離心(xin)泵(beng)(beng)有(you)很多(duo)(duo)不(bu)(bu)同(tong)的(de)(de)類(lei)(lei)型,對(dui)于不(bu)(bu)同(tong)液體(ti)(ti)需要(yao)(yao)選(xuan)(xuan)擇(ze)不(bu)(bu)同(tong)的(de)(de)離心(xin)泵(beng)(beng),液體(ti)(ti)粘(zhan)度(du)不(bu)(bu)大(da)、流(liu)量(liang)(liang)(liang)較大(da)、揚(yang)程(cheng)不(bu)(bu)高(gao)時(shi),宜選(xuan)(xuan)用往復泵(beng)(beng);液體(ti)(ti)粘(zhan)度(du)較大(da)、流(liu)量(liang)(liang)(liang)較小、揚(yang)程(cheng)不(bu)(bu)高(gao)或(huo)含有(you)氣(qi)泡時(shi),可選(xuan)(xuan)用旋渦泵(beng)(beng);液體(ti)(ti)粘(zhan)度(du)較大(da)、流(liu)量(liang)(liang)(liang)較小、揚(yang)程(cheng)較高(gao)時(shi),宜選(xuan)(xuan)用轉子泵(beng)(beng)。       理(li)解類(lei)(lei)型的(de)(de)選(xuan)(xuan)擇(ze)是最基(ji)本的(de)(de),只(zhi)有(you)正確選(xuan)(xuan)擇(ze)才能(neng)使得正常運轉,但(dan)是我(wo)們在(zai)使用中(zhong)經(jing)常會遇到(dao)(dao)突(tu)然(ran)泄漏(lou)(lou)的(de)(de)問題,這又是哪些原因造成的(de)(de)呢?下面就來分(fen)(fen)析(xi)一下。    1、抽(chou)空、氣(qi)蝕(shi)或(huo)較長(chang)時(shi)間(jian)憋壓,導致密(mi)封破壞;    2、對(dui)泵(beng)(beng)實(shi)際輸出量(liang)(liang)(liang)偏小,大(da)量(liang)(liang)(liang)介(jie)(jie)質(zhi)泵(beng)(beng)內循環(huan),熱量(liang)(liang)(liang)積聚(ju),引起(qi)介(jie)(jie)質(zhi)氣(qi)化(hua)(hua),導致密(mi)封失(shi)效(xiao);    3、回流(liu)量(liang)(liang)(liang)偏大(da),導致吸人管側容器(塔、釜、罐、池)底部沉渣泛起(qi),損(sun)壞密(mi)封;    4、對(dui)較長(chang)時(shi)間(jian)停(ting)運,重新起(qi)動時(shi)沒有(you)手動盤車,摩擦副因粘(zhan)連而扯壞密(mi)封面;    5、介(jie)(jie)質(zhi)中(zhong)腐蝕(shi)性(xing)、聚(ju)合性(xing)、結膠性(xing)物質(zhi)增多(duo)(duo);    6、環(huan)境溫度(du)急劇(ju)變(bian)化(hua)(hua);    7、工況頻繁變(bian)化(hua)(hua)或(huo)調(diao)整;    8、突(tu)然(ran)停(ting)電或(huo)故障停(ting)機等。    當遇到(dao)(dao)突(tu)然(ran)泄漏(lou)(lou)的(de)(de)問題,我(wo)們一定要(yao)(yao)正確分(fen)(fen)析(xi),以(yi)采取對(dui)的(de)(de)措施,以(yi)免(mian)造成不(bu)(bu)要(yao)(yao)的(de)(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?
