離心泵(beng)有(you)(you)(you)很多(duo)不(bu)同(tong)的類(lei)型(xing),對(dui)(dui)(dui)于不(bu)同(tong)液(ye)體(ti)(ti)需要(yao)(yao)選擇不(bu)同(tong)的離心泵(beng),液(ye)體(ti)(ti)粘(zhan)度(du)不(bu)大(da)、流(liu)量較(jiao)(jiao)大(da)、揚程(cheng)不(bu)高(gao)時,宜(yi)選用往復泵(beng);液(ye)體(ti)(ti)粘(zhan)度(du)較(jiao)(jiao)大(da)、流(liu)量較(jiao)(jiao)小、揚程(cheng)不(bu)高(gao)或(huo)含有(you)(you)(you)氣泡時,可選用旋渦泵(beng);液(ye)體(ti)(ti)粘(zhan)度(du)較(jiao)(jiao)大(da)、流(liu)量較(jiao)(jiao)小、揚程(cheng)較(jiao)(jiao)高(gao)時,宜(yi)選用轉(zhuan)子(zi)泵(beng)。 理(li)解類(lei)型(xing)的選擇是最基本的,只有(you)(you)(you)正(zheng)確選擇才能使得正(zheng)常(chang)運(yun)轉(zhuan),但是我們在使用中(zhong)經(jing)常(chang)會(hui)遇(yu)到突然(ran)泄漏的問題,這又是哪些原因(yin)造成(cheng)(cheng)的呢(ni)?下面(mian)就來(lai)分(fen)析(xi)一下。 1、抽空、氣蝕(shi)或(huo)較(jiao)(jiao)長時間(jian)(jian)憋壓(ya),導(dao)(dao)致(zhi)密(mi)(mi)封(feng)(feng)破(po)壞(huai); 2、對(dui)(dui)(dui)泵(beng)實際輸出量偏小,大(da)量介質(zhi)(zhi)泵(beng)內(nei)循環,熱量積聚,引起(qi)介質(zhi)(zhi)氣化,導(dao)(dao)致(zhi)密(mi)(mi)封(feng)(feng)失效(xiao); 3、回流(liu)量偏大(da),導(dao)(dao)致(zhi)吸人管(guan)側容(rong)器(qi)(塔、釜、罐、池)底部沉渣泛起(qi),損(sun)(sun)壞(huai)密(mi)(mi)封(feng)(feng); 4、對(dui)(dui)(dui)較(jiao)(jiao)長時間(jian)(jian)停運(yun),重新起(qi)動時沒有(you)(you)(you)手動盤車,摩擦副因(yin)粘(zhan)連而扯(che)壞(huai)密(mi)(mi)封(feng)(feng)面(mian); 5、介質(zhi)(zhi)中(zhong)腐蝕(shi)性、聚合性、結膠性物(wu)質(zhi)(zhi)增(zeng)多(duo); 6、環境溫(wen)度(du)急劇變(bian)化; 7、工況頻繁變(bian)化或(huo)調整; 8、突然(ran)停電或(huo)故障(zhang)停機(ji)等(deng)。 當(dang)遇(yu)到突然(ran)泄漏的問題,我們一定要(yao)(yao)正(zheng)確分(fen)析(xi),以采取對(dui)(dui)(dui)的措施(shi),以免造成(cheng)(cheng)不(bu)要(yao)(yao)的損(sun)(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,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?
