在研磨過程中，閥門制造的密封面是一個常用的整理方法，可以使吉首機械密封摩擦端面(mian)尺寸精度提高，閥門(men)的密封(feng)面(mian)，幾何(he)粗糙度和表面(mian)粗糙度，但不能提高密封(feng)表面(mian)的相互位置精度。

　　吉首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，隨著對吉首機械密封研(yan)(yan)(yan)(yan)究的(de)(de)(de)(de)(de)(de)(de)(de)復雜面(mian)(mian)(mian)(mian)，之(zhi)間(jian)的(de)(de)(de)(de)(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)(mian)和(he)密(mi)(mi)(mi)封(feng)磨(mo)(mo)料(liao)磨(mo)(mo)具研(yan)(yan)(yan)(yan)究相(xiang)(xiang)對運(yun)動時，密(mi)(mi)(mi)封(feng)圈表(biao)面(mian)(mian)(mian)(mian)，磨(mo)(mo)料(liao)磨(mo)(mo)具研(yan)(yan)(yan)(yan)究部分和(he)密(mi)(mi)(mi)封(feng)面(mian)(mian)(mian)(mian)之(zhi)間(jian)的(de)(de)(de)(de)(de)(de)(de)(de)滑(hua)動或(huo)滾動，切斷密(mi)(mi)(mi)封(feng)圈上(shang)薄薄的(de)(de)(de)(de)(de)(de)(de)(de)一(yi)(yi)層金(jin)(jin)屬表(biao)面(mian)(mian)(mian)(mian)。密(mi)(mi)(mi)封(feng)凸峰部分的(de)(de)(de)(de)(de)(de)(de)(de)圈，表(biao)面(mian)(mian)(mian)(mian)研(yan)(yan)(yan)(yan)磨(mo)(mo)，然(ran)后逐漸達到所要求的(de)(de)(de)(de)(de)(de)(de)(de)幾何形狀(zhuang)。不(bu)僅(jin)是金(jin)(jin)屬磨(mo)(mo)料(liao)的(de)(de)(de)(de)(de)(de)(de)(de)研(yan)(yan)(yan)(yan)磨(mo)(mo)加工(gong)(gong)，以及(ji)化學(xue)作用。研(yan)(yan)(yan)(yan)磨(mo)(mo)油可使加工(gong)(gong)表(biao)面(mian)(mian)(mian)(mian)形成的(de)(de)(de)(de)(de)(de)(de)(de)氧化膜，從(cong)而加快(kuai)研(yan)(yan)(yan)(yan)磨(mo)(mo)過程(cheng)。地面(mian)(mian)(mian)(mian)運(yun)動相(xiang)(xiang)對運(yun)動的(de)(de)(de)(de)(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)(mian)和(he)密(mi)(mi)(mi)封(feng)圈密(mi)(mi)(mi)封(feng)圈的(de)(de)(de)(de)(de)(de)(de)(de)研(yan)(yan)(yan)(yan)究，對每個點的(de)(de)(de)(de)(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)(mian)上(shang)的(de)(de)(de)(de)(de)(de)(de)(de)道路和(he)相(xiang)(xiang)對滑(hua)動的(de)(de)(de)(de)(de)(de)(de)(de)研(yan)(yan)(yan)(yan)究應(ying)該是一(yi)(yi)樣的(de)(de)(de)(de)(de)(de)(de)(de)。和(he)相(xiang)(xiang)對運(yun)動方(fang)向改(gai)變(bian)。改(gai)變(bian)密(mi)(mi)(mi)封(feng)環內的(de)(de)(de)(de)(de)(de)(de)(de)每個粒(li)子的(de)(de)(de)(de)(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)(mian)上(shang)運(yun)動的(de)(de)(de)(de)(de)(de)(de)(de)方(fang)向不(bu)會重復他(ta)們的(de)(de)(de)(de)(de)(de)(de)(de)軌跡，以避免磨(mo)(mo)損明顯增(zeng)加了密(mi)(mi)(mi)封(feng)環的(de)(de)(de)(de)(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)(mian)粗(cu)糙(cao)度。此外，運(yun)動方(fang)向的(de)(de)(de)(de)(de)(de)(de)(de)改(gai)變(bian)不(bu)能使磨(mo)(mo)粒(li)分布比較(jiao)均(jun)勻(yun)，且(qie)均(jun)勻(yun)切斷金(jin)(jin)屬密(mi)(mi)(mi)封(feng)環的(de)(de)(de)(de)(de)(de)(de)(de)表(biao)面(mian)(mian)(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吉首機械密封將熱(re)(re)量傳給軸承(cheng)，使軸承(cheng)溫度(du)升(sheng)高。為了控制傳熱(re)(re)，所以密(mi)封的水也起到(dao)冷卻作用。

　　吉首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吉首機械密封低壓側(大(da)氣)將清水(shui)、蒸(zheng)汽等(deng)冷(leng)卻流體(ti)(ti)直接引入(ru)密封(feng)端泄(xie)露處的(de)一種(zhong)冷(leng)卻方式，也(ye)稱急(ji)冷(leng)，急(ji)冷(leng)不僅(jin)冷(leng)卻*，還能將密封(feng)端面周圍的(de)雜質(zhi)及泄(xie)露液帶走，急(ji)冷(leng)液其壓力比密封(feng)介(jie)質(zhi)壓力低。急(ji)冷(leng)液應盡(jin)量(liang)采用(yong)軟水(shui)，以(yi)防止水(shui)垢(gou)產(chan)生破壞密封(feng)端面。當(dang)密封(feng)流體(ti)(ti)為(wei)易(yi)凝固、易(yi)結晶時，可用(yong)蒸(zheng)汽、溶劑等(deng)防止流體(ti)(ti)凝結。
