深井泵一般由泵体、输水管和泵座组成。除泵座及电机在地面外,泵体和输水管全部在井下,不易检查和拆卸,给故障分析和检修带来困难。为此将本人判断和排除深井泵故障的一点经验介绍如下: 1.开机后出水量一直不足或扬程减小这种情况。首先要检查深井泵外部电压和电机转速是否正常。关机后检查一下用手是否能够转动电机,如有发卡现象,可先调节一下防水罩内的调节螺母,调节螺母每转动一周,叶轮轴向移动1.5～2.0毫米。如电压、转速正常,调节叶轮轴向距离无效,多数是叶轮或进水滤
Deep well pump generally consists of pump body, water pipe and pump seat. In addition to the pump seat and the motor on the ground, the pump body and the water pipe all downhole, not easy to check and disassemble, to the failure analysis and maintenance difficulties. To this end my judgment and troubleshooting of deep well pump a little experience is as follows: 1 boot after the water has been insufficient or head to reduce this situation. First check the deep well pump external voltage and motor speed is normal. After shutdown check whether the hand can turn the motor, if there is a hairpin phenomenon, you can adjust the waterproof nut in the adjustment nut, adjust the nut per rotation, the impeller axial movement of 1.5 to 2.0 mm. Such as voltage, speed normal, adjust the impeller axial distance is invalid, most of the impeller or water filtration
