在研磨過程中，閥門制造的密封面是一個常用的整理方法，可以使龍江機械密封摩擦端面(mian)(mian)尺寸精(jing)度提(ti)高(gao)，閥(fa)門(men)的密(mi)封面(mian)(mian)，幾何(he)粗糙(cao)度和(he)表(biao)面(mian)(mian)粗糙(cao)度，但不能提(ti)高(gao)密(mi)封表(biao)面(mian)(mian)的相(xiang)互位置(zhi)精(jing)度。

　　龍江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，隨著對龍江機械密封研(yan)(yan)(yan)究(jiu)的(de)(de)(de)(de)(de)復雜(za)面(mian)(mian)，之間(jian)的(de)(de)(de)(de)(de)表(biao)(biao)面(mian)(mian)和(he)(he)(he)密(mi)(mi)封(feng)磨(mo)料磨(mo)具(ju)研(yan)(yan)(yan)究(jiu)相(xiang)對(dui)運(yun)(yun)動(dong)時(shi)，密(mi)(mi)封(feng)圈表(biao)(biao)面(mian)(mian)，磨(mo)料磨(mo)具(ju)研(yan)(yan)(yan)究(jiu)部(bu)分(fen)和(he)(he)(he)密(mi)(mi)封(feng)面(mian)(mian)之間(jian)的(de)(de)(de)(de)(de)滑(hua)動(dong)或(huo)滾(gun)動(dong)，切斷密(mi)(mi)封(feng)圈上薄(bo)薄(bo)的(de)(de)(de)(de)(de)一(yi)層(ceng)金(jin)屬表(biao)(biao)面(mian)(mian)。密(mi)(mi)封(feng)凸峰部(bu)分(fen)的(de)(de)(de)(de)(de)圈，表(biao)(biao)面(mian)(mian)研(yan)(yan)(yan)磨(mo)，然(ran)后逐漸(jian)達到所要求的(de)(de)(de)(de)(de)幾何形狀。不(bu)僅是(shi)金(jin)屬磨(mo)料的(de)(de)(de)(de)(de)研(yan)(yan)(yan)磨(mo)加工，以及化(hua)學作用。研(yan)(yan)(yan)磨(mo)油(you)可使(shi)加工表(biao)(biao)面(mian)(mian)形成的(de)(de)(de)(de)(de)氧化(hua)膜，從(cong)而(er)加快研(yan)(yan)(yan)磨(mo)過程。地面(mian)(mian)運(yun)(yun)動(dong)相(xiang)對(dui)運(yun)(yun)動(dong)的(de)(de)(de)(de)(de)表(biao)(biao)面(mian)(mian)和(he)(he)(he)密(mi)(mi)封(feng)圈密(mi)(mi)封(feng)圈的(de)(de)(de)(de)(de)研(yan)(yan)(yan)究(jiu)，對(dui)每個點(dian)的(de)(de)(de)(de)(de)表(biao)(biao)面(mian)(mian)上的(de)(de)(de)(de)(de)道路(lu)和(he)(he)(he)相(xiang)對(dui)滑(hua)動(dong)的(de)(de)(de)(de)(de)研(yan)(yan)(yan)究(jiu)應該是(shi)一(yi)樣(yang)的(de)(de)(de)(de)(de)。和(he)(he)(he)相(xiang)對(dui)運(yun)(yun)動(dong)方(fang)向改變。改變密(mi)(mi)封(feng)環內的(de)(de)(de)(de)(de)每個粒子的(de)(de)(de)(de)(de)表(biao)(biao)面(mian)(mian)上運(yun)(yun)動(dong)的(de)(de)(de)(de)(de)方(fang)向不(bu)會重(zhong)復他們的(de)(de)(de)(de)(de)軌跡(ji)，以避免磨(mo)損明顯(xian)增加了(le)密(mi)(mi)封(feng)環的(de)(de)(de)(de)(de)表(biao)(biao)面(mian)(mian)粗(cu)糙度。此外，運(yun)(yun)動(dong)方(fang)向的(de)(de)(de)(de)(de)改變不(bu)能使(shi)磨(mo)粒分(fen)布比較均勻(yun)(yun)，且均勻(yun)(yun)切斷金(jin)屬密(mi)(mi)封(feng)環的(de)(de)(de)(de)(de)表(biao)(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龍江機械密封將熱量(liang)傳給軸承，使軸承溫度(du)升高。為了控制傳熱，所(suo)以密封的水也起到冷卻作(zuo)用(yong)。

　　龍江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龍江機械密封低(di)壓(ya)側(大氣)將清水、蒸(zheng)汽(qi)等(deng)(deng)冷卻流(liu)(liu)體(ti)直接引入密封端泄(xie)露處的(de)一種冷卻方式，也稱(cheng)急(ji)(ji)冷，急(ji)(ji)冷不僅冷卻*，還能(neng)將密封端面(mian)周圍的(de)雜質及泄(xie)露液帶走(zou)，急(ji)(ji)冷液其壓(ya)力比(bi)密封介質壓(ya)力低(di)。急(ji)(ji)冷液應盡量采用(yong)軟水，以防(fang)止水垢(gou)產生破壞密封端面(mian)。當(dang)密封流(liu)(liu)體(ti)為(wei)易(yi)凝固、易(yi)結晶時(shi)，可(ke)用(yong)蒸(zheng)汽(qi)、溶劑等(deng)(deng)防(fang)止流(liu)(liu)體(ti)凝結。
