水压轴向柱塞泵滑靴静压支承中的惯性影响

在油压轴向柱塞泵的滑靴静压支承设计中,通常忽略Navier-Stockes方程中的惯性项,这是因为它较粘性项小得多,对计算结果的影响不大.然而,在水压轴向柱塞泵的研究中,由于水的粘度比油的粘度小得多,因此,惯性项就起着较大的作用.研究了水的流动惯性对支承间隙中的压力及流速分布的影响,从而对水压静压支承设计进行修正,得出更加合理的结果.

INERTIA EFFECT ON HYDROSTATIC BEARING FOR SLIDING SHOE OF WATER HYDRAULIC AXIAL PISTON PUMP

Inertia items in Navier-Stokes equations are often ignored in design of hydrostatic bearing for sliding shoe of oil hydraulic axial piston pump because it is much less than viscosity items and has little effect on computing results. However, in research of water hydraulic axial piston pump, inertia items should play an important role because the viscosity of water is much less than that of oil. The effect of water flowing inertia on the distribution of pressure and velocity in the bearing clearance is studied, water hydrostatic bearing design is revised and more feasible results are drawn.
