Product Description
The variable frequency pump control cabinet system adjusts the output frequency through the PID controller built into the frequency converter system based on the detected pipeline pressure, thereby achieving constant pressure water supply in the pipe network. The frequency converter's frequency limit signal (generally used as the pipe network pressure limit signal) can notify the PLC in a timely manner for variable frequency pump switching. To prevent water hammer phenomena, the pump's switching will be interlocked with its outlet valve.
