眾所周知,對(dui)于各種真(zhen)空(kong)(kong)泵(beng)(beng)的(de)(de)性(xing)(xing)能(neng),都(dou)有規定(ding)(ding)的(de)(de)測試方(fang)法來(lai)測試該性(xing)(xing)能(neng)的(de)(de)性(xing)(xing)能(neng),主要性(xing)(xing)能(neng)是(shi)極(ji)限(xian)壓(ya)(ya)力(li)(li),流(liu)(liu)(liu)(liu)量和抽速。這次,小編打算討論螺(luo)(luo)(luo)桿真(zhen)空(kong)(kong)泵(beng)(beng)的(de)(de)流(liu)(liu)(liu)(liu)量,例如如何控制(zhi)其流(liu)(liu)(liu)(liu)量,流(liu)(liu)(liu)(liu)量不(bu)(bu)(bu)足的(de)(de)原因以及如何消除此(ci)問(wen)題(ti)。相信許(xu)多用(yong)戶對(dui)這些(xie)問(wen)題(ti)感(gan)到困惑,不(bu)(bu)(bu)用(yong)擔心,請跟隨螺(luo)(luo)(luo)桿真(zhen)空(kong)(kong)泵(beng)(beng)廠家進行了(le)解。  首(shou)先,讓(rang)我們簡單(dan)(dan)(dan)介紹(shao)一(yi)下(xia)真(zhen)空(kong)(kong)泵(beng)(beng)主要性(xing)(xing)能(neng)的(de)(de)概念(nian)。  1.極(ji)限(xian)壓(ya)(ya)力(li)(li)。真(zhen)空(kong)(kong)泵(beng)(beng)與(yu)檢測容器(qi)(qi)相連(lian),放置待測氣(qi)(qi)(qi)(qi)體(ti)后,連(lian)續長時(shi)間抽氣(qi)(qi)(qi)(qi)。當容器(qi)(qi)的(de)(de)氣(qi)(qi)(qi)(qi)壓(ya)(ya)不(bu)(bu)(bu)再降低并且壓(ya)(ya)力(li)(li)保持在(zai)一(yi)定(ding)(ding)值時(shi),次級壓(ya)(ya)力(li)(li)就(jiu)是(shi)泵(beng)(beng)的(de)(de)極(ji)限(xian)壓(ya)(ya)力(li)(li)。  2.流(liu)(liu)(liu)(liu)量。在(zai)真(zhen)空(kong)(kong)泵(beng)(beng)的(de)(de)吸入口(kou)(kou),每單(dan)(dan)(dan)位(wei)時(shi)間的(de)(de)氣(qi)(qi)(qi)(qi)體(ti)流(liu)(liu)(liu)(liu)量稱為(wei)泵(beng)(beng)的(de)(de)流(liu)(liu)(liu)(liu)量。在(zai)真(zhen)空(kong)(kong)技術(shu)中,流(liu)(liu)(liu)(liu)量單(dan)(dan)(dan)位(wei)以壓(ya)(ya)力(li)(li)*體(ti)積/時(shi)間表示(shi),即(ji)Pa.m3/s或Pa.m3/h。通常(chang),泵(beng)(beng)會給出流(liu)(liu)(liu)(liu)量與(yu)入口(kou)(kou)壓(ya)(ya)力(li)(li)的(de)(de)關(guan)(guan)系圖。  3.抽速。在(zai)真(zhen)空(kong)(kong)泵(beng)(beng)的(de)(de)吸入口(kou)(kou),每單(dan)(dan)(dan)位(wei)時(shi)間流(liu)(liu)(liu)(liu)動(dong)的(de)(de)氣(qi)(qi)(qi)(qi)體(ti)量稱為(wei)泵(beng)(beng)的(de)(de)抽氣(qi)(qi)(qi)(qi)速率(lv)。即(ji),通過將流(liu)(liu)(liu)(liu)量QA(Pa.m3/s)除以測試罩中的(de)(de)氣(qi)(qi)(qi)(qi)體(ti)A的(de)(de)分壓(ya)(ya)pA而獲得氣(qi)(qi)(qi)(qi)體(ti)A的(de)(de)泵(beng)(beng)送速度sA(m3/s)。典型(xing)的(de)(de)真(zhen)空(kong)(kong)泵(beng)(beng)的(de)(de)抽氣(qi)(qi)(qi)(qi)速率(lv)與(yu)氣(qi)(qi)(qi)(qi)體(ti)類型(xing)有關(guan)(guan)。給定(ding)(ding)的(de)(de)抽氣(qi)(qi)(qi)(qi)速率(lv)表示(shi)某種氣(qi)(qi)(qi)(qi)體(ti)的(de)(de)抽氣(qi)(qi)(qi)(qi)速率(lv)。如果沒有特殊(shu)指示(shi),則使(shi)(shi)用(yong)多指抽吸。  正確(que)控制(zhi)螺(luo)(luo)(luo)桿真(zhen)空(kong)(kong)泵(beng)(beng)流(liu)(liu)(liu)(liu)量不(bu)(bu)(bu)僅可以為(wei)設備提(ti)供良好的(de)(de)保護,還可以提(ti)高(gao)使(shi)(shi)用(yong)率(lv)。那么(me)(me),該怎么(me)(me)做呢?  1,速度控制(zhi)  葉(xie)輪速度的(de)(de)變(bian)(bian)化會改變(bian)(bian)螺(luo)(luo)(luo)桿真(zhen)空(kong)(kong)泵(beng)(beng)的(de)(de)流(liu)(liu)(liu)(liu)量曲(qu)線(xian),并且曲(qu)線(xian)的(de)(de)特性(xing)(xing)不(bu)(bu)(bu)會改變(bian)(bian)。隨著速度降低,曲(qu)線(xian)變(bian)(bian)平,揚程和流(liu)(liu)(liu)(liu)速降低。  2,旁通閥調(diao)整  使(shi)(shi)用(yong)與(yu)泵(beng)(beng)并聯的(de)(de)中間閥。實際效果就(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。
