Case Study: Charge Compressor Turbine Vibration - Diagnostic/Risk Assessment
Reducing downtime and sustaining high production rates are essential for companies to remain competitive. A 36MHP steam turbine experienced sudden high vibration. Through use of vibration analysis, selective external case cooling, and altering of specific operating conditions, continued safe production was provided for eight months until an overhaul opportunity became available. The analysis of machine vibration data, operating conditions and interlock changes, use of external case cooling will be discussed. Subsequent machine inspection findings and failure analysis will also be provided.
