二级脱盐水对液压泵容积效率的影响

摘要

通过分析二级脱盐水的特性以及液压泵无因次特性中动力黏度对泵容积效率的影响，探讨二级脱盐水对液压泵容积效率的影响。结果表明：采用二级脱盐水作为工作介质对提高液压泵的容积效率是有利的，但增加了液压泵的加工难度。%Based on analyzing the characteristics of twice desalted water and the influence of dynamic viscosity in dimensionless characteristic on pump's volumetric efficiency, the effect of twice desalted water on pump's volumetric efficiency was discussed. The result shows that it is beneficial to improve pump's volumetric efficiency adopting twice desalted water as media, but the machining of pump is more difficult.
