Simulation Analysis of Pulsation Characteristics of Axial Piston Pump

The emergence of “digital hydraulic” makes many industrial fields put forward higher requirements for the performance of piston water pump, and realizes the control of piston water pump, and realizes the digital control of it. But because the efficiency of hydraulic drive is not high, to carry out a wide range of adjustment, need to go through the complex mechanical energy - hydraulic energy conversion, so the efficiency is very high, pressure loss is also very large. Therefore, taking a new type of double row piston pump with flow distribution as an example, the pulsation characteristics of axial piston pump are theoretically analyzed, and the flow pulsation and capacity utilization are simulated by computer. The simulation results show that the closed-loop and integration of components continue to improve, components can be modular assembly, easy maintenance, clean appearance, smaller volume, less pipeline connection, can effectively prevent leakage and pipeline loss caused by too many pipeline interfaces. It can be seen that the control method based on fast switching valve controlled pump effectively promotes the improvement of flow pulsation and capacity utilization.
