Small Submersible Slurry Pumps are small and light, and play an important role in farmland irrigation and domestic water for farmhouses. In order to avoid accidents during use, prolong the service life and exert its excellent performance, the following points should be paid attention to when using:

To install a leakage protector. Submersible Slurry Pumps work under water, which is prone to leakage, resulting in power loss and even electric shock accidents. If equipped with a leakage protector, as long as the leakage of the submersible pump exceeds a certain value (generally no more than 30 mA), the leakage protector will cut off the power of the Submersible Slurry Pump to avoid leakage and waste electrical energy and ensure safety.

When installing the Submersible Slurry Pump, the cable should be overhead and the power cord should not be too long. When the Submersible Slurry Pump is launched or lifted, do not apply force to the cable to avoid breaking the power cord. Do not sink into the mud when the submersible pump is working, otherwise it will cause poor heat dissipation of the motor and burn out the motor windings. During installation, the insulation resistance of the motor should not be less than 0.5 megohm.

Try to avoid starting when the power supply voltage is abnormal. The power supply voltage and the rated voltage must not differ by 10%. Excessive voltage will cause the motor to overheat and burn out the windings. If the voltage is too low, the motor speed will decrease. If it does not reach 70% of the rated speed, the start centrifugal switch will be closed, causing the start winding Long time energization will generate heat and even burn out windings and capacitors.

Do not switch the motor frequently. This is because the electric pump will produce backflow when it stops. If it is turned on immediately, the motor load will start, which will cause the starting current to be too large and the winding will burn out.

Do not allow the pump to run excessively for a long time, do not pump water with a large amount of sand, and the dehydration operation time of the Submersible Slurry Pump should not be too long, so as to prevent the motor from overheating and burning. During the operation of the unit, the operator must always observe whether the working voltage and current are within the values specified on the nameplate. If not, the motor should be stopped to find out the cause and eliminate the fault.

The direction of rotation of the motor must be correct. It is necessary to understand the direction of rotation of the motor. There are many types of Submersible Slurry Pumps that can produce water during forward and reverse rotation, but the water output is small and the current is large when reverse rotation, and the reversal time will damage the motor windings.

Always check the motor frequently. If you find any cracks in the lower cover, damage or failure of the rubber seal ring, etc., it should be replaced or repaired in time to avoid water infiltration into the Submersible Slurry Pump.
