在研磨過程中，閥門制造的密封面是一個常用的整理方法，可以使迪慶機械密封摩(mo)擦端面(mian)尺寸精(jing)度(du)提(ti)高，閥門的密封面(mian)，幾(ji)何粗糙(cao)度(du)和表面(mian)粗糙(cao)度(du)，但不能提(ti)高密封表面(mian)的相(xiang)互位置精(jing)度(du)。

　　迪慶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，隨著對迪慶機械密封研(yan)(yan)(yan)(yan)究的(de)(de)(de)(de)(de)復雜面(mian)，之間的(de)(de)(de)(de)(de)表(biao)(biao)(biao)(biao)面(mian)和(he)(he)密(mi)封(feng)(feng)磨(mo)料磨(mo)具(ju)研(yan)(yan)(yan)(yan)究相(xiang)(xiang)對運(yun)動(dong)時(shi)，密(mi)封(feng)(feng)圈表(biao)(biao)(biao)(biao)面(mian)，磨(mo)料磨(mo)具(ju)研(yan)(yan)(yan)(yan)究部分和(he)(he)密(mi)封(feng)(feng)面(mian)之間的(de)(de)(de)(de)(de)滑動(dong)或滾動(dong)，切斷密(mi)封(feng)(feng)圈上薄(bo)薄(bo)的(de)(de)(de)(de)(de)一(yi)層(ceng)金(jin)(jin)屬表(biao)(biao)(biao)(biao)面(mian)。密(mi)封(feng)(feng)凸峰(feng)部分的(de)(de)(de)(de)(de)圈，表(biao)(biao)(biao)(biao)面(mian)研(yan)(yan)(yan)(yan)磨(mo)，然后(hou)逐漸達到所(suo)要求的(de)(de)(de)(de)(de)幾何(he)形(xing)狀。不僅是(shi)金(jin)(jin)屬磨(mo)料的(de)(de)(de)(de)(de)研(yan)(yan)(yan)(yan)磨(mo)加工(gong)，以及(ji)化學作用。研(yan)(yan)(yan)(yan)磨(mo)油可使(shi)加工(gong)表(biao)(biao)(biao)(biao)面(mian)形(xing)成(cheng)的(de)(de)(de)(de)(de)氧化膜，從而加快研(yan)(yan)(yan)(yan)磨(mo)過程。地(di)面(mian)運(yun)動(dong)相(xiang)(xiang)對運(yun)動(dong)的(de)(de)(de)(de)(de)表(biao)(biao)(biao)(biao)面(mian)和(he)(he)密(mi)封(feng)(feng)圈密(mi)封(feng)(feng)圈的(de)(de)(de)(de)(de)研(yan)(yan)(yan)(yan)究，對每個點的(de)(de)(de)(de)(de)表(biao)(biao)(biao)(biao)面(mian)上的(de)(de)(de)(de)(de)道路和(he)(he)相(xiang)(xiang)對滑動(dong)的(de)(de)(de)(de)(de)研(yan)(yan)(yan)(yan)究應該(gai)是(shi)一(yi)樣的(de)(de)(de)(de)(de)。和(he)(he)相(xiang)(xiang)對運(yun)動(dong)方(fang)向改變。改變密(mi)封(feng)(feng)環內的(de)(de)(de)(de)(de)每個粒(li)子(zi)的(de)(de)(de)(de)(de)表(biao)(biao)(biao)(biao)面(mian)上運(yun)動(dong)的(de)(de)(de)(de)(de)方(fang)向不會重復他們的(de)(de)(de)(de)(de)軌(gui)跡，以避免磨(mo)損(sun)明顯增加了(le)密(mi)封(feng)(feng)環的(de)(de)(de)(de)(de)表(biao)(biao)(biao)(biao)面(mian)粗糙度。此外，運(yun)動(dong)方(fang)向的(de)(de)(de)(de)(de)改變不能(neng)使(shi)磨(mo)粒(li)分布比較均(jun)勻，且(qie)均(jun)勻切斷金(jin)(jin)屬密(mi)封(feng)(feng)環的(de)(de)(de)(de)(de)表(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迪慶機械密封將熱量傳(chuan)給軸(zhou)承(cheng)，使軸(zhou)承(cheng)溫度升(sheng)高。為了控制傳(chuan)熱，所以(yi)密封的水也起到(dao)冷卻作用。

　　迪慶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迪慶機械密封低壓側(大(da)氣)將清水(shui)(shui)、蒸汽等(deng)冷(leng)(leng)卻流體直接引入密封端(duan)泄露處(chu)的一(yi)種冷(leng)(leng)卻方式，也(ye)稱急冷(leng)(leng)，急冷(leng)(leng)不僅冷(leng)(leng)卻*，還能將密封端(duan)面(mian)(mian)周(zhou)圍的雜質及泄露液帶走，急冷(leng)(leng)液其壓力比密封介質壓力低。急冷(leng)(leng)液應(ying)盡量采用軟水(shui)(shui)，以防止(zhi)水(shui)(shui)垢(gou)產(chan)生破壞密封端(duan)面(mian)(mian)。當密封流體為易(yi)凝(ning)固(gu)、易(yi)結晶時，可用蒸汽、溶劑等(deng)防止(zhi)流體凝(ning)結。
