[0040] Specifically, when the pressure of municipal pipe network can meet the user demand, the equipment directly supplies water through valve, the pressure sensor monitors the pipe network pressure in real time, and the microcomputer control unit automatically adjusts the running state of the water pump 13 according to the preset parameters. During the peak period of water consumption, once the pressure of the municipal pipe network decreases, the pressure sensor will send a signal, and the microcomputer will start the water pump 13 and adjust its speed to meet the demand. At the same time, the energy storage releases the stored energy to supplement the water demand of the user pipe 14.
