摘　　要：分析了液压系统的污染来源,通过实验检测了实际液压系统过滤器的过滤比远低于理论过滤比,并提出影响过滤性能的过滤器吸附率的概念,据此推导了液压系统简化的污染控制动平衡方程,并给出了近似条件下的解。本文的实验和理论研究对液压污染控制系统的设计具有指导意义。The injested contaminant in the hydraulic system was analyzed. The filter-rate was very low in the real hydraulic system by the experimentation. The concepts of the desorption ration that is the main infection factor to the filter capability was presented. The dynamic balance equation of hydraulic contamination control system was constructed and the result was given approximately. It is usefull to the design of the hydraulic contamination control system.

关 键 词：液压系统 污染控制 吸附率 污染耐受度
