眾所(suo)周知,對于各(ge)種真(zhen)空(kong)(kong)泵(beng)(beng)的(de)(de)(de)性能(neng)(neng),都有規定的(de)(de)(de)測(ce)(ce)試(shi)方(fang)法來測(ce)(ce)試(shi)該(gai)性能(neng)(neng)的(de)(de)(de)性能(neng)(neng),主要性能(neng)(neng)是極限(xian)壓(ya)力(li)(li),流(liu)(liu)(liu)量(liang)(liang)和抽速(su)(su)。這次,小編打(da)算討論螺(luo)桿(gan)真(zhen)空(kong)(kong)泵(beng)(beng)的(de)(de)(de)流(liu)(liu)(liu)量(liang)(liang),例如如何控(kong)制(zhi)其流(liu)(liu)(liu)量(liang)(liang),流(liu)(liu)(liu)量(liang)(liang)不(bu)(bu)足的(de)(de)(de)原因以及如何消除(chu)此問(wen)(wen)題。相(xiang)信許多(duo)(duo)用戶對這些(xie)問(wen)(wen)題感到困惑,不(bu)(bu)用擔心(xin),請跟(gen)隨螺(luo)桿(gan)真(zhen)空(kong)(kong)泵(beng)(beng)廠家(jia)進行了(le)解。 首先,讓我們簡單介紹一下真(zhen)空(kong)(kong)泵(beng)(beng)主要性能(neng)(neng)的(de)(de)(de)概(gai)念(nian)。 1.極限(xian)壓(ya)力(li)(li)。真(zhen)空(kong)(kong)泵(beng)(beng)與(yu)檢(jian)測(ce)(ce)容(rong)器(qi)相(xiang)連(lian),放置待測(ce)(ce)氣(qi)(qi)(qi)體(ti)后,連(lian)續長時(shi)間(jian)(jian)抽氣(qi)(qi)(qi)。當容(rong)器(qi)的(de)(de)(de)氣(qi)(qi)(qi)壓(ya)不(bu)(bu)再降低并(bing)(bing)且(qie)壓(ya)力(li)(li)保持在(zai)(zai)一定值時(shi),次級(ji)壓(ya)力(li)(li)就(jiu)(jiu)是泵(beng)(beng)的(de)(de)(de)極限(xian)壓(ya)力(li)(li)。 2.流(liu)(liu)(liu)量(liang)(liang)。在(zai)(zai)真(zhen)空(kong)(kong)泵(beng)(beng)的(de)(de)(de)吸入(ru)口,每(mei)單位時(shi)間(jian)(jian)的(de)(de)(de)氣(qi)(qi)(qi)體(ti)流(liu)(liu)(liu)量(liang)(liang)稱為泵(beng)(beng)的(de)(de)(de)流(liu)(liu)(liu)量(liang)(liang)。在(zai)(zai)真(zhen)空(kong)(kong)技術(shu)中(zhong),流(liu)(liu)(liu)量(liang)(liang)單位以壓(ya)力(li)(li)*體(ti)積/時(shi)間(jian)(jian)表(biao)示,即Pa.m3/s或Pa.m3/h。通常,泵(beng)(beng)會(hui)給出流(liu)(liu)(liu)量(liang)(liang)與(yu)入(ru)口壓(ya)力(li)(li)的(de)(de)(de)關(guan)系圖。 3.抽速(su)(su)。在(zai)(zai)真(zhen)空(kong)(kong)泵(beng)(beng)的(de)(de)(de)吸入(ru)口,每(mei)單位時(shi)間(jian)(jian)流(liu)(liu)(liu)動的(de)(de)(de)氣(qi)(qi)(qi)體(ti)量(liang)(liang)稱為泵(beng)(beng)的(de)(de)(de)抽氣(qi)(qi)(qi)速(su)(su)率(lv)(lv)。即,通過將流(liu)(liu)(liu)量(liang)(liang)QA(Pa.m3/s)除(chu)以測(ce)(ce)試(shi)罩中(zhong)的(de)(de)(de)氣(qi)(qi)(qi)體(ti)A的(de)(de)(de)分壓(ya)pA而獲得氣(qi)(qi)(qi)體(ti)A的(de)(de)(de)泵(beng)(beng)送速(su)(su)度sA(m3/s)。典(dian)型(xing)的(de)(de)(de)真(zhen)空(kong)(kong)泵(beng)(beng)的(de)(de)(de)抽氣(qi)(qi)(qi)速(su)(su)率(lv)(lv)與(yu)氣(qi)(qi)(qi)體(ti)類(lei)型(xing)有關(guan)。給定的(de)(de)(de)抽氣(qi)(qi)(qi)速(su)(su)率(lv)(lv)表(biao)示某種氣(qi)(qi)(qi)體(ti)的(de)(de)(de)抽氣(qi)(qi)(qi)速(su)(su)率(lv)(lv)。如果沒有特殊指示,則(ze)使(shi)用多(duo)(duo)指抽吸。 正確控(kong)制(zhi)螺(luo)桿(gan)真(zhen)空(kong)(kong)泵(beng)(beng)流(liu)(liu)(liu)量(liang)(liang)不(bu)(bu)僅可以為設備提供良好的(de)(de)(de)保護(hu),還可以提高使(shi)用率(lv)(lv)。那么,該(gai)怎么做呢? 1,速(su)(su)度控(kong)制(zhi) 葉輪(lun)速(su)(su)度的(de)(de)(de)變(bian)化會(hui)改變(bian)螺(luo)桿(gan)真(zhen)空(kong)(kong)泵(beng)(beng)的(de)(de)(de)流(liu)(liu)(liu)量(liang)(liang)曲線(xian),并(bing)(bing)且(qie)曲線(xian)的(de)(de)(de)特性不(bu)(bu)會(hui)改變(bian)。隨著速(su)(su)度降低,曲線(xian)變(bian)平(ping),揚程和流(liu)(liu)(liu)速(su)(su)降低。 2,旁通閥調整 使(shi)用與(yu)泵(beng)(beng)并(bing)(bing)聯的(de)(de)(de)中(zhong)間(jian)(jian)閥。實際效果就(jiu)(jiu)...

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?
