高速航空齿轮泵间隙对效率影响研究
Research on Influences of High-speed Aviation Gear Pump Clearances on Efficiency
摘要
Abstract
In order to solve the problems of the effect of high-speed aviation gear pump clearances on the efficiency,a flow field simulation was established and combined with theoretical model analysis to study the effects of different radial and end face clearances on internal leakage and efficiency,as well as to explore the optimal radial and end face clearances at different speeds,and establish multiple groups of orthogonal experiments for verification.The results show that as the speed increases,the optimal end face clearance sizes also increase,and as the speed increases,the effect of the clearance sizes changes on the efficiency of the fuel gear pumps decrease.关键词
