Analysis Based on Orthogonal Experiment of Lubrication Performance of Micro-texturing Valve Core on Coal Mine Water Hydraulic Relief Valve
摘要
Abstract
Taking the coal mine water pressure relief valve core as the research object,we set the regular distribution of the micro-texturing process in the valve core surface to improve its lubrication characteristics.By the orthogonal experiment method,we select L16 (45) orthogonal table,consider 5 factors include the micro-texturing depth,the micro-texturing radius,the clearance of the friction pair,the speed of the valve core and the micro-texturing morphology,design 16 kinds of experiment programs.The model of the micro-texturing valve core is built by CFD,to analyze the surface pressure distribution and the bearing capacity,and determine the micro-texturing morphology optimization model.Results show that:the surface micro-texturing of the valve core can produce hydrodynamic lubrication effect,which can improve the performance of friction and wear.Through the analysis of the simulation results,we can get the importance degree of the factors that affect the bearing capacity of the valve core are as follows:the micro-texturing depth,micro-texturing radius,the micro-texturing morphology,the clearance of the friction pair and the speed of the valve core.By orthogonal experiment we can get the optimization scheme,the bearing capacity of the optimization scheme is 22％ higher than that of the original scheme.关键词
