Relation Between Power Consumption and Head of Submersible Pump

Relation Between Power Consumption and Head of Submersible Pump
  According to the efficiency of the pump, submersible pump performance curve is a shaft power - flow curve, one is the input power - flow curve, according to the corresponding point of view of the motor input power is how much, 13kw motor input power is certainly More than 13kw, but the specific number should be, depending on how much your pump efficiency, while the motor has a maximum input power, if the big, the motor will burn. If you can tell me the pump efficiency and flow, I can do the theoretical calculations. Adjust the lift, corresponding to the measured current, power consumption even out of the flow, and head down, the current will increase, you can control the flow of the pump outlet valve. You see the pump performance curve to know it! The same pump: the higher the head, the smaller the flow, the smaller the power head is too low, the flow on the large, and that power is great, the current on the big, easy to burn the motor! Pump can not be used in high-head low lift! So the possibility of overload burning motor is very large! Your desktop diving deep well pump, 13KW? ?? Imported pumps ah! ?? Domestic can not this power oh ~ ~ (unless the manufacturer of the motor to do a special winding, made 13KW, because 15 kilowatts of waste)
