What are the consequences for the operation of a reciprocating compressor if the magnetic center line of the motor is mismeasured during alignment?
Thread Content
What impact does an inaccurate measurement of the distance between the magnetic center lines of the motor when the flywheel is installed after the motor has been aligned on a reciprocating compressor have on the operation of the unit?
Firstly, there is shaft play, which damages the thrust bearings; in addition, it also damages the crank throws, the crosshead slideways, and the cylinder sealing gaskets
Damage to the motor and compressor axial bearings.
The compressor driven by this motor has been in operation for over 3 months without any issues such as increased temperature in the bearing shells or alarms; merely friction occurred between the side of the bearing shell at the motor drive end and the rotor. What’s problematic is that there is an issue with the shaft end, yet the compressor’s thrust ring is undamaged.
