工作原理

不同種(zhong)類(lei)的(de)(de)(de)電磁(ci)(ci)(ci)閥(fa)；電磁(ci)(ci)(ci)閥(fa)里有密閉(bi)的(de)(de)(de)腔(qiang)，在(zai)不同位置開(kai)有通(tong)孔(kong)，K22JD-15W電控閥(fa)，每個(ge)孔(kong)連接(jie)不同的(de)(de)(de)油管，腔(qiang)中間(jian)是活(huo)(huo)塞(sai)(sai)，兩面是兩塊電磁(ci)(ci)(ci)鐵(tie)，哪面的(de)(de)(de)磁(ci)(ci)(ci)鐵(tie)線(xian)圈(quan)通(tong)電閥(fa)體就(jiu)會被吸(xi)引到哪邊，通(tong)過(guo)控制(zhi)閥(fa)體的(de)(de)(de)移動(dong)(dong)來(lai)開(kai)啟或關閉(bi)不同的(de)(de)(de)排油孔(kong)，電控閥(fa)，而進油孔(kong)是常(chang)開(kai)的(de)(de)(de)，液壓油就(jiu)會進入不同的(de)(de)(de)排油管，然后通(tong)過(guo)油的(de)(de)(de)壓力來(lai)推動(dong)(dong)油缸的(de)(de)(de)活(huo)(huo)塞(sai)(sai)，K22JD-63W電控閥(fa)，活(huo)(huo)塞(sai)(sai)又帶動(dong)(dong)活(huo)(huo)塞(sai)(sai)桿，活(huo)(huo)塞(sai)(sai)桿帶動(dong)(dong)機械(xie)裝(zhuang)置。這樣通(tong)過(guo)控制(zhi)電磁(ci)(ci)(ci)鐵(tie)的(de)(de)(de)電流通(tong)斷就(jiu)控制(zhi)了機械(xie)運動(dong)(dong)。
