在研磨過程中，閥門制造的密封面是一個常用的整理方法，可以使定襄機械密封摩(mo)擦端(duan)面(mian)尺寸(cun)精(jing)度(du)提高(gao)，閥門(men)的(de)密封(feng)(feng)面(mian)，幾何粗糙(cao)度(du)和表面(mian)粗糙(cao)度(du)，但不能提高(gao)密封(feng)(feng)表面(mian)的(de)相互位置(zhi)精(jing)度(du)。

　　定襄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，隨著對定襄機械密封研(yan)究的(de)(de)(de)(de)(de)復雜面，之間(jian)的(de)(de)(de)(de)(de)表(biao)(biao)(biao)面和(he)密(mi)封磨(mo)(mo)(mo)料(liao)磨(mo)(mo)(mo)具研(yan)究相對運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)時，密(mi)封圈表(biao)(biao)(biao)面，磨(mo)(mo)(mo)料(liao)磨(mo)(mo)(mo)具研(yan)究部分和(he)密(mi)封面之間(jian)的(de)(de)(de)(de)(de)滑動(dong)(dong)(dong)(dong)或滾動(dong)(dong)(dong)(dong)，切(qie)斷(duan)密(mi)封圈上薄薄的(de)(de)(de)(de)(de)一(yi)層金屬表(biao)(biao)(biao)面。密(mi)封凸峰部分的(de)(de)(de)(de)(de)圈，表(biao)(biao)(biao)面研(yan)磨(mo)(mo)(mo)，然后逐漸達(da)到所(suo)要求的(de)(de)(de)(de)(de)幾何形(xing)狀。不(bu)僅是(shi)金屬磨(mo)(mo)(mo)料(liao)的(de)(de)(de)(de)(de)研(yan)磨(mo)(mo)(mo)加(jia)工，以(yi)及化學(xue)作用。研(yan)磨(mo)(mo)(mo)油可使(shi)加(jia)工表(biao)(biao)(biao)面形(xing)成的(de)(de)(de)(de)(de)氧化膜，從(cong)而加(jia)快研(yan)磨(mo)(mo)(mo)過程。地面運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)相對運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)的(de)(de)(de)(de)(de)表(biao)(biao)(biao)面和(he)密(mi)封圈密(mi)封圈的(de)(de)(de)(de)(de)研(yan)究，對每個點的(de)(de)(de)(de)(de)表(biao)(biao)(biao)面上的(de)(de)(de)(de)(de)道(dao)路和(he)相對滑動(dong)(dong)(dong)(dong)的(de)(de)(de)(de)(de)研(yan)究應該(gai)是(shi)一(yi)樣(yang)的(de)(de)(de)(de)(de)。和(he)相對運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)方(fang)向(xiang)改(gai)變。改(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(biao)(biao)(biao)面上運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)的(de)(de)(de)(de)(de)方(fang)向(xiang)不(bu)會(hui)重復他(ta)們(men)的(de)(de)(de)(de)(de)軌跡，以(yi)避免磨(mo)(mo)(mo)損明顯(xian)增加(jia)了密(mi)封環(huan)的(de)(de)(de)(de)(de)表(biao)(biao)(biao)面粗糙(cao)度。此外，運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)方(fang)向(xiang)的(de)(de)(de)(de)(de)改(gai)變不(bu)能使(shi)磨(mo)(mo)(mo)粒分布(bu)比(bi)較均勻(yun)，且(qie)均勻(yun)切(qie)斷(duan)金屬密(mi)封環(huan)的(de)(de)(de)(de)(de)表(biao)(biao)(biao)面。

　　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定襄機械密封將(jiang)熱量傳(chuan)給軸承(cheng)，使軸承(cheng)溫度升高。為了控制傳(chuan)熱，所(suo)以密封的水(shui)也起(qi)到冷卻作用。

　　定襄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定襄機械密封低(di)壓(ya)側(大氣(qi))將(jiang)清水(shui)(shui)、蒸汽(qi)等(deng)冷(leng)(leng)卻流(liu)體(ti)直接引入密封端泄(xie)露處(chu)的一(yi)種冷(leng)(leng)卻方式，也稱急(ji)(ji)(ji)冷(leng)(leng)，急(ji)(ji)(ji)冷(leng)(leng)不僅冷(leng)(leng)卻*，還能將(jiang)密封端面周圍的雜質及(ji)泄(xie)露液(ye)帶走，急(ji)(ji)(ji)冷(leng)(leng)液(ye)其(qi)壓(ya)力比密封介(jie)質壓(ya)力低(di)。急(ji)(ji)(ji)冷(leng)(leng)液(ye)應盡(jin)量采用軟水(shui)(shui)，以防止水(shui)(shui)垢產生(sheng)破壞密封端面。當密封流(liu)體(ti)為易凝(ning)(ning)固、易結晶時(shi)，可用蒸汽(qi)、溶劑等(deng)防止流(liu)體(ti)凝(ning)(ning)結。
