力士乐VT-MSPA1-508-10/V0REXROTH放大器
Rexroth伺服阀放大板的结构和原理如图所示,无信号电流输入时,衔铁和挡板处于中间位置。这时喷嘴4二腔的压力pa=pb,滑阀7二端压力相等,滑阀处于零位。输入电流后,电磁力矩使衔铁2连同挡板偏转θ角。设θ为顺时针偏转,则由于挡板的偏移使pa>pb,滑阀向右移动。滑阀的移动,通过反馈弹簧又带动挡板和衔铁反方向旋转(逆时针),二喷嘴压力差又减小。在衔铁的原始平衡位置(无信号时的位置)附近,力矩马达的电磁力矩、滑阀二端压差通过弹簧作用于衔铁的力矩以及喷嘴压力作用于挡板的力矩三者取得平衡,衔铁就不再运动。同时作用于滑阀上的油压力与反馈弹簧变形力相互平衡,滑阀在离开零位一段距离的位置上定位。这种依靠力矩平衡来决定滑阀位置的方式称为力反馈式。如果忽略喷嘴作用于挡板上的力,则马达电磁力矩与滑阀二端不平衡压力所产生的力矩平衡,弹簧也只是受到电磁力矩的作用。因此其变形,也就是滑阀离开零位的距离和电磁力矩成正比。
