在研磨過程中，閥門制造的密封面是一個常用的整理方法，可以使大英機械密封摩擦端面(mian)尺寸(cun)精度(du)提高(gao)，閥門的密(mi)封面(mian)，幾何粗(cu)糙度(du)和表面(mian)粗(cu)糙度(du)，但不能提高(gao)密(mi)封表面(mian)的相互(hu)位置精度(du)。

　　大英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，隨著對大英機械密封研(yan)(yan)究(jiu)的(de)(de)復(fu)雜面(mian)，之間的(de)(de)表(biao)(biao)(biao)面(mian)和密(mi)封(feng)(feng)(feng)磨(mo)料(liao)磨(mo)具(ju)研(yan)(yan)究(jiu)相(xiang)對(dui)運(yun)動(dong)時，密(mi)封(feng)(feng)(feng)圈(quan)表(biao)(biao)(biao)面(mian)，磨(mo)料(liao)磨(mo)具(ju)研(yan)(yan)究(jiu)部(bu)(bu)分(fen)和密(mi)封(feng)(feng)(feng)面(mian)之間的(de)(de)滑(hua)動(dong)或(huo)滾動(dong)，切斷(duan)密(mi)封(feng)(feng)(feng)圈(quan)上(shang)薄(bo)薄(bo)的(de)(de)一(yi)層(ceng)金屬(shu)表(biao)(biao)(biao)面(mian)。密(mi)封(feng)(feng)(feng)凸峰部(bu)(bu)分(fen)的(de)(de)圈(quan)，表(biao)(biao)(biao)面(mian)研(yan)(yan)磨(mo)，然后逐漸達到所要求的(de)(de)幾(ji)何形狀。不(bu)僅是金屬(shu)磨(mo)料(liao)的(de)(de)研(yan)(yan)磨(mo)加(jia)工，以及化(hua)學(xue)作用。研(yan)(yan)磨(mo)油可使加(jia)工表(biao)(biao)(biao)面(mian)形成的(de)(de)氧化(hua)膜(mo)，從而(er)加(jia)快研(yan)(yan)磨(mo)過(guo)程。地面(mian)運(yun)動(dong)相(xiang)對(dui)運(yun)動(dong)的(de)(de)表(biao)(biao)(biao)面(mian)和密(mi)封(feng)(feng)(feng)圈(quan)密(mi)封(feng)(feng)(feng)圈(quan)的(de)(de)研(yan)(yan)究(jiu)，對(dui)每個點的(de)(de)表(biao)(biao)(biao)面(mian)上(shang)的(de)(de)道(dao)路和相(xiang)對(dui)滑(hua)動(dong)的(de)(de)研(yan)(yan)究(jiu)應(ying)該(gai)是一(yi)樣的(de)(de)。和相(xiang)對(dui)運(yun)動(dong)方向(xiang)改(gai)變。改(gai)變密(mi)封(feng)(feng)(feng)環內的(de)(de)每個粒子的(de)(de)表(biao)(biao)(biao)面(mian)上(shang)運(yun)動(dong)的(de)(de)方向(xiang)不(bu)會(hui)重復(fu)他們的(de)(de)軌跡，以避免(mian)磨(mo)損(sun)明顯增加(jia)了密(mi)封(feng)(feng)(feng)環的(de)(de)表(biao)(biao)(biao)面(mian)粗(cu)糙度。此外，運(yun)動(dong)方向(xiang)的(de)(de)改(gai)變不(bu)能使磨(mo)粒分(fen)布比較均勻(yun)，且(qie)均勻(yun)切斷(duan)金屬(shu)密(mi)封(feng)(feng)(feng)環的(de)(de)表(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大英機械密封將熱(re)量傳給(gei)軸(zhou)承，使軸(zhou)承溫度(du)升(sheng)高。為了控制傳熱(re)，所以密封的水也起(qi)到冷卻作用。

　　大英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大英機械密封低(di)壓側(大氣)將清水、蒸汽(qi)等冷(leng)(leng)(leng)卻(que)流體(ti)直接(jie)引入密(mi)封端泄(xie)露處的一種冷(leng)(leng)(leng)卻(que)方(fang)式，也稱急(ji)(ji)冷(leng)(leng)(leng)，急(ji)(ji)冷(leng)(leng)(leng)不僅(jin)冷(leng)(leng)(leng)卻(que)*，還能將密(mi)封端面周圍的雜(za)質(zhi)及泄(xie)露液帶走，急(ji)(ji)冷(leng)(leng)(leng)液其壓力(li)比密(mi)封介(jie)質(zhi)壓力(li)低(di)。急(ji)(ji)冷(leng)(leng)(leng)液應盡量采用軟水，以(yi)防(fang)止(zhi)水垢(gou)產生破壞密(mi)封端面。當密(mi)封流體(ti)為易(yi)凝(ning)固、易(yi)結晶(jing)時，可用蒸汽(qi)、溶劑(ji)等防(fang)止(zhi)流體(ti)凝(ning)結。
