Patent ID: 7918462

Claim:
A system for facilitating labyrinth packing installation comprising: a tube assembly consisting of one flexible pneumatic tube having a first sealed end, a second open end, one exterior surface, and one interior surface that forms an inner-most cavity, one woven fabric sleeve surrounding the exterior surface of the flexible pneumatic tube, and one pliable metal strip within the inner-most cavity of the flexible pneumatic tube; a pneumatic pressure regulator comprising a pressure gauge, and male and female quick disconnect fittings; the pneumatic pressure regulator being in fluid communication with a pressurized air supply source; the male quick disconnect fitting being attached by a hose clamp to the second end of the flexible pneumatic tube; the female quick disconnect fitting being operatively connected to the pneumatic pressure regulator; whereby the tube assembly can be positioned so as to extend the packing segments in a disassembled rotor casing into a close clearance position for calibration for operational expansion clearance measurements purposes.
