在研磨過程中，閥門制造的密封面是一個常用的整理方法，可以使隆子機械密封摩(mo)擦端面尺寸精度提高，閥門(men)的密封面，幾何粗糙(cao)度和(he)表面粗糙(cao)度，但不能提高密封表面的相互位置精度。

　　隆子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，隨著對隆子機械密封研(yan)(yan)究的(de)(de)(de)(de)(de)(de)(de)(de)復(fu)雜面(mian)，之(zhi)間的(de)(de)(de)(de)(de)(de)(de)(de)表(biao)(biao)(biao)(biao)(biao)面(mian)和(he)(he)密(mi)(mi)封(feng)(feng)磨(mo)(mo)(mo)(mo)(mo)料磨(mo)(mo)(mo)(mo)(mo)具研(yan)(yan)究相(xiang)對運(yun)動(dong)(dong)(dong)時，密(mi)(mi)封(feng)(feng)圈(quan)表(biao)(biao)(biao)(biao)(biao)面(mian)，磨(mo)(mo)(mo)(mo)(mo)料磨(mo)(mo)(mo)(mo)(mo)具研(yan)(yan)究部(bu)分(fen)和(he)(he)密(mi)(mi)封(feng)(feng)面(mian)之(zhi)間的(de)(de)(de)(de)(de)(de)(de)(de)滑動(dong)(dong)(dong)或滾動(dong)(dong)(dong)，切斷密(mi)(mi)封(feng)(feng)圈(quan)上薄(bo)薄(bo)的(de)(de)(de)(de)(de)(de)(de)(de)一層金屬表(biao)(biao)(biao)(biao)(biao)面(mian)。密(mi)(mi)封(feng)(feng)凸峰(feng)部(bu)分(fen)的(de)(de)(de)(de)(de)(de)(de)(de)圈(quan)，表(biao)(biao)(biao)(biao)(biao)面(mian)研(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)，然后(hou)逐(zhu)漸達(da)到所要求的(de)(de)(de)(de)(de)(de)(de)(de)幾何形(xing)狀。不僅是金屬磨(mo)(mo)(mo)(mo)(mo)料的(de)(de)(de)(de)(de)(de)(de)(de)研(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)加工(gong)，以(yi)及化(hua)學作(zuo)用。研(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)油(you)可使加工(gong)表(biao)(biao)(biao)(biao)(biao)面(mian)形(xing)成的(de)(de)(de)(de)(de)(de)(de)(de)氧化(hua)膜(mo)，從而(er)加快研(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)過程。地面(mian)運(yun)動(dong)(dong)(dong)相(xiang)對運(yun)動(dong)(dong)(dong)的(de)(de)(de)(de)(de)(de)(de)(de)表(biao)(biao)(biao)(biao)(biao)面(mian)和(he)(he)密(mi)(mi)封(feng)(feng)圈(quan)密(mi)(mi)封(feng)(feng)圈(quan)的(de)(de)(de)(de)(de)(de)(de)(de)研(yan)(yan)究，對每(mei)個(ge)點的(de)(de)(de)(de)(de)(de)(de)(de)表(biao)(biao)(biao)(biao)(biao)面(mian)上的(de)(de)(de)(de)(de)(de)(de)(de)道路和(he)(he)相(xiang)對滑動(dong)(dong)(dong)的(de)(de)(de)(de)(de)(de)(de)(de)研(yan)(yan)究應(ying)該是一樣的(de)(de)(de)(de)(de)(de)(de)(de)。和(he)(he)相(xiang)對運(yun)動(dong)(dong)(dong)方(fang)向(xiang)改變。改變密(mi)(mi)封(feng)(feng)環(huan)(huan)內的(de)(de)(de)(de)(de)(de)(de)(de)每(mei)個(ge)粒(li)子的(de)(de)(de)(de)(de)(de)(de)(de)表(biao)(biao)(biao)(biao)(biao)面(mian)上運(yun)動(dong)(dong)(dong)的(de)(de)(de)(de)(de)(de)(de)(de)方(fang)向(xiang)不會(hui)重復(fu)他們的(de)(de)(de)(de)(de)(de)(de)(de)軌跡，以(yi)避免(mian)磨(mo)(mo)(mo)(mo)(mo)損明顯增加了密(mi)(mi)封(feng)(feng)環(huan)(huan)的(de)(de)(de)(de)(de)(de)(de)(de)表(biao)(biao)(biao)(biao)(biao)面(mian)粗糙度。此外(wai)，運(yun)動(dong)(dong)(dong)方(fang)向(xiang)的(de)(de)(de)(de)(de)(de)(de)(de)改變不能使磨(mo)(mo)(mo)(mo)(mo)粒(li)分(fen)布比較均勻(yun)，且均勻(yun)切斷金屬密(mi)(mi)封(feng)(feng)環(huan)(huan)的(de)(de)(de)(de)(de)(de)(de)(de)表(biao)(biao)(biao)(biao)(biao)面(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隆子機械密封將熱量(liang)傳給軸承，使軸承溫(wen)度升高。為了(le)控制傳熱，所以密封的水也起到(dao)冷卻(que)作用。

　　隆子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隆子機械密封低(di)壓(ya)(ya)側(ce)(大氣)將清水、蒸汽(qi)等冷卻流(liu)(liu)體(ti)(ti)直接引入密(mi)(mi)(mi)封(feng)端(duan)(duan)泄(xie)(xie)露處的(de)一種(zhong)冷卻方(fang)式，也稱急(ji)冷，急(ji)冷不僅冷卻*，還能將密(mi)(mi)(mi)封(feng)端(duan)(duan)面周圍的(de)雜質(zhi)及泄(xie)(xie)露液帶走，急(ji)冷液其壓(ya)(ya)力比(bi)密(mi)(mi)(mi)封(feng)介質(zhi)壓(ya)(ya)力低(di)。急(ji)冷液應盡量(liang)采用軟水，以防止水垢產生破(po)壞密(mi)(mi)(mi)封(feng)端(duan)(duan)面。當密(mi)(mi)(mi)封(feng)流(liu)(liu)體(ti)(ti)為易凝固、易結(jie)晶時，可用蒸汽(qi)、溶劑等防止流(liu)(liu)體(ti)(ti)凝結(jie)。
