在研磨過程中，閥門制造的密封面是一個常用的整理方法，可以使隴南機械密封摩擦端面(mian)尺(chi)寸精度(du)(du)提高，閥門(men)的(de)密封(feng)面(mian)，幾何(he)粗糙度(du)(du)和表面(mian)粗糙度(du)(du)，但(dan)不能提高密封(feng)表面(mian)的(de)相互(hu)位置精度(du)(du)。

　　隴南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，隨著對隴南機械密封研(yan)(yan)(yan)究的(de)(de)(de)(de)復雜面(mian)(mian)(mian)，之間(jian)(jian)的(de)(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)(mian)和(he)密(mi)封(feng)(feng)(feng)(feng)磨(mo)(mo)(mo)料磨(mo)(mo)(mo)具研(yan)(yan)(yan)究相(xiang)對運動(dong)時，密(mi)封(feng)(feng)(feng)(feng)圈(quan)(quan)表(biao)(biao)(biao)面(mian)(mian)(mian)，磨(mo)(mo)(mo)料磨(mo)(mo)(mo)具研(yan)(yan)(yan)究部(bu)分和(he)密(mi)封(feng)(feng)(feng)(feng)面(mian)(mian)(mian)之間(jian)(jian)的(de)(de)(de)(de)滑動(dong)或滾(gun)動(dong)，切斷密(mi)封(feng)(feng)(feng)(feng)圈(quan)(quan)上薄薄的(de)(de)(de)(de)一(yi)層金屬(shu)表(biao)(biao)(biao)面(mian)(mian)(mian)。密(mi)封(feng)(feng)(feng)(feng)凸峰部(bu)分的(de)(de)(de)(de)圈(quan)(quan)，表(biao)(biao)(biao)面(mian)(mian)(mian)研(yan)(yan)(yan)磨(mo)(mo)(mo)，然后逐漸達到所(suo)要(yao)求的(de)(de)(de)(de)幾(ji)何形(xing)狀。不(bu)僅(jin)是金屬(shu)磨(mo)(mo)(mo)料的(de)(de)(de)(de)研(yan)(yan)(yan)磨(mo)(mo)(mo)加工(gong)，以(yi)及化(hua)學作(zuo)用。研(yan)(yan)(yan)磨(mo)(mo)(mo)油可使(shi)加工(gong)表(biao)(biao)(biao)面(mian)(mian)(mian)形(xing)成(cheng)的(de)(de)(de)(de)氧化(hua)膜，從而加快研(yan)(yan)(yan)磨(mo)(mo)(mo)過程。地面(mian)(mian)(mian)運動(dong)相(xiang)對運動(dong)的(de)(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)(mian)和(he)密(mi)封(feng)(feng)(feng)(feng)圈(quan)(quan)密(mi)封(feng)(feng)(feng)(feng)圈(quan)(quan)的(de)(de)(de)(de)研(yan)(yan)(yan)究，對每個(ge)點的(de)(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)(mian)上的(de)(de)(de)(de)道(dao)路和(he)相(xiang)對滑動(dong)的(de)(de)(de)(de)研(yan)(yan)(yan)究應(ying)該是一(yi)樣(yang)的(de)(de)(de)(de)。和(he)相(xiang)對運動(dong)方向改變。改變密(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(biao)(biao)(biao)面(mian)(mian)(mian)上運動(dong)的(de)(de)(de)(de)方向不(bu)會(hui)重復他們的(de)(de)(de)(de)軌跡，以(yi)避免磨(mo)(mo)(mo)損(sun)明顯增(zeng)加了(le)密(mi)封(feng)(feng)(feng)(feng)環(huan)的(de)(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)(mian)粗糙度(du)。此外，運動(dong)方向的(de)(de)(de)(de)改變不(bu)能使(shi)磨(mo)(mo)(mo)粒分布比較均(jun)勻，且均(jun)勻切斷金屬(shu)密(mi)封(feng)(feng)(feng)(feng)環(huan)的(de)(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)(mian)。

