Web10 de ago. de 2024 · If flow or head pressure is decreased, energy will be saved. Because the VFD exactly matches desired system design points, power consumed by the pump is minimized, improving overall pumping efficiencies. Pw = (flow x head) / 3,960 (assuming specific gravity of fluid is 1) Equation 1. WebIn this article, we explain the advantages of using a VFD to regulate pump speed, in comparison to the use of valves which have traditionally been used to throttle the flow from the pump. Why do we need to regulate the flow rate of industrial pumps? Most industrial pumps are designed to operate at peak efficiency while at their maximum flow rate. WebThe Variable Speed Controller works by varying the speed of the motor depending on the demand of the pump. It is best thought of as cruise control: if you encounter a hill, the car automatically speeds up to compensate for it. The opposite is also true, and this is exactly how a VFD Drive works. Through precise and careful engineering we are ... greater or equal to copy paste
