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(dian)動閥作(zuo)為自吸泵(beng)的組成(cheng)(cheng)部分之一裝在吸(xi)(xi)液(ye)口的(de)(de)進(jin)氣管(guan)上，啟(qi)泵(beng)(beng)時電(dian)(dian)控(kong)(kong)閥密(mi)閉泵(beng)(beng)體吸(xi)(xi)液(ye)管(guan)上的(de)(de)進(jin)氣口，使自(zi)(zi)吸(xi)(xi)泵(beng)(beng)泵(beng)(beng)腔(qiang)內(nei)(nei)形成(cheng)(cheng)真空，完成(cheng)(cheng)自(zi)(zi)吸(xi)(xi)全過(guo)程。停泵(beng)(beng)時電(dian)(dian)控(kong)(kong)閥開(kai)啟(qi)，空氣從密(mi)閉口進(jin)入，水泵(beng)(beng)液(ye)管(guan)內(nei)(nei)迅速隔(ge)離吸(xi)(xi)液(ye)管(guan)內(nei)(nei)共流的(de)(de)介質(zhi)，確保泵(beng)(beng)腔(qiang)的(de)(de)介質(zhi)不隨(sui)吸(xi)(xi)液(ye)管(guan)腔(qiang)內(nei)(nei)的(de)(de)介質(zhi)回落到吸(xi)(xi)液(ye)池中，以達到消(xiao)除虹(hong)吸(xi)(xi)的(de)(de)目的(de)(de)，確保自(zi)(zi)吸(xi)(xi)泵(beng)(beng)二次自(zi)(zi)吸(xi)(xi)時正常自(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)機(ji)啟動(dong)(dong)(dong)時(shi)(shi)，電(dian)(dian)磁閥(fa)同時(shi)(shi)同步通電(dian)(dian)啟動(dong)(dong)(dong)，電(dian)(dian)磁鐵(tie)芯(xin)吸(xi)(xi)合銜鐵(tie)時(shi)(shi)帶動(dong)(dong)(dong)彈(dan)(dan)性架下(xia)移，驅動(dong)(dong)(dong)閥(fa)芯(xin)活塞桿(gan)向(xiang)活塞缸(gang)體底部密封墊壓(ya)緊，實(shi)現密封，關閉吸(xi)(xi)液管(guan)上進(jin)氣(qi)(qi)口通氣(qi)(qi)孔(kong)，使自(zi)(zi)吸(xi)(xi)泵(beng)開始自(zi)(zi)吸(xi)(xi)并(bing)進(jin)入正(zheng)常(chang)運(yun)行狀態。當停電(dian)(dian)使電(dian)(dian)機(ji)斷電(dian)(dian)，電(dian)(dian)磁閥(fa)電(dian)(dian)磁線(xian)圈同時(shi)(shi)斷電(dian)(dian)，電(dian)(dian)磁鐵(tie)芯(xin)的(de)磁力消(xiao)失，彈(dan)(dan)性架受壓(ya)縮彈(dan)(dan)簧(huang)反作(zuo)用上移復位，帶動(dong)(dong)(dong)閥(fa)芯(xin)桿(gan)活塞離開活塞缸(gang)底，開啟通氣(qi)(qi)孔(kong)。使空(kong)氣(qi)(qi)進(jin)入吸(xi)(xi)液管(guan)腔，使泵(beng)腔內(nei)(nei)的(de)介(jie)質與(yu)吸(xi)(xi)液管(guan)內(nei)(nei)的(de)介(jie)質隔離，消(xiao)除(chu)虹吸(xi)(xi)，確保(bao)自(zi)(zi)吸(xi)(xi)泵(beng)泵(beng)腔介(jie)質貯(zhu)量，以供下(xia)次啟泵(beng)時(shi)(shi)自(zi)(zi)吸(xi)(xi)及正(zheng)常(chang)運(yun)行。
三、自控式自吸泵怎么調
1、先打(da)開(kai)控制器罩，然后平口螺絲(si)刀把中(zhong)間的調節旋鈕順時針(zhen)向上旋，以獲得更高的斷開(kai)壓(ya)力(li)；
2、把壓力罐上面的加氣(qi)(qi)螺(luo)母擰開，用打氣(qi)(qi)筒給(gei)里(li)面加入氣(qi)(qi)體(ti)，使其氣(qi)(qi)壓罐能起(qi)到穩壓的作用。
