在研磨過程中，閥門制造的密封面是一個常用的整理方法，可以使青白江機械密封摩擦端面尺寸精度提高，閥門的密(mi)封(feng)(feng)面，幾何(he)粗糙度和(he)表面粗糙度，但不能提高密(mi)封(feng)(feng)表面的相互位置(zhi)精度。

　　青白江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，隨著對青白江機械密封研(yan)(yan)究(jiu)的(de)(de)復(fu)雜面(mian)，之間的(de)(de)表(biao)(biao)面(mian)和(he)(he)密(mi)封(feng)磨(mo)料磨(mo)具(ju)研(yan)(yan)究(jiu)相對(dui)(dui)(dui)運(yun)(yun)動(dong)時，密(mi)封(feng)圈表(biao)(biao)面(mian)，磨(mo)料磨(mo)具(ju)研(yan)(yan)究(jiu)部(bu)分(fen)和(he)(he)密(mi)封(feng)面(mian)之間的(de)(de)滑(hua)動(dong)或滾動(dong)，切斷密(mi)封(feng)圈上薄薄的(de)(de)一層金(jin)屬(shu)(shu)表(biao)(biao)面(mian)。密(mi)封(feng)凸峰部(bu)分(fen)的(de)(de)圈，表(biao)(biao)面(mian)研(yan)(yan)磨(mo)，然后逐漸達到所要求(qiu)的(de)(de)幾何形(xing)狀。不僅是金(jin)屬(shu)(shu)磨(mo)料的(de)(de)研(yan)(yan)磨(mo)加工(gong)(gong)，以及(ji)化學作用(yong)。研(yan)(yan)磨(mo)油可使加工(gong)(gong)表(biao)(biao)面(mian)形(xing)成(cheng)的(de)(de)氧(yang)化膜，從而(er)加快研(yan)(yan)磨(mo)過(guo)程。地(di)面(mian)運(yun)(yun)動(dong)相對(dui)(dui)(dui)運(yun)(yun)動(dong)的(de)(de)表(biao)(biao)面(mian)和(he)(he)密(mi)封(feng)圈密(mi)封(feng)圈的(de)(de)研(yan)(yan)究(jiu)，對(dui)(dui)(dui)每(mei)個點的(de)(de)表(biao)(biao)面(mian)上的(de)(de)道(dao)路和(he)(he)相對(dui)(dui)(dui)滑(hua)動(dong)的(de)(de)研(yan)(yan)究(jiu)應該是一樣的(de)(de)。和(he)(he)相對(dui)(dui)(dui)運(yun)(yun)動(dong)方(fang)向改變。改變密(mi)封(feng)環(huan)內的(de)(de)每(mei)個粒子的(de)(de)表(biao)(biao)面(mian)上運(yun)(yun)動(dong)的(de)(de)方(fang)向不會重復(fu)他(ta)們的(de)(de)軌跡，以避免(mian)磨(mo)損明顯增加了密(mi)封(feng)環(huan)的(de)(de)表(biao)(biao)面(mian)粗(cu)糙度。此外，運(yun)(yun)動(dong)方(fang)向的(de)(de)改變不能使磨(mo)粒分(fen)布比較均(jun)勻，且均(jun)勻切斷金(jin)屬(shu)(shu)密(mi)封(feng)環(huan)的(de)(de)表(biao)(biao)面(mian)。

