What To Pay Attention To When Using Submersible Pumps?
Pay attention to the cooling condition
Make sure the submersible pump is submerged in water
Once the submersible pump fails, do not disassemble it by yourself
During the non-use period, Lift the submersible pump away from the water source
1.Submersible pumps generally have requirements for the upper and lower deviation ranges of power supply voltage and frequency, and areas with unstable power supplies should be carefully observed to prevent damage. For high-power submersible pumps, adopt step-down start or soft start to reduce the impact on low-voltage electrical equipment, instruments, automatic control systems and submersible pumps near the power grid. Submersible pumps from Zhejiang Dolay pump industry generally have requirements for the solid content and solid particle diameter, pH value, water temperature, chloride ion content, etc. in the transported liquid, and care should be taken during use to avoid damage. During operation, the submersible pump should be submerged in water, We should pay attention to the cooling condition of the cooling water, so as to facilitate the heat dissipation of the submersible pump.
2.The submersible pump control submersible level gauge and the floating ball should be installed in a proper position. It is necessary to avoid the accumulation of sediment when the level is too low, which will cause the liquid level gauge to fail to detect the water level or reduce the accuracy. Make sure the submersible pump is still submerged.
If the submersible pump is out of service for a long time, it should be hoisted, the discharge port should be cleaned, all the accumulated water in the cooling jacket should be drained and the sediment should be cleaned (especially important in cold winter to prevent the motor from freezing), and the inside and outside of the motor water pump should be scrubbed Clean, carry out comprehensive paint and anti-rust treatment, if conditions permit, butter can be applied to key parts of the pump, and lubricating oil can be added to the bearings to prevent parts from rusting. After treatment, store in a non-corrosive and dry and ventilated warehouse . If it is placed in water, run it at least once every few days for no less than 30 minutes.
3. Once the submersible pump fails, do not disassemble it by yourself. Because when disassembling by yourself, one is
I don't know where the fault is, so I blindly disassemble it; the second is that there is no special tool, which often damages the original intact parts.
The best way is to repair at an experienced and large-scale maintenance point, and replace the "overage" in time.
Parts and certain wearing parts. Under normal circumstances, the submersible pump should be repaired every six months to prevent working with "sickness".
4. During the non-use period, Lift the submersible pump away from the water source in time, and the accumulated water in the pump should be drained, especially in cold winter. Then put it in a dry place, and qualified users can also paint yellow on the key parts of the submersible pump. add lubricating oil to the bearing to prevent parts from rusting.
In addition, the non-use period of the submersible pump does not exceed the longer the better. If it is not used for a long time, it will not only easily corrode the parts, but also reduce the service life of the submersible pump.
Understanding the precautions for the use of submersible well pumps can help you use and maintain them better, prolong their service life, and improve work efficiency.
