No, do not let the electric pump run under overload for a long time. The dehydration operation time of the electric pump should not be too long to avoid overheating and burning of the motor. During the operation of the unit, the operator must always observe whether the working voltage and current are within the specified values on the nameplate. If they do not meet the requirements, the motor should be stopped to identify the cause and troubleshoot.

Precautions for using fish tank submersible pumps:

1. It is necessary to understand the direction of rotation of the motor. Some types of submersible pumps can produce water during both forward and reverse rotation, but during reverse rotation, the water output is small and the current is high, which can damage the motor winding. To prevent electric shock accidents caused by leakage during underwater operation of submersible pumps, a leakage protection switch should be installed.

2. When choosing a submersible pump, attention should be paid to its model, flow rate, and head. If the selected specifications are not appropriate, sufficient water output cannot be obtained and the efficiency of the unit cannot be fully utilized.

3. When installing a submersible pump, the cable should be overhead and the power cord should not be too long. When the unit is launched, do not force the cables to avoid causing power cord breakage. Do not sink the submersible pump into the mud during operation, otherwise it may cause poor heat dissipation of the motor and burn out the motor winding.

4. Try to avoid starting up at low voltage. Do not frequently switch on and off the motor, as it will generate backflow when the electric pump stops running. If turned on immediately, it will cause the motor to start with a load, resulting in excessive starting current and burning out the winding.
