隴縣研磨和冷卻對密封面都非常重要

  在研磨過程中,閥門制造的密封面是一個常用的整理方法,可以使隴縣機械密封摩擦端面尺寸精(jing)度提高,閥門的(de)密(mi)封面,幾何(he)粗糙(cao)度和表面粗糙(cao)度,但不能提高密(mi)封表面的(de)相互位置精(jing)度。


  隴縣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,隨著對隴縣機械密封研(yan)究的(de)(de)(de)復雜面(mian)(mian)(mian)(mian)(mian),之間(jian)的(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)(mian)和密(mi)封(feng)磨(mo)(mo)(mo)料(liao)磨(mo)(mo)(mo)具(ju)研(yan)究相(xiang)對(dui)運動(dong)(dong)時(shi),密(mi)封(feng)圈表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)(mian),磨(mo)(mo)(mo)料(liao)磨(mo)(mo)(mo)具(ju)研(yan)究部分和密(mi)封(feng)面(mian)(mian)(mian)(mian)(mian)之間(jian)的(de)(de)(de)滑(hua)動(dong)(dong)或滾動(dong)(dong),切斷(duan)密(mi)封(feng)圈上薄(bo)薄(bo)的(de)(de)(de)一層金(jin)屬表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)(mian)。密(mi)封(feng)凸峰部分的(de)(de)(de)圈,表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)(mian)研(yan)磨(mo)(mo)(mo),然后逐漸達(da)到(dao)所(suo)要求的(de)(de)(de)幾何形狀(zhuang)。不僅是金(jin)屬磨(mo)(mo)(mo)料(liao)的(de)(de)(de)研(yan)磨(mo)(mo)(mo)加工,以及化學(xue)作用。研(yan)磨(mo)(mo)(mo)油可(ke)使加工表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)(mian)形成(cheng)的(de)(de)(de)氧化膜,從而(er)加快(kuai)研(yan)磨(mo)(mo)(mo)過(guo)程(cheng)。地面(mian)(mian)(mian)(mian)(mian)運動(dong)(dong)相(xiang)對(dui)運動(dong)(dong)的(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)(mian)和密(mi)封(feng)圈密(mi)封(feng)圈的(de)(de)(de)研(yan)究,對(dui)每個(ge)點(dian)的(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)(mian)上的(de)(de)(de)道路和相(xiang)對(dui)滑(hua)動(dong)(dong)的(de)(de)(de)研(yan)究應該是一樣的(de)(de)(de)。和相(xiang)對(dui)運動(dong)(dong)方(fang)向(xiang)改變。改變密(mi)封(feng)環(huan)內的(de)(de)(de)每個(ge)粒子的(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)(mian)上運動(dong)(dong)的(de)(de)(de)方(fang)向(xiang)不會重復他們的(de)(de)(de)軌跡,以避免(mian)磨(mo)(mo)(mo)損明顯(xian)增(zeng)加了密(mi)封(feng)環(huan)的(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)(mian)粗糙(cao)度。此外,運動(dong)(dong)方(fang)向(xiang)的(de)(de)(de)改變不能使磨(mo)(mo)(mo)粒分布比較均勻(yun),且均勻(yun)切斷(duan)金(jin)屬密(mi)封(feng)環(huan)的(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)(mian)。

