Multi-stage pump with variable frequency drive
Thread Content
Does increasing the frequency conversion result in both an increase in pump flow rate and outlet pressure?
As the frequency increases, the flow rate and head increase; as the frequency decreases, the flow rate and head decrease
Frequency conversion involves changing the supply frequency in order to regulate the motor speed
It is recommended to obtain the pump’s flow curve； Under a constant power condition, head and flow rate are parabolic ； Unless the overclocking is >50Hz, it is still necessary to follow the curve
Changing the motor frequency is equivalent to changing the pump’s speed
