WebSep 24, 2024 · A piston pump works in the following way: First of all, an electric motor or engine supplies power to the crankshaft. As the crankshaft gets power, it turns and delivers its rotary motion to the connecting rod. The connecting rod receives rotary motion by the crank, transforms it into the reciprocating motion, and sends this reciprocating ... WebSep 28, 2024 · The ripple in the outlet flow from a high-pressure piston pump is caused by pressure pulses in the piston cavity when it rotates through the transition region of the valve plate. We propose a parametric design that optimizes the transition region structure of a piston pump valve plate to reduce the ripple in the outlet flow. For a high- pressure … by63777换哪了
