一、自控自吸泵電磁閥作用是什么
電動空氣電磁閥是為WFB系列無密封自控自吸泵或其它型號無密封自吸泵設計的，是自吸泵的重要組成部分之一。電動(dong)閥作為自吸(xi)泵的組(zu)成部分之一裝在(zai)吸(xi)(xi)液口的(de)進氣管上(shang)，啟泵(beng)(beng)時(shi)電控閥密閉(bi)泵(beng)(beng)體(ti)吸(xi)(xi)液管上(shang)的(de)進氣口，使自(zi)(zi)(zi)吸(xi)(xi)泵(beng)(beng)泵(beng)(beng)腔內形成真空，完成自(zi)(zi)(zi)吸(xi)(xi)全過程。停(ting)泵(beng)(beng)時(shi)電控閥開啟，空氣從密閉(bi)口進入，水泵(beng)(beng)液管內迅速隔(ge)離吸(xi)(xi)液管內共流的(de)介(jie)質(zhi)，確(que)保(bao)泵(beng)(beng)腔的(de)介(jie)質(zhi)不隨吸(xi)(xi)液管腔內的(de)介(jie)質(zhi)回落(luo)到吸(xi)(xi)液池中，以達到消除虹吸(xi)(xi)的(de)目的(de)，確(que)保(bao)自(zi)(zi)(zi)吸(xi)(xi)泵(beng)(beng)二次自(zi)(zi)(zi)吸(xi)(xi)時(shi)正(zheng)常(chang)自(zi)(zi)(zi)吸(xi)(xi)及運行。
二、自控式自吸泵電磁閥工作原理
電磁閥接線與水泵電機電源并聯（三相三線380V電源任意兩線，電壓為380V），自吸泵電(dian)(dian)(dian)機(ji)啟(qi)動(dong)(dong)(dong)(dong)時(shi)，電(dian)(dian)(dian)磁(ci)閥(fa)同(tong)時(shi)同(tong)步通(tong)電(dian)(dian)(dian)啟(qi)動(dong)(dong)(dong)(dong)，電(dian)(dian)(dian)磁(ci)鐵芯(xin)吸(xi)(xi)(xi)(xi)合銜鐵時(shi)帶動(dong)(dong)(dong)(dong)彈(dan)性架下移(yi)，驅(qu)動(dong)(dong)(dong)(dong)閥(fa)芯(xin)活塞桿(gan)向活塞缸體底部密封墊(dian)壓(ya)緊，實現(xian)密封，關(guan)閉(bi)吸(xi)(xi)(xi)(xi)液管(guan)(guan)上(shang)進(jin)氣(qi)口通(tong)氣(qi)孔，使(shi)自(zi)吸(xi)(xi)(xi)(xi)泵開始自(zi)吸(xi)(xi)(xi)(xi)并進(jin)入正常運行狀(zhuang)態。當停(ting)電(dian)(dian)(dian)使(shi)電(dian)(dian)(dian)機(ji)斷電(dian)(dian)(dian)，電(dian)(dian)(dian)磁(ci)閥(fa)電(dian)(dian)(dian)磁(ci)線(xian)圈同(tong)時(shi)斷電(dian)(dian)(dian)，電(dian)(dian)(dian)磁(ci)鐵芯(xin)的(de)磁(ci)力消(xiao)失，彈(dan)性架受壓(ya)縮彈(dan)簧反作(zuo)用上(shang)移(yi)復位(wei)，帶動(dong)(dong)(dong)(dong)閥(fa)芯(xin)桿(gan)活塞離(li)開活塞缸底，開啟(qi)通(tong)氣(qi)孔。使(shi)空氣(qi)進(jin)入吸(xi)(xi)(xi)(xi)液管(guan)(guan)腔(qiang)，使(shi)泵腔(qiang)內(nei)的(de)介質(zhi)與吸(xi)(xi)(xi)(xi)液管(guan)(guan)內(nei)的(de)介質(zhi)隔離(li)，消(xiao)除虹吸(xi)(xi)(xi)(xi)，確保(bao)自(zi)吸(xi)(xi)(xi)(xi)泵泵腔(qiang)介質(zhi)貯量，以供(gong)下次啟(qi)泵時(shi)自(zi)吸(xi)(xi)(xi)(xi)及(ji)正常運行。
三、自控式自吸泵怎么調
1、先打(da)開控制器罩，然后(hou)平口(kou)螺絲刀(dao)把中(zhong)間的調節旋(xuan)鈕(niu)順時針向上旋(xuan)，以獲得(de)更高的斷開壓力；
2、把壓力罐(guan)上(shang)面的加氣螺(luo)母(mu)擰(ning)開，用打(da)氣筒給里(li)面加入氣體(ti)，使其氣壓罐(guan)能起到穩壓的作用。
