Aerothermal-Mechanical Health Monitoring And Diagnostics Or Turbo-Compressor Sets

Abstract

High speed turbomachinery plays a critical role in today's petrochemical industry. There are very high penalty costs associated with nonavailability and catastrophic failure of critical unspared trains. Additionally the fuel and maintenance costs over the life cycle of plant turbomachinery is very significant. Both of the above factors point to the need for health monitoring and diagnostic systems. The petrochemical industry has in the past placed a heavy emphasis on mechanical (vibration) analysis for both health monitoring and diagnostics. This paper presents a methodology in which both mechanical and aerothermal parameters are utilized for machinery health monitoring, prognosis and diagnosis.
