在研磨過程中，閥門制造的密封面是一個常用的整理方法，可以使雙塔機械密封摩擦端面尺寸(cun)精(jing)度(du)提高，閥門(men)的(de)密封面，幾(ji)何粗糙(cao)度(du)和表面粗糙(cao)度(du)，但不能提高密封表面的(de)相互位(wei)置精(jing)度(du)。

　　雙塔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，隨著對雙塔機械密封研(yan)(yan)究的(de)(de)復(fu)雜面(mian)(mian)(mian)，之(zhi)間的(de)(de)表面(mian)(mian)(mian)和密(mi)(mi)封(feng)(feng)(feng)磨(mo)(mo)(mo)料磨(mo)(mo)(mo)具(ju)研(yan)(yan)究相對運動(dong)(dong)(dong)時，密(mi)(mi)封(feng)(feng)(feng)圈(quan)(quan)表面(mian)(mian)(mian)，磨(mo)(mo)(mo)料磨(mo)(mo)(mo)具(ju)研(yan)(yan)究部分和密(mi)(mi)封(feng)(feng)(feng)面(mian)(mian)(mian)之(zhi)間的(de)(de)滑動(dong)(dong)(dong)或滾動(dong)(dong)(dong)，切(qie)斷(duan)密(mi)(mi)封(feng)(feng)(feng)圈(quan)(quan)上(shang)薄(bo)(bo)薄(bo)(bo)的(de)(de)一層(ceng)金(jin)屬表面(mian)(mian)(mian)。密(mi)(mi)封(feng)(feng)(feng)凸峰部分的(de)(de)圈(quan)(quan)，表面(mian)(mian)(mian)研(yan)(yan)磨(mo)(mo)(mo)，然后逐漸達到所要(yao)求的(de)(de)幾何形狀。不僅(jin)是金(jin)屬磨(mo)(mo)(mo)料的(de)(de)研(yan)(yan)磨(mo)(mo)(mo)加(jia)(jia)工，以及化學(xue)作用。研(yan)(yan)磨(mo)(mo)(mo)油可使(shi)加(jia)(jia)工表面(mian)(mian)(mian)形成的(de)(de)氧化膜，從而加(jia)(jia)快研(yan)(yan)磨(mo)(mo)(mo)過程。地面(mian)(mian)(mian)運動(dong)(dong)(dong)相對運動(dong)(dong)(dong)的(de)(de)表面(mian)(mian)(mian)和密(mi)(mi)封(feng)(feng)(feng)圈(quan)(quan)密(mi)(mi)封(feng)(feng)(feng)圈(quan)(quan)的(de)(de)研(yan)(yan)究，對每(mei)個點的(de)(de)表面(mian)(mian)(mian)上(shang)的(de)(de)道路(lu)和相對滑動(dong)(dong)(dong)的(de)(de)研(yan)(yan)究應(ying)該是一樣(yang)的(de)(de)。和相對運動(dong)(dong)(dong)方(fang)向改變。改變密(mi)(mi)封(feng)(feng)(feng)環內的(de)(de)每(mei)個粒子的(de)(de)表面(mian)(mian)(mian)上(shang)運動(dong)(dong)(dong)的(de)(de)方(fang)向不會(hui)重復(fu)他們(men)的(de)(de)軌跡，以避免磨(mo)(mo)(mo)損明顯增加(jia)(jia)了密(mi)(mi)封(feng)(feng)(feng)環的(de)(de)表面(mian)(mian)(mian)粗糙度。此外，運動(dong)(dong)(dong)方(fang)向的(de)(de)改變不能使(shi)磨(mo)(mo)(mo)粒分布(bu)比較均勻，且均勻切(qie)斷(duan)金(jin)屬密(mi)(mi)封(feng)(feng)(feng)環的(de)(de)表面(mian)(mian)(mian)。

