Safety Protection Method Of Submersible Pump

Dec 29, 2021

Submersible pump is an important equipment for water extraction in deep wells. When in use, the whole unit works in the water and extracts the groundwater to the surface. It is used for domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship load regulation, and fountain landscape.

The hot water submersible pump is used for bathing in hot springs. It can also be used to extract groundwater from deep wells. It can also be used in water lifting projects such as rivers, reservoirs and canals. It is mainly used for farmland irrigation and human and livestock water in alpine areas. It can also be used for central air conditioning cooling, heat pump unit, cold pump unit, city, factory, railway, mine and construction site drainage. The general flow can reach 5 ~ 650m3 / h and the lift can reach 10-550m.

Submersible pumps often burn out motor windings due to lack of water in the pool. In view of this situation, we have sorted out several protective measures for submersible pumps for you today.

1. Abnormal power supply voltage is prohibited

2. Confirm the correct rotation direction of the motor

3. Insulation resistance requirements for cable installation and submersible pump

4. Avoid frequent switching

5. Installation of leakage protector

6. It is forbidden to overload the submersible pump for a long time

7. Pay attention to daily maintenance

8. Try to avoid starting at low voltage
