6、clude the followi ng:首要，设备元件易发生突发毛病。这种突发性的毛病首要仍是因为固体颗粒而致使的元件突然性的损坏或短暂性的举措失灵。液压元 件运动副的合作空隙通常为 515卩m,关于阀类元件，当污染颗粒进入运动件之间时，会划伤外表，并切削出新的磨粒，加重磨损, 使合作空隙扩展，或许阻塞节省孔、阻尼孔，使其功能改动，致使振 荡和举措失灵；关于泵类元件，污染物颗粒会使滑动有些（柱塞泵 的柱塞和缸孔、缸体、配流盘）磨损加重，发热，致使泵的功率下降;对液压缸来说，污染颗粒会加快密封件的磨损，使走漏量加大，下降功率。污染颗粒也有可能使缸筒或活塞杆拉伤而作废。First,equipme

10、备元件功能阑珊。这种毛病的方式首要是因为磨损而致使的。这种毛病是能够意料，它往往是一个逐步的进程并不像前文咱们讲到那种突发性的状况而致使的。 体系中的污染物会加快液压控制阀滑动零件的磨损，致使内漏或阀内串油，使阀芯、阀套之间的摩擦力添加，阀的响应速度下降，加快液压泵、液压马达及液压缸磨损，损坏密封，形成表里走漏。致使失效的污染物首要是水分和空气。Secon dly,the hydraulic equipment components fun cti on dim.First the wrong waybecause of wear and cause.
