REXROTH電磁閥中國區(qū)銷售商
REXROTH電磁閥里有密閉的腔，在不同位置開有通孔，每個孔連接不同的油管，腔中間是活塞，兩面是兩塊電磁鐵，哪面的磁鐵線圈通電閥體就會被吸引到哪邊，通過控制閥體的移動來開啟或關(guān)閉不同的排油孔，而進(jìn)油孔是常開的，液壓油就會進(jìn)入不同的排油管，然后通過油的壓力來推動油缸的活塞，活塞又帶動活塞桿，活塞桿帶動機(jī)械裝置。這樣通過控制電磁鐵的電流通斷就控制了機(jī)械運(yùn)動。
1、REXROTH電磁閥從原理上分為三大類：
1）REXROTH直動式電磁閥：
原理：通電時，電磁線圈產(chǎn)生電磁力把關(guān)閉件從閥座上提起，閥門打開；斷電時，電磁力消失，彈簧把關(guān)閉件壓在閥座上，閥門關(guān)閉。
特點(diǎn)：在真空、負(fù)壓、零壓時能正常工作，但通徑一般不超過25mm。
2）REXROTH分步直動式電磁閥：
原理：它是一種直動和先導(dǎo)式相結(jié)合的原理，當(dāng)入口與出口沒有壓差時，通電后，電磁力直接把先導(dǎo)小閥和主閥關(guān)閉件依次向上提起，閥門打開。當(dāng)入口與出口達(dá)到啟動壓差時，通電后，電磁力先導(dǎo)小閥，主閥下腔壓力上升，上腔壓力下降，從而利用壓差把主閥向上推開；斷電時，先導(dǎo)閥利用彈簧力或介質(zhì)壓力推動關(guān)閉件，向下移動，使閥門關(guān)閉。
特點(diǎn)：在零壓差或真空、高壓時亦能可*動作，但功率較大，要求必須水平安裝。
3）REXROTH先導(dǎo)式電磁閥：
原理：通電時，電磁力把先導(dǎo)孔打開，上腔室壓力迅速下降，在關(guān) 閉件周圍形成上低下高的壓差，流體壓力推動關(guān)閉件向上移動，閥門打開；斷電時，彈簧力把先導(dǎo)孔關(guān)閉，入口壓力通過旁通孔迅速腔室在關(guān)閥件周圍形成下低上高的壓差，流體壓力推動關(guān)閉件向下移動，關(guān)閉閥門。
特點(diǎn)：流體壓力范圍上限較高，可任意安裝（需定制）但必須滿足流體壓差條件。
2、REXROTH電磁閥從閥結(jié)構(gòu)和材料上的不同與原理上的區(qū)別，分為六個分支小類：直動膜片結(jié)構(gòu)、分步直動膜片結(jié)構(gòu)、先導(dǎo)膜片結(jié)構(gòu)、直動活塞結(jié)構(gòu)、分步直動活塞結(jié)構(gòu)、先導(dǎo)活塞結(jié)構(gòu)。
