Discussion on the method of final bearing pad head clearance.
Thread Content
A steam turbine has a 280mm journal during the installation stage. After the oil runs out, the tiles are turned over and the tile clearance is rechecked. The installation master is said to be a senior technician. The picture below shows his method of placing the lead wire on the shaft to press the tile top clearance. Let's discuss it with friends.
The placement method is correct. Measure the top clearance of the radial bearing.
It’s on the right axis! Top clearance
Isn’t the axis-lifting method good for measurement? :o

Personal opinion: Spherical tiles need to be turned before pressing the lead wire to allow the tiles to self-align.
Use a dial indicator and a magnetic gauge base to measure more accurately using the axis-lifting method.
