一个液压系统的好坏不仅取决于系统设计的合理性和系统元件性能的的优劣，还因系统的污染防护和处理，系统的污染直接影响液压系统工作的可靠性和元件的使用寿命，据统计，国内外的的液压系统故障大约有70%是由于污染引起的。
折叠 油液污染对系统的危害主要如下
1）元件的污染磨损
油液中各种污染物引起元件各种形式的磨损，固体颗粒进入运动副间隙中，对零件表面产生切削磨损或是疲劳磨损。高速液流中的固体颗粒对元件的表面冲击引起冲蚀磨损。油液中的水和油液氧化变质的生成物对元件产生腐蚀作用。此外，系统的油液中的空气引起气蚀，导致元件表面剥蚀和破坏。
2）元件堵塞与卡紧故障
固体颗粒堵塞液压阀的间隙和孔口，引起阀芯阻塞和卡紧，影响工作性能，甚至导致严重的事故。
3）加速油液性能的劣化
油液中的水和空气以其热能是油液氧化的主要条件，而油液中的金属微粒对油液的氧化起重要催化作用，此外，油液中的水和悬浮气泡显着降低了运动副间油膜的强度，使润滑性能降低。
