Pump dynamic operational conditions result in extreme transient events that can enhance the response of piping networks. The predominant transients during rapid startup and shutdown are mainly studied for centrifugal pumps scarce reciprocating pumps. Our study extends conventional steady-state analysis to include effect pump loading on pulsatile flow-induced acoustics vibrations a complex netwo...

The structure and dynamics of a reciprocating pump liquid end affect the volumetric efficiency net positive suction head. To match kinematics with theoretical parameters, valve motion flow visualization tests computational fluid (CFD) analyses were performed on wing-guided bevel discharge in horizontal quintuple single-acting pump. test results showed that maximum displacement opening closing d...

This paper developed a 3D physical model of the hydraulic end high-pressure liquid hydrogen reciprocating pump to research dynamic characteristics valve system. Based on mesh technology, we analyzed coupling and plunger motion spool force considering leakage model, closure gap, compressibility hydrogen. Further, effect spring stiffness preload laws valve. Finally, pressurization test was conduc...
