潜水电泵扬程范围广,可以从几米到上千米。排水量也可做得很大,每小时几方到几千方,泵与电机一起潜入水中使用,噪音小、效率高、节约电源,无需灌引水,合闸即抽水,使用维修方便,因而在我国农村灌溉、排水中应用十分广泛。潜水电泵由于产品制造的质量、选型和安装的不正确,操作和维护的不当或者长期使用后零部件的磨损和电机与电缆绝缘材料的老化变质等原因会引起故障。电泵出故障后应及时地查明原因加以排除,才能继续使用,否则会造成事故。现将电泵常见的故障及其处理方法列举如下:
Submersible pump lift a wide range, from a few meters to kilometers. Drainage can also be done a lot, a few square every few days to thousands of square, pumps and motors dive into the water use, low noise, high efficiency, save power, without irrigation, closing that pumping, easy to use and maintenance, and therefore in our country Rural irrigation, drainage is widely used. Submersible pumps can cause malfunctions due to the quality of the manufactured products, improper selection and installation, improper operation and maintenance, wear and tear of parts after long-term use, and deterioration of insulation materials of motors and cables. Electric pump out of the fault should promptly identify the reasons to be ruled out to continue to use, otherwise it will cause accidents. Now the common pump failure and its treatment are as follows:
