眾所周知，對于各種(zhong)真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)性(xing)能，都(dou)有(you)規定(ding)的(de)(de)(de)(de)(de)(de)測(ce)試方法來(lai)測(ce)試該性(xing)能的(de)(de)(de)(de)(de)(de)性(xing)能，主要性(xing)能是極限壓(ya)力(li)(li)，流量(liang)和(he)抽速(su)(su)(su)。這次(ci)，小編打算討論(lun)螺(luo)桿真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)流量(liang)，例如如何控制(zhi)其流量(liang)，流量(liang)不(bu)(bu)足的(de)(de)(de)(de)(de)(de)原因以及如何消除(chu)此問題。相信(xin)許多用(yong)戶對這些問題感到(dao)困惑，不(bu)(bu)用(yong)擔心，請跟隨螺(luo)桿真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)廠(chang)家進行了解。 首先，讓我(wo)們(men)簡單(dan)介紹一(yi)下真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)主要性(xing)能的(de)(de)(de)(de)(de)(de)概(gai)念。 1.極限壓(ya)力(li)(li)。真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)與(yu)檢測(ce)容(rong)器相連，放置待測(ce)氣(qi)(qi)(qi)體(ti)(ti)后，連續長時間(jian)(jian)抽氣(qi)(qi)(qi)。當容(rong)器的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)壓(ya)不(bu)(bu)再(zai)降(jiang)低并(bing)且壓(ya)力(li)(li)保(bao)持(chi)在(zai)一(yi)定(ding)值時，次(ci)級壓(ya)力(li)(li)就(jiu)(jiu)是泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)極限壓(ya)力(li)(li)。 2.流量(liang)。在(zai)真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)吸(xi)入口，每單(dan)位(wei)時間(jian)(jian)的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)流量(liang)稱(cheng)為泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)流量(liang)。在(zai)真(zhen)(zhen)(zhen)空(kong)(kong)技術中(zhong)(zhong)(zhong)，流量(liang)單(dan)位(wei)以壓(ya)力(li)(li)*體(ti)(ti)積(ji)/時間(jian)(jian)表(biao)示，即(ji)Pa.m3/s或Pa.m3/h。通常，泵(beng)(beng)(beng)會給出流量(liang)與(yu)入口壓(ya)力(li)(li)的(de)(de)(de)(de)(de)(de)關(guan)系圖。 3.抽速(su)(su)(su)。在(zai)真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)吸(xi)入口，每單(dan)位(wei)時間(jian)(jian)流動的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)量(liang)稱(cheng)為泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)抽氣(qi)(qi)(qi)速(su)(su)(su)率。即(ji)，通過將(jiang)流量(liang)QA(Pa.m3/s)除(chu)以測(ce)試罩中(zhong)(zhong)(zhong)的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)A的(de)(de)(de)(de)(de)(de)分壓(ya)pA而獲得氣(qi)(qi)(qi)體(ti)(ti)A的(de)(de)(de)(de)(de)(de)泵(beng)(beng)(beng)送速(su)(su)(su)度sA(m3/s)。典(dian)型的(de)(de)(de)(de)(de)(de)真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)抽氣(qi)(qi)(qi)速(su)(su)(su)率與(yu)氣(qi)(qi)(qi)體(ti)(ti)類(lei)型有(you)關(guan)。給定(ding)的(de)(de)(de)(de)(de)(de)抽氣(qi)(qi)(qi)速(su)(su)(su)率表(biao)示某(mou)種(zhong)氣(qi)(qi)(qi)體(ti)(ti)的(de)(de)(de)(de)(de)(de)抽氣(qi)(qi)(qi)速(su)(su)(su)率。如果(guo)(guo)沒有(you)特(te)殊指示，則(ze)使用(yong)多指抽吸(xi)。 正(zheng)確控制(zhi)螺(luo)桿真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)流量(liang)不(bu)(bu)僅(jin)可以為設備提(ti)供(gong)良好的(de)(de)(de)(de)(de)(de)保(bao)護，還可以提(ti)高使用(yong)率。那么，該怎么做呢? 1，速(su)(su)(su)度控制(zhi) 葉(xie)輪速(su)(su)(su)度的(de)(de)(de)(de)(de)(de)變(bian)化會改(gai)變(bian)螺(luo)桿真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)流量(liang)曲(qu)(qu)線(xian)，并(bing)且曲(qu)(qu)線(xian)的(de)(de)(de)(de)(de)(de)特(te)性(xing)不(bu)(bu)會改(gai)變(bian)。隨著速(su)(su)(su)度降(jiang)低，曲(qu)(qu)線(xian)變(bian)平(ping)，揚程和(he)流速(su)(su)(su)降(jiang)低。 2，旁通閥調整 使用(yong)與(yu)泵(beng)(beng)(beng)并(bing)聯的(de)(de)(de)(de)(de)(de)中(zhong)(zhong)(zhong)間(jian)(jian)閥。實際效果(guo)(guo)就(jiu)(jiu)...
