A frequency converter plus a variable-frequency motor will suffice; the theoretical basis for pumps lies in three proportional laws (flow rate, head, power)
Does a low data volume result in a lower rotation speed?
The frequency conversion of a variable-frequency water pump takes place in response to fluctuations in water pressure; it consists of an inverter and a variable-frequency motor
Through an inverter-driven motor, it was previously understood that a manual method was used: different speeds were set manually, such as at startup, during steady operation, and later on, in order to adjust the pump flow rate.
Frequency conversion means changing the supply frequency in order to regulate the load. The core of frequency conversion technology is the inverter, which achieves automatic adjustment of the motor’s operating speed by changing the supply frequency.
Based on the signals from downstream feedback, the frequency is adjusted, which in turn adjusts the pump speed to achieve automatic flow regulation
