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)動閥作為(wei)自吸(xi)泵的組成(cheng)部分之一裝在吸(xi)(xi)(xi)液(ye)(ye)口的進(jin)氣管(guan)(guan)(guan)上，啟泵時(shi)電控(kong)閥密閉泵體吸(xi)(xi)(xi)液(ye)(ye)管(guan)(guan)(guan)上的進(jin)氣口，使(shi)自(zi)吸(xi)(xi)(xi)泵泵腔(qiang)(qiang)內(nei)形成(cheng)真空，完成(cheng)自(zi)吸(xi)(xi)(xi)全過程。停(ting)泵時(shi)電控(kong)閥開啟，空氣從密閉口進(jin)入，水泵液(ye)(ye)管(guan)(guan)(guan)內(nei)迅速隔離吸(xi)(xi)(xi)液(ye)(ye)管(guan)(guan)(guan)內(nei)共(gong)流(liu)的介質，確保(bao)泵腔(qiang)(qiang)的介質不隨吸(xi)(xi)(xi)液(ye)(ye)管(guan)(guan)(guan)腔(qiang)(qiang)內(nei)的介質回落到吸(xi)(xi)(xi)液(ye)(ye)池中，以(yi)達到消除(chu)虹吸(xi)(xi)(xi)的目(mu)的，確保(bao)自(zi)吸(xi)(xi)(xi)泵二次自(zi)吸(xi)(xi)(xi)時(shi)正常自(zi)吸(xi)(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)機啟(qi)動(dong)時，電(dian)(dian)磁(ci)閥同(tong)時同(tong)步通(tong)(tong)電(dian)(dian)啟(qi)動(dong)，電(dian)(dian)磁(ci)鐵(tie)芯吸(xi)合銜鐵(tie)時帶動(dong)彈(dan)性(xing)架下移，驅(qu)動(dong)閥芯活塞桿(gan)向(xiang)活塞缸體底部密封(feng)墊壓緊，實現密封(feng)，關閉吸(xi)液管上(shang)進氣(qi)(qi)口通(tong)(tong)氣(qi)(qi)孔，使(shi)自(zi)(zi)吸(xi)泵(beng)開始(shi)自(zi)(zi)吸(xi)并進入正(zheng)常運(yun)(yun)行狀態(tai)。當停(ting)電(dian)(dian)使(shi)電(dian)(dian)機斷電(dian)(dian)，電(dian)(dian)磁(ci)閥電(dian)(dian)磁(ci)線圈同(tong)時斷電(dian)(dian)，電(dian)(dian)磁(ci)鐵(tie)芯的磁(ci)力消失，彈(dan)性(xing)架受(shou)壓縮彈(dan)簧反作用上(shang)移復位(wei)，帶動(dong)閥芯桿(gan)活塞離開活塞缸底，開啟(qi)通(tong)(tong)氣(qi)(qi)孔。使(shi)空氣(qi)(qi)進入吸(xi)液管腔，使(shi)泵(beng)腔內的介(jie)質與(yu)吸(xi)液管內的介(jie)質隔(ge)離，消除(chu)虹(hong)吸(xi)，確保自(zi)(zi)吸(xi)泵(beng)泵(beng)腔介(jie)質貯量，以供下次啟(qi)泵(beng)時自(zi)(zi)吸(xi)及正(zheng)常運(yun)(yun)行。
三、自控式自吸泵怎么調
1、先打開控制器罩(zhao)，然后平口螺(luo)絲刀把(ba)中間的(de)調節旋鈕順(shun)時(shi)針(zhen)向上旋，以獲得更高的(de)斷開壓力；
2、把壓(ya)力罐上面的加氣(qi)螺母(mu)擰開，用打(da)氣(qi)筒給(gei)里面加入氣(qi)體，使其氣(qi)壓(ya)罐能(neng)起(qi)到穩壓(ya)的作(zuo)用。
