在研磨過程中，閥門制造的密封面是一個常用的整理方法，可以使瑪多機械密封摩擦(ca)端(duan)面(mian)(mian)(mian)尺寸(cun)精度提(ti)高(gao)，閥門的(de)密封面(mian)(mian)(mian)，幾何粗糙度和表面(mian)(mian)(mian)粗糙度，但(dan)不能提(ti)高(gao)密封表面(mian)(mian)(mian)的(de)相(xiang)互(hu)位置精度。

　　瑪多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，隨著對瑪多機械密封研究(jiu)(jiu)的(de)(de)(de)(de)復雜(za)面(mian)(mian)，之間的(de)(de)(de)(de)表(biao)面(mian)(mian)和(he)(he)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)磨(mo)(mo)料(liao)(liao)磨(mo)(mo)具研究(jiu)(jiu)相對(dui)運(yun)(yun)動(dong)時，密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)圈(quan)表(biao)面(mian)(mian)，磨(mo)(mo)料(liao)(liao)磨(mo)(mo)具研究(jiu)(jiu)部(bu)分和(he)(he)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)面(mian)(mian)之間的(de)(de)(de)(de)滑(hua)動(dong)或滾(gun)動(dong)，切(qie)(qie)斷密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)圈(quan)上(shang)薄薄的(de)(de)(de)(de)一層金屬表(biao)面(mian)(mian)。密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)凸(tu)峰部(bu)分的(de)(de)(de)(de)圈(quan)，表(biao)面(mian)(mian)研磨(mo)(mo)，然后(hou)逐(zhu)漸(jian)達到所要求的(de)(de)(de)(de)幾何形狀。不(bu)(bu)僅是金屬磨(mo)(mo)料(liao)(liao)的(de)(de)(de)(de)研磨(mo)(mo)加工(gong)，以及(ji)化學作用。研磨(mo)(mo)油(you)可使(shi)加工(gong)表(biao)面(mian)(mian)形成的(de)(de)(de)(de)氧化膜(mo)，從而(er)加快研磨(mo)(mo)過程。地面(mian)(mian)運(yun)(yun)動(dong)相對(dui)運(yun)(yun)動(dong)的(de)(de)(de)(de)表(biao)面(mian)(mian)和(he)(he)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)圈(quan)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)圈(quan)的(de)(de)(de)(de)研究(jiu)(jiu)，對(dui)每(mei)個(ge)點的(de)(de)(de)(de)表(biao)面(mian)(mian)上(shang)的(de)(de)(de)(de)道路和(he)(he)相對(dui)滑(hua)動(dong)的(de)(de)(de)(de)研究(jiu)(jiu)應該是一樣的(de)(de)(de)(de)。和(he)(he)相對(dui)運(yun)(yun)動(dong)方(fang)向改(gai)變(bian)。改(gai)變(bian)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)環內(nei)的(de)(de)(de)(de)每(mei)個(ge)粒(li)子的(de)(de)(de)(de)表(biao)面(mian)(mian)上(shang)運(yun)(yun)動(dong)的(de)(de)(de)(de)方(fang)向不(bu)(bu)會重(zhong)復他們的(de)(de)(de)(de)軌跡(ji)，以避免磨(mo)(mo)損明顯增加了密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)環的(de)(de)(de)(de)表(biao)面(mian)(mian)粗糙度(du)。此外(wai)，運(yun)(yun)動(dong)方(fang)向的(de)(de)(de)(de)改(gai)變(bian)不(bu)(bu)能使(shi)磨(mo)(mo)粒(li)分布比較均勻，且均勻切(qie)(qie)斷金屬密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)環的(de)(de)(de)(de)表(biao)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瑪多機械密封將熱量傳給軸承(cheng)，使(shi)軸承(cheng)溫度升高。為了控制傳熱，所以密封(feng)的水也起到(dao)冷(leng)卻(que)作用(yong)。

　　瑪多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瑪多機械密封低壓側(ce)(大氣(qi))將清水(shui)、蒸(zheng)(zheng)汽(qi)等(deng)(deng)冷卻流體直(zhi)接引入密(mi)(mi)封(feng)端泄(xie)露處(chu)的一種冷卻方式，也稱急(ji)冷，急(ji)冷不(bu)僅冷卻*，還能(neng)將密(mi)(mi)封(feng)端面周(zhou)圍的雜質及泄(xie)露液(ye)帶(dai)走，急(ji)冷液(ye)其壓力比密(mi)(mi)封(feng)介質壓力低。急(ji)冷液(ye)應(ying)盡量采用軟水(shui)，以(yi)防止水(shui)垢產(chan)生破壞密(mi)(mi)封(feng)端面。當密(mi)(mi)封(feng)流體為易凝固、易結(jie)晶(jing)時，可用蒸(zheng)(zheng)汽(qi)、溶劑等(deng)(deng)防止流體凝結(jie)。
