微型泵体小轻便,深受用户欢迎,农村,城镇广泛使用。但是,有的用户反映,微型泵在使用中常发生故障,现将常见故障的发生原因和排除方法介绍如下:一、电机发热水泵使用扬程太低,流量猛增,电机发热。可在出水管上增设阀门截流、降低流量。若叶轮与泵壳摩擦严重,或导线细长,电压不足,可调整、修复、减少摩擦,增大电压。二、电机不转原因有叶轮卡死,泵轴弯曲,保险丝烧断,定子绕组烧断,开关接触不好等。排除时,可 Mini pump small light, welcomed by users, rural areas, towns and cities widely used. However, some users reflect that the mini-pump often fails in use. Now the causes and solutions of the common faults are introduced as follows: 1. The use of the motor-driven heating pump is too low, the flow surge, and the motor generates heat. Can be added in the outlet pipe shut-off valve to reduce traffic. If the impeller and the pump shell friction serious, or wire slender, voltage shortage, adjustable, repair, reduce friction, increase the voltage. Second, the motor does not turn due to the impeller stuck, the pump shaft bending, fuse blown, stator winding blown, switch contact is not good. When excluded, may
