Opis

Positive Displacement Pumps is a current reference guide for positive displacement pumps for both traditional and state-of-the-art testing methods, and serves as a bridge between textbooks and manufacturer's literature by providing equipment testing practices based on technical know-how, practical experience, and academic theory. With its simple, practical focus, this book not only is a resource guide to any engineer's task, but also adds important information to the overall literature of pump fundamentals and operating reliability:

• Written for field users, and terminology concisely defined.
• A mentoring guide highlighting areas for troubleshooting problem-solving when performance criteria are not met.
• Produced with industry consensus and gone through the same rigorous technical review process as other ETPC procedures.

The first edition of the AIChE manual on evaluating positive displacement pumps

Positive Displacement Pumps: A Guide to Performance Evaluation is the latest text in the AIChE Equipment Testing Procedure series. It provides pump users with concise, easy–to–follow procedures for testing various types of pumps in the field. The manual covers both traditional and state–of–the–art testing methods and takes into account the "imperfect" realities of actual field conditions. User–friendly and complete with numerous helpful illustrations and tables, this reference includes:

• Definitions of major terms, with explanations, conversion factors, and nomenclature

• Coverage of diverse types of positive displacement pumps: gear; lobe; multiple screw; vane; progressive cavity; diaphragm; and piston/plunger

• Descriptions of test preparation logistics, safety precautions, instruments, methods of measurement, standardized tests, and other tests

• Coverage of pump–testing for applications handling non–Newtonian fluids

This is the hands–on reference for chemical engineers, plant managers, and other professionals responsible for evaluating positive displacement pumps. It fills the gap between manufacturers′ literature and textbooks and provides practical, effective guidance on troubleshooting and problem–solving in the field.
