REXROTH叶片泵本身机械故障。叶轮与泵轴紧固螺母松脱或泵轴变形弯曲，造成叶轮多移，直接与泵体摩擦，或轴承损坏，都有可能降低水泵转速。

    REXROTH叶片泵电动机因绕组烧毁，而失磁，维修中绕组匝数、线径、接线方法改变，或维修中故障未*排除因素也会使水泵转速改变。

    REXROTH叶片泵依靠旋转叶轮对液体的作用把原动机的机械能传递给液体。由于离心泵的作用液体从叶轮进口流向出口的过程中，其速度能和压力能都得到增加，被叶轮排出的液体经过压出室，大部分速度能转换成压力能，然后沿排出管路输送出去。

    REXROTH叶片泵主要用于由于颗粒太大以至于一般渣浆泵不能输送的强磨蚀性物料的连续输送。适用于挖泥、吸砂砾、疏浚河道、采矿及金属冶炼爆渣输送等。
