眾所周知,對于各種(zhong)真(zhen)空(kong)泵(beng)(beng)(beng)的(de)(de)(de)性(xing)(xing)能,都(dou)有(you)(you)規定(ding)(ding)的(de)(de)(de)測(ce)試方法(fa)來測(ce)試該性(xing)(xing)能的(de)(de)(de)性(xing)(xing)能,主要(yao)性(xing)(xing)能是極限(xian)(xian)壓(ya)(ya)力,流(liu)(liu)(liu)(liu)量(liang)和(he)抽(chou)(chou)速(su)(su)(su)(su)(su)。這次(ci),小編打算討論螺(luo)桿(gan)真(zhen)空(kong)泵(beng)(beng)(beng)的(de)(de)(de)流(liu)(liu)(liu)(liu)量(liang),例如(ru)如(ru)何(he)控制其流(liu)(liu)(liu)(liu)量(liang),流(liu)(liu)(liu)(liu)量(liang)不(bu)足的(de)(de)(de)原(yuan)因(yin)以(yi)及如(ru)何(he)消除此問題。相信許(xu)多用(yong)戶對這些問題感到困惑,不(bu)用(yong)擔心,請跟(gen)隨螺(luo)桿(gan)真(zhen)空(kong)泵(beng)(beng)(beng)廠家(jia)進行了解(jie)。 首先,讓我們簡單(dan)介紹(shao)一(yi)下真(zhen)空(kong)泵(beng)(beng)(beng)主要(yao)性(xing)(xing)能的(de)(de)(de)概念。 1.極限(xian)(xian)壓(ya)(ya)力。真(zhen)空(kong)泵(beng)(beng)(beng)與檢測(ce)容器相連,放置待測(ce)氣(qi)(qi)(qi)(qi)(qi)體(ti)后,連續長時(shi)間(jian)抽(chou)(chou)氣(qi)(qi)(qi)(qi)(qi)。當容器的(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)壓(ya)(ya)不(bu)再(zai)降低并且壓(ya)(ya)力保(bao)持在(zai)(zai)一(yi)定(ding)(ding)值時(shi),次(ci)級(ji)壓(ya)(ya)力就(jiu)是泵(beng)(beng)(beng)的(de)(de)(de)極限(xian)(xian)壓(ya)(ya)力。 2.流(liu)(liu)(liu)(liu)量(liang)。在(zai)(zai)真(zhen)空(kong)泵(beng)(beng)(beng)的(de)(de)(de)吸(xi)(xi)入口(kou),每(mei)單(dan)位(wei)時(shi)間(jian)的(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)流(liu)(liu)(liu)(liu)量(liang)稱為泵(beng)(beng)(beng)的(de)(de)(de)流(liu)(liu)(liu)(liu)量(liang)。在(zai)(zai)真(zhen)空(kong)技術中,流(liu)(liu)(liu)(liu)量(liang)單(dan)位(wei)以(yi)壓(ya)(ya)力*體(ti)積/時(shi)間(jian)表(biao)示(shi)(shi),即Pa.m3/s或Pa.m3/h。通常,泵(beng)(beng)(beng)會(hui)給出流(liu)(liu)(liu)(liu)量(liang)與入口(kou)壓(ya)(ya)力的(de)(de)(de)關(guan)系圖。 3.抽(chou)(chou)速(su)(su)(su)(su)(su)。在(zai)(zai)真(zhen)空(kong)泵(beng)(beng)(beng)的(de)(de)(de)吸(xi)(xi)入口(kou),每(mei)單(dan)位(wei)時(shi)間(jian)流(liu)(liu)(liu)(liu)動的(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)量(liang)稱為泵(beng)(beng)(beng)的(de)(de)(de)抽(chou)(chou)氣(qi)(qi)(qi)(qi)(qi)速(su)(su)(su)(su)(su)率(lv)。即,通過(guo)將流(liu)(liu)(liu)(liu)量(liang)QA(Pa.m3/s)除以(yi)測(ce)試罩(zhao)中的(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)A的(de)(de)(de)分壓(ya)(ya)pA而(er)獲(huo)得氣(qi)(qi)(qi)(qi)(qi)體(ti)A的(de)(de)(de)泵(beng)(beng)(beng)送速(su)(su)(su)(su)(su)度sA(m3/s)。典型的(de)(de)(de)真(zhen)空(kong)泵(beng)(beng)(beng)的(de)(de)(de)抽(chou)(chou)氣(qi)(qi)(qi)(qi)(qi)速(su)(su)(su)(su)(su)率(lv)與氣(qi)(qi)(qi)(qi)(qi)體(ti)類型有(you)(you)關(guan)。