摘　　要： 为了开展水压轴向柱塞泵研究,研制了高压水驱动系统试验台.该试验台能完成水压泵、马达和阀的性能试验以及水压缸的同步试验.用该试验台对某排量为25.3mL/min的高压水压轴向柱塞泵进行了动静特性和吸水能力试验.试验结果表明,该水压轴向柱塞泵的响应速度为1.1ms,但在转速低于1000r/min时随着压力的提高容积效率下降明显.减小泄漏是提高水压泵性能的关键. A test rig for high-pressure water driven systems was developed to meet the requirements of the performance test on water pumps, motors and valves, as well as synchronized tests on water cylinders. A high-pressure water axial piston pump with an output capacity of 25.3mL/min was tested on the test rig. The test result shows that the response time of the pump is 1.1ms, but its volumetric efficiency decreases obviously with an increase in pressure at speed less than 1000r/min. It is concluded that reducing leakage is one of the key issues to improve the performances of high-pressure water pumps.
