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(zi)吸泵的(de)組成(cheng)部分之(zhi)一(yi)裝在(zai)吸(xi)(xi)(xi)液口(kou)的(de)(de)進(jin)氣管(guan)(guan)上，啟泵時(shi)電控(kong)閥(fa)密閉(bi)泵體吸(xi)(xi)(xi)液管(guan)(guan)上的(de)(de)進(jin)氣口(kou)，使自吸(xi)(xi)(xi)泵泵腔內(nei)(nei)形(xing)成(cheng)真空，完成(cheng)自吸(xi)(xi)(xi)全過程(cheng)。停泵時(shi)電控(kong)閥(fa)開啟，空氣從密閉(bi)口(kou)進(jin)入，水(shui)泵液管(guan)(guan)內(nei)(nei)迅速隔(ge)離吸(xi)(xi)(xi)液管(guan)(guan)內(nei)(nei)共(gong)流(liu)的(de)(de)介質(zhi)(zhi)，確保(bao)泵腔的(de)(de)介質(zhi)(zhi)不隨吸(xi)(xi)(xi)液管(guan)(guan)腔內(nei)(nei)的(de)(de)介質(zhi)(zhi)回(hui)落到吸(xi)(xi)(xi)液池中，以(yi)達到消除虹(hong)吸(xi)(xi)(xi)的(de)(de)目(mu)的(de)(de)，確保(bao)自吸(xi)(xi)(xi)泵二次自吸(xi)(xi)(xi)時(shi)正常自吸(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)(dian)機啟(qi)動(dong)(dong)(dong)時，電(dian)(dian)(dian)磁閥(fa)同時同步(bu)通電(dian)(dian)(dian)啟(qi)動(dong)(dong)(dong)，電(dian)(dian)(dian)磁鐵芯(xin)吸(xi)(xi)(xi)合(he)銜鐵時帶(dai)動(dong)(dong)(dong)彈(dan)(dan)性架(jia)(jia)下移(yi)，驅動(dong)(dong)(dong)閥(fa)芯(xin)活塞(sai)(sai)桿(gan)向活塞(sai)(sai)缸(gang)體底部(bu)密(mi)封(feng)墊壓(ya)緊，實現密(mi)封(feng)，關閉吸(xi)(xi)(xi)液管(guan)上進氣口通氣孔(kong)，使(shi)(shi)自(zi)吸(xi)(xi)(xi)泵開(kai)始自(zi)吸(xi)(xi)(xi)并進入正常運行(xing)狀態。當停電(dian)(dian)(dian)使(shi)(shi)電(dian)(dian)(dian)機斷電(dian)(dian)(dian)，電(dian)(dian)(dian)磁閥(fa)電(dian)(dian)(dian)磁線圈同時斷電(dian)(dian)(dian)，電(dian)(dian)(dian)磁鐵芯(xin)的磁力(li)消失(shi)，彈(dan)(dan)性架(jia)(jia)受壓(ya)縮(suo)彈(dan)(dan)簧(huang)反作用上移(yi)復位(wei)，帶(dai)動(dong)(dong)(dong)閥(fa)芯(xin)桿(gan)活塞(sai)(sai)離開(kai)活塞(sai)(sai)缸(gang)底，開(kai)啟(qi)通氣孔(kong)。使(shi)(shi)空氣進入吸(xi)(xi)(xi)液管(guan)腔，使(shi)(shi)泵腔內的介質與吸(xi)(xi)(xi)液管(guan)內的介質隔離，消除虹吸(xi)(xi)(xi)，確保自(zi)吸(xi)(xi)(xi)泵泵腔介質貯量，以供(gong)下次(ci)啟(qi)泵時自(zi)吸(xi)(xi)(xi)及正常運行(xing)。
三、自控式自吸泵怎么調
1、先打開控制器罩，然后平(ping)口(kou)螺(luo)絲刀把中(zhong)間的(de)調節旋(xuan)鈕順時針(zhen)向上旋(xuan)，以獲(huo)得更高的(de)斷(duan)開壓力；
2、把(ba)壓力罐上面(mian)的加氣(qi)(qi)螺(luo)母擰開，用(yong)打氣(qi)(qi)筒給里面(mian)加入(ru)氣(qi)(qi)體(ti)，使其氣(qi)(qi)壓罐能起到穩壓的作用(yong)。
