  熱水泵集式密封的大(da)多(duo)數主要特性是(shi)其控(kong)制(zhi)密封功能、摩(mo)(mo)擦力(li)(li)、磨(mo)損和(he)壽命的自動界面(mian)潤(run)滑機理(li)。一切(qie)取(qu)決于穿過界面(mian)并建立(li)潤(run)滑膜的液體以便密封在(zai)實際無接觸(chu),通常是(shi)混(hun)合(he)磨(mo)擦,介(jie)于干摩(mo)(mo)擦和(he)完(wan)整液膜之間(jian)的潤(run)滑摩(mo)(mo)擦狀態下運(yun)行。在(zai)腔(qiang)體壓(ya)力(li)(li)作(zuo)用(yong)下介(jie)質穿過密封摩(mo)(mo)擦副(fu)端(duan)面(mian),表(biao)面(mian)張力(li)(li)和(he)離心力(li)(li)在(zai)此時(shi)影響不大(da),流(liu)體壓(ya)力(li)(li)持續下降直到(dao)它達到(dao)外部背壓(ya),此壓(ya)力(li)(li)作(zuo)用(yong)類(lei)似于流(liu)體靜壓(ya)時(shi)軸承(cheng)的承(cheng)載功能。這取(qu)決于介(jie)質粘度、轉速和(he)端(duan)面(mian)間(jian)隙變化。
