摘要: 滑靴副是水压轴向柱塞泵四个重要摩擦副之一,为保证良好的润滑,采用静压支承结构。通过雷诺数分析滑靴副内部流体流态,柱塞阻尼孔为紊流状态,其长度远小于层流状态,密封带水膜为层流状态,有助于减少泄漏和保证滑靴性能。建立滑靴副模型,运用FLUENT分析不同工作压力和不同流体性质下,流场的压力和流速分布,得出滑靴底部水腔内压力分布均匀且为压力最大区域,是主要承受外界负载的区域;密封带处水膜压力沿半径方向逐渐降低;水腔中心的流速远大于油腔中心的流速,其随工作压力的增大而增大,为滑靴的设计提供一定的理论依据。

Abstract: Slipper pair is one of the most important frictional pairs of hydraulic axial ram pump, which is supported by static pressure to facilitate good lubricating. The fluid in the slipper pair was analyzed by using Reynolds number. The length when the flow in plunger damping hole was turbulence was shorter than that when it was laminar. To reduce the leak and prove the performance of slipper, the moisture film of sealing strip should be laminar. The flow distribution of slipper pair was analyzed by FLUENT after the model of moisture film was created. The distribution of pressure and velocity in the flow was based on different pressure and fluid properties. The area where the pressure was even and maximum was the main area which bore the pressure. The pressure of the moisture film reduced gradually along the radius. The velocity of flow nearby the centrality of the hydrocoel was faster then the centrality of the oil reservoir. It was advanced with the growth of the pressure. Some theories could be evidenced for designing the slipper pair.

Key words: slipper pair, moisture film, FLUENT, flow distribution
