Common faults of submersible pumps

In use, submersible pumps often encounter problems such as low impeller speed, low flow, impeller non-rotation, oil leakage, and electric leakage, resulting in reduced work efficiency.

1.叶轮速度较低,头部不能be reached: When we first bought the submersible pump, we often try it out, but during the trial process, we will find that the actual head does not reach the standard head and the impeller speed is also very low. In this case, please don't panic. The wiring may be incorrect. It is recommended to change the fire line. It is also possible that the submersible pump is inferior and the head cannot be reached. Therefore, it is recommended to buy high-quality products.　　

2.潜水泵的产出和弱水雷竞技官网最新版low flow rate: take out the submersible pump and check that the rotor can rotate flexibly, and the rotor can rotate when energized. The pump was disassembled and checked, and it was found that there was looseness between the lower shaft and the bearing of the submersible pump, and the rotor moved down, so the rotor was weak and the output power was small. Use a suitable gasket to pad between the rotor and the bearing to move the rotor upward, install the test machine, and the fault can be eliminated.　　

3. After power on, the impeller does not rotate: If the submersible pump is humming after power on, the impeller does not rotate. Please cut off the power and move the impeller at the water inlet. If it does not move, it means that the rotor is stuck. If the impeller can be turned, but the impeller does not rotate after power on, the cause of the fault may be that the bearing is severely worn, and the magnetism generated by the stator when the power is on attracts the rotor and cannot rotate. Replace the bearing and then assemble the water pump, move the impeller flexibly, and troubleshoot.　

4. Oil leakage: The oil leakage of the submersible pump is mainly due to the serious abrasion of the sealing box, causing oil leakage in the oil chamber of the sealing box or poor sealing at the outlet box.　　

5. Leakage: Leakage is the most common failure of submersible pumps, and it is also one of the most dangerous factors that endanger personal safety. So pay special attention. The fault phenomenon is that when the switch knife is closed, the leakage protector in the transformer power distribution room will trip (if there is no leakage protector, it will be very dangerous and cause the motor to burn out).
