在研磨過程中，閥門制造的密封面是一個常用的整理方法，可以使松柏鎮機械密封摩(mo)擦端面(mian)(mian)尺(chi)寸精(jing)度(du)(du)(du)提高，閥門的密封面(mian)(mian)，幾何粗糙(cao)度(du)(du)(du)和表(biao)面(mian)(mian)粗糙(cao)度(du)(du)(du)，但(dan)不能(neng)提高密封表(biao)面(mian)(mian)的相互(hu)位置精(jing)度(du)(du)(du)。

　　松柏鎮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，隨著對松柏鎮機械密封研(yan)(yan)(yan)究的(de)(de)復雜面(mian)(mian)(mian)(mian)，之(zhi)間(jian)的(de)(de)表(biao)(biao)面(mian)(mian)(mian)(mian)和密(mi)(mi)封(feng)(feng)磨(mo)(mo)(mo)料磨(mo)(mo)(mo)具(ju)研(yan)(yan)(yan)究相(xiang)對運(yun)動(dong)(dong)(dong)(dong)時(shi)，密(mi)(mi)封(feng)(feng)圈(quan)(quan)表(biao)(biao)面(mian)(mian)(mian)(mian)，磨(mo)(mo)(mo)料磨(mo)(mo)(mo)具(ju)研(yan)(yan)(yan)究部分(fen)和密(mi)(mi)封(feng)(feng)面(mian)(mian)(mian)(mian)之(zhi)間(jian)的(de)(de)滑動(dong)(dong)(dong)(dong)或滾動(dong)(dong)(dong)(dong)，切(qie)斷(duan)密(mi)(mi)封(feng)(feng)圈(quan)(quan)上薄薄的(de)(de)一(yi)層金屬(shu)表(biao)(biao)面(mian)(mian)(mian)(mian)。密(mi)(mi)封(feng)(feng)凸峰部分(fen)的(de)(de)圈(quan)(quan)，表(biao)(biao)面(mian)(mian)(mian)(mian)研(yan)(yan)(yan)磨(mo)(mo)(mo)，然后(hou)逐漸(jian)達到所要求的(de)(de)幾(ji)何(he)形狀。不僅是金屬(shu)磨(mo)(mo)(mo)料的(de)(de)研(yan)(yan)(yan)磨(mo)(mo)(mo)加(jia)工，以及化(hua)學作用。研(yan)(yan)(yan)磨(mo)(mo)(mo)油可使加(jia)工表(biao)(biao)面(mian)(mian)(mian)(mian)形成的(de)(de)氧化(hua)膜，從(cong)而加(jia)快研(yan)(yan)(yan)磨(mo)(mo)(mo)過程(cheng)。地面(mian)(mian)(mian)(mian)運(yun)動(dong)(dong)(dong)(dong)相(xiang)對運(yun)動(dong)(dong)(dong)(dong)的(de)(de)表(biao)(biao)面(mian)(mian)(mian)(mian)和密(mi)(mi)封(feng)(feng)圈(quan)(quan)密(mi)(mi)封(feng)(feng)圈(quan)(quan)的(de)(de)研(yan)(yan)(yan)究，對每個(ge)點的(de)(de)表(biao)(biao)面(mian)(mian)(mian)(mian)上的(de)(de)道路和相(xiang)對滑動(dong)(dong)(dong)(dong)的(de)(de)研(yan)(yan)(yan)究應該(gai)是一(yi)樣(yang)的(de)(de)。和相(xiang)對運(yun)動(dong)(dong)(dong)(dong)方向(xiang)(xiang)(xiang)改變。改變密(mi)(mi)封(feng)(feng)環(huan)內的(de)(de)每個(ge)粒(li)子(zi)的(de)(de)表(biao)(biao)面(mian)(mian)(mian)(mian)上運(yun)動(dong)(dong)(dong)(dong)的(de)(de)方向(xiang)(xiang)(xiang)不會重(zhong)復他們的(de)(de)軌跡，以避免磨(mo)(mo)(mo)損明(ming)顯增(zeng)加(jia)了密(mi)(mi)封(feng)(feng)環(huan)的(de)(de)表(biao)(biao)面(mian)(mian)(mian)(mian)粗糙(cao)度(du)。此外，運(yun)動(dong)(dong)(dong)(dong)方向(xiang)(xiang)(xiang)的(de)(de)改變不能使磨(mo)(mo)(mo)粒(li)分(fen)布比較(jiao)均勻，且均勻切(qie)斷(duan)金屬(shu)密(mi)(mi)封(feng)(feng)環(huan)的(de)(de)表(biao)(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松柏鎮機械密封將(jiang)熱量(liang)傳(chuan)給軸(zhou)承，使軸(zhou)承溫度升高。為(wei)了控制傳(chuan)熱，所以密封(feng)的水也起到(dao)冷卻作用。

　　松柏鎮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松柏鎮機械密封低壓側(ce)(大氣)將清水(shui)(shui)、蒸汽等冷(leng)(leng)卻(que)流體(ti)(ti)直(zhi)接引(yin)入密(mi)封(feng)端(duan)(duan)(duan)泄露(lu)處的一種(zhong)冷(leng)(leng)卻(que)方式，也稱急(ji)冷(leng)(leng)，急(ji)冷(leng)(leng)不僅冷(leng)(leng)卻(que)*，還能將密(mi)封(feng)端(duan)(duan)(duan)面周圍的雜質及泄露(lu)液(ye)(ye)帶走(zou)，急(ji)冷(leng)(leng)液(ye)(ye)其壓力比密(mi)封(feng)介質壓力低。急(ji)冷(leng)(leng)液(ye)(ye)應盡(jin)量采用軟水(shui)(shui)，以防(fang)止水(shui)(shui)垢產(chan)生破壞密(mi)封(feng)端(duan)(duan)(duan)面。當密(mi)封(feng)流體(ti)(ti)為易(yi)凝(ning)固、易(yi)結晶時，可(ke)用蒸汽、溶(rong)劑等防(fang)止流體(ti)(ti)凝(ning)結。
