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。電動閥作為自(zi)吸泵的組成部分之(zhi)一裝在吸液(ye)口(kou)(kou)的(de)(de)進(jin)氣管(guan)上,啟泵(beng)(beng)時(shi)電控閥密閉(bi)(bi)泵(beng)(beng)體吸液(ye)管(guan)上的(de)(de)進(jin)氣口(kou)(kou),使自(zi)(zi)吸泵(beng)(beng)泵(beng)(beng)腔內(nei)(nei)形成真空,完成自(zi)(zi)吸全(quan)過程。停泵(beng)(beng)時(shi)電控閥開啟,空氣從密閉(bi)(bi)口(kou)(kou)進(jin)入,水泵(beng)(beng)液(ye)管(guan)內(nei)(nei)迅速隔離吸液(ye)管(guan)內(nei)(nei)共流的(de)(de)介(jie)質(zhi),確保(bao)泵(beng)(beng)腔的(de)(de)介(jie)質(zhi)不隨吸液(ye)管(guan)腔內(nei)(nei)的(de)(de)介(jie)質(zhi)回落到(dao)吸液(ye)池中(zhong),以(yi)達到(dao)消(xiao)除虹(hong)吸的(de)(de)目的(de)(de),確保(bao)自(zi)(zi)吸泵(beng)(beng)二次自(zi)(zi)吸時(shi)正(zheng)常自(zi)(zi)吸及運(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)時,電(dian)(dian)(dian)磁(ci)閥(fa)同時同步(bu)通(tong)電(dian)(dian)(dian)啟動(dong),電(dian)(dian)(dian)磁(ci)鐵(tie)芯吸(xi)(xi)合(he)銜鐵(tie)時帶動(dong)彈(dan)性架(jia)下(xia)移(yi),驅動(dong)閥(fa)芯活塞(sai)桿向活塞(sai)缸體底(di)部密封墊(dian)壓(ya)緊,實(shi)現密封,關閉吸(xi)(xi)液(ye)管(guan)上進氣(qi)口通(tong)氣(qi)孔,使(shi)自(zi)吸(xi)(xi)泵(beng)開始自(zi)吸(xi)(xi)并進入正(zheng)常(chang)運行(xing)狀態。當(dang)停(ting)電(dian)(dian)(dian)使(shi)電(dian)(dian)(dian)機斷(duan)電(dian)(dian)(dian),電(dian)(dian)(dian)磁(ci)閥(fa)電(dian)(dian)(dian)磁(ci)線圈同時斷(duan)電(dian)(dian)(dian),電(dian)(dian)(dian)磁(ci)鐵(tie)芯的(de)(de)磁(ci)力消失,彈(dan)性架(jia)受壓(ya)縮彈(dan)簧反(fan)作用(yong)上移(yi)復位,帶動(dong)閥(fa)芯桿活塞(sai)離開活塞(sai)缸底(di),開啟通(tong)氣(qi)孔。使(shi)空(kong)氣(qi)進入吸(xi)(xi)液(ye)管(guan)腔(qiang)(qiang),使(shi)泵(beng)腔(qiang)(qiang)內的(de)(de)介質(zhi)與吸(xi)(xi)液(ye)管(guan)內的(de)(de)介質(zhi)隔離,消除虹(hong)吸(xi)(xi),確保自(zi)吸(xi)(xi)泵(beng)泵(beng)腔(qiang)(qiang)介質(zhi)貯量,以供下(xia)次啟泵(beng)時自(zi)吸(xi)(xi)及正(zheng)常(chang)運行(xing)。
三、自控式自吸泵怎么調
1、先打開(kai)控制器罩(zhao),然后平口螺(luo)絲刀把中間的調節旋(xuan)鈕順時(shi)針向上旋(xuan),以獲得(de)更高的斷開(kai)壓力;
2、把壓(ya)力罐上面(mian)(mian)的(de)加(jia)氣(qi)螺母擰開,用打氣(qi)筒給里面(mian)(mian)加(jia)入氣(qi)體(ti),使(shi)其氣(qi)壓(ya)罐能起到(dao)穩壓(ya)的(de)作用。
