Pump Selection And Troubleshooting Field Guide

In the last decade, solar energy has experienced a rapid growth, which brings both environmental and economic benefits. In many countries, there is still no electricity grid extension in rural areas, and in the absence of a reliable electricity supply, farmers have to resort to diesel-based pumping irrigation systems. The solar photovoltaic (PV) system generates clean energy and eliminates the risk of environmental pollution in the form of oil spills, contaminated soil and carbon dioxide emissions. Operation and maintenance of the solar PV pumping system is a technical job that requires specialized knowledge and information to keep the system in working condition and sustainable and in working conditions. For this purpose, this sourcebook is designed to provide information on the design, operation, inspection, troubleshooting, and maintenance of solar PV pumping systems.

This book provides information and tools to assist operators in evaluating treatment plant operational changes (such as the changes in treatment efficiency due to changes in the raw water). and to help operators make corresponding water chemistry or other process changes to keep the plant operating properly. Both operators and system managers can use the analysis tools to more easily understand and operate a plant and be able to identify and correct any plant deficiencies.

This unique field guide discusses in detail the various aspects of heat pump selection, installation, and service. This book covers basic heat pump operation, including: a review of the refrigeration cycle, heat pump configurations, four-way valves, electrical schematics, defrost systems, controls and accessories, the scroll compressor, and service and troubleshooting.

A comprehensive, yet concise handbook dealing with occurrence, exploration, drilling, extraction, and use of groundwater. Includes types of wells, pumps, pump selection, testing of wells, installation, piping systems, composition and purification, with figures and tables to compute yield, and flow in conduits, and troubleshooting wells.

The book presents a comprehensive, yet concise analysis of groundwater occurrence, its development, technology involved in exploration, extraction, and its economical usage.The book makes use of minimum technical jargon, while explaining the basics of drilling, types of wells, their maintenance, development and testing, and selection of pumps. It discusses the causes for wells failing, methods of diagnosis and the pre-emptive and remedial measures, water transmission, composition, and purification. Unlike other natural resources, groundwater is replenished by rainfall. Nevertheless those who depend on groundwater either for industrial or agricultural sustenance should be responsive to certain factors that are significant to the long-term well-being of the water source. Important are: Whether the wells are being over-pumped, or under-pumped; the quantity and cost of water being drawn, whether there is sufficient water underground with optimum replenishment, and systems installed are compatible to the particular hydrological situation and similar such factors. The book attempts, in simplistic language, to link the gap between theory and practice; between the principles of groundwater as a natural science and its application technology. There are a number of pre-calculated tables that serve as a handy reference for Consultants, Drillers and Engineers who deal with groundwater on a day-to-day basis.

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 plans4. 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.
