力士乐叶片泵故意障原因加以分析
1）REXROTH叶片泵有些用户水泵启动前未灌满足够水；看上去灌水已从放气孔溢出，但未转动泵轴交空气*排出，致使少许空气还残留进水管或泵体中。
2）REXROTH叶片泵接触进水管水平段逆水流方向应用0.5%以上下降坡度，连接水泵进口一端为zui高，不要*水平。向上翘起，进水管内会存留空气，降低了水管和水泵中真空度，影响吸水。
3）REXROTH叶片泵填料因长期使用已经磨损或填料压过松，造成大量水从填料与泵轴轴套间隙中喷出，其结果是外部空气就从这些间隙进入水泵内部，影响了提水。
4）进水管因长期潜水下，管壁腐蚀出现孔洞，/水泵工作后水面不断下降，当这些孔洞露出水面后，空气就从孔进入了进水管。
5）进水管弯管处出现裂痕，进水管与水泵连接处出现微小间隙，都有可能使空气进入进水管。
水泵转速过低
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。
REXROTH叶片泵工作前，先将泵内充满液体，然后启动离心泵，叶轮快速转动，叶轮的叶片驱使液体转动，液体转动时依靠惯性向叶轮外缘流去，同时叶轮从吸入室吸进液体，在这一过程中，叶轮中的液体绕流叶片，在绕流运动中液体作用一升力于叶片，反过来叶片以一个与此升力大小相等、方向相反的力作用于液体，这个力对液体做功，使液体得到能量而流出叶轮，这时液体的动能与压能均增大。
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，这时，叶轮进口处因液体的排出而形成真空或低压，吸水池中的液体在液面压力（大气压）的作用下，被压入叶轮的进口，于是，旋转着的叶轮就连续不断地吸入和排出液体。
REXROTH叶片泵以其结构简单、使用维修方便、效率较高而成为农业上应用zui广泛一种水泵，但也因提不上水而令人倍感烦恼。现就提不上水这一。
