• support means for mounting said grinding means and said energizing means;
• and
• adjustable connection means coupled to said support means and to said vertical support structure for mounting said grinding means to said vertical support structure, and for adjusting the position of said grinding means relative to said vertical support structure, with the adjustment being in a substantially radial direction relative to a central axis of said chamber so as to adjust the engagement and disengagement of said grinding means with said liner wall.
