A HOLDING AND ADJUSTMENT DEVICE FOR ALIGNMENT OF INNER-INNER AND INNER- OUTER CASINGS OF LOW-PRESSURE STEAM TURBINES

摘要

The invention relates to a holding and adjustment device for alignment of inner- inner and inner-outer casings of low-pressure steam turbines, comprising : a main body having a hollow hexagonal head at bottom face; at least two teeth configured on the top face of the main body; a holding ring with threads and a centre hole, the holding ring enabling the device to be attached to the inner- outer casing of the turbine; an eccentric bush having a slot, the main body attached with eccentric bush with least clearance; a rotating handle providing for rotating the holding ring so that eccentric bush and main body can be attached to each other and the holding ring is locked with the outer casing by threading. A hammer and a forged spanner is used for smoothly rotating the main body.
