Successful Vibration Trouble-Shooting of Large Power Plant Rotating Machinery

This paper presents several recent case studies where the application of cutting-edge measurement and computer modeling have been successfully combined to correctly diagnose and fix power plant rotating machinery excessive vibration problems. These case studies include large turbogenerators and feed water pumps. Each case presented here shows an overall trouble-shooting strategy appropriate to the specific problem symptoms, and describes the measurement and computer modeling phases that successfully resolved the specific problem in each case.
