離心泵(beng)(beng)有(you)很多(duo)不(bu)同(tong)的(de)(de)(de)類型(xing),對于不(bu)同(tong)液體(ti)需要選擇不(bu)同(tong)的(de)(de)(de)離心泵(beng)(beng),液體(ti)粘(zhan)度(du)(du)不(bu)大、流量較(jiao)(jiao)(jiao)大、揚程(cheng)(cheng)不(bu)高時(shi),宜(yi)選用往復泵(beng)(beng);液體(ti)粘(zhan)度(du)(du)較(jiao)(jiao)(jiao)大、流量較(jiao)(jiao)(jiao)小(xiao)、揚程(cheng)(cheng)不(bu)高或含有(you)氣(qi)泡(pao)時(shi),可選用旋渦泵(beng)(beng);液體(ti)粘(zhan)度(du)(du)較(jiao)(jiao)(jiao)大、流量較(jiao)(jiao)(jiao)小(xiao)、揚程(cheng)(cheng)較(jiao)(jiao)(jiao)高時(shi),宜(yi)選用轉子泵(beng)(beng)。 理解類型(xing)的(de)(de)(de)選擇是(shi)最(zui)基本(ben)的(de)(de)(de),只有(you)正(zheng)確(que)選擇才能(neng)使得(de)正(zheng)常(chang)運轉,但是(shi)我(wo)(wo)們在使用中經常(chang)會遇(yu)到(dao)突然(ran)泄漏的(de)(de)(de)問題,這又是(shi)哪些原因(yin)造(zao)成(cheng)的(de)(de)(de)呢?下面就(jiu)來分(fen)析一下。 1、抽空、氣(qi)蝕或較(jiao)(jiao)(jiao)長時(shi)間(jian)憋壓,導致(zhi)密(mi)封(feng)(feng)破壞; 2、對泵(beng)(beng)實際輸出量偏(pian)小(xiao),大量介(jie)質泵(beng)(beng)內循環(huan),熱(re)量積(ji)聚(ju),引起介(jie)質氣(qi)化(hua),導致(zhi)密(mi)封(feng)(feng)失效; 3、回流量偏(pian)大,導致(zhi)吸(xi)人(ren)管(guan)側容器(塔、釜(fu)、罐、池)底(di)部沉渣泛起,損壞密(mi)封(feng)(feng); 4、對較(jiao)(jiao)(jiao)長時(shi)間(jian)停(ting)運,重(zhong)新(xin)起動時(shi)沒有(you)手動盤(pan)車,摩擦副因(yin)粘(zhan)連而扯(che)壞密(mi)封(feng)(feng)面; 5、介(jie)質中腐蝕性(xing)(xing)、聚(ju)合性(xing)(xing)、結膠性(xing)(xing)物(wu)質增多(duo); 6、環(huan)境溫度(du)(du)急劇變化(hua); 7、工況頻繁變化(hua)或調(diao)整; 8、突然(ran)停(ting)電或故障停(ting)機等(deng)。 當遇(yu)到(dao)突然(ran)泄漏的(de)(de)(de)問題,我(wo)(wo)們一定要正(zheng)確(que)分(fen)析,以采(cai)取對的(de)(de)(de)措施,以免造(zao)成(cheng)不(bu)要的(de)(de)(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,則可以卸下水環真空泵過濾器。 5.更換水環真空泵口環,調整軸向間隙,以防止葉輪口環和軸向間隙不合適。使用時,請根據?
