深井泵是单吸、多级立式离心泵．当水深度超过8m时，即需要深井泵提水。深井泵较其他水泵的结构复杂，这给故障排除带来许多困难。在深井系的故障中．振动的故障最为常见。因此．必须分析深井泵产生振动的原因并及时排除。呈螺栓松动基础不牢螺栓连接松动，则会引起泵组振动， Deep well pump is a single suction, multi-stage vertical centrifugal pump. When the water depth exceeds 8m, deep well pump is required. Deep well pumps have a more complicated structure than other pumps, which presents many difficulties for troubleshooting. In the deep well system failure. The most common vibration fault. therefore. It is necessary to analyze the causes of deep well pump vibration and eliminate it in time. Loose bolts are loose foundation loose bolt connection loose, it will cause the pump group vibration,
