This practical reference describes the occurrence of cavitation in a centrifugal pump, and how unacceptable cavitation can be avoided. It explains cavitation problems such as hydraulic performance loss, hydrodynamically or thermodynamically induced surging, and cavitation erosion. General guidelines for acceptable operation conditions, such as, net positive suction head (NPSH) margins and minimum flowrates, are presented along with evidence and logic for these proposed guidelines.Failure to open the valve on pump start will, of course, lead to immediate vapour locking so very reliable procedures are required. Maintenance procedures. It is very easy to forget that the leak-off system isolating valve must be re-openedanbsp;...
