High Vibration Due to Steam Turbine Deposits
MetadataShow full item record
This presentation provides a case study how to correctly deal with increased vibration on a steam turbine that drives a compressor. After the machine had not operated for a week, vibration level increased 5 times during its re-startup. The vibration was dominantly composed of 1X component. An in-depth review of vibration data as well as possible root-causes is demonstrated, to rule out some possible malfunctions. Balancing would be a quick fix to let this machine back in service, based on vibration data. What actions should we take, and is balancing would work in this case?
