Energy-saving water supply system facilitating pressure stabilization and pressure superposition of municipal water supply pipe network
The invention discloses an energy-saving water supply system facilitating pressure stabilization and pressure superposition of a municipal water supply pipe network. The energy-saving water supply system facilitating pressure stabilization and pressure superposition of the municipal water supply pipe network comprises an energy-saving pump assembly, a pool device, a first one-way valve, a butterfly valve, an electric valve and a control assembly. The municipal tap water pipe network is connected with the water inlet end of the pool device and the input end of the first one-way valve through the butterfly valve, and the output end of the first one-way valve is connected with the input end of the energy-saving pump assembly. Double-pipe control over municipal tap water pipe network water supply and pool water supply is directly performed through a frequency converter with a PLC function; when the pressure of the municipal water pipe network is smaller than a certain pressure value, the system can automatically switch current water supply to pool water supply, water is pressurized through the pool to be supplied to users, and therefore normal water supply is guaranteed; if the system monitors that the pressure of the municipal pipe network is larger than a certain pressure value, the system switches current water supply to municipal water supply again. In this way, electricity saving efficiency is improved, and pressure stability of the municipal pipe network is guaranteed.
