This system uses PLC and inverter control pump working pressure, according to the given ideal value signal and pressure of the pipe network pares the feedback signal, frequency converter according to the pared result, adjust the pump speed, to control the pressure of the pipe network for the purpose of. This paper mainly describes the energy saving principle of variable frequency, constant pressure water supply theory and PID control. And provides the control system hardware and control software, the simulation debugging success, to achieve reliable operation, energy saving, low noise, simpl
