Download or read book Centrifugal Pump Technology and Pump Cavitation written by Dr M a Zaher and published by CreateSpace. This book was released on 2015-01-25 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Centrifugal pump technology involves a broad spectrum of flow phenomena, which have a profound impact on design and operation through the achieved efficiency, the stability of the head-capacity characteristic, component failure due to fatigue, as well as material damage caused by cavitation, hydro-abrasive wear or erosion corrosion. Operation and life cycle costs of pumping equipment depend to a large extent on how well these phenomena and the interaction of the pump with the system are understood. The book comprises thirteen chapters covering: theory of centrifugal pump impeller, design of mixed flow impellers, pump casing, hydraulic performance, leakage-disk friction and mechanical losses, water hammer, special operating conditions, and its applications. The book also describes cavitation in pumps, and how unacceptable cavitation can be avoided with the aid of an inducer or using a bleeding system. It explains cavitation problems such as hydraulic performance loss, hydro-dynamically or thermodynamically induced surging, and cavitation erosion/corrosion. The book aims to be simple as is compatible with reasonably complete treatment of the subject. The mathematics has been kept as elementary as possible and many of the standard proofs have been simplified. This book is intended for professional engineers, researchers, specialist students, plant operators and maintenance personnel, plant engineers, and consulting engineers.

Download or read book Centrifugal Pumps written by Dimitris Papantonis and published by BoD – Books on Demand. This book was released on 2012-02-24 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: The structure of a hydraulic machine, as a centrifugal pump, is evolved principally to satisfy the requirements of the fluid flow. However taking into account the strong interaction between the pump and the pumping installation, the need to control the operation, the requirement to operate at best efficiency in order to save energy, the provision to improve the operation against cavitation and other more specific but very interesting and important topics, the object of a book on centrifugal pumps must cover a large field. The present book examines a number of these more specific topics, beyond the contents of a textbook, treating not only the pump's design and operation but also strategies to increase energy efficiency, the fluid flow control, the fault diagnosis.

Download or read book Hydrodynamics of Pumps written by Christopher E. Brennen and published by Cambridge University Press. This book was released on 2011-03-28 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrodynamics of Pumps is a reference for pump experts and a textbook for advanced students. It examines the fluid dynamics of liquid turbomachines, particularly pumps, focusing on special problems and design issues associated with the flow of liquid through a rotating machine. There are two characteristics of a liquid that lead to problems and cause a significantly different set of concerns than those in gas turbines. These are the potential for cavitation and the high density of liquids, which enhances the possibility of damaging, unsteady flows and forces. The book begins with an introduction to the subject, including cavitation, unsteady flows and turbomachinery, basic pump design and performance principles. Chapter topics include flow features, cavitation parameters and inception, bubble dynamics, cavitation effects on pump performance, and unsteady flows and vibration in pumps - discussed in the three final chapters. The book is richly illustrated and includes many practical examples.

Download or read book Operator S Guide to Centrifugal Pumps written by Robert X. Perez and published by Xlibris Corporation. This book was released on 2008-09-22 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: We work in an industry where economic success is heavily dependent on the collective performance of our processing equipment and their operators. Without highly trained and confident operators we can never hope to realize the full potential of our complex processes. Formal and informal training must be provided regularly if continuous process and reliability gains are to be expected. There are no shortcuts to operational excellence. One training topic essential to every operators education is that of centrifugal pumping technology. The ever-present centrifugal pump is one of the workhorses of the process world, tirelessly moving fluids, ranging from the innocuous to the toxic and flammable, from one stage of the process to the next. We would be hard pressed to find a processing unit inside our complexes without a few of these in service. Their shear numbers and variety can make their mastery a challenge. This book was specifically written for process operators who regularly deal with centrifugal pumps, addressing principally those variables and factors under their control, while limiting design theory and mathematics to a minimum. The following topics and content are covered: 1. Importance of equipment reliability and what role operators play in this mission. 2. Centrifugal pump operating characteristics 3. Mechanical seals and their related seal flush plans 4. What operators should know about electric motors 5. Lubrication basics 6. Troubleshooting basics 7. How to start a pump reliability program By the end of the book, the reader should possess a clear understanding of how to operate and monitor their pumps. Three handy references are also contained in the book to answer questions as they arise in the field: 1) Operators Guide to API Flush Plans, 2) Illustrated Glossary of Centrifugal Pump Terms, 3) Glossary of Electric Motor Terms, and 4) Useful Centrifugal Pump Formulas. This book can be used as a self-paced, self-taught short course or as a companion to a live prepared short course for both inexperienced and seasoned operators. It can also serve as a handy field guide after completion of the course. The ultimate mission of this book is to provide the latest generation of operators a body of knowledge that is relevant, complete, and practical in an industrial setting for years to come.
