離心(xin)泵有(you)很多(duo)不(bu)同的(de)(de)(de)類(lei)型，對(dui)于不(bu)同液(ye)體(ti)需要選(xuan)擇(ze)(ze)不(bu)同的(de)(de)(de)離心(xin)泵，液(ye)體(ti)粘度不(bu)大(da)、流量較大(da)、揚程(cheng)不(bu)高時(shi)，宜(yi)選(xuan)用往復泵；液(ye)體(ti)粘度較大(da)、流量較小(xiao)、揚程(cheng)不(bu)高或含有(you)氣泡(pao)時(shi)，可選(xuan)用旋渦泵；液(ye)體(ti)粘度較大(da)、流量較小(xiao)、揚程(cheng)較高時(shi)，宜(yi)選(xuan)用轉子(zi)泵。 理解類(lei)型的(de)(de)(de)選(xuan)擇(ze)(ze)是(shi)最基本的(de)(de)(de)，只有(you)正確選(xuan)擇(ze)(ze)才能使得(de)正常運(yun)轉，但是(shi)我們在(zai)使用中經(jing)常會遇(yu)到突然泄(xie)漏的(de)(de)(de)問題，這又是(shi)哪些(xie)原因造(zao)成(cheng)的(de)(de)(de)呢？下面(mian)就來分析一下。 1、抽空(kong)、氣蝕或較長(chang)時(shi)間憋壓，導致(zhi)密封(feng)(feng)破壞(huai)； 2、對(dui)泵實際輸出(chu)量偏(pian)小(xiao)，大(da)量介質(zhi)泵內循環，熱量積聚，引起(qi)(qi)介質(zhi)氣化，導致(zhi)密封(feng)(feng)失效； 3、回流量偏(pian)大(da)，導致(zhi)吸人管(guan)側容器(塔、釜、罐(guan)、池)底部沉渣(zha)泛起(qi)(qi)，損(sun)壞(huai)密封(feng)(feng)； 4、對(dui)較長(chang)時(shi)間停運(yun)，重(zhong)新起(qi)(qi)動時(shi)沒有(you)手動盤車，摩擦(ca)副因粘連(lian)而扯(che)壞(huai)密封(feng)(feng)面(mian)； 5、介質(zhi)中腐蝕性(xing)、聚合性(xing)、結(jie)膠(jiao)性(xing)物質(zhi)增多(duo)； 6、環境溫(wen)度急劇變化； 7、工況(kuang)頻繁變化或調整； 8、突然停電或故障(zhang)停機等。 當遇(yu)到突然泄(xie)漏的(de)(de)(de)問題，我們一定要正確分析，以(yi)采取對(dui)的(de)(de)(de)措施，以(yi)免造(zao)成(cheng)不(bu)要的(de)(de)(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。
