真(zhen)(zhen)空(kong)泵(beng)(beng)使用(yong)過(guo)(guo)程中這幾個點要(yao)(yao)注意(yi)  1.真(zhen)(zhen)空(kong)泵(beng)(beng)用(yong)于(yu)(yu)抽(chou)(chou)(chou)潔凈氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti),不(bu)(bu)能(neng)抽(chou)(chou)(chou)有(you)(you)毒、易(yi)(yi)燃、易(yi)(yi)爆(bao)、腐蝕性氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)或者蒸(zheng)汽、化學品(pin)、溶劑及粉末等(deng)。如(ru)(ru)易(yi)(yi)燃氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)、含國(guo)家(jia)特(te)殊化學品(pin)規定成分的特(te)殊或高(gao)濃(nong)度(du)強酸強堿性氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)、或半導體(ti)工藝(yi)中高(gao)濃(nong)度(du)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)、有(you)(you)機(ji)溶劑、結晶氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)等(deng)。這些氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)容易(yi)(yi)使軸承失效。  2.進氣(qi)(qi)(qi)(qi)(qi)(qi)溫度(du)必(bi)須低(di)于(yu)(yu)50℃,否(fou)則(ze)在(zai)被抽(chou)(chou)(chou)真(zhen)(zhen)空(kong)室與泵(beng)(beng)進氣(qi)(qi)(qi)(qi)(qi)(qi)口(kou)之(zhi)間必(bi)須加冷阱(jing),降(jiang)溫至低(di)于(yu)(yu)50℃。  3.抽(chou)(chou)(chou)含有(you)(you)水蒸(zheng)汽的氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)時(shi)(shi),要(yao)(yao)打開氣(qi)(qi)(qi)(qi)(qi)(qi)鎮閥抽(chou)(chou)(chou)氣(qi)(qi)(qi)(qi)(qi)(qi),被抽(chou)(chou)(chou)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)水蒸(zheng)汽含量要(yao)(yao)求在(zai)23克/日以(yi)下。如(ru)(ru)果超過(guo)(guo)此(ci)極(ji)限,將(jiang)會(hui)縮短氣(qi)(qi)(qi)(qi)(qi)(qi)鎮閥壽命。  4.真(zhen)(zhen)空(kong)泵(beng)(beng)不(bu)(bu)能(neng)在(zai)腐蝕性、易(yi)(yi)燃、易(yi)(yi)爆(bao)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)或蒸(zheng)汽環境中工作,否(fou)則(ze)會(hui)有(you)(you)爆(bao)炸、火災等(deng)危險。    5.不(bu)(bu)要(yao)(yao)由一兩個人移動此(ci)泵(beng)(beng)。此(ci)由專(zhuan)業(ye)人員搬運、安裝(zhuang)、配(pei)置(zhi)、配(pei)線、操作、維(wei)護(hu)(hu)和檢查,否(fou)則(ze)會(hui)有(you)(you)觸電、受傷或者泵(beng)(beng)甚至被抽(chou)(chou)(chou)真(zhen)(zhen)空(kong)室損(sun)(sun)壞的危險。  6.不(bu)(bu)要(yao)(yao)繼續使用(yong)已經損(sun)(sun)壞的泵(beng)(beng),否(fou)則(ze)會(hui)有(you)(you)受傷、觸電甚至被抽(chou)(chou)(chou)系(xi)統損(sun)(sun)壞等(deng)危險。  7.檢查確定此(ci)泵(beng)(beng)安全(quan)接(jie)地。  8.此(ci)泵(beng)(beng)工作過(guo)(guo)程中或剛停機(ji)時(shi)(shi)不(bu)(bu)要(yao)(yao)接(jie)觸泵(beng)(beng)電機(ji)或金屬部件(因為工作時(shi)(shi)很熱,最高(gao)可(ke)能(neng)達到70℃)。如(ru)(ru)確實需要(yao)(yao)接(jie)觸,采取必(bi)要(yao)(yao)防護(hu)(hu)措施(shi)防止受傷。  9.必(bi)須安裝(zhuang)電機(ji)保(bao)護(hu)(hu)開關。  10.不(bu)(bu)要(yao)(yao)刮碰進氣(qi)(qi)(qi)(qi)(qi)(qi)口(kou)與排氣(qi)(qi)(qi)(qi)(qi)(qi)口(kou)法蘭,以(yi)免(mian)損(sun)(sun)壞法蘭口(kou),導致真(zhen)(zhen)空(kong)度(du)上不(bu)(bu)去。  11.在(zai)進氣(qi)(qi)(qi)(qi)(qi)(qi)口(kou)處(chu)裝(zhuang)截止閥。真(zhen)(zhen)空(kong)泵(beng)(beng)停止后進氣(qi)(qi)(qi)(qi)(qi)(qi)口(kou)處(chu)真(zhen)(zhen)空(kong)度(du)降(jiang)低(di),是因為排氣(qi)(qi)(qi)(qi)(qi)(qi)口(kou)處(chu)的大(da)氣(qi)(qi)(qi)(qi)(qi)(qi)返至進氣(qi)(qi)(qi)(qi)(qi)(qi)口(kou)處(chu),不(bu)(bu)是真(zhen)(zhen)空(kong)泵(beng)(beng)的原因。如(ru)(ru)要(yao)(yao)保(bao)證真(zhen)(zhen)空(kong)室內的真(zhen)(zhen)空(kong)度(du),要(yao)(yao)在(zai)真(zhen)(zhen)空(kong)...
