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。電動閥作為(wei)自(zi)吸泵的組成(cheng)部(bu)分之一(yi)裝在吸(xi)(xi)液(ye)(ye)口的進(jin)(jin)氣管(guan)(guan)(guan)上(shang)，啟泵(beng)(beng)時電控閥密閉泵(beng)(beng)體吸(xi)(xi)液(ye)(ye)管(guan)(guan)(guan)上(shang)的進(jin)(jin)氣口，使自(zi)(zi)吸(xi)(xi)泵(beng)(beng)泵(beng)(beng)腔內(nei)(nei)形成(cheng)真空，完成(cheng)自(zi)(zi)吸(xi)(xi)全過(guo)程(cheng)。停泵(beng)(beng)時電控閥開啟，空氣從密閉口進(jin)(jin)入(ru)，水泵(beng)(beng)液(ye)(ye)管(guan)(guan)(guan)內(nei)(nei)迅速隔離吸(xi)(xi)液(ye)(ye)管(guan)(guan)(guan)內(nei)(nei)共流(liu)的介(jie)質，確保泵(beng)(beng)腔的介(jie)質不(bu)隨吸(xi)(xi)液(ye)(ye)管(guan)(guan)(guan)腔內(nei)(nei)的介(jie)質回落到(dao)(dao)吸(xi)(xi)液(ye)(ye)池中，以達(da)到(dao)(dao)消除(chu)虹吸(xi)(xi)的目的，確保自(zi)(zi)吸(xi)(xi)泵(beng)(beng)二次自(zi)(zi)吸(xi)(xi)時正(zheng)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)(dian)機啟(qi)動(dong)(dong)時(shi)(shi)(shi)，電(dian)(dian)(dian)磁(ci)(ci)閥同(tong)時(shi)(shi)(shi)同(tong)步通(tong)電(dian)(dian)(dian)啟(qi)動(dong)(dong)，電(dian)(dian)(dian)磁(ci)(ci)鐵(tie)芯吸(xi)(xi)合銜鐵(tie)時(shi)(shi)(shi)帶動(dong)(dong)彈性架(jia)(jia)下移(yi)(yi)，驅(qu)動(dong)(dong)閥芯活(huo)塞(sai)桿向活(huo)塞(sai)缸體(ti)底部密封(feng)墊壓緊，實現(xian)密封(feng)，關閉吸(xi)(xi)液管(guan)上進(jin)(jin)氣口(kou)通(tong)氣孔，使(shi)(shi)自(zi)吸(xi)(xi)泵開始(shi)自(zi)吸(xi)(xi)并進(jin)(jin)入正常運(yun)行狀態。當(dang)停電(dian)(dian)(dian)使(shi)(shi)電(dian)(dian)(dian)機斷電(dian)(dian)(dian)，電(dian)(dian)(dian)磁(ci)(ci)閥電(dian)(dian)(dian)磁(ci)(ci)線圈同(tong)時(shi)(shi)(shi)斷電(dian)(dian)(dian)，電(dian)(dian)(dian)磁(ci)(ci)鐵(tie)芯的(de)磁(ci)(ci)力消失(shi)，彈性架(jia)(jia)受壓縮彈簧反(fan)作用上移(yi)(yi)復位，帶動(dong)(dong)閥芯桿活(huo)塞(sai)離開活(huo)塞(sai)缸底，開啟(qi)通(tong)氣孔。使(shi)(shi)空氣進(jin)(jin)入吸(xi)(xi)液管(guan)腔(qiang)，使(shi)(shi)泵腔(qiang)內的(de)介(jie)質(zhi)與吸(xi)(xi)液管(guan)內的(de)介(jie)質(zhi)隔離，消除虹(hong)吸(xi)(xi)，確保(bao)自(zi)吸(xi)(xi)泵泵腔(qiang)介(jie)質(zhi)貯(zhu)量，以供下次啟(qi)泵時(shi)(shi)(shi)自(zi)吸(xi)(xi)及正常運(yun)行。
三、自控式自吸泵怎么調
1、先打開(kai)控制器罩，然后(hou)平口螺絲刀把中間的(de)調節(jie)旋鈕(niu)順時針向上旋，以獲得更高的(de)斷開(kai)壓力(li)；
2、把壓力罐(guan)上面的加(jia)氣螺母擰(ning)開，用(yong)打氣筒給里(li)面加(jia)入氣體，使其氣壓罐(guan)能(neng)起到穩(wen)壓的作(zuo)用(yong)。
