Unusual PD Pump Pulsation: Pulsations in piping systems can cause serious problems that sometimes require creative solutions

摘要

Acoustic pulsations are not as frequent or common a source of vibrations or dynamics problems in plunger pumps or other liquid pumping systems as they are for gas piping systems. However, when resonant pulsations do develop in a liquid pumping system they tend to be higher in amplitude and can cause more severe problems (e.g. cavitation) than in gas piping systems (Heveron, 1978). Therefore it is very important to have effective pulsation suppression solutions.
