Water supply system doesn’t fix a certain pump as variable-frequency pump, when system pressure is
insufficient, the running variable-frequency pump firstly switch to grid-power frequency running, and
then variable-frequency enable the next new pump, the pump is the new variable-frequency pump.
When the system has too much pressure, power-frequency pump stops. The same moment at most
only one pump work as variable-frequency pump, another one work on power-frequency, (can control
