離心泵(beng)(beng)有(you)(you)(you)很多不(bu)(bu)同的(de)類型，對于不(bu)(bu)同液體(ti)(ti)需要(yao)選(xuan)擇不(bu)(bu)同的(de)離心泵(beng)(beng)，液體(ti)(ti)粘(zhan)度不(bu)(bu)大(da)、流量(liang)較(jiao)大(da)、揚(yang)程(cheng)不(bu)(bu)高(gao)(gao)時，宜(yi)(yi)選(xuan)用(yong)往復(fu)泵(beng)(beng)；液體(ti)(ti)粘(zhan)度較(jiao)大(da)、流量(liang)較(jiao)小、揚(yang)程(cheng)不(bu)(bu)高(gao)(gao)或含有(you)(you)(you)氣(qi)泡時，可選(xuan)用(yong)旋渦泵(beng)(beng)；液體(ti)(ti)粘(zhan)度較(jiao)大(da)、流量(liang)較(jiao)小、揚(yang)程(cheng)較(jiao)高(gao)(gao)時，宜(yi)(yi)選(xuan)用(yong)轉子泵(beng)(beng)。 理解類型的(de)選(xuan)擇是最基本的(de)，只有(you)(you)(you)正確選(xuan)擇才能使(shi)得正常運轉，但是我們在使(shi)用(yong)中(zhong)經常會遇到(dao)突(tu)然泄(xie)漏的(de)問(wen)題，這(zhe)又(you)是哪些(xie)原(yuan)因造(zao)(zao)成的(de)呢？下面就來分析一(yi)下。 1、抽空、氣(qi)蝕(shi)或較(jiao)長(chang)時間憋壓，導(dao)致(zhi)密封(feng)破(po)壞(huai)； 2、對泵(beng)(beng)實際輸出量(liang)偏小，大(da)量(liang)介質(zhi)(zhi)泵(beng)(beng)內(nei)循(xun)環，熱(re)量(liang)積聚，引起(qi)介質(zhi)(zhi)氣(qi)化，導(dao)致(zhi)密封(feng)失(shi)效； 3、回流量(liang)偏大(da)，導(dao)致(zhi)吸人管側容器(qi)(塔、釜、罐、池)底(di)部(bu)沉渣泛起(qi)，損(sun)壞(huai)密封(feng)； 4、對較(jiao)長(chang)時間停(ting)(ting)運，重新起(qi)動時沒有(you)(you)(you)手動盤車，摩(mo)擦(ca)副(fu)因粘(zhan)連(lian)而扯壞(huai)密封(feng)面； 5、介質(zhi)(zhi)中(zhong)腐蝕(shi)性、聚合性、結(jie)膠性物質(zhi)(zhi)增(zeng)多； 6、環境溫(wen)度急劇變化； 7、工(gong)況頻(pin)繁變化或調整； 8、突(tu)然停(ting)(ting)電或故障停(ting)(ting)機等。 當(dang)遇到(dao)突(tu)然泄(xie)漏的(de)問(wen)題，我們一(yi)定(ding)要(yao)正確分析，以(yi)采取對的(de)措施，以(yi)免(mian)造(zao)(zao)成不(bu)(bu)要(yao)的(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
