離心泵(beng)(beng)有(you)很多不(bu)(bu)同(tong)的(de)(de)類(lei)型,對于(yu)不(bu)(bu)同(tong)液體需要(yao)選(xuan)擇不(bu)(bu)同(tong)的(de)(de)離心泵(beng)(beng),液體粘(zhan)度(du)不(bu)(bu)大、流(liu)(liu)量(liang)較(jiao)(jiao)大、揚(yang)(yang)程不(bu)(bu)高(gao)(gao)時(shi)(shi)(shi),宜選(xuan)用(yong)(yong)往復泵(beng)(beng);液體粘(zhan)度(du)較(jiao)(jiao)大、流(liu)(liu)量(liang)較(jiao)(jiao)小(xiao)、揚(yang)(yang)程不(bu)(bu)高(gao)(gao)或(huo)含有(you)氣(qi)泡時(shi)(shi)(shi),可選(xuan)用(yong)(yong)旋渦泵(beng)(beng);液體粘(zhan)度(du)較(jiao)(jiao)大、流(liu)(liu)量(liang)較(jiao)(jiao)小(xiao)、揚(yang)(yang)程較(jiao)(jiao)高(gao)(gao)時(shi)(shi)(shi),宜選(xuan)用(yong)(yong)轉子泵(beng)(beng)。 理(li)解類(lei)型的(de)(de)選(xuan)擇是(shi)最基本的(de)(de),只有(you)正(zheng)確選(xuan)擇才能使得(de)正(zheng)常(chang)運轉,但是(shi)我(wo)們(men)在使用(yong)(yong)中經常(chang)會(hui)遇(yu)到(dao)突(tu)然(ran)泄(xie)漏(lou)(lou)的(de)(de)問題,這又是(shi)哪(na)些原因造成的(de)(de)呢?下(xia)面就來分(fen)析一(yi)下(xia)。 1、抽空(kong)、氣(qi)蝕或(huo)較(jiao)(jiao)長時(shi)(shi)(shi)間憋壓,導(dao)致(zhi)密(mi)封(feng)破壞; 2、對泵(beng)(beng)實際輸出量(liang)偏(pian)小(xiao),大量(liang)介質泵(beng)(beng)內循環,熱量(liang)積聚,引起(qi)(qi)介質氣(qi)化,導(dao)致(zhi)密(mi)封(feng)失(shi)效; 3、回流(liu)(liu)量(liang)偏(pian)大,導(dao)致(zhi)吸人管側(ce)容器(qi)(塔、釜、罐(guan)、池)底部(bu)沉渣泛起(qi)(qi),損(sun)壞密(mi)封(feng); 4、對較(jiao)(jiao)長時(shi)(shi)(shi)間停運,重新起(qi)(qi)動時(shi)(shi)(shi)沒有(you)手(shou)動盤(pan)車,摩擦副因粘(zhan)連而(er)扯壞密(mi)封(feng)面; 5、介質中腐(fu)蝕性、聚合性、結膠性物質增多; 6、環境溫度(du)急劇(ju)變化; 7、工況頻(pin)繁變化或(huo)調(diao)整; 8、突(tu)然(ran)停電或(huo)故障停機等。 當遇(yu)到(dao)突(tu)然(ran)泄(xie)漏(lou)(lou)的(de)(de)問題,我(wo)們(men)一(yi)定要(yao)正(zheng)確分(fen)析,以采取對的(de)(de)措施,以免造成不(bu)(bu)要(yao)的(de)(de)損(sun)失(shi)。

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?
