離心泵(beng)有(you)很(hen)多不(bu)(bu)同(tong)(tong)的(de)類(lei)型(xing)(xing),對(dui)于(yu)不(bu)(bu)同(tong)(tong)液體(ti)需(xu)要選(xuan)擇不(bu)(bu)同(tong)(tong)的(de)離心泵(beng),液體(ti)粘(zhan)度(du)不(bu)(bu)大(da)、流(liu)(liu)量較(jiao)大(da)、揚程不(bu)(bu)高(gao)時,宜選(xuan)用(yong)往復泵(beng);液體(ti)粘(zhan)度(du)較(jiao)大(da)、流(liu)(liu)量較(jiao)小、揚程不(bu)(bu)高(gao)或(huo)含有(you)氣(qi)(qi)泡時,可選(xuan)用(yong)旋渦泵(beng);液體(ti)粘(zhan)度(du)較(jiao)大(da)、流(liu)(liu)量較(jiao)小、揚程較(jiao)高(gao)時,宜選(xuan)用(yong)轉(zhuan)子泵(beng)。 理解類(lei)型(xing)(xing)的(de)選(xuan)擇是(shi)最(zui)基(ji)本的(de),只有(you)正確選(xuan)擇才能使(shi)得正常(chang)(chang)運轉(zhuan),但是(shi)我們在(zai)使(shi)用(yong)中經常(chang)(chang)會遇到突(tu)然泄漏的(de)問題,這又(you)是(shi)哪些原因(yin)造(zao)成(cheng)的(de)呢(ni)?下(xia)面(mian)就來分(fen)析一下(xia)。 1、抽空、氣(qi)(qi)蝕或(huo)較(jiao)長時間憋壓,導致(zhi)密(mi)封破壞(huai); 2、對(dui)泵(beng)實際輸出量偏小,大(da)量介(jie)質泵(beng)內循環,熱量積聚,引起介(jie)質氣(qi)(qi)化,導致(zhi)密(mi)封失效; 3、回流(liu)(liu)量偏大(da),導致(zhi)吸人管側容器(qi)(塔、釜、罐、池)底部沉渣(zha)泛起,損壞(huai)密(mi)封; 4、對(dui)較(jiao)長時間停(ting)運,重新(xin)起動時沒(mei)有(you)手動盤車,摩擦副因(yin)粘(zhan)連而扯壞(huai)密(mi)封面(mian); 5、介(jie)質中腐蝕性、聚合性、結膠性物質增多; 6、環境溫度(du)急(ji)劇變化; 7、工(gong)況頻繁變化或(huo)調整; 8、突(tu)然停(ting)電或(huo)故障停(ting)機等。 當遇到突(tu)然泄漏的(de)問題,我們一定要正確分(fen)析,以采取對(dui)的(de)措施,以免造(zao)成(cheng)不(bu)(bu)要的(de)損失。

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?
