香港力士樂電磁閥,R900556323 4WE6J1-6X/EG24N9K4

特點(diǎn)： 在零壓差或真空、高壓時(shí)亦能可動(dòng)作，但功率較大，要求必須安裝
德國REXROTH力士樂先導(dǎo)式電磁閥：
 原理：通電時(shí)，電磁力把先導(dǎo)孔打開，上腔室壓力迅速下降，在關(guān)閉件周圍形成上下高的壓差，流體壓力推動(dòng)關(guān)閉件向上移動(dòng)，閥門打開；斷電時(shí)，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)閥件周圍形成下上高的壓差，流體壓力推動(dòng)關(guān)閉件向下移動(dòng)，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 。

 力士樂REXROTH電磁閥里有密閉的腔，在的不同位置開有通孔，每個(gè)孔都通向不同的油管，腔中間是閥，兩面是兩塊電磁鐵，哪面的磁鐵線圈通電閥體就會(huì)被吸引到哪邊，通過控制閥體的移動(dòng)來檔住或漏出不同的排油的孔，而進(jìn)油孔是常開的，液壓油就會(huì)進(jìn)入不同的排油管，然后通過油的壓力來推動(dòng)油剛的活塞，活塞又帶動(dòng)活塞桿，活塞竿帶動(dòng)機(jī)械裝置動(dòng)。這樣通過控制電磁鐵的電流就控制了機(jī)械運(yùn)動(dòng)。
