In order to improve the performance of the plunger pump, aiming at the problems of flow pulsation and pressure overshoot of the plunger pump, a new compound slot flow distribution buffer tank structure is proposed. CATIA modeling software is used to obtain the overflow area curve of the valve plate through Boolean operation. Through the secondary development of the software, the overflow area curve of the valve plate under different parameter values can be obtained efficiently. Then the pressure, flow and other related parameters of the pump can be observed in the AMESim model of the plunger pump. The results show that the flow pulsation and pressure overshoot can be effectively reduced when the depth Angle is 7°, the width Angle is 90° and the composite aperture is 0.8 mm.

摘要

In order to improve the performance of the plunger pump, aiming at the problems of flow pulsation and pressure overshoot of the plunger pump, a new compound slot flow distribution buffer tank structure is proposed. CATIA modeling software is used to obtain the overflow area curve of the valve plate through Boolean operation. Through the secondary development of the software, the overflow area curve of the valve plate under different parameter values can be obtained efficiently. Then the pressure, flow and other related parameters of the pump can be observed in the AMESim model of the plunger pump. The results show that the flow pulsation and pressure overshoot can be effectively reduced when the depth Angle is 7°, the width Angle is 90° and the composite aperture is 0.8 mm.