　　青白江機械密封研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)是利用(yong)涂敷或(huo)者壓(ya)(ya)嵌游離磨(mo)(mo)(mo)粒(li)(li)(li)與(yu)研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)劑的(de)(de)混合物(wu)，在一定(ding)剛(gang)性(xing)的(de)(de)軟質研(yan)(yan)(yan)(yan)(yan)具(ju)上，通(tong)過(guo)研(yan)(yan)(yan)(yan)(yan)具(ju)與(yu)工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)向磨(mo)(mo)(mo)料施加一定(ding)壓(ya)(ya)力，磨(mo)(mo)(mo)料滾(gun)動(dong)(dong)與(yu)滑(hua)動(dong)(dong)，從被研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)上去除極薄的(de)(de)余量(liang)，以提高工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)的(de)(de)精(jing)度和降低表(biao)面(mian)(mian)(mian)粗糙度值(zhi)得加工(gong)(gong)(gong)(gong)方法。按(an)研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)時有無研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)液可分為(wei)干(gan)研(yan)(yan)(yan)(yan)(yan)與(yu)濕研(yan)(yan)(yan)(yan)(yan)。研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)過(guo)程中，在研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)壓(ya)(ya)力下(xia)，眾多的(de)(de)磨(mo)(mo)(mo)料微(wei)(wei)粒(li)(li)(li)進(jin)(jin)行(xing)微(wei)(wei)量(liang)切削。對工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)表(biao)面(mian)(mian)(mian)進(jin)(jin)行(xing)擠壓(ya)(ya)、刻劃、滑(hua)擦(ca)；在研(yan)(yan)(yan)(yan)(yan)具(ju)運動(dong)(dong)中當研(yan)(yan)(yan)(yan)(yan)具(ju)壓(ya)(ya)嵌的(de)(de)磨(mo)(mo)(mo)粒(li)(li)(li)脫落后及液中磨(mo)(mo)(mo)粒(li)(li)(li)相對工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)發(fa)生滾(gun)動(dong)(dong)。研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)過(guo)程中，在研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)壓(ya)(ya)力的(de)(de)作(zuo)用(yong)下(xia)，眾多磨(mo)(mo)(mo)粒(li)(li)(li)進(jin)(jin)行(xing)微(wei)(wei)量(liang)切削，同時被研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)表(biao)面(mian)(mian)(mian)發(fa)生微(wei)(wei)小(xiao)(xiao)起(qi)(qi)(qi)伏的(de)(de)塑性(xing)變形，并(bing)且被加入的(de)(de)諸如硬脂酸、油酸、脂肪酸等活性(xing)物(wu)質與(yu)被研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)表(biao)面(mian)(mian)(mian)起(qi)(qi)(qi)化學(xue)作(zuo)用(yong)。隨著研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)加工(gong)(gong)(gong)(gong)的(de)(de)進(jin)(jin)行(xing)，磨(mo)(mo)(mo)具(ju)與(yu)工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)表(biao)面(mian)(mian)(mian)間(jian)更趨貼(tie)近(jin)，其間(jian)充(chong)滿了微(wei)(wei)屑與(yu)破碎磨(mo)(mo)(mo)料的(de)(de)碎渣，堵塞了研(yan)(yan)(yan)(yan)(yan)具(ju)表(biao)面(mian)(mian)(mian)，對工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)表(biao)面(mian)(mian)(mian)起(qi)(qi)(qi)滑(hua)擦(ca)作(zuo)用(yong)。所以，研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)加工(gong)(gong)(gong)(gong)的(de)(de)實質是磨(mo)(mo)(mo)粒(li)(li)(li)的(de)(de)微(wei)(wei)量(liang)切削、研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)表(biao)面(mian)(mian)(mian)微(wei)(wei)小(xiao)(xiao)起(qi)(qi)(qi)伏的(de)(de)塑性(xing)流動(dong)(dong)、表(biao)面(mian)(mian)(mian)活性(xing)物(wu)質的(de)(de)化學(xue)作(zuo)用(yong)及研(yan)(yan)(yan)(yan)(yan)具(ju)堵塞物(wu)與(yu)工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)表(biao)面(mian)(mian)(mian)滑(hua)擦(ca)作(zuo)用(yong)的(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青白江機械密封將熱量(liang)傳給軸承，使軸承溫度升高(gao)。為了(le)控制(zhi)傳熱，所以密(mi)封的水也起到冷卻作用(yong)。

　　青白江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青白江機械密封低壓側(ce)(大(da)氣)將(jiang)清水、蒸汽等冷(leng)(leng)卻(que)流體直接引(yin)入密(mi)封端泄露處(chu)的(de)一種冷(leng)(leng)卻(que)方式，也稱急(ji)冷(leng)(leng)，急(ji)冷(leng)(leng)不(bu)僅冷(leng)(leng)卻(que)*，還能(neng)將(jiang)密(mi)封端面周圍的(de)雜質(zhi)及泄露液帶走，急(ji)冷(leng)(leng)液其壓力(li)比密(mi)封介質(zhi)壓力(li)低。急(ji)冷(leng)(leng)液應盡量采用(yong)(yong)軟水，以防(fang)(fang)止水垢(gou)產生破壞密(mi)封端面。當密(mi)封流體為易凝固、易結(jie)晶(jing)時，可用(yong)(yong)蒸汽、溶(rong)劑等防(fang)(fang)止流體凝結(jie)。
