Troubleshooting Rotating Machinery: Including Centrifugal Pumps and Compressors, Reciprocating Pumps and Compressors, Fans, Steam Turbines, Electric Motors, and More 1st Edition by Robert X. Perez and Andy P. Conkey.
Preface by Robert X. Perez and Andy P. Conkey.
Troubleshooting is part science and part art. Simple troubleshooting tables or decision trees are rarely eff ective in solving complex, real-world machine problems. For this reason, the authors wanted to off er a novel way to attack machinery issues that can adversely aff ect the reliability and effi – ciency of your plant processes. Th e methodology presented in this book is not a rigid “cookbook” approach but rather a fl exible and dynamic process aimed at exploring process plant machines holistically in order to understand and narrow down the true nature of the problem. Th roughout this book, the term process machinery will be used to refer to rotating machinery commonly encountered in processing plants, such as centrifugal pumps and compressors, reciprocating pumps and compressors, fans, steam turbines, and electric motors.
Our first book in this series, Is My Machine OK? deals, in large part, with assessing process machinery in the field. Th is guide takes the assessment process to the next level by helping operators, mechanics, managers, and machinery professionals better troubleshoot process machinery in-situ, i.e., in the fi eld. To cover the topic of troubleshooting, the authors will cover the following topics in this book:
• What fi eld troubleshooting means and entails
• How to use this guide as a complement to Is My Machine OK?
• Using the “who, what, when, where, why” troubleshooting methodology
• How to use cause maps to investigate possible causes
• Real-world case studies
• How to use machine-specifi c troubleshooting tables
To be successful, the troubleshooter must be persistent, open-minded and disciplined. Once field data is collected, an unbiased, logical approach to the fi nding is required to hone in on the most probable source of an observed symptom (or symptoms). Without a comprehensive and logical analysis of the findings, the investigator is only guessing, which wastes valuable time and resources. We hope those reading and using this guide will fully utilize the ideas and concepts presented to minimize maintenance cost and risk levels associated with machinery ownership.
