A11VLO145LE2S5/11R-NZG12N00-S柱塞液压泵河北唐山柱塞泵的工作原理

   柱塞泵是液压系统的一个重要装置。它依靠柱塞在缸体中往复运动，使密封工作容腔的容积发生变化来实现吸油、压油。柱塞泵具有额定压力高、结构紧凑、效率高和流量调节方便等优点，被广泛应用于高压、大流量和流量需要调节的场合，诸如液压机、工程机械和船舶中。

   柱塞泵是往复泵的一种，属于体积泵，其柱塞靠泵轴的偏心转动驱动，往复运动，其吸入和排出阀都是单向阀。当柱塞外拉时，工作室内压力降低，出口阀关闭，低于进口压力时，进口阀打开，液体进入;柱塞内推时，工作室压力升高，进口阀关闭，高于出口压力时，出口阀打开，液体排出。当传动轴带动缸体旋转时，斜盘将柱塞从缸体中拉出或推回，完成吸排油。

先导型电磁阀工作原理,台鸣公司为您呈现原理：通电时，电磁力驱动先导阀打开先导阀，主阀上腔压力迅速下降，在主阀上下腔内形成压差，依靠介质压力推动主阀关闭件上移，阀门开启；断电时，弹簧力把先导阀关闭，入口介质压力通过节流孔迅速进入主阀上腔在上腔内形成压差，从而使主阀关闭。特点：体积小，功率低，但介质压差范围受限，必须满足压差条件（.1MPa)。适用范围：四两拨千斤，先导电磁阀正是根据这个道理，比较适合于大口径，高压力工况下使用。
