摘要
针对超高压海水泵配流阀运动滞后所引起海水泵容积效率降低的问题。分析了导致配流阀滞后的主要原因,建立了数学模型,运用AEMSim软件进行仿真。研究结果表明:随着余隙容积的增大,配流阀开启滞后现象越明显。随着吸液阀阀芯质量增加,对阀芯开启滞后影响较小,关闭滞后影响较大。在设计超高压海水泵时,要尽量减小柱塞腔的余隙容积和减小配流阀阀芯质量。
Focus on the problem that the volume efficiency of the super-high seawater pump decreases due to the lag of the valve movement of super high pressure seawater pump.The main reasons leading to the lag of the valve are analyzed,and the mathematical model is established.The simulation is carried out by using AEMSim software.The results show that with the increase of clearance volume,the opening lag of distributing valves becomes more obvious.With the mass of the suction valve spool increases,the influence on the opening lag of the spool is small,and the closing lag has a greater influence.When designing the super-high pressure seawater pump,the clearance volume of the plunger cavity and the mass of the pool should be reduced as much as possible.
