  • NDJ-79旋轉粘度計

    NDJ-79旋轉(zhuan)(zhuan)(zhuan)(zhuan)粘度計(ji)的(de)(de)驅(qu)動(dong)是靠一個微(wei)型(xing)的(de)(de)同步電(dian)(dian)(dian)動(dong)機(ji)(ji),它以750 r/min的(de)(de)恒速旋轉(zhuan)(zhuan)(zhuan)(zhuan),幾乎不(bu)受荷(he)載和電(dian)(dian)(dian)源電(dian)(dian)(dian)壓變化(hua)的(de)(de)影響。電(dian)(dian)(dian)動(dong)機(ji)(ji)的(de)(de)殼(ke)體(ti)采(cai)用懸掛式(shi)安裝(zhuang),它通(tong)過(guo)轉(zhuan)(zhuan)(zhuan)(zhuan)軸帶動(dong)轉(zhuan)(zhuan)(zhuan)(zhuan)筒(tong)旋轉(zhuan)(zhuan)(zhuan)(zhuan),當轉(zhuan)(zhuan)(zhuan)(zhuan)筒(tong)在(zai)被測液體(ti)中旋轉(zhuan)(zhuan)(zhuan)(zhuan)時收(shou)到粘滯阻力作用,從而產(chan)生(sheng)反作用力使電(dian)(dian)(dian)動(dong)機(ji)(ji)殼(ke)體(ti)偏轉(zhuan)(zhuan)(zhuan)(zhuan),電(dian)(dian)(dian)動(dong)機(ji)(ji)殼(ke)體(ti)與(yu)兩根一正一反安裝(zhuang)的(de)(de)金屬(shu)游絲相連,殼(ke)體(ti)的(de)(de)轉(zhuan)(zhuan)(zhuan)(zhuan)動(dong)使游絲產(chan)生(sheng)扭矩。
