在研磨過程中，閥門制造的密封面是一個常用的整理方法，可以使潁州機械密封摩擦端面(mian)尺寸精度(du)提高(gao)，閥門的(de)密(mi)封面(mian)，幾何粗糙度(du)和表面(mian)粗糙度(du)，但(dan)不(bu)能提高(gao)密(mi)封表面(mian)的(de)相(xiang)互位置精度(du)。

　　潁州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，隨著對潁州機械密封研(yan)究的(de)(de)(de)(de)(de)(de)復雜面(mian)(mian)，之間(jian)的(de)(de)(de)(de)(de)(de)表(biao)面(mian)(mian)和(he)(he)(he)密(mi)封(feng)磨(mo)(mo)料(liao)磨(mo)(mo)具研(yan)究相對運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)時，密(mi)封(feng)圈(quan)表(biao)面(mian)(mian)，磨(mo)(mo)料(liao)磨(mo)(mo)具研(yan)究部分(fen)和(he)(he)(he)密(mi)封(feng)面(mian)(mian)之間(jian)的(de)(de)(de)(de)(de)(de)滑動(dong)(dong)(dong)(dong)(dong)或滾(gun)動(dong)(dong)(dong)(dong)(dong)，切(qie)斷密(mi)封(feng)圈(quan)上(shang)薄薄的(de)(de)(de)(de)(de)(de)一(yi)層金屬表(biao)面(mian)(mian)。密(mi)封(feng)凸(tu)峰(feng)部分(fen)的(de)(de)(de)(de)(de)(de)圈(quan)，表(biao)面(mian)(mian)研(yan)磨(mo)(mo)，然后逐(zhu)漸達到所要求的(de)(de)(de)(de)(de)(de)幾何(he)形(xing)狀。不僅是金屬磨(mo)(mo)料(liao)的(de)(de)(de)(de)(de)(de)研(yan)磨(mo)(mo)加(jia)工，以及化學作(zuo)用(yong)。研(yan)磨(mo)(mo)油可使加(jia)工表(biao)面(mian)(mian)形(xing)成的(de)(de)(de)(de)(de)(de)氧化膜，從(cong)而(er)加(jia)快(kuai)研(yan)磨(mo)(mo)過程。地面(mian)(mian)運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)相對運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)(de)(de)(de)表(biao)面(mian)(mian)和(he)(he)(he)密(mi)封(feng)圈(quan)密(mi)封(feng)圈(quan)的(de)(de)(de)(de)(de)(de)研(yan)究，對每(mei)個點的(de)(de)(de)(de)(de)(de)表(biao)面(mian)(mian)上(shang)的(de)(de)(de)(de)(de)(de)道路和(he)(he)(he)相對滑動(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)(de)(de)(de)研(yan)究應該是一(yi)樣的(de)(de)(de)(de)(de)(de)。和(he)(he)(he)相對運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)方向改變。改變密(mi)封(feng)環(huan)內的(de)(de)(de)(de)(de)(de)每(mei)個粒子的(de)(de)(de)(de)(de)(de)表(biao)面(mian)(mian)上(shang)運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)(de)(de)(de)方向不會重復他們(men)的(de)(de)(de)(de)(de)(de)軌跡(ji)，以避免磨(mo)(mo)損明顯增加(jia)了密(mi)封(feng)環(huan)的(de)(de)(de)(de)(de)(de)表(biao)面(mian)(mian)粗糙度。此外，運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)方向的(de)(de)(de)(de)(de)(de)改變不能使磨(mo)(mo)粒分(fen)布(bu)比(bi)較均(jun)(jun)勻，且(qie)均(jun)(jun)勻切(qie)斷金屬密(mi)封(feng)環(huan)的(de)(de)(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潁州機械密封將熱量傳(chuan)給軸(zhou)承(cheng)，使軸(zhou)承(cheng)溫度(du)升高(gao)。為了控制(zhi)傳(chuan)熱，所以密封的(de)水(shui)也(ye)起(qi)到冷卻作用。

　　潁州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潁州機械密封低壓側(ce)(大氣)將清(qing)水、蒸汽(qi)等冷卻(que)流體(ti)直接引入(ru)密封(feng)端泄(xie)(xie)露處的(de)一種冷卻(que)方(fang)式，也稱急冷，急冷不僅冷卻(que)*，還能將密封(feng)端面周圍的(de)雜質及泄(xie)(xie)露液(ye)(ye)帶(dai)走，急冷液(ye)(ye)其壓力比密封(feng)介質壓力低。急冷液(ye)(ye)應盡(jin)量采用(yong)軟水，以防止水垢產(chan)生破壞密封(feng)端面。當密封(feng)流體(ti)為(wei)易凝(ning)固、易結(jie)晶時，可用(yong)蒸汽(qi)、溶劑等防止流體(ti)凝(ning)結(jie)。
