離心(xin)泵(beng)有(you)(you)很多不(bu)同(tong)(tong)的(de)類(lei)型(xing),對于不(bu)同(tong)(tong)液(ye)(ye)體(ti)需(xu)要選(xuan)(xuan)擇不(bu)同(tong)(tong)的(de)離心(xin)泵(beng),液(ye)(ye)體(ti)粘(zhan)度(du)(du)不(bu)大、流(liu)(liu)量(liang)較大、揚(yang)程不(bu)高時(shi),宜選(xuan)(xuan)用往復泵(beng);液(ye)(ye)體(ti)粘(zhan)度(du)(du)較大、流(liu)(liu)量(liang)較小、揚(yang)程不(bu)高或(huo)含(han)有(you)(you)氣(qi)泡時(shi),可選(xuan)(xuan)用旋(xuan)渦(wo)泵(beng);液(ye)(ye)體(ti)粘(zhan)度(du)(du)較大、流(liu)(liu)量(liang)較小、揚(yang)程較高時(shi),宜選(xuan)(xuan)用轉(zhuan)子泵(beng)。 理解類(lei)型(xing)的(de)選(xuan)(xuan)擇是(shi)最基本(ben)的(de),只有(you)(you)正(zheng)確(que)選(xuan)(xuan)擇才(cai)能使得正(zheng)常(chang)運轉(zhuan),但是(shi)我們在使用中經(jing)常(chang)會遇(yu)到突(tu)然泄漏的(de)問題(ti),這又是(shi)哪些原因(yin)造(zao)成的(de)呢?下面(mian)就(jiu)來(lai)分(fen)析(xi)一下。 1、抽(chou)空、氣(qi)蝕或(huo)較長(chang)時(shi)間(jian)憋壓,導(dao)致(zhi)密(mi)封(feng)(feng)破壞(huai); 2、對泵(beng)實際輸(shu)出量(liang)偏小,大量(liang)介質(zhi)(zhi)(zhi)泵(beng)內循環,熱量(liang)積聚(ju),引起介質(zhi)(zhi)(zhi)氣(qi)化(hua),導(dao)致(zhi)密(mi)封(feng)(feng)失效(xiao); 3、回流(liu)(liu)量(liang)偏大,導(dao)致(zhi)吸人管側(ce)容(rong)器(塔、釜、罐、池)底部沉渣泛起,損壞(huai)密(mi)封(feng)(feng); 4、對較長(chang)時(shi)間(jian)停(ting)(ting)運,重新起動時(shi)沒有(you)(you)手動盤車,摩擦副因(yin)粘(zhan)連而扯壞(huai)密(mi)封(feng)(feng)面(mian); 5、介質(zhi)(zhi)(zhi)中腐蝕性(xing)(xing)、聚(ju)合性(xing)(xing)、結膠性(xing)(xing)物質(zhi)(zhi)(zhi)增多; 6、環境溫度(du)(du)急劇變化(hua); 7、工(gong)況頻(pin)繁變化(hua)或(huo)調整; 8、突(tu)然停(ting)(ting)電或(huo)故障停(ting)(ting)機等。 當(dang)遇(yu)到突(tu)然泄漏的(de)問題(ti),我們一定要正(zheng)確(que)分(fen)析(xi),以采取對的(de)措(cuo)施(shi),以免(mian)造(zao)成不(bu)要的(de)損失。

水環真空泵一直非常關注粗糙真空的獲得,例如真空過濾,真空水轉移,真空蒸發等。它已廣泛用于工業生產的許多過程中。 為了節約能源,有必要盡可能地節約能源。我們如何使用水環真空泵來節能? 1. 水環真空泵對角安裝,以減小彎頭或蝸殼,使水口面向水池。 2.縮短水環真空泵管道,拆除1米長的鋼管,并在10小時內節省0.21千克柴油。 3.擴大水環真空泵的出口管直徑。例如,將15米長的4米長水管替換為15厘米長的管道,并節省10公斤柴油10小時。 4.如果可以保持進水清潔,則可以卸下水環真空泵過濾器。 5.更換水環真空泵口環,調整軸向間隙,以防止葉輪口環?
