How do the parameters of a centrifugal pump change when its frequency drive is adjusted?
Thread Content
For example, in a centrifugal pump with variable frequency control, when the frequency is increased, how do parameters such as outlet pressure and flow rate change?:)
Flow rate is proportional to rotational speed, while head is proportional to the square of rotational speed
According to the similarity law, the relationship between rotational speed and flow rate, head, etc. is shown in the figure.
