離心泵(beng)(beng)(beng)有很多不(bu)同(tong)的類型(xing)，對(dui)于不(bu)同(tong)液體需(xu)要選(xuan)擇(ze)(ze)不(bu)同(tong)的離心泵(beng)(beng)(beng)，液體粘(zhan)度(du)不(bu)大(da)(da)(da)、流量較大(da)(da)(da)、揚程不(bu)高(gao)時，宜選(xuan)用(yong)往復泵(beng)(beng)(beng)；液體粘(zhan)度(du)較大(da)(da)(da)、流量較小(xiao)、揚程不(bu)高(gao)或含(han)有氣泡時，可選(xuan)用(yong)旋(xuan)渦泵(beng)(beng)(beng)；液體粘(zhan)度(du)較大(da)(da)(da)、流量較小(xiao)、揚程較高(gao)時，宜選(xuan)用(yong)轉子(zi)泵(beng)(beng)(beng)。 理解類型(xing)的選(xuan)擇(ze)(ze)是(shi)最(zui)基本的，只有正確選(xuan)擇(ze)(ze)才能(neng)使得正常運轉，但是(shi)我們在使用(yong)中經常會遇到突然泄漏的問題，這又是(shi)哪些原因(yin)造成(cheng)的呢？下面(mian)就(jiu)來(lai)分析一下。 1、抽空、氣蝕或較長時間憋壓，導(dao)(dao)致(zhi)密(mi)封破壞； 2、對(dui)泵(beng)(beng)(beng)實際輸出量偏小(xiao)，大(da)(da)(da)量介質(zhi)泵(beng)(beng)(beng)內(nei)循環，熱量積(ji)聚(ju)，引起(qi)(qi)介質(zhi)氣化，導(dao)(dao)致(zhi)密(mi)封失效； 3、回流量偏大(da)(da)(da)，導(dao)(dao)致(zhi)吸人管側容器(塔、釜、罐、池)底部沉(chen)渣泛起(qi)(qi)，損(sun)壞密(mi)封； 4、對(dui)較長時間停運，重新(xin)起(qi)(qi)動時沒有手動盤車，摩擦副(fu)因(yin)粘(zhan)連而扯壞密(mi)封面(mian)； 5、介質(zhi)中腐(fu)蝕性(xing)(xing)、聚(ju)合性(xing)(xing)、結膠性(xing)(xing)物(wu)質(zhi)增多； 6、環境溫(wen)度(du)急劇變(bian)化； 7、工況頻繁變(bian)化或調整； 8、突然停電或故障停機等。 當遇到突然泄漏的問題，我們一定(ding)要正確分析，以采取對(dui)的措施，以免造成(cheng)不(bu)要的損(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?
