Informationen zum Autor Ron Palgrave is a retired pump designer and specialist in the hydraulic design and performance of centrifugal pumps. He has nearly 60 years’ experience with 5 manufacturers. He has written several technical papers, magazine articles, and is the author of the 1st edition of Troubleshooting Centrifugal Pumps and their Systems. He has been granted several patents relating to pump technology. Mr. Palgrave currently practices part-time and is one of the most experienced hydraulic engineers in the industry. Klappentext Centrifugal pumps are not complicated machines. Often they consist of a few castings that are pierced by a number of wrought parts. Despite the simplicity of this ubiquitous machine! it is still capable of posing quite complex problems during its operation. The hydraulic influence of the associated piping system is often less than obvious and adds a further dimension to this complexity. Modern cost constraints have more and more lead pump plant designers to contemplate departures from established practice with the result that old lessons are having to be re-learnt. Zusammenfassung Written for novices! this volume explains how centrifugal pumps and their attendant pipework function! before moving on to the more difficult task of solving problems and troubleshooting such systems.
