在研磨過程中，閥門制造的密封面是一個常用的整理方法，可以使河西機械密封摩擦端面(mian)尺寸(cun)精度(du)提高(gao)，閥門的密封(feng)面(mian)，幾何粗糙(cao)度(du)和表面(mian)粗糙(cao)度(du)，但(dan)不(bu)能(neng)提高(gao)密封(feng)表面(mian)的相互位(wei)置精度(du)。

　　河西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，隨著對河西機械密封研(yan)(yan)(yan)究的(de)(de)(de)(de)(de)復(fu)雜面(mian)(mian)，之(zhi)間的(de)(de)(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)和(he)密封(feng)磨(mo)料磨(mo)具研(yan)(yan)(yan)究相(xiang)對(dui)(dui)運動(dong)(dong)(dong)時，密封(feng)圈表(biao)(biao)(biao)面(mian)(mian)，磨(mo)料磨(mo)具研(yan)(yan)(yan)究部分(fen)和(he)密封(feng)面(mian)(mian)之(zhi)間的(de)(de)(de)(de)(de)滑(hua)動(dong)(dong)(dong)或滾動(dong)(dong)(dong)，切斷(duan)密封(feng)圈上(shang)薄薄的(de)(de)(de)(de)(de)一層金屬(shu)(shu)表(biao)(biao)(biao)面(mian)(mian)。密封(feng)凸(tu)峰部分(fen)的(de)(de)(de)(de)(de)圈，表(biao)(biao)(biao)面(mian)(mian)研(yan)(yan)(yan)磨(mo)，然后逐漸(jian)達到(dao)所要求的(de)(de)(de)(de)(de)幾何形(xing)狀。不僅是金屬(shu)(shu)磨(mo)料的(de)(de)(de)(de)(de)研(yan)(yan)(yan)磨(mo)加工(gong)，以及化(hua)學(xue)作用。研(yan)(yan)(yan)磨(mo)油可使(shi)加工(gong)表(biao)(biao)(biao)面(mian)(mian)形(xing)成的(de)(de)(de)(de)(de)氧化(hua)膜，從而(er)加快研(yan)(yan)(yan)磨(mo)過程。地(di)面(mian)(mian)運動(dong)(dong)(dong)相(xiang)對(dui)(dui)運動(dong)(dong)(dong)的(de)(de)(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)和(he)密封(feng)圈密封(feng)圈的(de)(de)(de)(de)(de)研(yan)(yan)(yan)究，對(dui)(dui)每個(ge)點的(de)(de)(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)上(shang)的(de)(de)(de)(de)(de)道路(lu)和(he)相(xiang)對(dui)(dui)滑(hua)動(dong)(dong)(dong)的(de)(de)(de)(de)(de)研(yan)(yan)(yan)究應該是一樣的(de)(de)(de)(de)(de)。和(he)相(xiang)對(dui)(dui)運動(dong)(dong)(dong)方(fang)向改(gai)變。改(gai)變密封(feng)環(huan)內的(de)(de)(de)(de)(de)每個(ge)粒子的(de)(de)(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)上(shang)運動(dong)(dong)(dong)的(de)(de)(de)(de)(de)方(fang)向不會重復(fu)他們(men)的(de)(de)(de)(de)(de)軌跡，以避免磨(mo)損(sun)明顯增加了密封(feng)環(huan)的(de)(de)(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)粗糙度。此(ci)外，運動(dong)(dong)(dong)方(fang)向的(de)(de)(de)(de)(de)改(gai)變不能使(shi)磨(mo)粒分(fen)布比較(jiao)均勻，且均勻切斷(duan)金屬(shu)(shu)密封(feng)環(huan)的(de)(de)(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)。

