Dear Experienced panel
I would like to share one concern about high casing vibration (1x rpm) in horizontal direction of pedestal showed in picture attached.
the vibration is 10 mm/sec -rms.
the another Steam Turbine pedestal vibration is 1 mm/sec.
the question are?
1.- can we allow this part of machine vibrate with this severity?
2.- can the grouting issue to be the cause of this high vibration?
3.- can some resonance frequency be the cause?
please I will wait your appreciate comments.
