在研磨過程中，閥門制造的密封面是一個常用的整理方法，可以使連山機械密封摩擦端面(mian)尺寸精(jing)度(du)(du)提高，閥(fa)門的(de)密封面(mian)，幾何粗(cu)糙度(du)(du)和表(biao)面(mian)粗(cu)糙度(du)(du)，但不能(neng)提高密封表(biao)面(mian)的(de)相(xiang)互位(wei)置精(jing)度(du)(du)。

　　連山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，隨著對連山機械密封研(yan)(yan)究(jiu)的(de)(de)(de)(de)(de)復(fu)雜面(mian)(mian)(mian)，之間的(de)(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)和密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)磨(mo)料磨(mo)具研(yan)(yan)究(jiu)相對(dui)運動(dong)時(shi)，密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)圈表(biao)面(mian)(mian)(mian)，磨(mo)料磨(mo)具研(yan)(yan)究(jiu)部分(fen)和密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)面(mian)(mian)(mian)之間的(de)(de)(de)(de)(de)滑動(dong)或滾動(dong)，切(qie)斷(duan)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)圈上薄(bo)(bo)薄(bo)(bo)的(de)(de)(de)(de)(de)一(yi)層金(jin)屬表(biao)面(mian)(mian)(mian)。密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)凸峰(feng)部分(fen)的(de)(de)(de)(de)(de)圈，表(biao)面(mian)(mian)(mian)研(yan)(yan)磨(mo)，然后(hou)逐漸達到所(suo)要求(qiu)的(de)(de)(de)(de)(de)幾何形狀。不僅是(shi)(shi)金(jin)屬磨(mo)料的(de)(de)(de)(de)(de)研(yan)(yan)磨(mo)加工，以及化學作(zuo)用(yong)。研(yan)(yan)磨(mo)油可(ke)使加工表(biao)面(mian)(mian)(mian)形成(cheng)的(de)(de)(de)(de)(de)氧(yang)化膜，從而加快(kuai)研(yan)(yan)磨(mo)過程。地面(mian)(mian)(mian)運動(dong)相對(dui)運動(dong)的(de)(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)和密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)圈密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)圈的(de)(de)(de)(de)(de)研(yan)(yan)究(jiu)，對(dui)每個點(dian)的(de)(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)上的(de)(de)(de)(de)(de)道路(lu)和相對(dui)滑動(dong)的(de)(de)(de)(de)(de)研(yan)(yan)究(jiu)應(ying)該是(shi)(shi)一(yi)樣的(de)(de)(de)(de)(de)。和相對(dui)運動(dong)方(fang)向改(gai)變。改(gai)變密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)環(huan)內的(de)(de)(de)(de)(de)每個粒子的(de)(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)上運動(dong)的(de)(de)(de)(de)(de)方(fang)向不會重復(fu)他們的(de)(de)(de)(de)(de)軌跡，以避免磨(mo)損(sun)明顯增加了密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)環(huan)的(de)(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)粗糙度。此(ci)外，運動(dong)方(fang)向的(de)(de)(de)(de)(de)改(gai)變不能使磨(mo)粒分(fen)布比較(jiao)均(jun)勻，且均(jun)勻切(qie)斷(duan)金(jin)屬密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)環(huan)的(de)(de)(de)(de)(de)表(biao)面(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連山機械密封將(jiang)熱量(liang)傳(chuan)給(gei)軸承，使軸承溫度升高(gao)。為了控(kong)制傳(chuan)熱，所以密封(feng)的水也起到冷卻作用。

　　連山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連山機械密封低(di)壓(ya)側(大氣)將清水(shui)(shui)、蒸(zheng)汽等冷(leng)卻流體直接引入(ru)密(mi)(mi)封(feng)端泄露處(chu)的一種冷(leng)卻方式，也稱急(ji)冷(leng)，急(ji)冷(leng)不僅冷(leng)卻*，還(huan)能將密(mi)(mi)封(feng)端面周(zhou)圍的雜質及泄露液帶走，急(ji)冷(leng)液其壓(ya)力(li)比密(mi)(mi)封(feng)介質壓(ya)力(li)低(di)。急(ji)冷(leng)液應盡量采用軟水(shui)(shui)，以(yi)防止水(shui)(shui)垢產(chan)生(sheng)破壞密(mi)(mi)封(feng)端面。當(dang)密(mi)(mi)封(feng)流體為易凝固、易結晶(jing)時，可用蒸(zheng)汽、溶劑(ji)等防止流體凝結。
