Troubleshooting Turbomachinery Using Startup And Coastdown Vibration Data.
Accurate and meaningful condition monitoring is necessary to prevent both severe equipment damage and unnecessary shutdowns. One of the most important aspects of condition monitoring is the evaluation of startup and shutdown vibration data. A considerable amount of upfront time must be committed to gather condition data when the machinery is known to be in good condition to provide an adequate picture of the current condition. Examples are given of problems that were correctly evaluated only through access and comparison to past startup/shutdown data as well as information obtained from a rotordynamic model of the system.
