簡要描述: 石(shi)油產品運(yun)動(dong)粘(zhan)(zhan)(zhan)度(du)自(zi)動(dong)測定儀(yi)IN-ND是依(yi)據國家標準《GB265-88石(shi)油產品運(yun)動(dong)粘(zhan)(zhan)(zhan)度(du)測定法》設計制(zhi)造(zao)的(de)專用測試儀(yi)器,適用于測定液(ye)體石(shi)油產品的(de)運(yun)動(dong)粘(zhan)(zhan)(zhan)度(du)。本儀(yi)器具有(you)計時(shi)試樣運(yun)動(dong)時(shi)間,自(zi)動(dong)計算運(yun)動(dong)粘(zhan)(zhan)(zhan)度(du)的(de)最終結果。本方(fang)法適用于測定液(ye)體石(shi)油產品(指牛頓液(ye)體)的(de)運(yun)動(dong)粘(zhan)(zhan)(zhan)度(du),其單位(wei)為m2/s。
IN-ND石油(you)(you)產品運(yun)(yun)動(dong)粘(zhan)(zhan)(zhan)(zhan)度(du)(du)(du)自(zi)動(dong)測定(ding)(ding)儀是(shi)依據國家標(biao)準《GB265-88石油(you)(you)產品運(yun)(yun)動(dong)粘(zhan)(zhan)(zhan)(zhan)度(du)(du)(du)測定(ding)(ding)法(fa)》設計(ji)制造的專(zhuan)用(yong)測試儀器,適(shi)(shi)用(yong)于測定(ding)(ding)液體石油(you)(you)產品的運(yun)(yun)動(dong)粘(zhan)(zhan)(zhan)(zhan)度(du)(du)(du)。本儀器具有計(ji)時(shi)試樣運(yun)(yun)動(dong)時(shi)間(jian),自(zi)動(dong)計(ji)算運(yun)(yun)動(dong)粘(zhan)(zhan)(zhan)(zhan)度(du)(du)(du)的最(zui)終(zhong)結果(guo)。本方(fang)法(fa)適(shi)(shi)用(yong)于測定(ding)(ding)液體石油(you)(you)產品(指(zhi)牛頓液體)的運(yun)(yun)動(dong)粘(zhan)(zhan)(zhan)(zhan)度(du)(du)(du),其(qi)單位為(wei)m2/s,通(tong)常在(zai)實際中使用(yong)為(wei)mm2/s。動(dong)力粘(zhan)(zhan)(zhan)(zhan)度(du)(du)(du)可由測得(de)(de)的運(yun)(yun)動(dong)粘(zhan)(zhan)(zhan)(zhan)度(du)(du)(du)乘以液體的密(mi)度(du)(du)(du)求得(de)(de)。本方(fang)法(fa)是(shi)在(zai)某(mou)一恒定(ding)(ding)的溫(wen)(wen)度(du)(du)(du)下(xia)(xia),測定(ding)(ding)一定(ding)(ding)體積(ji)的液體在(zai)重力下(xia)(xia)流過(guo)一個標(biao)定(ding)(ding)好的玻璃毛細管粘(zhan)(zhan)(zhan)(zhan)度(du)(du)(du)計(ji)的時(shi)間(jian),粘(zhan)(zhan)(zhan)(zhan)度(du)(du)(du)計(ji)的毛細管常數與流動(dong)時(shi)間(jian)的乘積(ji),即為(wei)該溫(wen)(wen)度(du)(du)(du)下(xia)(xia)測定(ding)(ding)液體的運(yun)(yun)動(dong)粘(zhan)(zhan)(zhan)(zhan)度(du)(du)(du)。該溫(wen)(wen)度(du)(du)(du)下(xia)(xia)運(yun)(yun)動(dong)粘(zhan)(zhan)(zhan)(zhan)度(du)(du)(du)和同溫(wen)(wen)度(du)(du)(du)下(xia)(xia)液體的密(mi)度(du)(du)(du)之積(ji)為(wei)該溫(wen)(wen)度(du)(du)(du)下(xia)(xia)的動(dong)力粘(zhan)(zhan)(zhan)(zhan)度(du)(du)(du)。
