潤滑油破乳化試驗油樣

試驗油樣

為了更有效地驗證上述3種試(shi)驗方法間(jian)的相(xiang)關性(xing),在選擇試(shi)驗油時,考慮了如下幾(ji)方面(mian)的因素:

選(xuan)擇的(de)(de)試(shi)(shi)驗(yan)(yan)(yan)(yan)油(you)(you)(you)是(shi)一(yi)些(xie)正在使用(yong)的(de)(de)潤滑油(you)(you)(you)，如汽輪機(ji)油(you)(you)(you)、液(ye)壓(ya)油(you)(you)(you)、壓(ya)縮機(ji)油(you)(you)(you)等(deng),這些(xie)試(shi)(shi)驗(yan)(yan)(yan)(yan)油(you)(you)(you)中所含的(de)(de)添加劑種類比(bi)較多(duo),對破乳(ru)(ru)化性能(neng)的(de)(de)影響比(bi)較大(da),而且(qie)每種試(shi)(shi)驗(yan)(yan)(yan)(yan)油(you)(you)(you)都取了(le)6個不(bu)同(tong)批次的(de)(de)油(you)(you)(you)樣,具有較廣(guang)泛的(de)(de)代(dai)表性;選(xuan)擇的(de)(de)試(shi)(shi)驗(yan)(yan)(yan)(yan)油(you)(you)(you)的(de)(de)質量指標中都規定了(le)破乳(ru)(ru)化試(shi)(shi)驗(yan)(yan)(yan)(yan)項目,而且(qie)每種試(shi)(shi)驗(yan)(yan)(yan)(yan)油(you)(you)(you)的(de)(de)破乳(ru)(ru)化試(shi)(shi)驗(yan)(yan)(yan)(yan)所采用(yong)的(de)(de)試(shi)(shi)驗(yan)(yan)(yan)(yan)方法(fa)也不(bu)相(xiang)同(tong)。選(xuan)用(yong)這些(xie)試(shi)(shi)驗(yan)(yan)(yan)(yan)油(you)(you)(you)作為驗(yan)(yan)(yan)(yan)證(zheng)油(you)(you)(you)品更(geng)有實際使用(yong)意義;

③選擇的(de)試(shi)驗(yan)(yan)(yan)(yan)油(you)(you)(you)的(de)破(po)(po)乳(ru)化(hua)(hua)性(xing)能(neng)(neng)有(you)很大(da)的(de)差別,有(you)的(de)試(shi)驗(yan)(yan)(yan)(yan)油(you)(you)(you)破(po)(po)乳(ru)化(hua)(hua)時間(jian)在(zai)1 ~2min左右(you),有(you)的(de)試(shi)驗(yan)(yan)(yan)(yan)油(you)(you)(you)破(po)(po)乳(ru)化(hua)(hua)時間(jian)在(zai)25~ 30min左右(you)。使用(yong)破(po)(po)乳(ru)化(hua)(hua)性(xing)能(neng)(neng)有(you)一定(ding)差距的(de)油(you)(you)(you)作試(shi)驗(yan)(yan)(yan)(yan)油(you)(you)(you),有(you)利于(yu)試(shi)驗(yan)(yan)(yan)(yan)方法和(he)試(shi)驗(yan)(yan)(yan)(yan)儀器(qi)加以區(qu)別,同時也可考查(cha)試(shi)驗(yan)(yan)(yan)(yan)儀器(qi)的(de)分(fen)辨(bian)率(lv)和(he)準確性(xing);選擇的(de)試(shi)驗(yan)(yan)(yan)(yan)油(you)(you)(you),除了單一的(de)油(you)(you)(you)品外,還用(yong)其中破(po)(po)乳(ru)化(hua)(hua)性(xing)能(neng)(neng)好的(de)油(you)(you)(you)品和(he)破(po)(po)乳(ru)化(hua)(hua)性(xing)能(neng)(neng)差的(de)油(you)(you)(you)品以不同的(de)比例配制了10個混(hun)合試(shi)驗(yan)(yan)(yan)(yan)油(you)(you)(you)樣,這(zhe)樣可考查(cha)油(you)(you)(you)品在(zai)使用(yong)過程(cheng)中-一旦發生(sheng)混(hun)油(you)(you)(you)時,它們對破(po)(po)乳(ru)化(hua)(hua)性(xing)能(neng)(neng)的(de)影響。
