Background
This complex rotor part stands about 7 ft. tall, has a 40” diameter at its widest point, and weighs 1,000 lbs. The part has several rows of “HPT BLADES” and is covered with tiny holes.
Problem
First, this tall, 1,000 lb. part had to be fixtured so that the blades and other surfaces were not damaged. Second, while the outside of the part needed to be spray washed, water could not be allowed to go through the tiny surface holes and get inside the part.
 Solution
The following is done to hold the part on the washer’s turntable:
1) While the part is laying horizontally, caps are screwed onto the shaft ends
2) A lift chain is hooked to one of the caps and the part is hoisted to a vertical position
3) The part is lowered onto the turntable with the bottom shaft fitting into a female fixture
4) Once the part is seated on the fixture, a pin is inserted to lock the lower shaft cap to the fixture.
To prevent water from entering the part, the rotor is pressurized. A compressed air line is connected to the upper shaft cap. Compressed air is forced into the part and has no place to go but out the small surface holes. Air shooting out stops any water from getting inside.
