Causes of Overload and Fever of Shanxi Submersible Pump Motor

Shanxi submersible pump is an important equipment for deep well water lifting. Use the entire unit to work in the water. Extracting groundwater to the surface is used for domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship load transfer, fountain landscape, hot water submersible pump for hot spring bathing, groundwater extraction from deep wells, and water lifting projects such as rivers, reservoirs and canals. It is mainly used for farmland irrigation and water for human and livestock in high mountain areas. It can also be used for central air conditioning cooling, heat pump unit, cold pump unit, city, factory, railway, mine and site drainage. The general flow rate can reach (5m3~650 m3), and the lift can reach 10-550 meters per hour.
Shanxi submersible pump: submersible pump motor overheating burn out reason?
Some customers bought the submersible pump and used it directly without reading the instructions, resulting in the motor burning out. The motor of the submersible pump needs cold water to cool it without heating, so the submersible pump must be placed in the water, and the water must cover the motor so that the motor can be cooled, and then the motor can extend its life.
1. When the submersible pump pumps mud, the overload caused by the increase of medium density. The measured medium density is greater than 1.3, even reaching 1.5~1.6; and the motor power affluence coefficient is small (generally 1.05~1.2).
2. Sediment is deposited in the pump body, and the impeller is overloaded due to braking, and the motor is almost running in a blocked-rotor state.
3. The clearance of the rotor shaft hole and the clearance of the impeller mouth ring are filled with sediment to cause overload caused by the braking of the rotating shaft.
4, individual manufacturers in order to win in the competition, artificially reduce the motor power.
