在研磨過程中，閥門制造的密封面是一個常用的整理方法，可以使雙流機械密封摩擦端面(mian)尺寸精(jing)度(du)提(ti)高(gao)(gao)，閥(fa)門的密封面(mian)，幾何粗糙(cao)度(du)和(he)表(biao)(biao)面(mian)粗糙(cao)度(du)，但不能提(ti)高(gao)(gao)密封表(biao)(biao)面(mian)的相(xiang)互位置精(jing)度(du)。

　　雙流機械密封面研磨包括五個方面的基本原理：研磨運動、研磨工藝、研磨速度、研磨壓力和研磨余量。研磨過程好一起研究密封面，隨著對雙流機械密封研究(jiu)(jiu)的(de)(de)(de)(de)(de)復雜面(mian)(mian)，之(zhi)間的(de)(de)(de)(de)(de)表面(mian)(mian)和(he)(he)密(mi)封磨(mo)料(liao)(liao)磨(mo)具(ju)研究(jiu)(jiu)相對(dui)(dui)運動(dong)(dong)時，密(mi)封圈(quan)(quan)表面(mian)(mian)，磨(mo)料(liao)(liao)磨(mo)具(ju)研究(jiu)(jiu)部分和(he)(he)密(mi)封面(mian)(mian)之(zhi)間的(de)(de)(de)(de)(de)滑動(dong)(dong)或(huo)滾動(dong)(dong)，切(qie)斷(duan)密(mi)封圈(quan)(quan)上(shang)薄薄的(de)(de)(de)(de)(de)一(yi)層金(jin)(jin)屬(shu)表面(mian)(mian)。密(mi)封凸峰(feng)部分的(de)(de)(de)(de)(de)圈(quan)(quan)，表面(mian)(mian)研磨(mo)，然(ran)后逐漸達到所要求的(de)(de)(de)(de)(de)幾(ji)何形狀。不(bu)僅(jin)是金(jin)(jin)屬(shu)磨(mo)料(liao)(liao)的(de)(de)(de)(de)(de)研磨(mo)加(jia)(jia)工，以(yi)及化學作(zuo)用。研磨(mo)油可使加(jia)(jia)工表面(mian)(mian)形成的(de)(de)(de)(de)(de)氧化膜，從而加(jia)(jia)快研磨(mo)過(guo)程。地面(mian)(mian)運動(dong)(dong)相對(dui)(dui)運動(dong)(dong)的(de)(de)(de)(de)(de)表面(mian)(mian)和(he)(he)密(mi)封圈(quan)(quan)密(mi)封圈(quan)(quan)的(de)(de)(de)(de)(de)研究(jiu)(jiu)，對(dui)(dui)每個點的(de)(de)(de)(de)(de)表面(mian)(mian)上(shang)的(de)(de)(de)(de)(de)道路和(he)(he)相對(dui)(dui)滑動(dong)(dong)的(de)(de)(de)(de)(de)研究(jiu)(jiu)應該是一(yi)樣(yang)的(de)(de)(de)(de)(de)。和(he)(he)相對(dui)(dui)運動(dong)(dong)方(fang)向改(gai)(gai)變。改(gai)(gai)變密(mi)封環(huan)內的(de)(de)(de)(de)(de)每個粒子的(de)(de)(de)(de)(de)表面(mian)(mian)上(shang)運動(dong)(dong)的(de)(de)(de)(de)(de)方(fang)向不(bu)會重復他們的(de)(de)(de)(de)(de)軌跡，以(yi)避免(mian)磨(mo)損明顯增加(jia)(jia)了(le)密(mi)封環(huan)的(de)(de)(de)(de)(de)表面(mian)(mian)粗糙度。此外，運動(dong)(dong)方(fang)向的(de)(de)(de)(de)(de)改(gai)(gai)變不(bu)能使磨(mo)粒分布比較均(jun)勻，且均(jun)勻切(qie)斷(duan)金(jin)(jin)屬(shu)密(mi)封環(huan)的(de)(de)(de)(de)(de)表面(mian)(mian)。

　　為了不讓泵水通過軸與密封間隙泄漏，由出口冷凝泵或在鹽水中的母管引至密封水。給水泵是一種具有一定溫度、高溫的水通過泵軸或泵體金屬容器用雙流機械密封將熱量(liang)傳(chuan)給(gei)軸承，使(shi)軸承溫度升(sheng)高。為了控(kong)制傳(chuan)熱，所以(yi)密封(feng)的水也起到(dao)冷卻作用。

　　雙流機械密封直接冷卻就是冷卻液體直接和密封端面接觸達到冷卻的目的。沖洗實際上也是直接冷卻的一種方式，沖洗方式中通過管路連接換熱器將冷卻后的沖洗液引入密封腔進行直接冷卻。還有一種直接冷卻就是在雙流機械密封低壓側(大氣(qi))將清水、蒸(zheng)汽(qi)等冷(leng)(leng)卻(que)流(liu)體直(zhi)接引入密封端(duan)泄露(lu)處的一種(zhong)冷(leng)(leng)卻(que)方式，也稱急冷(leng)(leng)，急冷(leng)(leng)不僅冷(leng)(leng)卻(que)*，還(huan)能(neng)將密封端(duan)面周圍的雜(za)質及(ji)泄露(lu)液帶走，急冷(leng)(leng)液其(qi)壓力比(bi)密封介質壓力低。急冷(leng)(leng)液應盡量(liang)采用(yong)軟水，以(yi)防止(zhi)水垢產(chan)生破壞密封端(duan)面。當密封流(liu)體為易凝(ning)固、易結晶時，可(ke)用(yong)蒸(zheng)汽(qi)、溶(rong)劑(ji)等防止(zhi)流(liu)體凝(ning)結。
