5 factors that cause submersible sand pump over heat
Submersible sand pump, also known as submersible sediment pump, submersible mud pump, submersible sand pump, submersible suction pump, submersible pump, underwater dredging pump, etc., China Do Pump is a manufacturer of sand pump. dredge pump, electric submersible sand pump and hydraulic submersible dredge pump with relative dredging equipment.
It is normal for the machine to run hot for a long time, especially in summer, but if the submersible sand pump is abnormally hot, then it needs to be resolved. Let's take a look at the submersible sand pump's heat. 5 factors, we must know why they are.
1. For submersible sand pumps, the overload of the submersible sand pump results in excessive motor load torque, and then the motor current increases!
2. High head is used for low head, which refers to a pump with a faster rated speed and a smaller fan blade instead of a pump that should have a slower rated speed and a larger fan blade.
3. For a high-lift submersible sand pump, if the actual situation does not require such a high pressure, then the sand pump will run at a low head. At this time, the flow of the submersible sand pump will be higher than the rated high-lift The flow is large, and the power at this time is higher than that at the rated high head, so it is easy to overload.
4. Both the head and the flow are determined by the speed of the motor. After the power is set, increasing the flow by increasing the speed will also cause the head to increase, which does not comply with energy conservation. Therefore, increasing the flow can only be achieved by increasing the size of the fan blades and then diving. The load torque of the motor shaft of the pump becomes larger, the motor speed decreases, the head decreases, and the flow rate also decreases. However, the comprehensive fan blades become larger and should still increase.
5. The submersible sand pump has a premise that overload and heat generation are prerequisite. That is, there is no gate valve adjustment at the outlet. The operating point of the pump is determined entirely by the intersection of the pipeline characteristic curve and the pump characteristic curve.
