旋轉粘度計NDJ-79儀器的工(gong)作原理：

儀(yi)器的(de)驅(qu)動(dong)(dong)(dong)(dong)(dong)是靠一個微型的(de)同步電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)，它(ta)以750 r/min的(de)恒(heng)速旋轉(zhuan)(zhuan)(zhuan)(zhuan)，幾乎不(bu)受荷載和(he)電(dian)源電(dian)壓(ya)變化(hua)的(de)影響。電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)的(de)殼(ke)體(ti)(ti)采用懸掛式安(an)裝(zhuang)，它(ta)通過轉(zhuan)(zhuan)(zhuan)(zhuan)軸帶動(dong)(dong)(dong)(dong)(dong)轉(zhuan)(zhuan)(zhuan)(zhuan)筒(tong)旋轉(zhuan)(zhuan)(zhuan)(zhuan)，當(dang)轉(zhuan)(zhuan)(zhuan)(zhuan)筒(tong)在被測液體(ti)(ti)中旋轉(zhuan)(zhuan)(zhuan)(zhuan)時收到粘(zhan)(zhan)滯(zhi)(zhi)阻(zu)(zu)力(li)(li)作(zuo)用，從(cong)而(er)產(chan)生(sheng)反(fan)作(zuo)用力(li)(li)使電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)殼(ke)體(ti)(ti)偏(pian)轉(zhuan)(zhuan)(zhuan)(zhuan)，電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)殼(ke)體(ti)(ti)與兩根(gen)一正(zheng)一反(fan)安(an)裝(zhuang)的(de)金(jin)屬游絲(si)相連，殼(ke)體(ti)(ti)的(de)轉(zhuan)(zhuan)(zhuan)(zhuan)動(dong)(dong)(dong)(dong)(dong)使游絲(si)產(chan)生(sheng)扭矩(ju)。當(dang)游絲(si)的(de)例句與粘(zhan)(zhan)滯(zhi)(zhi)阻(zu)(zu)力(li)(li)矩(ju)達(da)到平衡時，與電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)殼(ke)體(ti)(ti)相連接的(de)指(zhi)針便(bian)在刻度(du)盤上(shang)指(zhi)出(chu)某一數(shu)值，此數(shu)值與轉(zhuan)(zhuan)(zhuan)(zhuan)筒(tong)所受粘(zhan)(zhan)滯(zhi)(zhi)阻(zu)(zu)力(li)(li)成正(zheng)比(bi)，于是刻度(du)讀數(shu)乘(cheng)上(shang)轉(zhuan)(zhuan)(zhuan)(zhuan)筒(tong)因子就表示動(dong)(dong)(dong)(dong)(dong)力(li)(li)粘(zhan)(zhan)度(du)的(de)量值。
