　　熱(re)水(shui)泵集(ji)式密封(feng)要(yao)起(qi)到(dao)靜環(huan)(huan)(huan)和動(dong)(dong)(dong)(dong)(dong)環(huan)(huan)(huan)的(de)(de)密封(feng)作用，同時(shi)也起(qi)到(dao)浮動(dong)(dong)(dong)(dong)(dong)緩沖作用，要(yao)求靜環(huan)(huan)(huan)的(de)(de)輔(fu)助(zhu)密封(feng)元件(jian)能(neng)(neng)保證(zheng)靜環(huan)(huan)(huan)與壓(ya)蓋之間(jian)的(de)(de)密封(feng)性(xing)和靜環(huan)(huan)(huan)有一定(ding)的(de)(de)浮動(dong)(dong)(dong)(dong)(dong)性(xing)，動(dong)(dong)(dong)(dong)(dong)環(huan)(huan)(huan)的(de)(de)輔(fu)助(zhu)密封(feng)元件(jian)能(neng)(neng)保證(zheng)動(dong)(dong)(dong)(dong)(dong)環(huan)(huan)(huan)與軸與軸套之間(jian)的(de)(de)密封(feng)性(xing)和動(dong)(dong)(dong)(dong)(dong)環(huan)(huan)(huan)的(de)(de)浮動(dong)(dong)(dong)(dong)(dong)性(xing)，材料要(yao)求耐熱(re)或耐寒(han)并能(neng)(neng)與介(jie)質相容。起(qi)到(dao)將軸的(de)(de)轉矩(ju)傳(chuan)(chuan)給動(dong)(dong)(dong)(dong)(dong)環(huan)(huan)(huan)的(de)(de)作用，中間(jian)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)的(de)(de)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)銷、壓(ya)環(huan)(huan)(huan)—傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)環(huan)(huan)(huan)、傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)銷—彈簧座均起(qi)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)作用，材料要(yao)求耐磨和耐腐(fu)蝕。

　　緊固(gu)件要起到(dao)靜(jing)、動環的定位(wei)、緊固(gu)和(he)盛裝(zhuang)的作用，要求定位(wei)正確(que)，保(bao)證摩(mo)擦副密封面(mian)處于正確(que)的位(wei)置并保(bao)持良好貼(tie)合的彈(dan)簧比(bi)壓。同時要求拆裝(zhuang)方便、容易就位(wei)、能重復利用。與輔助密封配合處，注意安裝(zhuang)密封環的導向側角(jiao)和(he)壓彈(dan)量。特(te)別(bie)應注意動環輔助密封件與軸(zhou)套(tao)配合處要求耐(nai)腐蝕和(he)耐(nai)磨損，必要時采用硬面(mian)復層。

　　熱水泵集式密封(feng)一般配(pei)上平衡循環(huan)(huan)系統，可使(shi)用(yong)在易(yi)燃、易(yi)爆、有毒(du)及腐蝕、高(gao)真(zhen)空等對密封(feng)要求(qiu)更為嚴格的(de)場合(he)。密封(feng)結構為外(wai)沖(chong)洗(xi)(xi)結構，沖(chong)洗(xi)(xi)液(ye)可以為清(qing)潔的(de)水也可為工業回用(yong)水，密封(feng)腔壓力(li)高(gao)于(yu)沖(chong)洗(xi)(xi)液(ye)的(de)壓力(li)，沖(chong)洗(xi)(xi)液(ye)在輔助套的(de)上端輸(shu)入，在輔助套的(de)下端輸(shu)出,循環(huan)(huan)使(shi)用(yong),密封(feng)起(qi)到冷卻沖(chong)洗(xi)(xi)的(de)作用(yong)，其(qi)輔助裝置有調溫器、平衡罐、強制循環(huan)(huan)平衡系統等。
