the second booster pump 280 is arranged on the water supply main pipe 260, and the second booster pump 280 is arranged in the middle of the water supply main pipe 260 and is matched with water supply for high-rise communities;

the second booster pump 280 is provided with a fourth accumulator 281 to collect and store surplus energy generated from the second booster pump 280.

Specifically, this energy-saving municipal water supply piping system's theory of operation: firstly, domestic water in the municipal water supply pipe 300 is introduced through the first water inlet pipe 110, the first booster pump 130 works, meanwhile, the first accumulator 140 collects and stores redundant energy generated by the first booster pump 130, after the domestic water is boosted by the first booster pump 130, a part of the domestic water flows into the water storage tank 180 through the third water inlet pipe 160, when the liquid level sensor 181 senses that the water storage tank 180 is full, a signal is sent to the second electromagnetic valve 170, the second electromagnetic valve 170 is closed, the third water inlet pipe 160 stops supplying water to the water storage tank 180, the other part of the domestic water flows into the first water outlet pipe 210 through the second water inlet pipe 150, after the variable frequency water supply mechanism 250 is regulated and controlled, the domestic water flows into the water supply main pipe 260 and then flows into the water supply branch pipe 270, after the domestic water in the lower water supply branch pipe 270 is reduced in pressure by the pressure reducing valve 290, the domestic water in the upper water supply branch pipe 270 is boosted by the second booster pump 280 and then is supplied to users, finally, when sensing that the night comes, the photosensitive sensor 240 sends a signal to the first booster pump 130 and the third electromagnetic valve 230, the first booster pump 130 is turned off, the water supply of the first water inlet pipe 110 is slowed down, the first energy accumulator 140 releases the stored energy when the flow pressure is insufficient, the third electromagnetic valve 230 is turned on, the domestic water in the water storage tank 180 flows into the first water outlet pipe 210 through the second water outlet pipe 220, and the water is supplied to the users in the residential area after being regulated and controlled by the variable frequency water supply mechanism 250.
