熱水泵集式密封的(de)大(da)多數(shu)主要特性是其控制密封功能、摩(mo)擦(ca)力、磨(mo)損和壽命(ming)的(de)自動(dong)界面(mian)潤滑(hua)(hua)機理(li)。一切取(qu)決于穿(chuan)過界面(mian)并建立(li)潤滑(hua)(hua)膜的(de)液(ye)體(ti)以便密封在實際無接觸，通常(chang)是混合磨(mo)擦(ca)，介于干摩(mo)擦(ca)和完整液(ye)膜之間(jian)的(de)潤滑(hua)(hua)摩(mo)擦(ca)狀(zhuang)態下運行。在腔體(ti)壓力作用下介質穿(chuan)過密封摩(mo)擦(ca)副端面(mian)，表(biao)面(mian)張(zhang)力和離心力在此(ci)時(shi)影響不大(da)，流(liu)體(ti)壓力持續下降(jiang)直(zhi)到它(ta)達到外部背壓，此(ci)壓力作用類似于流(liu)體(ti)靜壓時(shi)軸承的(de)承載(zai)功能。這取(qu)決于介質粘(zhan)度、轉速和端面(mian)間(jian)隙變(bian)化(hua)。

　　熱(re)水泵集式密(mi)封(feng)要(yao)起到(dao)靜環(huan)(huan)和(he)動(dong)(dong)(dong)(dong)(dong)環(huan)(huan)的(de)密(mi)封(feng)作用，同時也(ye)起到(dao)浮(fu)動(dong)(dong)(dong)(dong)(dong)緩(huan)沖(chong)作用，要(yao)求靜環(huan)(huan)的(de)輔助密(mi)封(feng)元件能保證靜環(huan)(huan)與(yu)壓蓋之(zhi)間(jian)的(de)密(mi)封(feng)性(xing)和(he)靜環(huan)(huan)有一(yi)定的(de)浮(fu)動(dong)(dong)(dong)(dong)(dong)性(xing)，動(dong)(dong)(dong)(dong)(dong)環(huan)(huan)的(de)輔助密(mi)封(feng)元件能保證動(dong)(dong)(dong)(dong)(dong)環(huan)(huan)與(yu)軸與(yu)軸套之(zhi)間(jian)的(de)密(mi)封(feng)性(xing)和(he)動(dong)(dong)(dong)(dong)(dong)環(huan)(huan)的(de)浮(fu)動(dong)(dong)(dong)(dong)(dong)性(xing)，材(cai)料要(yao)求耐(nai)熱(re)或(huo)耐(nai)寒(han)并(bing)能與(yu)介(jie)質相容。起到(dao)將軸的(de)轉(zhuan)矩傳(chuan)(chuan)給動(dong)(dong)(dong)(dong)(dong)環(huan)(huan)的(de)作用，中間(jian)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)銷、壓環(huan)(huan)—傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)環(huan)(huan)、傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)銷—彈簧座均起傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)作用，材(cai)料要(yao)求耐(nai)磨和(he)耐(nai)腐蝕。

　　緊(jin)固(gu)件要起到靜、動(dong)環的定(ding)位、緊(jin)固(gu)和(he)盛裝的作用，要求(qiu)定(ding)位正確(que)，保(bao)證摩擦副密(mi)(mi)封(feng)面處于(yu)正確(que)的位置(zhi)并保(bao)持良好貼合(he)的彈簧比壓(ya)。同時要求(qiu)拆裝方便、容易(yi)就位、能重(zhong)復利(li)用。與輔(fu)助密(mi)(mi)封(feng)配(pei)合(he)處，注意安裝密(mi)(mi)封(feng)環的導向側角和(he)壓(ya)彈量。特別應注意動(dong)環輔(fu)助密(mi)(mi)封(feng)件與軸套配(pei)合(he)處要求(qiu)耐腐蝕和(he)耐磨損，必要時采用硬面復層。

　　熱水(shui)泵集式密封一般配上平衡(heng)循環系統(tong)，可使用在易(yi)燃、易(yi)爆(bao)、有毒及腐(fu)蝕、高真空等對(dui)密封要(yao)求(qiu)更為嚴格的場合。密封結構為外沖(chong)洗結構，沖(chong)洗液可以為清潔的水(shui)也可為工(gong)業回用水(shui)，密封腔壓力高于沖(chong)洗液的壓力，沖(chong)洗液在輔助套的上端輸入，在輔助套的下端輸出,循環使用,密封起到冷卻沖(chong)洗的作用，其輔助裝置有調(diao)溫器(qi)、平衡(heng)罐(guan)、強制循環平衡(heng)系統(tong)等。
