Application of overload free design technology for pumps

In a typical centrifugal pump, the power always increases with the increase of flow rate, that is to say, the power curve is a curve that rises with the increase of flow rate. This brings a problem to the use of the pump: when the pump is running at the operating point, generally speaking, the power of the pump is less than the rated power of the motor. The use of this pump is; But when the pump head decreases, the flow rate will increase (as can be seen from the pump's performance curve), and the power will also increase accordingly.
