Turbomachinery Health Measurement Application And Misapplication - Part II.

Abstract

In Part I of "Turbo machinery Health Measurement – Application and Misapplication" (Proceedings of the 17th Turbomachinery Symposium, 1988) the fundamentals of machinery monitoring were presented. This tutorial is presented with the assumption that the reader understands all the basic measurement tools and how they operate. The person who uses these tools to determine the internal state of rotating equipment must be thoroughly familiar with how these tools work individually and in concert with other tools. While the monitoring process must be customized for each class of equipment, the degree of scrutiny is often limited by available resources and the economic justifications. Computer based monitoring systems are rapidly closing the gap between permanent monitoring and routine periodic monitoring. The attempt is made to guide the user toward using his monitoring equipment and human resources to maximize effectiveness and avoid common mistakes. A discussion of the most common instrumentation usage is presented, along with the pitfalls associated with misapplications.
