眾所(suo)周知,對于各種(zhong)真(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)性能(neng),都有規定的(de)(de)(de)(de)(de)(de)(de)測試方法來測試該性能(neng)的(de)(de)(de)(de)(de)(de)(de)性能(neng),主要(yao)性能(neng)是極限(xian)壓(ya)力,流(liu)(liu)量(liang)(liang)(liang)(liang)和(he)抽速。這次,小編打算討論螺桿真(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)流(liu)(liu)量(liang)(liang)(liang)(liang),例如(ru)(ru)如(ru)(ru)何控制(zhi)其(qi)流(liu)(liu)量(liang)(liang)(liang)(liang),流(liu)(liu)量(liang)(liang)(liang)(liang)不(bu)(bu)足的(de)(de)(de)(de)(de)(de)(de)原因以(yi)(yi)及如(ru)(ru)何消(xiao)除此問題。相(xiang)信(xin)許多(duo)用(yong)(yong)(yong)戶對這些問題感到困惑(huo),不(bu)(bu)用(yong)(yong)(yong)擔心(xin),請(qing)跟隨(sui)螺桿真(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)廠家進行(xing)了解。 首先,讓我(wo)們(men)簡單(dan)介紹一下真(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)主要(yao)性能(neng)的(de)(de)(de)(de)(de)(de)(de)概念。 1.極限(xian)壓(ya)力。真(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)與檢測容器(qi)相(xiang)連(lian),放置待測氣(qi)體(ti)(ti)后,連(lian)續長時(shi)間抽氣(qi)。當容器(qi)的(de)(de)(de)(de)(de)(de)(de)氣(qi)壓(ya)不(bu)(bu)再降低并且壓(ya)力保持在一定值時(shi),次級壓(ya)力就(jiu)是泵(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)極限(xian)壓(ya)力。 2.流(liu)(liu)量(liang)(liang)(liang)(liang)。在真(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)吸入(ru)口,每(mei)單(dan)位(wei)時(shi)間的(de)(de)(de)(de)(de)(de)(de)氣(qi)體(ti)(ti)流(liu)(liu)量(liang)(liang)(liang)(liang)稱(cheng)為泵(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)流(liu)(liu)量(liang)(liang)(liang)(liang)。在真(zhen)(zhen)空(kong)(kong)(kong)技(ji)術中,流(liu)(liu)量(liang)(liang)(liang)(liang)單(dan)位(wei)以(yi)(yi)壓(ya)力*體(ti)(ti)積(ji)/時(shi)間表(biao)示,即Pa.m3/s或Pa.m3/h。通常,泵(beng)(beng)會給出(chu)流(liu)(liu)量(liang)(liang)(liang)(liang)與入(ru)口壓(ya)力的(de)(de)(de)(de)(de)(de)(de)關系圖。 3.抽速。在真(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)吸入(ru)口,每(mei)單(dan)位(wei)時(shi)間流(liu)(liu)動的(de)(de)(de)(de)(de)(de)(de)氣(qi)體(ti)(ti)量(liang)(liang)(liang)(liang)稱(cheng)為泵(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)抽氣(qi)速率(lv)。即,通過(guo)將流(liu)(liu)量(liang)(liang)(liang)(liang)QA(Pa.m3/s)除以(yi)(yi)測試罩中的(de)(de)(de)(de)(de)(de)(de)氣(qi)體(ti)(ti)A的(de)(de)(de)(de)(de)(de)(de)分(fen)壓(ya)pA而獲得氣(qi)體(ti)(ti)A的(de)(de)(de)(de)(de)(de)(de)泵(beng)(beng)送速度(du)sA(m3/s)。典型(xing)(xing)的(de)(de)(de)(de)(de)(de)(de)真(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)抽氣(qi)速率(lv)與氣(qi)體(ti)(ti)類型(xing)(xing)有關。給定的(de)(de)(de)(de)(de)(de)(de)抽氣(qi)速率(lv)表(biao)示某種(zhong)氣(qi)體(ti)(ti)的(de)(de)(de)(de)(de)(de)(de)抽氣(qi)速率(lv)。如(ru)(ru)果沒(mei)有特殊指示,則使(shi)用(yong)(yong)(yong)多(duo)指抽吸。 正確控制(zhi)螺桿真(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)流(liu)(liu)量(liang)(liang)(liang)(liang)不(bu)(bu)僅(jin)可(ke)以(yi)(yi)為設備(bei)提供良好的(de)(de)(de)(de)(de)(de)(de)保護(hu),還可(ke)以(yi)(yi)提高使(shi)用(yong)(yong)(yong)率(lv)。那(nei)么(me),該怎么(me)做呢(ni)? 1,速度(du)控制(zhi) 葉輪(lun)速度(du)的(de)(de)(de)(de)(de)(de)(de)變化(hua)會改變螺桿真(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)流(liu)(liu)量(liang)(liang)(liang)(liang)曲線,并且曲線的(de)(de)(de)(de)(de)(de)(de)特性不(bu)(bu)會改變。隨(sui)著(zhu)速度(du)降低,曲線變平,揚程(cheng)和(he)流(liu)(liu)速降低。 2,旁通閥(fa)調整 使(shi)用(yong)(yong)(yong)與泵(beng)(beng)并聯的(de)(de)(de)(de)(de)(de)(de)中間閥(fa)。實際(ji)效果就(jiu)...

