Über dieses Buch

This book offers professionals working at power plants guidelines and best practices for vibration problems, in order to help them identify the respective problem, grasp it, and successfully solve it. The book provides very little theoretical information (which is readily available in the existing literature) and doesn’t assume that readers have an extensive mathematical background; rather, it presents a range of well-documented, real-world case studies and examples drawn from the authors’ 50 years of experience at jobsites. Vibration problems don’t crop up very often, thanks to good maintenance and support, but if and when they do, most power plants have very little experience in assessing and solving them. Accordingly, the case studies discussed here will equip power plant engineers to quickly evaluate the vibration problem at hand (by deciding whether the machine is at risk or can continue operating) and find a practical solution.

Inhaltsverzeichnis

Frontmatter

Chapter 1. Basics of Vibrations

Abstract

This chapter mainly deals with the relationship of vibration excitation and vibration response of systems. Firstly, we analyze the different vibration signal types and the different vibration measurements units.

Franz Herz, Rainer Nordmann

Chapter 2. Instrumentation and Measurement

Abstract

For vibration analysis and troubleshooting, nowadays almost worldwide frequency analyzers based on Fast Fourier Transformers (FFT) are used.

Franz Herz, Rainer Nordmann

Chapter 3. Fault Analysis: Vibration Causes and Case Studies

Abstract

This chapter contains a collection of various case studies from 1969 up to now, covering almost every vibration event having taken place in power plants worldwide.

Franz Herz, Rainer Nordmann

Chapter 4. Jobsite Balancing

Abstract

Jobsite balancing cannot be considered as a balancing method in order to correct the mass unbalances of the rotors (with the exception of a re-blading action during an overhaul jobsite).

Franz Herz, Rainer Nordmann

Chapter 5. Vibration Limits

Abstract

Here are the vibration limits from ISO ((International Organization for Standardization). They had been issued by the ISO between 1995 and 2009 by the vibration committee.

Franz Herz, Rainer Nordmann

Chapter 6. Some Hints to Identify Vibration Problems

Abstract

This is a list of practical hints in order to identify vibration problems. They can direct the solution process into the right direction and could be the basis of the problem elimination.