　　雙塔機械密封研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)是利用(yong)涂敷或者壓嵌(qian)(qian)游離磨(mo)(mo)(mo)(mo)(mo)粒(li)與(yu)(yu)(yu)(yu)(yu)研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)劑的(de)(de)(de)(de)混合物(wu)(wu)，在(zai)一定(ding)剛(gang)性的(de)(de)(de)(de)軟質研(yan)(yan)(yan)(yan)(yan)具(ju)(ju)上，通過(guo)研(yan)(yan)(yan)(yan)(yan)具(ju)(ju)與(yu)(yu)(yu)(yu)(yu)工(gong)(gong)件(jian)(jian)向磨(mo)(mo)(mo)(mo)(mo)料施加(jia)一定(ding)壓力，磨(mo)(mo)(mo)(mo)(mo)料滾動(dong)(dong)(dong)(dong)與(yu)(yu)(yu)(yu)(yu)滑(hua)(hua)(hua)動(dong)(dong)(dong)(dong)，從被(bei)研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)工(gong)(gong)件(jian)(jian)上去除極薄的(de)(de)(de)(de)余(yu)量，以(yi)(yi)提高(gao)工(gong)(gong)件(jian)(jian)的(de)(de)(de)(de)精度(du)和降低表(biao)面(mian)(mian)粗糙度(du)值(zhi)得加(jia)工(gong)(gong)方法。按研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)時(shi)有(you)無(wu)研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)液可分(fen)為干研(yan)(yan)(yan)(yan)(yan)與(yu)(yu)(yu)(yu)(yu)濕研(yan)(yan)(yan)(yan)(yan)。研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)過(guo)程中，在(zai)研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)壓力下，眾多(duo)的(de)(de)(de)(de)磨(mo)(mo)(mo)(mo)(mo)料微(wei)粒(li)進行微(wei)量切削(xue)。對工(gong)(gong)件(jian)(jian)表(biao)面(mian)(mian)進行擠壓、刻(ke)劃、滑(hua)(hua)(hua)擦(ca)(ca)；在(zai)研(yan)(yan)(yan)(yan)(yan)具(ju)(ju)運動(dong)(dong)(dong)(dong)中當研(yan)(yan)(yan)(yan)(yan)具(ju)(ju)壓嵌(qian)(qian)的(de)(de)(de)(de)磨(mo)(mo)(mo)(mo)(mo)粒(li)脫落后(hou)及(ji)(ji)液中磨(mo)(mo)(mo)(mo)(mo)粒(li)相對工(gong)(gong)件(jian)(jian)發生滾動(dong)(dong)(dong)(dong)。研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)過(guo)程中，在(zai)研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)壓力的(de)(de)(de)(de)作用(yong)下，眾多(duo)磨(mo)(mo)(mo)(mo)(mo)粒(li)進行微(wei)量切削(xue)，同(tong)時(shi)被(bei)研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)表(biao)面(mian)(mian)發生微(wei)小(xiao)起(qi)伏的(de)(de)(de)(de)塑(su)性變(bian)形，并且被(bei)加(jia)入(ru)的(de)(de)(de)(de)諸如硬脂酸(suan)、油(you)酸(suan)、脂肪酸(suan)等活(huo)性物(wu)(wu)質與(yu)(yu)(yu)(yu)(yu)被(bei)研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)表(biao)面(mian)(mian)起(qi)化學(xue)(xue)作用(yong)。隨著(zhu)研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)加(jia)工(gong)(gong)的(de)(de)(de)(de)進行，磨(mo)(mo)(mo)(mo)(mo)具(ju)(ju)與(yu)(yu)(yu)(yu)(yu)工(gong)(gong)件(jian)(jian)表(biao)面(mian)(mian)間(jian)更趨(qu)貼近，其間(jian)充滿了微(wei)屑與(yu)(yu)(yu)(yu)(yu)破(po)碎(sui)磨(mo)(mo)(mo)(mo)(mo)料的(de)(de)(de)(de)碎(sui)渣，堵塞(sai)(sai)了研(yan)(yan)(yan)(yan)(yan)具(ju)(ju)表(biao)面(mian)(mian)，對工(gong)(gong)件(jian)(jian)表(biao)面(mian)(mian)起(qi)滑(hua)(hua)(hua)擦(ca)(ca)作用(yong)。所(suo)以(yi)(yi)，研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)加(jia)工(gong)(gong)的(de)(de)(de)(de)實質是磨(mo)(mo)(mo)(mo)(mo)粒(li)的(de)(de)(de)(de)微(wei)量切削(xue)、研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)表(biao)面(mian)(mian)微(wei)小(xiao)起(qi)伏的(de)(de)(de)(de)塑(su)性流動(dong)(dong)(dong)(dong)、表(biao)面(mian)(mian)活(huo)性物(wu)(wu)質的(de)(de)(de)(de)化學(xue)(xue)作用(yong)及(ji)(ji)研(yan)(yan)(yan)(yan)(yan)具(ju)(ju)堵塞(sai)(sai)物(wu)(wu)與(yu)(yu)(yu)(yu)(yu)工(gong)(gong)件(jian)(jian)表(biao)面(mian)(mian)滑(hua)(hua)(hua)擦(ca)(ca)作用(yong)的(de)(de)(de)(de)綜合結果。

　　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雙塔機械密封將熱(re)量傳(chuan)給(gei)軸承，使軸承溫度升高。為(wei)了(le)控制(zhi)傳(chuan)熱(re)，所以密封的水也起(qi)到冷卻作(zuo)用。

　　雙塔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雙塔機械密封低(di)壓(ya)側(大氣(qi))將清水、蒸汽等冷(leng)(leng)卻流體(ti)(ti)直(zhi)接(jie)引入(ru)密封(feng)(feng)(feng)端泄露(lu)處的(de)(de)一種冷(leng)(leng)卻方式，也(ye)稱急(ji)冷(leng)(leng)，急(ji)冷(leng)(leng)不僅冷(leng)(leng)卻*，還能將密封(feng)(feng)(feng)端面周圍(wei)的(de)(de)雜質及泄露(lu)液帶走，急(ji)冷(leng)(leng)液其壓(ya)力比(bi)密封(feng)(feng)(feng)介(jie)質壓(ya)力低(di)。急(ji)冷(leng)(leng)液應盡量采用軟水，以(yi)防(fang)止水垢產(chan)生破壞(huai)密封(feng)(feng)(feng)端面。當密封(feng)(feng)(feng)流體(ti)(ti)為易凝(ning)固、易結晶時，可用蒸汽、溶劑等防(fang)止流體(ti)(ti)凝(ning)結。
