上(shang)一篇我(wo)們講(jiang)了,水(shui)環泵(beng)(beng)的(de)(de)(de)(de)結(jie)構和原理接(jie)下(xia)(xia)我(wo)們就(jiu)來總結(jie)一下(xia)(xia)水(shui)環真(zhen)空泵(beng)(beng)的(de)(de)(de)(de)優(you)缺點。 一.水(shui)環真(zhen)空泵(beng)(beng)的(de)(de)(de)(de)優(you)點 1)結(jie)構簡單,制(zhi)造精度(du)(du)不高(gao),易于(yu)(yu)加工。 2)結(jie)構緊湊,泵(beng)(beng)轉(zhuan)數高(gao),一般無(wu)需減速裝(zhuang)置(zhi)即可直接(jie)與電動機連(lian)接(jie)。因(yin)(yin)此(ci),在(zai)框架尺寸(cun)小(xiao)的(de)(de)(de)(de)情況下(xia)(xia),可以獲(huo)得大的(de)(de)(de)(de)排氣(qi)(qi)(qi)量(liang),并(bing)且占地面積也(ye)小(xiao)。 3)壓(ya)縮(suo)氣(qi)(qi)(qi)體基本上(shang)是(shi)(shi)等溫(wen)的(de)(de)(de)(de),也(ye)就(jiu)是(shi)(shi)說,壓(ya)縮(suo)氣(qi)(qi)(qi)體的(de)(de)(de)(de)溫(wen)度(du)(du)變化(hua)很(hen)小(xiao)。 4)由于(yu)(yu)在(zai)泵(beng)(beng)腔中沒(mei)有金屬摩擦表(biao)面,因(yin)(yin)此(ci)無(wu)需潤(run)滑泵(beng)(beng),并(bing)且磨損(sun)很(hen)小(xiao)。旋轉(zhuan)部(bu)分(fen)和固定(ding)(ding)部(bu)分(fen)之間(jian)的(de)(de)(de)(de)密封可以直接(jie)通過(guo)水(shui)封完成。 5)吸力(li)均勻,運行(xing)穩定(ding)(ding)可靠,操(cao)作簡單,維修方便。 二.水(shui)環式真(zhen)空泵(beng)(beng)的(de)(de)(de)(de)缺點 1)低(di)效率(lv),通常為(wei)(wei)30左(zuo)右,最好達到(dao)(dao)50。 2)真(zhen)空度(du)(du)低(di),這(zhe)不僅是(shi)(shi)由于(yu)(yu)結(jie)構上(shang)的(de)(de)(de)(de)限(xian)制(zhi),而且更重要的(de)(de)(de)(de)是(shi)(shi),它受到(dao)(dao)工作流體的(de)(de)(de)(de)飽和蒸氣(qi)(qi)(qi)壓(ya)的(de)(de)(de)(de)限(xian)制(zhi)。 由于(yu)(yu)水(shui)環泵(beng)(beng)中的(de)(de)(de)(de)氣(qi)(qi)(qi)體壓(ya)縮(suo)是(shi)(shi)等溫(wen)的(de)(de)(de)(de),因(yin)(yin)此(ci)可以泵(beng)(beng)送(song)易燃(ran)易爆氣(qi)(qi)(qi)體。因(yin)(yin)為(wei)(wei)沒(mei)有排氣(qi)(qi)(qi)門(men),也(ye)沒(mei)有摩擦表(biao)面,所以它可以抽(chou)出(chu)含塵氣(qi)(qi)(qi)體,可冷(leng)凝氣(qi)(qi)(qi)體和氣(qi)(qi)(qi)水(shui)混合物。具有這(zhe)些突出(chu)的(de)(de)(de)(de)特性(xing),盡管效率(lv)低(di)下(xia)(xia),但仍被廣泛使用。
