REXROTH葉片泵本身機(jī)械故障。葉輪與泵軸緊固螺母松脫或泵軸變形彎曲，造成葉輪多移，直接與泵體摩擦，或軸承損壞，都有可能降低水泵轉(zhuǎn)速。

    REXROTH葉片泵電動(dòng)機(jī)因繞組燒毀，而失磁，維修中繞組匝數(shù)、線徑、接線方法改變，或維修中故障未*排除因素也會(huì)使水泵轉(zhuǎn)速改變。

    REXROTH葉片泵依靠旋轉(zhuǎn)葉輪對(duì)液體的作用把原動(dòng)機(jī)的機(jī)械能傳遞給液體。由于離心泵的作用液體從葉輪進(jìn)口流向出口的過程中，其速度能和壓力能都得到增加，被葉輪排出的液體經(jīng)過壓出室，大部分速度能轉(zhuǎn)換成壓力能，然后沿排出管路輸送出去。

    REXROTH葉片泵主要用于由于顆粒太大以至于一般渣漿泵不能輸送的強(qiáng)磨蝕性物料的連續(xù)輸送。適用于挖泥、吸砂礫、疏浚河道、采礦及金屬冶煉爆渣輸送等。

上海維特銳在德國與REXROTH合作，可長期穩(wěn)定供應(yīng)力士樂葉片泵，力士樂電磁閥，REXROTH導(dǎo)軌，力士樂柱塞泵等產(chǎn)品
