力士乐Rexroth简介

力士乐柱塞泵为博世-力士乐Bosch Rexroth旗下品牌，是世界高科技企业之一，50多年来，Bosch Rexroth集团及Bosch Rexroth公司的业务部门致力开发专业型液压传动领域高科技产品，产品和品牌已享誉。力士乐的产品，目前没有其他的品牌能向顾客提供所有传动与控制技术，专门化与一体化并举。正因如此，博世-力士乐在液压传动、控制及移动技术等领域成为了世界性的榜样。

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。

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

1)人为因素。有相当一部分用户因原配电动机损坏，就随意配上另一台电动机带动，结果造成了流量少、扬程低抽不上水后果。

2)传动带磨损。有许多大型离水泵采用带传,因长期使用,传动带磨损而松也,出现打滑现象，降低了水泵转速。

3)安装不当。两带轮中心距太小或两轴不太平行，传动带紧边安装到上面，致使包角太轴偏心距较大等，均会造成水泵转速变化。

4)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。

5)动力机维修不录。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，或维修中故障未彻底排除因素也会使水泵转速改变。

6)吸程太大。有些水源较深，有些水源围势较平坦处，而忽略了水泵容许吸程，产生了吸水少或根本吸不上水结果。要知道水泵吸水口处能建立真空度是有限度，真空时吸程约为10米水柱高，而水泵不可能建立真空。真空度过大，易使泵内水气化，对水泵工作不利。各离心泵都有其大容许吸程，一般3~8.5米之间，安装水泵时切不可只图方便简单。

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，所以选用一台按生产实际需要，合理可靠的螺杆泵既能保证生产顺利进行，又可降低修理成本。
