Abstract

The article presents the qualitative and quantitative composition results of mechanical admixtures in the aircraft hydraulic fluid. An experimental study was carried out to determine the effect of the size and mechanical admixture concentration on the wear and jamming of the hydraulic distributor. In the working fluid at a certain mass concentration of admixtures and pressure in the system, the dependence of spool pairs jamming the aviation equipment’s hydraulic drive on the pollution particle diameter was determined. The critical size of particles and their mass concentration was defined. The surface wear of the spool pair from an aircraft hydraulic valve is shown.

工作液中的机械混合物对飞机液压驱动的线轴对的磨损和干扰的影响

摘要

本文介绍了飞机液压油中机械混合物的定性和定量组成结果。进行了一项实验研究，以确定尺寸和机械掺合料浓度对液压分配器的磨损和阻塞的影响。在一定混合气质量浓度和系统压力下的工作流体中，确定了堵塞航空设备液压驱动的线轴对对污染颗粒直径的依赖性。确定了颗粒的临界尺寸及其质量浓度。显示了来自飞机液压阀的阀芯对的表面磨损。