　　河西機械密封研(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)(mo)是利(li)用(yong)(yong)涂敷或者(zhe)壓(ya)嵌(qian)(qian)游(you)離磨(mo)(mo)(mo)(mo)(mo)(mo)粒與(yu)研(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)(mo)劑的(de)(de)(de)(de)(de)(de)(de)混(hun)合(he)物(wu)，在(zai)(zai)一定(ding)剛性(xing)(xing)的(de)(de)(de)(de)(de)(de)(de)軟質研(yan)(yan)(yan)具(ju)上，通過(guo)研(yan)(yan)(yan)具(ju)與(yu)工(gong)(gong)(gong)(gong)件向磨(mo)(mo)(mo)(mo)(mo)(mo)料施加一定(ding)壓(ya)力(li)，磨(mo)(mo)(mo)(mo)(mo)(mo)料滾(gun)動(dong)與(yu)滑(hua)動(dong)，從被(bei)(bei)(bei)研(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)(mo)工(gong)(gong)(gong)(gong)件上去除極薄的(de)(de)(de)(de)(de)(de)(de)余量(liang)(liang)，以提高工(gong)(gong)(gong)(gong)件的(de)(de)(de)(de)(de)(de)(de)精度(du)和降低表(biao)面(mian)(mian)粗糙度(du)值(zhi)得加工(gong)(gong)(gong)(gong)方法。按研(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)(mo)時有無研(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)(mo)液(ye)可分為(wei)干研(yan)(yan)(yan)與(yu)濕(shi)研(yan)(yan)(yan)。研(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)(mo)過(guo)程(cheng)中，在(zai)(zai)研(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)(mo)壓(ya)力(li)下(xia)，眾多的(de)(de)(de)(de)(de)(de)(de)磨(mo)(mo)(mo)(mo)(mo)(mo)料微粒進(jin)行(xing)(xing)微量(liang)(liang)切(qie)削(xue)。對工(gong)(gong)(gong)(gong)件表(biao)面(mian)(mian)進(jin)行(xing)(xing)擠壓(ya)、刻劃(hua)、滑(hua)擦(ca)；在(zai)(zai)研(yan)(yan)(yan)具(ju)運動(dong)中當研(yan)(yan)(yan)具(ju)壓(ya)嵌(qian)(qian)的(de)(de)(de)(de)(de)(de)(de)磨(mo)(mo)(mo)(mo)(mo)(mo)粒脫落后及(ji)液(ye)中磨(mo)(mo)(mo)(mo)(mo)(mo)粒相對工(gong)(gong)(gong)(gong)件發(fa)生(sheng)滾(gun)動(dong)。研(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)(mo)過(guo)程(cheng)中，在(zai)(zai)研(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)(mo)壓(ya)力(li)的(de)(de)(de)(de)(de)(de)(de)作(zuo)用(yong)(yong)下(xia)，眾多磨(mo)(mo)(mo)(mo)(mo)(mo)粒進(jin)行(xing)(xing)微量(liang)(liang)切(qie)削(xue)，同時被(bei)(bei)(bei)研(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)(mo)表(biao)面(mian)(mian)發(fa)生(sheng)微小起伏(fu)的(de)(de)(de)(de)(de)(de)(de)塑性(xing)(xing)變形，并且被(bei)(bei)(bei)加入的(de)(de)(de)(de)(de)(de)(de)諸如(ru)硬脂酸、油酸、脂肪(fang)酸等活性(xing)(xing)物(wu)質與(yu)被(bei)(bei)(bei)研(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)(mo)表(biao)面(mian)(mian)起化學作(zuo)用(yong)(yong)。隨著研(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)(mo)加工(gong)(gong)(gong)(gong)的(de)(de)(de)(de)(de)(de)(de)進(jin)行(xing)(xing)，磨(mo)(mo)(mo)(mo)(mo)(mo)具(ju)與(yu)工(gong)(gong)(gong)(gong)件表(biao)面(mian)(mian)間(jian)更趨貼(tie)近，其(qi)間(jian)充滿了(le)微屑(xie)與(yu)破碎磨(mo)(mo)(mo)(mo)(mo)(mo)料的(de)(de)(de)(de)(de)(de)(de)碎渣，堵(du)塞了(le)研(yan)(yan)(yan)具(ju)表(biao)面(mian)(mian)，對工(gong)(gong)(gong)(gong)件表(biao)面(mian)(mian)起滑(hua)擦(ca)作(zuo)用(yong)(yong)。所以，研(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)(mo)加工(gong)(gong)(gong)(gong)的(de)(de)(de)(de)(de)(de)(de)實質是磨(mo)(mo)(mo)(mo)(mo)(mo)粒的(de)(de)(de)(de)(de)(de)(de)微量(liang)(liang)切(qie)削(xue)、研(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)(mo)表(biao)面(mian)(mian)微小起伏(fu)的(de)(de)(de)(de)(de)(de)(de)塑性(xing)(xing)流動(dong)、表(biao)面(mian)(mian)活性(xing)(xing)物(wu)質的(de)(de)(de)(de)(de)(de)(de)化學作(zuo)用(yong)(yong)及(ji)研(yan)(yan)(yan)具(ju)堵(du)塞物(wu)與(yu)工(gong)(gong)(gong)(gong)件表(biao)面(mian)(mian)滑(hua)擦(ca)作(zuo)用(yong)(yong)的(de)(de)(de)(de)(de)(de)(de)綜合(he)結果(guo)。

　　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河西機械密封將(jiang)熱量傳給軸(zhou)承(cheng)(cheng)，使軸(zhou)承(cheng)(cheng)溫度升高。為了控制(zhi)傳熱，所以密封的(de)水(shui)也起到(dao)冷卻作用。

　　河西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河西機械密封低壓(ya)側(大(da)氣)將清水(shui)(shui)、蒸汽(qi)等冷(leng)卻(que)流(liu)體直接(jie)引(yin)入密(mi)封(feng)端泄(xie)露處的(de)一種冷(leng)卻(que)方式，也稱急冷(leng)，急冷(leng)不(bu)僅冷(leng)卻(que)*，還能(neng)將密(mi)封(feng)端面(mian)周圍的(de)雜(za)質及(ji)泄(xie)露液(ye)(ye)帶走(zou)，急冷(leng)液(ye)(ye)其壓(ya)力比(bi)密(mi)封(feng)介質壓(ya)力低。急冷(leng)液(ye)(ye)應盡量采(cai)用(yong)軟水(shui)(shui)，以防止(zhi)水(shui)(shui)垢產生(sheng)破壞密(mi)封(feng)端面(mian)。當密(mi)封(feng)流(liu)體為易凝固、易結晶(jing)時，可用(yong)蒸汽(qi)、溶劑等防止(zhi)流(liu)體凝結。
