Fluid movers are extensively used in the process industries. New machines are specified, designed, manufactured and installed in a way that ensures their safety and reliability. Existing machines may be upgraded or retrofitted during maintenance or repair. This book describes how improved components and better lubricant application provisions, among other experience-based measures, can safely extend operating life and increase profitability.
Описание: This book - the authors' second book on screw compressors – presents the results of the most up to date methods of three-dimensional modeling of the fluid dymanics and the solid-fluid interaction within these machines, which are still being developed. By including them in the design process, it is possible, not only to predict flow patterns more accurately, and hence improve the design of the critical components, but also to determine how the pressure and temperature distribution within the compressor distorts the rotors and casing and how this, in turn, has an interactive effect on the performance.Such calculating facilities are especially valuable for oil free machines, in which temperature changes are much larger and thus make thermal distortion effects more significant. However, it confers advantages in all cases, as improved machine tools enable manufacturing tolerances to be reduced and hence compressors can be built with smaller clearances. Four examples outline the scope of the applied mathematical model for three dimensional calculation of fluid flow and stresses in the solid parts of the screw machine.

Описание:
The perfect primer for anyone responsible for operating or maintaining process gas compressors.
Gas compressors tend to be the largest, most costly, and most critical machines employed in chemical and gas transfer processes. Since they tend to have the greatest effect on the reliability of processes they power, compressors typically receive the most scrutiny of all the machinery among the general population of processing equipment. To prevent unwanted compressor failures from occurring, operators must be taught how their equipment should operate and how each installation is different from one another.
The ultimate purpose of this book is to teach those who work in process settings more about gas compressors, so they can start up and operate them correctly and monitor their condition with more confidence. Some may regard compressor technology as too broad and complex a topic for operating personnel to fully understand, but the author has distilled this vast body of knowledge into some key, easy to understand lessons for the reader to study at his or her own pace.
This groundbreaking new work is a must-have for any engineer, operator, or manager working with process compressors.
The main goals of this book are to:
Explain important theories and concepts about gases and compression processes with a minimum of mathematics
Identify key compressor components and explain how they affect reliability
Explain how centrifugal compressors, reciprocating compressors, and screw compressors function.
Explain key operating factors that affect reliabilityIntroduce the reader to basic troubleshooting methodologies
Introduce operators to proven field inspection techniques
Improve the confidence of personnel operating compressors by teaching them the basics of compressor theory
Improve compressor reliability plantwide by teaching operating and inspection best practices
Improve communication between operating and supporting plant personnel by providing a common vocabulary of compressor terms
Help processing plants avoid costly failures by teaching operators how to identify early compressor issues during field inspections
