力士樂電磁閥按原理分為: 直(zhi)動式(shi)、分(fen)布直(zhi)動式(shi)、先導式(shi)三大類;按(an)結(jie)構分(fen)為膜片式(shi)電磁閥和活(huo)塞式(shi)電磁閥兩類。 力士樂電磁閥工作原理: 電磁(ci)閥(fa)(fa)里有密閉的(de)(de)腔,在的(de)(de)不(bu)同位置開(kai)有通(tong)孔,每(mei)個孔都通(tong)向不(bu)同的(de)(de)油(you)(you)管(guan),腔中(zhong)間是閥(fa)(fa),兩(liang)面是兩(liang)塊電磁(ci)鐵,哪面的(de)(de)磁(ci)鐵線圈通(tong)電閥(fa)(fa)體就(jiu)會被吸(xi)引(yin)到(dao)哪邊,通(tong)過控制(zhi)閥(fa)(fa)體的(de)(de)移(yi)動(dong)(dong)(dong)來檔住或漏出不(bu)同的(de)(de)排油(you)(you)的(de)(de)孔,而進油(you)(you)孔是常(chang)開(kai)的(de)(de),液壓油(you)(you)就(jiu)會進入不(bu)同的(de)(de)排油(you)(you)管(guan),然后通(tong)過油(you)(you)的(de)(de)壓力來推動(dong)(dong)(dong)油(you)(you)缸的(de)(de)活(huo)(huo)塞,活(huo)(huo)塞又帶動(dong)(dong)(dong)活(huo)(huo)塞桿,活(huo)(huo)塞竿帶動(dong)(dong)(dong)機械(xie)裝置動(dong)(dong)(dong)。這樣(yang)通(tong)過控制(zhi)電磁(ci)鐵的(de)(de)電流(liu)就(jiu)控制(zhi)了機械(xie)運(yun)動(dong)(dong)(dong)。 力士樂直動式電磁閥工作原理: 通電時(shi),電磁線圈產生電磁力把關(guan)閉件從閥(fa)座上提起,閥(fa)門(men)打開;斷(duan)電時(shi),電磁力消失,彈簧把關(guan)閉件壓在閥(fa)座上,閥(fa)門(men)關(guan)閉。 力士樂分布直動式電磁閥工作原理:
