Non negative pressure water supply equipment

Non negative pressure water supply equipment is a type of pressurized water supply unit that is directly connected to the municipal water supply network, and is connected in series with the residual pressure of the municipal water supply network to ensure that the pressure of the municipal water supply network is not less than the set protection pressure (the set pressure must be higher than the pressure demand of the direct supply area of the community, generally not less than 1.2Kg). It is a secondary pressurized water supply equipment. The core of the pipeline network pressure (no negative pressure) water supply equipment is how to prevent negative pressure from occurring during the operation of the secondary pressurized water supply system, eliminate the impact of unit operation on the municipal pipeline network, and achieve safe, reliable, stable, and water supply without affecting nearby users. There are two types: tank type and box type. The non negative pressure water supply equipment produced by Shanghai Meiyan Yi Pump Valve mainly consists of a steady flow tank, a vacuum suppressor, a variable frequency speed regulating water pump unit, a pressure sensor, a variable frequency control cabinet, a backflow preventer (optional), a disinfection device (optional), and a small flow pressure holding tank (optional). The inlet pipe from the municipal pipeline network is directly connected to the inlet of the stabilizing tank, and the outlet of the stabilizing tank is connected to the inlet pipe of the booster pump group through a disinfection device. The outlet pipe of the booster unit is connected to the user's water pipe and directly supplies water to the user's pipeline network.
