No negative pressure intelligent constant pressure water supply equipment No negative pressure pipe network water supply

Description :

　　No negative pressure intelligent constant pressure water supply equipment No negative pressure pipe network water supplyThe core is how to prevent negative pressure from being generated during the operation of the secondary pressurized water supply system, eliminate the impact of unit operation on the municipal pipeline network, and ensure that it does not affect the ancillary systems

　　Realize safe, reliable, stable, and water supply under the premise of near user water use

　　Non negative pressure water supply equipmentAlso known as pipeline stacked water supply equipment, there are mainly tank type non negative pressure water supply equipment and box type non negative pressure water supply equipment on the market.

　　The complete set of equipment consists of a steady flow tank, vacuum suppressor, variable frequency speed regulating water pump unit, pressure sensor, variable frequency control cabinet, backflow preventer (optional), disinfection device (optional), and small flow pressure maintaining tank (optional)

　　Select) and other components. 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

　　Connect with water pipes to directly supply water to the user's pipeline network

　　The working principle is that the stable flow tank type non negative pressure water supply equipment is directly connected to the municipal pipeline network, and is connected in series with stacked water supply based on the remaining pressure in the municipal pipeline network.

　　(1) Variable frequency constant pressure water supply: When the municipal pipeline supply exceeds the user's water consumption, the stable flow tank type non negative pressure water supply equipment uses variable frequency constant pressure water supply. At this time, a certain amount of pressurized water is stored in the stable flow tank.

　　(2) Eliminating negative pressure: When the user's water consumption increases, the pressure at the connection between the municipal pipeline network and the stabilizing tank decreases. When the pressure drops below the relative pressure of 0, negative pressure is formed in the stabilizing tank, and the intake valve of the vacuum suppressor is activated

　　The door opens and the atmosphere enters the steady flow tank. At this point, the steady flow tank is equivalent to an open water tank with a free liquid surface, with pressure equal to the atmosphere and negative pressure eliminated. When the water level drops to the set value, the liquid level controller will control

　　The signal is transmitted to the control system in the variable frequency control cabinet, which controls the pressurization unit to stop working and the user to stop water supply; When the user's water consumption decreases, the water level in the steady flow tank rises, and gas is discharged from the vacuum suppressor exhaust valve,

　　After the pressure returns to normal, the pressurization unit will automatically restart and resume water supply.

　　(3) Water stop and shutdown function: When the municipal pipeline network stops water supply, the booster unit will automatically stop running under the control of the liquid level controller. After the municipal pipeline network resumes water supply, it will automatically start and resume normal water supply.

　　(4) Low flow sleep function: When the user does not use water or uses very little water, the device automatically enters a sleep state (shutdown) and maintains water supply pressure. When the user resumes using water, the system automatically wakes up and resumes normal water supply.

　　(5) Continuing water supply during power outage: When the community experiences a power outage, the municipal pipeline network will continue to supply water to users in the lower area, and the water supply will not stop during the power outage. After the equipment is restored to power supply, it will automatically start and resume normal water supply.