  隴縣機械密封研(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)是(shi)利用涂(tu)敷或者壓(ya)嵌(qian)游離(li)磨(mo)(mo)(mo)(mo)粒(li)(li)與(yu)研(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)劑的(de)(de)(de)(de)(de)混合物(wu),在(zai)(zai)一定(ding)剛性(xing)的(de)(de)(de)(de)(de)軟質研(yan)(yan)(yan)(yan)具(ju)(ju)(ju)上,通過研(yan)(yan)(yan)(yan)具(ju)(ju)(ju)與(yu)工(gong)件(jian)(jian)向磨(mo)(mo)(mo)(mo)料(liao)施加(jia)一定(ding)壓(ya)力(li),磨(mo)(mo)(mo)(mo)料(liao)滾(gun)(gun)動(dong)與(yu)滑(hua)動(dong),從(cong)被研(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)工(gong)件(jian)(jian)上去除極薄的(de)(de)(de)(de)(de)余量(liang),以(yi)提(ti)高工(gong)件(jian)(jian)的(de)(de)(de)(de)(de)精度和降(jiang)低表(biao)(biao)面(mian)(mian)粗糙度值得加(jia)工(gong)方法。按(an)研(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)時(shi)有無研(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)液(ye)可分為(wei)干研(yan)(yan)(yan)(yan)與(yu)濕研(yan)(yan)(yan)(yan)。研(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)過程中(zhong),在(zai)(zai)研(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)壓(ya)力(li)下,眾多(duo)的(de)(de)(de)(de)(de)磨(mo)(mo)(mo)(mo)料(liao)微(wei)(wei)(wei)(wei)粒(li)(li)進行(xing)微(wei)(wei)(wei)(wei)量(liang)切削。對(dui)工(gong)件(jian)(jian)表(biao)(biao)面(mian)(mian)進行(xing)擠壓(ya)、刻劃、滑(hua)擦(ca);在(zai)(zai)研(yan)(yan)(yan)(yan)具(ju)(ju)(ju)運動(dong)中(zhong)當研(yan)(yan)(yan)(yan)具(ju)(ju)(ju)壓(ya)嵌(qian)的(de)(de)(de)(de)(de)磨(mo)(mo)(mo)(mo)粒(li)(li)脫落后及液(ye)中(zhong)磨(mo)(mo)(mo)(mo)粒(li)(li)相對(dui)工(gong)件(jian)(jian)發生滾(gun)(gun)動(dong)。研(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)過程中(zhong),在(zai)(zai)研(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)壓(ya)力(li)的(de)(de)(de)(de)(de)作用下,眾多(duo)磨(mo)(mo)(mo)(mo)粒(li)(li)進行(xing)微(wei)(wei)(wei)(wei)量(liang)切削,同時(shi)被研(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)表(biao)(biao)面(mian)(mian)發生微(wei)(wei)(wei)(wei)小起(qi)伏(fu)的(de)(de)(de)(de)(de)塑性(xing)變形,并且被加(jia)入的(de)(de)(de)(de)(de)諸如硬(ying)脂酸(suan)、油酸(suan)、脂肪酸(suan)等(deng)活(huo)性(xing)物(wu)質與(yu)被研(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)表(biao)(biao)面(mian)(mian)起(qi)化學作用。隨著研(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)加(jia)工(gong)的(de)(de)(de)(de)(de)進行(xing),磨(mo)(mo)(mo)(mo)具(ju)(ju)(ju)與(yu)工(gong)件(jian)(jian)表(biao)(biao)面(mian)(mian)間更趨貼(tie)近,其(qi)間充滿了微(wei)(wei)(wei)(wei)屑與(yu)破碎(sui)磨(mo)(mo)(mo)(mo)料(liao)的(de)(de)(de)(de)(de)碎(sui)渣,堵(du)塞了研(yan)(yan)(yan)(yan)具(ju)(ju)(ju)表(biao)(biao)面(mian)(mian),對(dui)工(gong)件(jian)(jian)表(biao)(biao)面(mian)(mian)起(qi)滑(hua)擦(ca)作用。所以(yi),研(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)加(jia)工(gong)的(de)(de)(de)(de)(de)實質是(shi)磨(mo)(mo)(mo)(mo)粒(li)(li)的(de)(de)(de)(de)(de)微(wei)(wei)(wei)(wei)量(liang)切削、研(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)表(biao)(biao)面(mian)(mian)微(wei)(wei)(wei)(wei)小起(qi)伏(fu)的(de)(de)(de)(de)(de)塑性(xing)流動(dong)、表(biao)(biao)面(mian)(mian)活(huo)性(xing)物(wu)質的(de)(de)(de)(de)(de)化學作用及研(yan)(yan)(yan)(yan)具(ju)(ju)(ju)堵(du)塞物(wu)與(yu)工(gong)件(jian)(jian)表(biao)(biao)面(mian)(mian)滑(hua)擦(ca)作用的(de)(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隴縣機械密封將熱量傳(chuan)(chuan)給軸承,使軸承溫度(du)升(sheng)高。為了控制傳(chuan)(chuan)熱,所以密封的水也起(qi)到冷卻作用。


  隴縣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縣機械密封低壓(ya)側(大氣)將清水(shui)(shui)、蒸(zheng)汽等(deng)冷(leng)卻(que)流體直接引入密(mi)(mi)(mi)封端泄(xie)(xie)露(lu)處的一種(zhong)冷(leng)卻(que)方式(shi),也稱(cheng)急(ji)(ji)冷(leng),急(ji)(ji)冷(leng)不(bu)僅冷(leng)卻(que)*,還(huan)能將密(mi)(mi)(mi)封端面周圍的雜質及泄(xie)(xie)露(lu)液帶走(zou),急(ji)(ji)冷(leng)液其壓(ya)力比密(mi)(mi)(mi)封介(jie)質壓(ya)力低。急(ji)(ji)冷(leng)液應盡量采用軟(ruan)水(shui)(shui),以防止(zhi)水(shui)(shui)垢(gou)產生破壞(huai)密(mi)(mi)(mi)封端面。當密(mi)(mi)(mi)封流體為易(yi)凝(ning)固、易(yi)結(jie)晶時(shi),可用蒸(zheng)汽、溶(rong)劑等(deng)防止(zhi)流體凝(ning)結(jie)。
