Deep Well Submersible Pump Start - up and Precautions for Use

Our main products: QS, 175QJ, 200QJ, 250QJ, 300QJ series, QJR series hot water deep well pump, QSP series fountain pump, WQ series submersible sewage pump, From 0.75KW to 220KW. Because of its excellent quality, energy efficient, safe, reliable, reasonable price, favored by the users
When purchasing deep well submersible pump:
1, should pay attention to its model, flow and head. Such as the selection of inappropriate specifications, will not be able to get enough water, can not cast the effectiveness of the unit. In addition, should also find out the direction of rotation of the motor, some types of submersible pumps are forward and reverse when Jieke water, but reverse the water volume is small, the current is large, the reverse will damage the motor windings. In order to avoid leakage when the submersible pump in the water caused by electric shock incident should be installed leakage maintenance switch.
2, the device, the cable to overhead, the power cord should not be too long. Do not force the unit into the water, so as not to cause the power cord breakage. Do not sink submerged in the mud, otherwise it will lead to poor heat and burn the motor winding.
3, try to prevent the boot in low voltage. If the voltage is too high, it will cause the motor to overheat and burn out the winding. If the voltage is too low, the motor speed will fall. If it does not reach 70% of the rated speed, the centrifugal switch will be closed and the start winding will be closed. Prolonged power and fever and even burn the winding and capacitors. Do not frequently switch the motor, this is because the pump will produce a return flow stalled, if the immediate start, the motor load will start, resulting in too large starting current and burn out the winding.
4, do not let the pump long-term overload operation, do not smoke a large amount of sediment water, dehydration pump running time should not be too long, so that the motor overheating and destruction. In the homework, the operator must at any time to see its working voltage and current in the nameplate on the value of the delineation, if not the motor should end the run, find out the cause and eliminate the fault.
5, usually more than review the motor, such as the invention under the cracks, rubber seal ring damage or take effect, should be replaced or repaired in order to prevent water penetration machine.
