運(yun)(yun)動(dong)(dong)(dong)(dong)粘(zhan)(zhan)度(du)(du)(du)(du)(du)(du)計(ji)(ji)適用(yong)于(yu)測定(ding)液(ye)(ye)(ye)體(ti)石油(you)產品(pin)的(de)(de)(de)運(yun)(yun)動(dong)(dong)(dong)(dong)粘(zhan)(zhan)度(du)(du)(du)(du)(du)(du)。儀器具有計(ji)(ji)時(shi)(shi)試樣運(yun)(yun)動(dong)(dong)(dong)(dong)時(shi)(shi)間，自(zi)動(dong)(dong)(dong)(dong)計(ji)(ji)算運(yun)(yun)動(dong)(dong)(dong)(dong)粘(zhan)(zhan)度(du)(du)(du)(du)(du)(du)的(de)(de)(de)終結果。本方法適用(yong)于(yu)測定(ding)液(ye)(ye)(ye)體(ti)石油(you)產品(pin)（指(zhi)牛頓液(ye)(ye)(ye)體(ti)）的(de)(de)(de)運(yun)(yun)動(dong)(dong)(dong)(dong)粘(zhan)(zhan)度(du)(du)(du)(du)(du)(du)，方法是在某一(yi)(yi)恒定(ding)溫(wen)度(du)(du)(du)(du)(du)(du)下(xia)，測定(ding)一(yi)(yi)定(ding)體(ti)積的(de)(de)(de)液(ye)(ye)(ye)體(ti)在重力流過(guo)一(yi)(yi)個標定(ding)好的(de)(de)(de)玻璃毛細管(guan)粘(zhan)(zhan)度(du)(du)(du)(du)(du)(du)計(ji)(ji)的(de)(de)(de)時(shi)(shi)間，粘(zhan)(zhan)度(du)(du)(du)(du)(du)(du)計(ji)(ji)的(de)(de)(de)毛細管(guan)常數與流動(dong)(dong)(dong)(dong)時(shi)(shi)間的(de)(de)(de)乘積，即(ji)為該溫(wen)度(du)(du)(du)(du)(du)(du)下(xia)液(ye)(ye)(ye)體(ti)的(de)(de)(de)運(yun)(yun)動(dong)(dong)(dong)(dong)粘(zhan)(zhan)度(du)(du)(du)(du)(du)(du)。動(dong)(dong)(dong)(dong)力粘(zhan)(zhan)度(du)(du)(du)(du)(du)(du)可由(you)測得的(de)(de)(de)運(yun)(yun)動(dong)(dong)(dong)(dong)粘(zhan)(zhan)度(du)(du)(du)(du)(du)(du)乘以液(ye)(ye)(ye)體(ti)在當前溫(wen)度(du)(du)(du)(du)(du)(du)的(de)(de)(de)密度(du)(du)(du)(du)(du)(du)所得。

運動粘度計的注意事項：

        1.恒溫浴(yu)內無(wu)恒溫液(ye)或加熱(re)器不能全部浸在恒溫液(ye)內時(shi)，不得啟動(dong)(dong)運動(dong)(dong)粘度計，否則將損(sun)壞加熱(re)器；

        2.運動粘度(du)計外殼應與地(di)面接觸良好以保證安全；

        3.非本廠維(wei)修人員(yuan)不(bu)得隨意拆啟運(yun)動(dong)粘度計；

        4.運動粘(zhan)度(du)計使(shi)用(yong)完畢后，應及時切斷電(dian)源。

        5.在(zai)更換保(bao)險絲或其它(ta)零部件時，應拔(ba)下運動粘度(du)計電源插頭。
