離心泵(beng)(beng)(beng)有很多不(bu)(bu)同的(de)類型(xing)(xing)，對于不(bu)(bu)同液體(ti)需要(yao)選(xuan)(xuan)(xuan)擇不(bu)(bu)同的(de)離心泵(beng)(beng)(beng)，液體(ti)粘度不(bu)(bu)大(da)、流(liu)量(liang)(liang)較(jiao)大(da)、揚程(cheng)不(bu)(bu)高(gao)(gao)時(shi)(shi)(shi)，宜選(xuan)(xuan)(xuan)用(yong)(yong)往復泵(beng)(beng)(beng)；液體(ti)粘度較(jiao)大(da)、流(liu)量(liang)(liang)較(jiao)小(xiao)、揚程(cheng)不(bu)(bu)高(gao)(gao)或(huo)含有氣(qi)泡(pao)時(shi)(shi)(shi)，可選(xuan)(xuan)(xuan)用(yong)(yong)旋(xuan)渦泵(beng)(beng)(beng)；液體(ti)粘度較(jiao)大(da)、流(liu)量(liang)(liang)較(jiao)小(xiao)、揚程(cheng)較(jiao)高(gao)(gao)時(shi)(shi)(shi)，宜選(xuan)(xuan)(xuan)用(yong)(yong)轉(zhuan)(zhuan)子泵(beng)(beng)(beng)。 理解類型(xing)(xing)的(de)選(xuan)(xuan)(xuan)擇是(shi)(shi)最基本的(de)，只(zhi)有正確選(xuan)(xuan)(xuan)擇才能(neng)使(shi)得正常運轉(zhuan)(zhuan)，但是(shi)(shi)我們在使(shi)用(yong)(yong)中經常會遇到突然(ran)泄(xie)漏(lou)的(de)問題(ti)，這又是(shi)(shi)哪(na)些原因(yin)造成的(de)呢？下面就來分(fen)析一(yi)下。 1、抽空、氣(qi)蝕(shi)或(huo)較(jiao)長時(shi)(shi)(shi)間憋(bie)壓(ya)，導致(zhi)密(mi)(mi)封破壞； 2、對泵(beng)(beng)(beng)實際輸出量(liang)(liang)偏小(xiao)，大(da)量(liang)(liang)介質泵(beng)(beng)(beng)內循環，熱量(liang)(liang)積聚，引起介質氣(qi)化，導致(zhi)密(mi)(mi)封失效； 3、回(hui)流(liu)量(liang)(liang)偏大(da)，導致(zhi)吸(xi)人管側容器(塔、釜、罐、池)底部沉渣泛(fan)起，損(sun)壞密(mi)(mi)封； 4、對較(jiao)長時(shi)(shi)(shi)間停運，重新起動(dong)時(shi)(shi)(shi)沒(mei)有手動(dong)盤車，摩擦(ca)副因(yin)粘連而扯壞密(mi)(mi)封面； 5、介質中腐蝕(shi)性(xing)、聚合(he)性(xing)、結(jie)膠性(xing)物質增多； 6、環境溫度急劇(ju)變(bian)化； 7、工況(kuang)頻繁(fan)變(bian)化或(huo)調(diao)整； 8、突然(ran)停電或(huo)故障停機等。 當遇到突然(ran)泄(xie)漏(lou)的(de)問題(ti)，我們一(yi)定要(yao)正確分(fen)析，以采取對的(de)措施，以免造成不(bu)(bu)要(yao)的(de)損(sun)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
