Our CRN series pumps used in the 414V 480V 60Hz 60Hz power supply, what would be the effect? Is not the head can be reduced, there is no water pump and lift what voltage relationship?
Our CRN series water pump 1, 480V 60Hz in 414V 60Hz power supply, won't have what effect, only voltage drop corresponding to the current rise. Water pump head will not decrease.2, the water pump voltage and head have no direct corresponding relationship.
This is the world's Grundfos pump, if the pump itself support work under the 414V if it didn't need to worry about traffic and Yang Cheng, if the pump does not support the long time operation of the pump must lift and flow impact, and the multi-stage pump if it is Gao Yangcheng in the use of low lift it is also easy to burn the motor,
In the case of power, W=F*S. That is, the work done per unit time pump = the gravity of the water flow * the displacement of the waterIt can be seen that:1, the power is certain, the head and the flow is inversely proportional.2, the greater the power, the greater the product of the head and flow.Therefore, when the flow is minimum, the pump head is the maximum; when the head is the minimum, the flow is the maximum.
