故障现象 | 可能产生的原因 | 排除方法 |
1、水泵不出水 | 进水口阀门未打开,进出管路阻塞,叶轮流道阻塞 | 检查,去除阻塞物 |
电机运行方向不对,电机缺相转速很慢 | 调整电机转向,紧固电机接线 | |
吸入管漏气 | 拧紧各密封面,排除空气 | |
泵没灌满液体,泵腔内有空气 | 打开泵上盖或打开排气阀,排尽空气 | |
进口供水不足,吸程过高,底阀漏水 | 停机检查、调整 | |
管路阻力过大,泵选型不当 | 减少管路弯道,重新选泵 | |
2、水泵流量不足 | 先按1原因检查 | 先按1排除 |
管道、泵流道或叶轮部分阻塞,水垢沉积…… | 去除阻塞物,重新调整阀门开度 | |
电压偏低 | 稳压 | |
叶轮磨损 | 更换叶轮 | |
3、功率过大 | 超过额定流量使用 | 调节流量,关小出口阀门 |
吸程过高 | 降低 | |
泵轴承磨损 | 更换轴承 | |
4、杂音振动 | 管路支撑不稳 | 稳固管路 |
液体混有气体 | 提高吸入压力,排气 | |
产生汽蚀 | 降低真空度 | |
轴承损坏 | 更换轴承 | |
电机超载运行 | 调整按5 | |
5、电机发热 | 流量过大,超载运行 | 关小出口阀门 |
局部摩擦 | 检查排除 | |
电机轴承损坏 | 更换轴承 | |
电压不足 | 稳压 | |
6、水泵漏水 | 机械密封磨损 | 更换 |
泵体有砂孔或破裂 | 焊补或更换 | |
密封面不平整 | 修整 | |
安装螺栓松懈 | 紧固 |