離心(xin)泵(beng)(beng)(beng)有(you)很多(duo)不(bu)同的(de)類型(xing),對(dui)于不(bu)同液(ye)體(ti)(ti)(ti)需要選(xuan)擇不(bu)同的(de)離心(xin)泵(beng)(beng)(beng),液(ye)體(ti)(ti)(ti)粘(zhan)度不(bu)大(da)、流(liu)量較大(da)、揚(yang)程不(bu)高(gao)時(shi)(shi)(shi)(shi),宜選(xuan)用往復泵(beng)(beng)(beng);液(ye)體(ti)(ti)(ti)粘(zhan)度較大(da)、流(liu)量較小(xiao)、揚(yang)程不(bu)高(gao)或(huo)(huo)含有(you)氣泡時(shi)(shi)(shi)(shi),可選(xuan)用旋渦泵(beng)(beng)(beng);液(ye)體(ti)(ti)(ti)粘(zhan)度較大(da)、流(liu)量較小(xiao)、揚(yang)程較高(gao)時(shi)(shi)(shi)(shi),宜選(xuan)用轉子泵(beng)(beng)(beng)。 理解類型(xing)的(de)選(xuan)擇是(shi)最基本的(de),只有(you)正確選(xuan)擇才能使(shi)得正常運轉,但是(shi)我們(men)在使(shi)用中經常會(hui)遇(yu)到突(tu)然(ran)泄(xie)漏的(de)問題(ti),這(zhe)又是(shi)哪些原因造(zao)成(cheng)的(de)呢?下(xia)面就來分析一下(xia)。 1、抽空、氣蝕或(huo)(huo)較長時(shi)(shi)(shi)(shi)間憋壓,導(dao)致密封破壞; 2、對(dui)泵(beng)(beng)(beng)實際(ji)輸出量偏小(xiao),大(da)量介(jie)質泵(beng)(beng)(beng)內循環,熱量積聚(ju),引起(qi)介(jie)質氣化(hua),導(dao)致密封失(shi)(shi)效; 3、回流(liu)量偏大(da),導(dao)致吸人(ren)管側容(rong)器(qi)(塔、釜、罐、池)底部沉渣(zha)泛起(qi),損壞密封; 4、對(dui)較長時(shi)(shi)(shi)(shi)間停運,重新(xin)起(qi)動時(shi)(shi)(shi)(shi)沒有(you)手動盤車,摩擦副因粘(zhan)連而扯壞密封面; 5、介(jie)質中腐蝕性、聚(ju)合性、結膠性物質增多(duo); 6、環境(jing)溫(wen)度急劇變化(hua); 7、工況(kuang)頻(pin)繁變化(hua)或(huo)(huo)調整; 8、突(tu)然(ran)停電或(huo)(huo)故障停機(ji)等。 當(dang)遇(yu)到突(tu)然(ran)泄(xie)漏的(de)問題(ti),我們(men)一定要正確分析,以(yi)采取對(dui)的(de)措施,以(yi)免(mian)造(zao)成(cheng)不(bu)要的(de)損失(shi)(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?
