摘　　要：配流阀是阀配流式水压柱塞泵的重要部件,它影响水压柱塞泵的整体性能,其中包括容积效率、噪声等。通过系统的对比实验,研究了配流阀阀座材料对水压柱塞泵容积效率和噪声的影响。实验结果表明配流阀阀座材料对水压柱塞泵的容积效率影响不大,而对噪声影响明显,杨氏模量越大噪声越大。Port valve is a key component of water piston pump.It has influences on the pump＇ s overall performance including volumetric efficiency and noise characteristic.By systematic contrast experiments,this paper research the influence of the port valve seat＇ s material on the volumetric efficiency and noise characteristic of the pump.The results show that the material of the port valve seat has little effect on the volumetric efficiency,but has a great effect on the noise which is higher when the material＇ s Young＇s modulus is larger.
