Pulsation dampening in suction and discharge systems for PD pumps

摘要

There are many specific requirements for the selection and use of dampeners for reducing fluid pressure pulsations generated by positive displacement reciprocating pumps. By analyzing the nature of pressure pulsation, V Larry Beynart shows thereal benefits of installing these devices. Pressure pulsations are reduced, he says, NPSH is increased, and service life is longer and more efficient.
