为改善水压安全阀阀芯润滑性能,在阀芯表面加工微造型。在建立球冠形、圆柱形表面微造型几何模型基础上,利用基于N-S方程的CFD方法分析2种微造型对阀芯润滑性能的影响,并着重分析面积率、深度2种参数下阀芯表面的压力分布的规律。
To improve the hydraulic valve spool lubrication performance, the spool surface machining micro-molding. Based on the geometrical model of spherical crown and cylindrical surface, CFD method based on Navier-Stokes equations was used to analyze the effect of two micro-shapes on the lubrication performance of the valve core. The effects of two parameters of area ratio and depth on the surface of the valve core The pressure distribution of the law.
