1.The selection of the pump is too large, and the flow and head are larger than the actual condition due to improper selection of the coefficient. This situation makes the pump in the operation process, cavitation phenomenon, resulting in premature damage of the pump flow parts under the combined action of cavitation and abrasion, in the case of serious cavitation, the pump will produce vibration and noise, and even lead to a sharp decline in the flow, head and efficiency of the pump can not run; In addition, the pump in the operation of large flow, will also cause motor overload, heat, serious will burn the motor.
