摘　　要：为了获得泵腔的润滑孔对泵的输出性能的影响规律,采用数值仿真结合试验验证的方法分析了润滑孔在泵腔周向、径向的不同位置分布以及不同孔径时泵的性能。结果表明:在周向,润滑孔处于泵喷射口朝向一侧的半周时对泵输出总压影响较小,处于另一侧半周时会降低泵输出总压,在180°时的泵输出总压比在45°时的输出总压提高了4.8%;在径向,靠中心位置的润滑流量比靠外缘的润滑流量降低了80%,出口输出总压则提高了2%;当润滑孔周向设在与喷射口距离较远位置附近时,适当增大润滑孔有助于提高泵输出压力,若周向设在距离喷射口较近的位置,则大的润滑孔会降低泵的输出压力。In order to obtain the influence of the lubrication hole of the pump cavity on the output performance of the pump,the different distributions of the lubrication holes in the circumferential and radial positions of the pump cavity and the performance of the pump at different bore diameters were analyzed by numerical simulation in combination with experimental verification.The results show that in the circumferential direction,the lubrication hole has little effect on the total pump output pressure when the lubrication hole is half perimeter of the pump jet port facing one side,and the total pump output pressure will decrease when the hole is at half perimeter on other side,the total pump output pressure at 180°is 4.8%higher than that at 45°.In the radial direction,the lubrication flow near the center is reduced by 80%compared to the lubrication flow near the outer edge,and the total output pressure at the outlet is increased by 2%;When the circumferential direction of the lubrication hole is located near a position distant from the jet port,appropriately increasing the lubrication hole helps to increase the pump output pressure,if the circumference is set closer to the jet port,the large lubrication hole will reduce the output pressure of the pump.
