如何處理(li)液壓系統(tong)中的(de)(de)(de)液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)油(you)(you)的(de)(de)(de)污(wu)染問題?液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)系(xi)(xi)統(tong)(tong)小編(bian)指出,液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)油(you)(you)是(shi)水和(he)空氣(qi)(qi)(qi)混合的(de)(de)(de),新型液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)油(you)(you)具有(you)吸(xi)水性,含有(you)微量水;液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)系(xi)(xi)統(tong)(tong)停(ting)止(zhi)工作時,系(xi)(xi)統(tong)(tong)溫度(du)下降,空氣(qi)(qi)(qi)中(zhong)(zhong)的(de)(de)(de)水蒸氣(qi)(qi)(qi)凝(ning)結(jie)成(cheng)水分子(zi),混入(ru)(ru)油(you)(you)中(zhong)(zhong)。當(dang)液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)油(you)(you)中(zhong)(zhong)混入(ru)(ru)水時,會降低液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)油(you)(you)的(de)(de)(de)粘度(du),促進液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)油(you)(you)的(de)(de)(de)氧化和(he)分解(jie),還會形成(cheng)氣(qi)(qi)(qi)泡(pao),使(shi)液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)油(you)(you)的(de)(de)(de)平穩功能變(bian)差,造成(cheng)氣(qi)(qi)(qi)蝕(shi)。液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)油(you)(you)可以溶(rong)解(jie)一(yi)部分空氣(qi)(qi)(qi),有(you)時還會吸(xi)入(ru)(ru)氣(qi)(qi)(qi)泡(pao)。在液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)油(you)(you)中(zhong)(zhong)混入(ru)(ru)空氣(qi)(qi)(qi)會加速液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)油(you)(you)的(de)(de)(de)氧化和(he)分解(jie),還會產(chan)生噪音、氣(qi)(qi)(qi)蝕(shi)、振蕩(dang)等現象。
顆粒狀(zhuang)污物(wu)混(hun)入液壓(ya)(ya)油(you)中,在(zai)加工(gong)、安(an)裝、儲存和(he)運輸過程中,污物(wu)混(hun)入液壓(ya)(ya)系統(tong)和(he)部(bu)件中;使用中,漏(lou)氣或漏(lou)水構(gou)成(cheng)不溶物(wu);金屬零件在(zai)使用中磨(mo)(mo)損后的磨(mo)(mo)損碎屑;空氣中灰(hui)塵的混(hun)合等。,所有這些都容(rong)易在(zai)液壓(ya)(ya)油(you)中形成(cheng)顆粒污垢。液壓(ya)(ya)油(you)中混(hun)入顆粒狀(zhuang)污垢,簡單構(gou)成(cheng)磨(mo)(mo)粒磨(mo)(mo)損,降(jiang)低(di)液壓(ya)(ya)油(you)的光滑度和(he)冷卻(que)功能。
固體顆粒污染有幾個原因:
1.液(ye)壓系統本身原有的殘余(yu)雜質,如制造和安(an)裝過程中出現的雜質,尚未完全清除;
2.新油(you)(you)含(han)有雜質(zhi),因為油(you)(you)流經的油(you)(you)管(guan)和儲(chu)油(you)(you)的油(you)(you)桶(tong)含(han)有雜質(zhi);
3.室(shi)外工作環境惡劣,各種飛料顆粒浸入液壓系統;
4.在(zai)液壓系統維護(hu)期間,部(bu)件和(he)管道的拆卸和(he)組裝過程中有(you)污染物(wu)侵(qin)入,或者在(zai)加(jia)油和(he)換油過程中使用了不干凈的過濾(lv)容器帶來的污染物(wu)。
