Submersible pumps are an indispensable tool in the water treatment industry. The life span of submersible pumps is not only related to product quality, but also related to normal use! The following are some points on how to improve the life of submersible pumps:
1. Confirm the correct rotation direction of the motor
Nowadays, there are many types of submersible pumps that can produce water during forward and reverse rotation, but the water output is small and the current is large during reverse rotation, and the long reverse rotation time will damage the motor windings.
2. Prohibit the abnormal power supply voltage
When the voltage is too low, the motor speed of the submersible pump decreases. When it does not reach 70% of the rated speed, the starting centrifugal switch will be closed, causing the starting winding to be energized for a long time and heating or even burning the winding and capacitor. On the contrary, excessive voltage causes the motor to overheat and burn out the windings.
3. Cable installation
When installing the submersible pump, the cable should be overhead and the power cord should not be too long. When the submersible 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. At the same time, debris will enter the pump and damage the pump.
4. Don't let the submersible pump overload for a long time
In order to avoid long-term overload of the submersible pump, do not pump water with a large amount of sand and always observe whether the current value is the value specified on the nameplate. If you find that the current is too large, you should stop the machine for inspection. In addition, the dehydration operation time of the electric pump should not be too long, so as to avoid overheating and burning of the motor.
