熱(re)水泵集式密封(feng)的大多(duo)數主要(yao)特性(xing)是其控制(zhi)密封(feng)功能、摩(mo)(mo)擦力(li)、磨(mo)損(sun)和壽命的自動界(jie)面(mian)(mian)(mian)潤滑(hua)機理。一切取決(jue)于穿(chuan)過界(jie)面(mian)(mian)(mian)并(bing)建立潤滑(hua)膜(mo)的液體以便(bian)密封(feng)在實際無接觸，通(tong)常是混(hun)合磨(mo)擦，介(jie)(jie)于干摩(mo)(mo)擦和完整(zheng)液膜(mo)之間(jian)的潤滑(hua)摩(mo)(mo)擦狀態下(xia)運行。在腔體壓力(li)作用下(xia)介(jie)(jie)質(zhi)穿(chuan)過密封(feng)摩(mo)(mo)擦副端面(mian)(mian)(mian)，表面(mian)(mian)(mian)張力(li)和離心(xin)力(li)在此時影響不大，流體壓力(li)持(chi)續下(xia)降直到它達到外部(bu)背壓，此壓力(li)作用類似于流體靜壓時軸承的承載功能。這取決(jue)于介(jie)(jie)質(zhi)粘度、轉(zhuan)速和端面(mian)(mian)(mian)間(jian)隙變化。
