Turbine Vibrations

> What are the reasons for high vibrations in turbines?

Alignment error is occurring due to climate change also. Reason for vibration are:
Misalignment
Rotor unbalance
Higher oil pressure
Coupling problem.
Bearing clearance
Many times facing false tripping due to improper installation of the vibration sensor.

The cause of high vibration

1. Worn out bearings
2. Lack of Lubrication
3. Bent Shaft
4. Misalignment of shaft coupling
5. Improper balancing of load (Imbalance of load)
6. Water in oil lubrication
7. suet blockage in the Orifice line
8. Improper axial radial clearance
