在研磨過程中，閥門制造的密封面是一個常用的整理方法，可以使喀什機械密封摩擦端面(mian)(mian)尺寸精度(du)提高，閥門的密封面(mian)(mian)，幾(ji)何(he)粗糙度(du)和表(biao)面(mian)(mian)粗糙度(du)，但不(bu)能提高密封表(biao)面(mian)(mian)的相(xiang)互位(wei)置精度(du)。

　　喀什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，隨著對喀什機械密封研(yan)究(jiu)的(de)(de)(de)(de)復雜面(mian)(mian)，之間的(de)(de)(de)(de)表面(mian)(mian)和(he)(he)(he)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)磨(mo)(mo)料磨(mo)(mo)具研(yan)究(jiu)相(xiang)對(dui)運(yun)(yun)動(dong)(dong)(dong)時，密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)圈(quan)表面(mian)(mian)，磨(mo)(mo)料磨(mo)(mo)具研(yan)究(jiu)部分和(he)(he)(he)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)面(mian)(mian)之間的(de)(de)(de)(de)滑(hua)動(dong)(dong)(dong)或滾動(dong)(dong)(dong)，切(qie)斷密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)圈(quan)上(shang)薄(bo)薄(bo)的(de)(de)(de)(de)一(yi)層金屬表面(mian)(mian)。密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)凸峰部分的(de)(de)(de)(de)圈(quan)，表面(mian)(mian)研(yan)磨(mo)(mo)，然(ran)后逐漸(jian)達(da)到所要求的(de)(de)(de)(de)幾何形狀(zhuang)。不僅(jin)是金屬磨(mo)(mo)料的(de)(de)(de)(de)研(yan)磨(mo)(mo)加(jia)工，以及化學作(zuo)用。研(yan)磨(mo)(mo)油可使加(jia)工表面(mian)(mian)形成(cheng)的(de)(de)(de)(de)氧化膜，從而(er)加(jia)快(kuai)研(yan)磨(mo)(mo)過程。地面(mian)(mian)運(yun)(yun)動(dong)(dong)(dong)相(xiang)對(dui)運(yun)(yun)動(dong)(dong)(dong)的(de)(de)(de)(de)表面(mian)(mian)和(he)(he)(he)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)圈(quan)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)圈(quan)的(de)(de)(de)(de)研(yan)究(jiu)，對(dui)每個(ge)點的(de)(de)(de)(de)表面(mian)(mian)上(shang)的(de)(de)(de)(de)道路和(he)(he)(he)相(xiang)對(dui)滑(hua)動(dong)(dong)(dong)的(de)(de)(de)(de)研(yan)究(jiu)應(ying)該是一(yi)樣(yang)的(de)(de)(de)(de)。和(he)(he)(he)相(xiang)對(dui)運(yun)(yun)動(dong)(dong)(dong)方向改變。改變密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)環(huan)內的(de)(de)(de)(de)每個(ge)粒子的(de)(de)(de)(de)表面(mian)(mian)上(shang)運(yun)(yun)動(dong)(dong)(dong)的(de)(de)(de)(de)方向不會重(zhong)復他們的(de)(de)(de)(de)軌(gui)跡，以避(bi)免磨(mo)(mo)損(sun)明顯增加(jia)了密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)環(huan)的(de)(de)(de)(de)表面(mian)(mian)粗糙度。此外，運(yun)(yun)動(dong)(dong)(dong)方向的(de)(de)(de)(de)改變不能(neng)使磨(mo)(mo)粒分布(bu)比較均(jun)勻(yun)，且均(jun)勻(yun)切(qie)斷金屬密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)環(huan)的(de)(de)(de)(de)表面(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喀什機械密封將熱量傳(chuan)給軸承，使(shi)軸承溫度升高。為了控制傳(chuan)熱，所以密封的水也起到冷卻作用。

　　喀什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喀什機械密封低(di)壓(ya)側(大氣)將(jiang)清水(shui)、蒸汽(qi)等冷(leng)卻流(liu)體(ti)直(zhi)接引入密(mi)封(feng)(feng)(feng)端泄露(lu)處的一種(zhong)冷(leng)卻方(fang)式，也稱急冷(leng)，急冷(leng)不僅冷(leng)卻*，還能將(jiang)密(mi)封(feng)(feng)(feng)端面周圍(wei)的雜質及泄露(lu)液(ye)帶走，急冷(leng)液(ye)其壓(ya)力(li)比密(mi)封(feng)(feng)(feng)介質壓(ya)力(li)低(di)。急冷(leng)液(ye)應(ying)盡量采用軟水(shui)，以防(fang)(fang)止(zhi)水(shui)垢產生破壞密(mi)封(feng)(feng)(feng)端面。當密(mi)封(feng)(feng)(feng)流(liu)體(ti)為易(yi)凝(ning)固、易(yi)結晶時，可用蒸汽(qi)、溶劑(ji)等防(fang)(fang)止(zhi)流(liu)體(ti)凝(ning)結。
