離(li)心(xin)泵(beng)有(you)很多不(bu)同的(de)類型(xing)，對(dui)于不(bu)同液(ye)體(ti)需(xu)要(yao)選(xuan)(xuan)擇(ze)不(bu)同的(de)離(li)心(xin)泵(beng)，液(ye)體(ti)粘(zhan)度(du)不(bu)大(da)、流(liu)量(liang)(liang)較大(da)、揚程不(bu)高(gao)時(shi)(shi)，宜(yi)選(xuan)(xuan)用(yong)往復泵(beng)；液(ye)體(ti)粘(zhan)度(du)較大(da)、流(liu)量(liang)(liang)較小(xiao)、揚程不(bu)高(gao)或(huo)(huo)含(han)有(you)氣(qi)(qi)泡時(shi)(shi)，可選(xuan)(xuan)用(yong)旋渦泵(beng)；液(ye)體(ti)粘(zhan)度(du)較大(da)、流(liu)量(liang)(liang)較小(xiao)、揚程較高(gao)時(shi)(shi)，宜(yi)選(xuan)(xuan)用(yong)轉子泵(beng)。 理解類型(xing)的(de)選(xuan)(xuan)擇(ze)是最基本的(de)，只有(you)正確(que)(que)選(xuan)(xuan)擇(ze)才能使(shi)得正常(chang)運轉，但是我(wo)們在(zai)使(shi)用(yong)中經常(chang)會遇(yu)到突然泄漏的(de)問(wen)題(ti)，這又(you)是哪些(xie)原因(yin)造成(cheng)的(de)呢(ni)？下面就來(lai)分析(xi)一下。 1、抽空、氣(qi)(qi)蝕或(huo)(huo)較長時(shi)(shi)間(jian)憋壓，導致密(mi)封破壞； 2、對(dui)泵(beng)實際輸出量(liang)(liang)偏小(xiao)，大(da)量(liang)(liang)介(jie)質(zhi)泵(beng)內循環，熱量(liang)(liang)積聚，引起(qi)介(jie)質(zhi)氣(qi)(qi)化(hua)，導致密(mi)封失(shi)效； 3、回流(liu)量(liang)(liang)偏大(da)，導致吸人管側(ce)容器(塔(ta)、釜、罐、池)底(di)部沉(chen)渣泛(fan)起(qi)，損(sun)壞密(mi)封； 4、對(dui)較長時(shi)(shi)間(jian)停(ting)運，重新起(qi)動時(shi)(shi)沒有(you)手動盤(pan)車，摩擦(ca)副因(yin)粘(zhan)連(lian)而扯壞密(mi)封面； 5、介(jie)質(zhi)中腐蝕性、聚合性、結膠(jiao)性物質(zhi)增多； 6、環境溫度(du)急劇(ju)變化(hua)； 7、工況(kuang)頻繁(fan)變化(hua)或(huo)(huo)調(diao)整(zheng)； 8、突然停(ting)電(dian)或(huo)(huo)故(gu)障停(ting)機等(deng)。 當遇(yu)到突然泄漏的(de)問(wen)題(ti)，我(wo)們一定要(yao)正確(que)(que)分析(xi)，以采取對(dui)的(de)措施，以免造成(cheng)不(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
