1.防止杂质污物进入系统液压系统是靠液压油传递动力的,其泵、阀、缸、马达等液压元件运动副间有很好的配合表面,加工精度和表面光洁度高,另外液压元件中许多小孔道、节流缝隙、阻尼小孔等,在使用中要保持液压油清洁,防止混入杂质污物,否则就会损害系统元件,降低使用寿命,产生各种故障,如:划伤液压元件运动副表面,加快相对运动零件的磨损,使泄漏增加;杂质将阀芯卡住,不能正常移动。使阀芯动作失灵;杂质将安全阀或回油阀垫起,关闭不严而泄油。导致提升农机具缓慢;可能使节流阀通道或阻尼小孔堵塞,油液不畅通,使液压元件不能正常工作;使油箱滤网堵塞,造成油泵吸
1 to prevent impurities and dirt into the system Hydraulic system is powered by hydraulic oil transmission, and its pumps, valves, cylinders, motors and other hydraulic components have a good fit between the surface movement, machining accuracy and surface finish high, the other hydraulic components Many small channels, throttle gap, damping holes, etc., in use to keep the hydraulic oil clean to prevent mixing impurities dirt, otherwise it will damage the system components, reduce service life, resulting in a variety of failures, such as: scratching hydraulic Component movement surface, accelerate the relative movement of parts wear, so that leakage increases; impurities will spool stuck, can not move normally. So that the valve spool failure; impurities will be safety valve or return valve pad from the closure of the strict and drain. Leading to slow agricultural machinery enhancements; may throttle passage or damping holes blocked, the oil is not smooth, so that the hydraulic components can not work properly; plug the fuel tank filter, causing the pump suction