　　隴南機械密封研(yan)(yan)(yan)(yan)磨(mo)(mo)是利用涂(tu)敷或者壓(ya)嵌游離磨(mo)(mo)粒(li)(li)與(yu)研(yan)(yan)(yan)(yan)磨(mo)(mo)劑的(de)(de)(de)(de)混合物，在(zai)(zai)一定(ding)剛性(xing)的(de)(de)(de)(de)軟質研(yan)(yan)(yan)(yan)具(ju)(ju)(ju)上(shang)，通過研(yan)(yan)(yan)(yan)具(ju)(ju)(ju)與(yu)工(gong)(gong)(gong)件(jian)向(xiang)磨(mo)(mo)料施加一定(ding)壓(ya)力，磨(mo)(mo)料滾(gun)動(dong)(dong)與(yu)滑動(dong)(dong)，從(cong)被(bei)研(yan)(yan)(yan)(yan)磨(mo)(mo)工(gong)(gong)(gong)件(jian)上(shang)去除極薄的(de)(de)(de)(de)余量，以提高工(gong)(gong)(gong)件(jian)的(de)(de)(de)(de)精度和(he)降(jiang)低(di)表(biao)面(mian)粗糙度值得加工(gong)(gong)(gong)方法。按(an)研(yan)(yan)(yan)(yan)磨(mo)(mo)時(shi)有無研(yan)(yan)(yan)(yan)磨(mo)(mo)液(ye)可分為干(gan)研(yan)(yan)(yan)(yan)與(yu)濕(shi)研(yan)(yan)(yan)(yan)。研(yan)(yan)(yan)(yan)磨(mo)(mo)過程(cheng)中，在(zai)(zai)研(yan)(yan)(yan)(yan)磨(mo)(mo)壓(ya)力下，眾多的(de)(de)(de)(de)磨(mo)(mo)料微(wei)(wei)粒(li)(li)進(jin)行微(wei)(wei)量切削(xue)。對(dui)工(gong)(gong)(gong)件(jian)表(biao)面(mian)進(jin)行擠(ji)壓(ya)、刻(ke)劃、滑擦(ca)(ca)；在(zai)(zai)研(yan)(yan)(yan)(yan)具(ju)(ju)(ju)運動(dong)(dong)中當研(yan)(yan)(yan)(yan)具(ju)(ju)(ju)壓(ya)嵌的(de)(de)(de)(de)磨(mo)(mo)粒(li)(li)脫落(luo)后及(ji)液(ye)中磨(mo)(mo)粒(li)(li)相對(dui)工(gong)(gong)(gong)件(jian)發(fa)生(sheng)滾(gun)動(dong)(dong)。研(yan)(yan)(yan)(yan)磨(mo)(mo)過程(cheng)中，在(zai)(zai)研(yan)(yan)(yan)(yan)磨(mo)(mo)壓(ya)力的(de)(de)(de)(de)作(zuo)用下，眾多磨(mo)(mo)粒(li)(li)進(jin)行微(wei)(wei)量切削(xue)，同時(shi)被(bei)研(yan)(yan)(yan)(yan)磨(mo)(mo)表(biao)面(mian)發(fa)生(sheng)微(wei)(wei)小起(qi)伏的(de)(de)(de)(de)塑性(xing)變形，并且被(bei)加入(ru)的(de)(de)(de)(de)諸(zhu)如硬(ying)脂酸(suan)(suan)、油酸(suan)(suan)、脂肪(fang)酸(suan)(suan)等(deng)活(huo)性(xing)物質與(yu)被(bei)研(yan)(yan)(yan)(yan)磨(mo)(mo)表(biao)面(mian)起(qi)化(hua)學作(zuo)用。隨著研(yan)(yan)(yan)(yan)磨(mo)(mo)加工(gong)(gong)(gong)的(de)(de)(de)(de)進(jin)行，磨(mo)(mo)具(ju)(ju)(ju)與(yu)工(gong)(gong)(gong)件(jian)表(biao)面(mian)間更(geng)趨貼(tie)近，其(qi)間充(chong)滿了(le)微(wei)(wei)屑與(yu)破碎(sui)磨(mo)(mo)料的(de)(de)(de)(de)碎(sui)渣，堵塞(sai)了(le)研(yan)(yan)(yan)(yan)具(ju)(ju)(ju)表(biao)面(mian)，對(dui)工(gong)(gong)(gong)件(jian)表(biao)面(mian)起(qi)滑擦(ca)(ca)作(zuo)用。所以，研(yan)(yan)(yan)(yan)磨(mo)(mo)加工(gong)(gong)(gong)的(de)(de)(de)(de)實質是磨(mo)(mo)粒(li)(li)的(de)(de)(de)(de)微(wei)(wei)量切削(xue)、研(yan)(yan)(yan)(yan)磨(mo)(mo)表(biao)面(mian)微(wei)(wei)小起(qi)伏的(de)(de)(de)(de)塑性(xing)流動(dong)(dong)、表(biao)面(mian)活(huo)性(xing)物質的(de)(de)(de)(de)化(hua)學作(zuo)用及(ji)研(yan)(yan)(yan)(yan)具(ju)(ju)(ju)堵塞(sai)物與(yu)工(gong)(gong)(gong)件(jian)表(biao)面(mian)滑擦(ca)(ca)作(zuo)用的(de)(de)(de)(de)綜合結果(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隴南機械密封將熱(re)量傳給(gei)軸(zhou)(zhou)承，使軸(zhou)(zhou)承溫度(du)升高。為(wei)了控制傳熱(re)，所以(yi)密封的水也起到冷卻(que)作用(yong)。

　　隴南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隴南機械密封低(di)壓(ya)(ya)側(大氣)將清(qing)水(shui)、蒸汽等(deng)冷(leng)(leng)卻流體(ti)直接引(yin)入(ru)密(mi)(mi)(mi)封端(duan)(duan)泄露處的(de)一種冷(leng)(leng)卻方式，也稱(cheng)急冷(leng)(leng)，急冷(leng)(leng)不僅冷(leng)(leng)卻*，還能將密(mi)(mi)(mi)封端(duan)(duan)面周圍的(de)雜質(zhi)及(ji)泄露液帶走，急冷(leng)(leng)液其(qi)壓(ya)(ya)力比(bi)密(mi)(mi)(mi)封介(jie)質(zhi)壓(ya)(ya)力低(di)。急冷(leng)(leng)液應盡量采用軟(ruan)水(shui)，以防止(zhi)水(shui)垢產生(sheng)破壞密(mi)(mi)(mi)封端(duan)(duan)面。當密(mi)(mi)(mi)封流體(ti)為易凝固、易結晶時，可(ke)用蒸汽、溶劑(ji)等(deng)防止(zhi)流體(ti)凝結。
