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)閥作為自吸泵的組成部分之一裝在吸(xi)(xi)液(ye)(ye)(ye)口的(de)(de)(de)進氣管(guan)(guan)上(shang)，啟泵(beng)時(shi)(shi)(shi)電(dian)控閥密(mi)閉泵(beng)體吸(xi)(xi)液(ye)(ye)(ye)管(guan)(guan)上(shang)的(de)(de)(de)進氣口，使(shi)自吸(xi)(xi)泵(beng)泵(beng)腔內(nei)(nei)形成真(zhen)空(kong)，完成自吸(xi)(xi)全(quan)過(guo)程。停泵(beng)時(shi)(shi)(shi)電(dian)控閥開啟，空(kong)氣從密(mi)閉口進入(ru)，水泵(beng)液(ye)(ye)(ye)管(guan)(guan)內(nei)(nei)迅速隔離吸(xi)(xi)液(ye)(ye)(ye)管(guan)(guan)內(nei)(nei)共流(liu)的(de)(de)(de)介(jie)(jie)質(zhi)，確保(bao)泵(beng)腔的(de)(de)(de)介(jie)(jie)質(zhi)不隨吸(xi)(xi)液(ye)(ye)(ye)管(guan)(guan)腔內(nei)(nei)的(de)(de)(de)介(jie)(jie)質(zhi)回(hui)落到吸(xi)(xi)液(ye)(ye)(ye)池中，以達(da)到消(xiao)除虹吸(xi)(xi)的(de)(de)(de)目的(de)(de)(de)，確保(bao)自吸(xi)(xi)泵(beng)二次自吸(xi)(xi)時(shi)(shi)(shi)正常自吸(xi)(xi)及運(yun)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)機啟動(dong)(dong)時，電(dian)(dian)(dian)磁閥同(tong)時同(tong)步通(tong)電(dian)(dian)(dian)啟動(dong)(dong)，電(dian)(dian)(dian)磁鐵芯(xin)吸(xi)(xi)合銜鐵時帶(dai)動(dong)(dong)彈(dan)性(xing)架(jia)下移(yi)，驅動(dong)(dong)閥芯(xin)活(huo)塞桿向活(huo)塞缸體底(di)部密(mi)封墊(dian)壓緊，實(shi)現(xian)密(mi)封，關(guan)閉吸(xi)(xi)液管上進(jin)氣口通(tong)氣孔(kong)，使自(zi)吸(xi)(xi)泵(beng)開始自(zi)吸(xi)(xi)并進(jin)入(ru)(ru)正常運行狀態。當停(ting)電(dian)(dian)(dian)使電(dian)(dian)(dian)機斷電(dian)(dian)(dian)，電(dian)(dian)(dian)磁閥電(dian)(dian)(dian)磁線圈同(tong)時斷電(dian)(dian)(dian)，電(dian)(dian)(dian)磁鐵芯(xin)的(de)(de)磁力(li)消(xiao)失，彈(dan)性(xing)架(jia)受壓縮彈(dan)簧反作用上移(yi)復位，帶(dai)動(dong)(dong)閥芯(xin)桿活(huo)塞離(li)開活(huo)塞缸底(di)，開啟通(tong)氣孔(kong)。使空氣進(jin)入(ru)(ru)吸(xi)(xi)液管腔，使泵(beng)腔內(nei)的(de)(de)介(jie)質(zhi)與吸(xi)(xi)液管內(nei)的(de)(de)介(jie)質(zhi)隔離(li)，消(xiao)除(chu)虹吸(xi)(xi)，確保(bao)自(zi)吸(xi)(xi)泵(beng)泵(beng)腔介(jie)質(zhi)貯量，以(yi)供下次(ci)啟泵(beng)時自(zi)吸(xi)(xi)及(ji)正常運行。
三、自控式自吸泵怎么調
1、先(xian)打開控制器罩，然后平口螺絲刀把(ba)中間的(de)(de)調節(jie)旋(xuan)(xuan)鈕順(shun)時針向上旋(xuan)(xuan)，以(yi)獲得更高的(de)(de)斷開壓力；
2、把壓力罐上面的(de)加氣(qi)螺(luo)母擰開，用打氣(qi)筒給里面加入(ru)氣(qi)體，使其氣(qi)壓罐能起到穩壓的(de)作用。
