| 摘 要： | 微型柱塞泵是微型液压驱动系统的核心部分。由于微型柱塞泵进出管和配流阀流道小，使得在研究微型柱塞泵自吸性能时，除了流体重力、惯性力和黏性力外，还要考虑毛细流动效应对微型柱塞泵自吸性能的影响。在对比了流体黏度、管径和浸润角等因素后，对微型柱塞泵自吸过程进行了理论分析。结果表明，微型柱塞泵自吸性能受流体重力、惯性力、黏性力和毛细流动效应共同作用影响，并且在不同管径、流体黏度和浸润角下，各种力的影响程度不同。

| Abstract: | A micro-plunger pump is the core part of micro-hydraulic drive system as a micro-power source. Because inlet-outlet pipes and distributing valve channels of micro-plunger pump are small, when considering self-priming performance of micro-plunger pump, in addition to fluid gravity, inertial force and viscosity, the influence of capillary flow effect on self-priming performance of micro-plunger pump must be considered. We analyze the self-priming process of micro-plunger pump theoretically after comparing the factors such as fluid viscosity, diameter and contact angle. The results show that the self-priming performance of micro plunger pump is influenced by the fluid gravity, inertial force, viscous force and capillary flow effect, and the influence degree of various forces is different under different pipe diameters, fluid viscosity and infiltration angle. |