給定(ding)(ding)的(de)(de)(de)抽(chou)(chou)氣(qi)(qi)(qi)(qi)(qi)速(su)(su)(su)(su)(su)率(lv)表(biao)示(shi)(shi)某種(zhong)氣(qi)(qi)(qi)(qi)(qi)體(ti)的(de)(de)(de)抽(chou)(chou)氣(qi)(qi)(qi)(qi)(qi)速(su)(su)(su)(su)(su)率(lv)。如(ru)果沒有(you)(you)特殊指(zhi)示(shi)(shi),則(ze)使(shi)用(yong)多指(zhi)抽(chou)(chou)吸(xi)(xi)。 正確控制螺(luo)桿(gan)真(zhen)空(kong)泵(beng)(beng)(beng)流(liu)(liu)(liu)(liu)量(liang)不(bu)僅可(ke)以(yi)為設備提(ti)供良(liang)好(hao)的(de)(de)(de)保(bao)護,還可(ke)以(yi)提(ti)高使(shi)用(yong)率(lv)。那么(me)(me),該怎么(me)(me)做呢? 1,速(su)(su)(su)(su)(su)度控制 葉輪(lun)速(su)(su)(su)(su)(su)度的(de)(de)(de)變(bian)化會(hui)改變(bian)螺(luo)桿(gan)真(zhen)空(kong)泵(beng)(beng)(beng)的(de)(de)(de)流(liu)(liu)(liu)(liu)量(liang)曲(qu)(qu)線(xian),并且曲(qu)(qu)線(xian)的(de)(de)(de)特性(xing)(xing)不(bu)會(hui)改變(bian)。隨著速(su)(su)(su)(su)(su)度降低,曲(qu)(qu)線(xian)變(bian)平,揚程和(he)流(liu)(liu)(liu)(liu)速(su)(su)(su)(su)(su)降低。 2,旁通閥調整 使(shi)用(yong)與泵(beng)(beng)(beng)并聯的(de)(de)(de)中間(jian)閥。實際效果就(jiu)...

離(li)心泵有(you)很多(duo)不(bu)(bu)同(tong)的(de)(de)類型(xing),對(dui)于不(bu)(bu)同(tong)液體需要選(xuan)(xuan)擇(ze)不(bu)(bu)同(tong)的(de)(de)離(li)心泵,液體粘(zhan)度不(bu)(bu)大、流量(liang)較大、揚(yang)(yang)程不(bu)(bu)高時(shi),宜選(xuan)(xuan)用(yong)往復泵;液體粘(zhan)度較大、流量(liang)較小(xiao)、揚(yang)(yang)程不(bu)(bu)高或含有(you)氣(qi)(qi)泡時(shi),可選(xuan)(xuan)用(yong)旋(xuan)渦泵;液體粘(zhan)度較大、流量(liang)較小(xiao)、揚(yang)(yang)程較高時(shi),宜選(xuan)(xuan)用(yong)轉子泵。 理解(jie)類型(xing)的(de)(de)選(xuan)(xuan)擇(ze)是(shi)最基本的(de)(de),只有(you)正(zheng)確選(xuan)(xuan)擇(ze)才能使得正(zheng)常運轉,但是(shi)我們在(zai)使用(yong)中經常會(hui)遇到突(tu)然(ran)泄(xie)漏(lou)的(de)(de)問(wen)題,這又是(shi)哪些原因造成的(de)(de)呢(ni)?下面就來分析一下。 1、抽空、氣(qi)(qi)蝕或較長(chang)時(shi)間憋(bie)壓,導致密(mi)(mi)封破(po)壞; 2、對(dui)泵實(shi)際(ji)輸(shu)出量(liang)偏(pian)小(xiao),大量(liang)介(jie)質(zhi)泵內循環,熱量(liang)積聚,引起介(jie)質(zhi)氣(qi)(qi)化,導致密(mi)(mi)封失(shi)效; 3、回(hui)流量(liang)偏(pian)大,導致吸人管(guan)側容器(塔(ta)、釜、罐、池)底部沉渣(zha)泛(fan)起,損壞密(mi)(mi)封; 4、對(dui)較長(chang)時(shi)間停(ting)運,重新起動(dong)(dong)時(shi)沒(mei)有(you)手動(dong)(dong)盤(pan)車,摩擦(ca)副因粘(zhan)連而扯壞密(mi)(mi)封面; 5、介(jie)質(zhi)中腐蝕性(xing)、聚合性(xing)、結膠(jiao)性(xing)物質(zhi)增(zeng)多(duo); 6、環境溫度急劇變化; 7、工況頻繁變化或調整; 8、突(tu)然(ran)停(ting)電或故障停(ting)機(ji)等。 當(dang)遇到突(tu)然(ran)泄(xie)漏(lou)的(de)(de)問(wen)題,我們一定要正(zheng)確分析,以(yi)采取(qu)對(dui)的(de)(de)措施,以(yi)免造成不(bu)(bu)要的(de)(de)損失(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,則可以卸下水環真空泵過濾器。 5.更換水環真空泵口環,調整軸向?
