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。

    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。

    进水管因长期潜水下，管壁腐蚀出现孔洞，REXROTH叶片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。

    REXROTH叶片泵因其有可变量输送、自吸能力强、可逆转、能输送含固体颗粒的液体等特点，在污水处理厂中，广泛地被使用在输送水、湿污泥和絮凝剂药液方面。螺杆泵选用应遵循经济、合理、可靠的原则。

    如果在设计选型方面考虑不周，会给以后的使用、管理、维修带来麻烦，所以选用一台合理可靠的力士乐叶片泵既能保证生产顺利进行，又可降低修理成本。
