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(fa)作(zuo)為自吸泵(beng)的(de)組成(cheng)(cheng)部分之一裝(zhuang)在吸(xi)(xi)液口(kou)(kou)的(de)進(jin)氣管(guan)上，啟泵時電控閥密(mi)閉泵體吸(xi)(xi)液管(guan)上的(de)進(jin)氣口(kou)(kou)，使自吸(xi)(xi)泵泵腔內(nei)(nei)形成(cheng)(cheng)真空，完(wan)成(cheng)(cheng)自吸(xi)(xi)全過程。停泵時電控閥開(kai)啟，空氣從密(mi)閉口(kou)(kou)進(jin)入，水泵液管(guan)內(nei)(nei)迅速隔(ge)離吸(xi)(xi)液管(guan)內(nei)(nei)共流的(de)介質(zhi)，確保(bao)泵腔的(de)介質(zhi)不隨吸(xi)(xi)液管(guan)腔內(nei)(nei)的(de)介質(zhi)回落到(dao)吸(xi)(xi)液池中(zhong)，以達到(dao)消除虹吸(xi)(xi)的(de)目的(de)，確保(bao)自吸(xi)(xi)泵二(er)次自吸(xi)(xi)時正常自吸(xi)(xi)及運(yun)行(xing)。
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)(dian)(dian)(dian)機(ji)啟(qi)動(dong)時(shi)，電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥同時(shi)同步通(tong)電(dian)(dian)(dian)(dian)(dian)(dian)啟(qi)動(dong)，電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)鐵(tie)芯吸(xi)合銜鐵(tie)時(shi)帶動(dong)彈性(xing)架(jia)下(xia)移，驅動(dong)閥芯活塞桿向(xiang)活塞缸(gang)體(ti)底部密封(feng)墊(dian)壓緊，實現密封(feng)，關(guan)閉吸(xi)液(ye)(ye)管上進(jin)氣口通(tong)氣孔，使自(zi)吸(xi)泵開(kai)始自(zi)吸(xi)并進(jin)入正(zheng)常(chang)運(yun)行(xing)狀態。當停(ting)電(dian)(dian)(dian)(dian)(dian)(dian)使電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)斷(duan)電(dian)(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)線圈同時(shi)斷(duan)電(dian)(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)鐵(tie)芯的磁(ci)(ci)力消失，彈性(xing)架(jia)受壓縮彈簧反(fan)作用上移復位，帶動(dong)閥芯桿活塞離(li)(li)開(kai)活塞缸(gang)底，開(kai)啟(qi)通(tong)氣孔。使空(kong)氣進(jin)入吸(xi)液(ye)(ye)管腔，使泵腔內的介質與吸(xi)液(ye)(ye)管內的介質隔(ge)離(li)(li)，消除虹吸(xi)，確保自(zi)吸(xi)泵泵腔介質貯量，以供下(xia)次啟(qi)泵時(shi)自(zi)吸(xi)及正(zheng)常(chang)運(yun)行(xing)。
三、自控式自吸泵怎么調
1、先(xian)打開(kai)(kai)控制器罩，然(ran)后平口(kou)螺絲刀把中間的調節(jie)旋鈕順時針向上(shang)旋，以獲(huo)得(de)更高(gao)的斷開(kai)(kai)壓力；
2、把壓(ya)力(li)罐上面的(de)加(jia)氣(qi)螺母擰(ning)開，用打(da)氣(qi)筒給里(li)面加(jia)入氣(qi)體(ti)，使(shi)其氣(qi)壓(ya)罐能起到穩壓(ya)的(de)作(zuo)用。
