REXROTH力士乐叶片泵功能特性叶片结构形式
REXROTH叶片泵只不过是离心泵的一种具体应用的泵而命名。实质上砂泵只是一个笼统的叫法。一般主要用在矿业，煤炭，冶金，化工，环保等行业。一般意义的砂泵更多是指用在环保，挖沙，河道清淤等行业较多。这个系列砂泵主要以ES或者G系列的较多。除此之外，叫做砂泵的类型还有很多，石油领域的SB砂泵，矿业上的PS砂泵系列等等。本文介绍的砂泵主要以通常意义上的ES或G系列的挖沙，环保行业的用的砂泵。
REXROTH叶片泵均为卧式、单泵壳结构的离心泵。采用特殊的卡箍夹紧泵体与泵盖，泵的吐出口方向可在360度的任何一个位置，安装使用方便。 砂泵的轴承组件采用圆筒式结构，便于调整叶轮与泵体之间的间隙，维修时可整体拆除。轴承采用油脂润滑。砂泵的轴封形式有填料密封、付叶轮密封、机械密封。砂泵流道宽畅，汽蚀性能好，效率高，耐磨蚀。 传动方式主要有V型三角带传动、弹性联轴器传动、轮减速箱传动、液力偶合器传动、变频驱动装置，可控硅调速等。 过流部件材质采用高硬度的耐磨合金铸铁。
采用多种速度和多种变型方式，使得泵在工况下运行。使用寿命长，运行效益高，能满足多类恶劣的输送条件。是否提供加工定制：否

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完全排出，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Z高，不要完全水平。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
