一個液壓系統(tǒng)的好壞不僅取決于系統(tǒng)設(shè)計的合理性和系統(tǒng)元件性能的的優(yōu)劣，還因系統(tǒng)的污染防護和處理，系統(tǒng)的污染直接影響液壓系統(tǒng)工作的可靠性和元件的使用壽命，據(jù)統(tǒng)計，國內(nèi)外的的液壓系統(tǒng)故障大約有70%是由于污染引起的。

折疊 油液污染對系統(tǒng)的危害主要如下

1）元件的污染磨損
油液中各種污染物引起元件各種形式的磨損，固體顆粒進入運動副間隙中，對零件表面產(chǎn)生切削磨損或是疲勞磨損。高速液流中的固體顆粒對元件的表面沖擊引起沖蝕磨損。油液中的水和油液氧化變質(zhì)的生成物對元件產(chǎn)生腐蝕作用。此外，系統(tǒng)的油液中的空氣引起氣蝕，導(dǎo)致元件表面剝蝕和破壞。
2）元件堵塞與卡緊故障
固體顆粒堵塞液壓閥的間隙和孔口，引起閥芯阻塞和卡緊，影響工作性能，甚至導(dǎo)致嚴(yán)重的事故。
3）加速油液性能的劣化
油液中的水和空氣以其熱能是油液氧化的主要條件，而油液中的金屬微粒對油液的氧化起重要催化作用，此外，油液中的水和懸浮氣泡顯著降低了運動副間油膜的強度，使?jié)櫥阅芙档汀?br />R900912543 LC32DB20E7X/
