为了适应液压系统的使用要求,严加控制液压系统的污染,保持液压油的清洁,已引起液压系统的设计、使用和维修工作者的日益重视。液压油中含有颗粒性污垢,使滑动部分磨损加剧,使阀芯卡滞,把节流孔或阻尼孔堵塞,加速密封件的磨损,引起系统各种故障,缩短液压元件的使用寿命。液压油中的污垢等于原有的污垢量加上入侵的污垢减掉清除的污垢。系统在工作过程中不断有污垢侵入油液,其中有外界的污尘杂物,也有零件磨损和油液氧化而产生的污垢。污染控制的主要手段是用滤油器来清除污垢颗粒和杂质。滤油器不断从油液中清除污垢,经过一段时间滤清后,油液中的污垢量达到动平衡,应将动平衡时的污垢量控
In order to meet the hydraulic system requirements, strictly control the hydraulic system of pollution, to keep the hydraulic oil clean, hydraulic system has been caused by the design, use and maintenance workers pay increasing attention. Hydraulic oil contains particles of dirt, so that the sliding part of the wear and tear worse, the spool stuck, the throttle or orifice clogging, accelerated seal wear, causing system failure, shorten the life of hydraulic components. The amount of dirt in the hydraulic oil is equal to the amount of dirt present plus intruded dirt minus the removed dirt. System in the course of their work continue to invade the dirt, which has the outside world of debris, but also parts wear and oil oxidation generated dirt. The main means of pollution control is to use oil filters to remove dirt particles and impurities. Oil filters continue to remove dirt from the oil, after a period of filtration, the amount of dirt in the oil to achieve dynamic balance should be measured when the soil volume control
