1、 Precautions for purchasing submersible pump

1. Buy from regular and large agricultural machinery shopping malls Regular shopping malls have strict control over product quality and good reputation. Even in case of quality problems, they can negotiate with distributors

2. Purchase products The product has been tested by the market. It is a product with reliable quality, so it is more reassuring to buy it

3. Check whether the nameplate identification is complete The nameplate shall be fixed on the obvious part of the water pump, and shall indicate the manufacturer's name, address, submersible sewage pump, magnetic drive circulating pump, name, model, specified flow, specified head, supporting pipe inner diameter, rated power, rated frequency, rated voltage, current, synchronous speed, phase number, insulation grade, factory number or factory date, electric pump weight, product standard number Product license number, etc The steering direction shall also be marked on the electric pump If there are no or incomplete marks on the product identification of these items that should be marked, such pumps should not be purchased

4. Check whether the manufacturer has obtained the production license Determine whether the manufacturer has a production license by asking the dealer and checking the instructions and packaging If not, it is illegal production. Its product quality is unreliable. Don't buy it Be sure to distinguish carefully before buying

2、 Precautions for installing submersible pump

When installing the submersible pump, the cable shall be overhead and the power line shall not be too long. Do not force the cable when the unit is launched, so as to avoid breaking the power line. Do not sink the submersible pump into the mud, otherwise it will cause poor heat dissipation and burn out the motor winding.

3、 Precautions for using submersible pump

1. Try to avoid starting at low voltage. The difference between the power supply voltage and the rated voltage shall not be 10%. If the voltage is too high, the motor will overheat and burn out the winding. If the voltage is too low, the motor speed will decrease. If it fails to reach 70% of the rated speed, the starting centrifugal switch will be closed, resulting in heating and even burning out the winding bank and capacitor after the starting winding is energized for a long time. The rotor pump should not switch on and off the motor frequently, because the return flow will occur when the electric pump stops running. If it is started immediately, the motor load will start, resulting in excessive starting current and burning out the winding.
