在研磨過程中，閥門制造的密封面是一個常用的整理方法，可以使沙依巴克機械密封摩擦端面尺寸精(jing)度提高(gao)，閥(fa)門的密封(feng)面，幾何粗(cu)糙度和表面粗(cu)糙度，但不能提高(gao)密封(feng)表面的相互(hu)位(wei)置精(jing)度。

　　沙依巴克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，隨著對沙依巴克機械密封研(yan)(yan)究(jiu)的(de)(de)(de)(de)(de)(de)(de)復(fu)雜面(mian)(mian)(mian)(mian)，之(zhi)間的(de)(de)(de)(de)(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)和密(mi)封(feng)(feng)磨(mo)(mo)料磨(mo)(mo)具研(yan)(yan)究(jiu)相(xiang)(xiang)對(dui)運動(dong)(dong)(dong)時，密(mi)封(feng)(feng)圈(quan)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)，磨(mo)(mo)料磨(mo)(mo)具研(yan)(yan)究(jiu)部(bu)分(fen)和密(mi)封(feng)(feng)面(mian)(mian)(mian)(mian)之(zhi)間的(de)(de)(de)(de)(de)(de)(de)滑動(dong)(dong)(dong)或滾動(dong)(dong)(dong)，切(qie)(qie)斷密(mi)封(feng)(feng)圈(quan)上薄薄的(de)(de)(de)(de)(de)(de)(de)一(yi)層金屬表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)。密(mi)封(feng)(feng)凸峰部(bu)分(fen)的(de)(de)(de)(de)(de)(de)(de)圈(quan)，表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)研(yan)(yan)磨(mo)(mo)，然后逐漸達到所要求的(de)(de)(de)(de)(de)(de)(de)幾何形狀。不僅(jin)是金屬磨(mo)(mo)料的(de)(de)(de)(de)(de)(de)(de)研(yan)(yan)磨(mo)(mo)加(jia)工，以及化學作用。研(yan)(yan)磨(mo)(mo)油可(ke)使加(jia)工表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)形成的(de)(de)(de)(de)(de)(de)(de)氧化膜，從而(er)加(jia)快研(yan)(yan)磨(mo)(mo)過(guo)程。地面(mian)(mian)(mian)(mian)運動(dong)(dong)(dong)相(xiang)(xiang)對(dui)運動(dong)(dong)(dong)的(de)(de)(de)(de)(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)和密(mi)封(feng)(feng)圈(quan)密(mi)封(feng)(feng)圈(quan)的(de)(de)(de)(de)(de)(de)(de)研(yan)(yan)究(jiu)，對(dui)每個點(dian)的(de)(de)(de)(de)(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)上的(de)(de)(de)(de)(de)(de)(de)道路(lu)和相(xiang)(xiang)對(dui)滑動(dong)(dong)(dong)的(de)(de)(de)(de)(de)(de)(de)研(yan)(yan)究(jiu)應該是一(yi)樣的(de)(de)(de)(de)(de)(de)(de)。和相(xiang)(xiang)對(dui)運動(dong)(dong)(dong)方(fang)(fang)向(xiang)改變。改變密(mi)封(feng)(feng)環內的(de)(de)(de)(de)(de)(de)(de)每個粒(li)子的(de)(de)(de)(de)(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)上運動(dong)(dong)(dong)的(de)(de)(de)(de)(de)(de)(de)方(fang)(fang)向(xiang)不會重復(fu)他(ta)們的(de)(de)(de)(de)(de)(de)(de)軌跡，以避免磨(mo)(mo)損明(ming)顯增(zeng)加(jia)了密(mi)封(feng)(feng)環的(de)(de)(de)(de)(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)粗糙(cao)度。此外，運動(dong)(dong)(dong)方(fang)(fang)向(xiang)的(de)(de)(de)(de)(de)(de)(de)改變不能使磨(mo)(mo)粒(li)分(fen)布比較均(jun)勻，且均(jun)勻切(qie)(qie)斷金屬密(mi)封(feng)(feng)環的(de)(de)(de)(de)(de)(de)(de)表(biao)(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沙依巴克機械密封將熱(re)量傳(chuan)(chuan)給軸承，使軸承溫度升高。為了控制傳(chuan)(chuan)熱(re)，所(suo)以密封的水也起(qi)到(dao)冷卻作用。

　　沙依巴克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沙依巴克機械密封低壓(ya)側(大氣(qi))將(jiang)清水(shui)、蒸(zheng)汽等冷(leng)卻(que)流(liu)體直接引入密封(feng)端(duan)泄露(lu)處的一(yi)種冷(leng)卻(que)方式(shi)，也稱急冷(leng)，急冷(leng)不僅(jin)冷(leng)卻(que)*，還能將(jiang)密封(feng)端(duan)面(mian)周圍的雜質及(ji)泄露(lu)液帶(dai)走，急冷(leng)液其壓(ya)力(li)比密封(feng)介質壓(ya)力(li)低。急冷(leng)液應盡量采用軟(ruan)水(shui)，以防止水(shui)垢產生破壞密封(feng)端(duan)面(mian)。當密封(feng)流(liu)體為(wei)易凝固(gu)、易結(jie)晶時，可(ke)用蒸(zheng)汽、溶劑等防止流(liu)體凝結(jie)。
