眾所(suo)周知,對于各種(zhong)真(zhen)空(kong)泵(beng)的(de)性(xing)(xing)能(neng),都有規定(ding)的(de)測(ce)試方法來測(ce)試該性(xing)(xing)能(neng)的(de)性(xing)(xing)能(neng),主(zhu)要性(xing)(xing)能(neng)是極限壓(ya)力(li)(li)(li),流(liu)量(liang)(liang)(liang)和(he)抽速(su)(su)。這次,小編打算(suan)討論螺桿(gan)(gan)真(zhen)空(kong)泵(beng)的(de)流(liu)量(liang)(liang)(liang),例如如何(he)控制其流(liu)量(liang)(liang)(liang),流(liu)量(liang)(liang)(liang)不足的(de)原因以(yi)及如何(he)消(xiao)除此問(wen)題(ti)。相信許多用(yong)(yong)戶(hu)對這些(xie)問(wen)題(ti)感到困惑,不用(yong)(yong)擔心(xin),請跟(gen)隨(sui)螺桿(gan)(gan)真(zhen)空(kong)泵(beng)廠家進行(xing)了(le)解。  首先,讓我(wo)們簡單(dan)(dan)介紹一下真(zhen)空(kong)泵(beng)主(zhu)要性(xing)(xing)能(neng)的(de)概念。  1.極限壓(ya)力(li)(li)(li)。真(zhen)空(kong)泵(beng)與檢測(ce)容(rong)器(qi)相連,放(fang)置待測(ce)氣(qi)(qi)(qi)體后,連續(xu)長時間(jian)(jian)(jian)抽氣(qi)(qi)(qi)。當(dang)容(rong)器(qi)的(de)氣(qi)(qi)(qi)壓(ya)不再降低并且壓(ya)力(li)(li)(li)保持在(zai)(zai)一定(ding)值(zhi)時,次級壓(ya)力(li)(li)(li)就(jiu)是泵(beng)的(de)極限壓(ya)力(li)(li)(li)。  2.流(liu)量(liang)(liang)(liang)。在(zai)(zai)真(zhen)空(kong)泵(beng)的(de)吸入(ru)(ru)口(kou)(kou),每單(dan)(dan)位時間(jian)(jian)(jian)的(de)氣(qi)(qi)(qi)體流(liu)量(liang)(liang)(liang)稱為(wei)泵(beng)的(de)流(liu)量(liang)(liang)(liang)。在(zai)(zai)真(zhen)空(kong)技術中(zhong),流(liu)量(liang)(liang)(liang)單(dan)(dan)位以(yi)壓(ya)力(li)(li)(li)*體積/時間(jian)(jian)(jian)表示(shi),即Pa.m3/s或Pa.m3/h。通常,泵(beng)會(hui)給出(chu)流(liu)量(liang)(liang)(liang)與入(ru)(ru)口(kou)(kou)壓(ya)力(li)(li)(li)的(de)關系圖(tu)。  3.抽速(su)(su)。在(zai)(zai)真(zhen)空(kong)泵(beng)的(de)吸入(ru)(ru)口(kou)(kou),每單(dan)(dan)位時間(jian)(jian)(jian)流(liu)動的(de)氣(qi)(qi)(qi)體量(liang)(liang)(liang)稱為(wei)泵(beng)的(de)抽氣(qi)(qi)(qi)速(su)(su)率(lv)。即,通過將流(liu)量(liang)(liang)(liang)QA(Pa.m3/s)除以(yi)測(ce)試罩中(zhong)的(de)氣(qi)(qi)(qi)體A的(de)分壓(ya)pA而獲得氣(qi)(qi)(qi)體A的(de)泵(beng)送速(su)(su)度(du)sA(m3/s)。典(dian)型的(de)真(zhen)空(kong)泵(beng)的(de)抽氣(qi)(qi)(qi)速(su)(su)率(lv)與氣(qi)(qi)(qi)體類型有關。給定(ding)的(de)抽氣(qi)(qi)(qi)速(su)(su)率(lv)表示(shi)某(mou)種(zhong)氣(qi)(qi)(qi)體的(de)抽氣(qi)(qi)(qi)速(su)(su)率(lv)。如果沒有特殊指示(shi),則使用(yong)(yong)多指抽吸。  正確控制螺桿(gan)(gan)真(zhen)空(kong)泵(beng)流(liu)量(liang)(liang)(liang)不僅可(ke)以(yi)為(wei)設(she)備提供良(liang)好的(de)保護(hu),還可(ke)以(yi)提高使用(yong)(yong)率(lv)。那么(me),該怎么(me)做呢(ni)?  1,速(su)(su)度(du)控制  葉輪速(su)(su)度(du)的(de)變(bian)化會(hui)改變(bian)螺桿(gan)(gan)真(zhen)空(kong)泵(beng)的(de)流(liu)量(liang)(liang)(liang)曲(qu)線,并且曲(qu)線的(de)特性(xing)(xing)不會(hui)改變(bian)。隨(sui)著(zhu)速(su)(su)度(du)降低,曲(qu)線變(bian)平,揚程和(he)流(liu)速(su)(su)降低。  2,旁通閥調整  使用(yong)(yong)與泵(beng)并聯的(de)中(zhong)間(jian)(jian)(jian)閥。實(shi)際效果就(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
