水泵的常见故障，大体上可分为水力故障和机械故障两类。出现故障，应及时检查、排除，不可使机器“带病”工作。排除故障的程序是：弄清现象—→分析原因—→加以排除。 离心泵在运行中，水泵出水量不足。原因： 1、吸水管淹没不够深，泵内吸入； 2、吸水管接头处漏气、漏水； 3、吸水管或叶轮有水草杂物； 4、输水高度过高； 5、密封填料漏气； 6、水扬程过高； 7、转速不够； 8、吸水管道突然被杂物堵塞； 9、被吸入杂物缠塞或被打坏； 10、管口吸入大量空气排除方法： 1.增加吸水管长度，水面上放一块木板，阻止空气进入水管 2.拧紧连接螺丝或更换胶垫 3.xx水草杂物 4.降低输水高度或关小压水管上的闸阀 5.旋紧压盖或更换填料 6.调整吸水扬程或关小闸阀 7.调整传动皮带的松紧度离心泵在运行中，水泵突然停止出水 8.停机后xx堵塞物 9.停机后，拆开水泵，xx杂物或更换叶轮 10.加深吸水管淹没深度 总而言之，水泵故障原因是多方面的，要作认真细致的分析，不要忙于拆卸机件。应该遵循“先外部、后内部”的原则检查，找出原因，“对症下药”，排除故障。

Common pump failures, in general can be divided into two types of hydraulic failure and mechanical failure. Failure, it is timely inspection, exclusion, not the machine "sick" work. Troubleshooting procedure is: understand the phenomenon - → analyze the reasons - → to be eliminated. Centrifugal pumps in operation, pumping out the water shortage. Reason: 1, suction pipe submerged deep enough, pump suction; 2, suction pipe joints Department leakage, leakage; 3, suction tube or the impeller with grass debris; 4, water height is too high; 5, sealing packing leakage; 6, water lift too high; 7, speed is not enough; 8, suction pipe suddenly debris blockage; 9, sucked debris wrapped around Cyprus or bash; 10, possession of a large number of air inhalation Remedy: 1. Increase the suction tube length, placed on a wood surface to prevent air entering pipe 2. Tighten connections or replace the pad screws 3. Clear water plant debris 4. Reduce the water pressure high or off a small valve on the water 5. Tighten or replace the packing gland 6. To adjust suction head on or off a small valve 7. To adjust belt tightness drive centrifugal pumps in operation, the water pump suddenly stops 8. Downtime for the removal plug material 9. Shutdown, the pump apart, removing debris or replacement of the impeller 10. Plus a deep water submergence depth In short, pump failure are many reasons, and to make careful and detailed analysis, not busy dismantling parts. Should follow the "first outside, after the internal" principle of inspection, find out the reasons, "the right medicine," troubleshooting.
