Sub-Synchronous Vibration on Centrifugal Compressor with Tilt-Pad Bearings
Abstract
This presentation provides a success story that sub- synchronous vibration was eliminated on a centrifugal compressor. The sub-synchronous vibration originally occurred at high operational speed on this 5-stage hydrogen recycle centrifugal compressor supported by tilt-pad bearings. Vibration data is reviewed to find its root-cause. Each possible malfunction is discussed to see if it was likely the root-cause. It is shown that sub-synchronous vibration not caused by surge or stall could still happen even with tilt-pad bearings. A solution was implemented to successfully resolve the issue.
