WFY no negative pressure water-supply equipment

Our company's WFY laminated water supply has changed the traditional water supply method of pools, and has undertaken the municipal pressure to the greatest extent. The equipment is simple and practical, safe and reliable, and saves money and energy. When the water supply network is cut off, causing the liquid level to drop continuously during the steady flow compensation period, the liquid level detector will feed back the signal to the frequency conversion control cabinet, and the pump will automatically stop to protect the pump unit.
On the basis of ordinary non-negative pressure stacked water supply equipment, a backflow preventer is equipped with a partition function to solve the problem of backwater, but the resistance loss of the backflow preventer is more than 7m, so the available water head of the pipe network is very limited. Our company's WFY (I) micro-resistance anti-backflow non-negative pressure stacking equipment overcomes the defects of excessive pressure loss and insignificant energy-saving effect after ordinary non-negative pressure plus backflow preventer, and can maximize the use of municipal water supply It is an ideal secondary pressurized water supply equipment at present.
The resistance loss of our WFD micro-resistance anti-backflow non-negative pressure stacked water supply equipment is below 3m, and its energy-saving effect can be increased by 10-30% after testing. Complete functions, with no negative pressure, superposition, as well as micro-resistance, anti-backflow functions, integrated in the steady flow compensator. It has auxiliary functions such as overpressure relief and air filtration.
Bangpu WFY (II) non-negative pressure superimposed water supply equipment: On the basis of the general non-negative pressure completely relying on the vacuum suppressor to avoid vacuum generation, a flow controller is added to ensure that the municipal pressure is at a certain limit value and does not pump Suction municipal pressure without causing pressure reduction in other water areas. A pressure tank is added to the steady flow compensator to avoid sudden surge of pressure at the front end of the equipment during sudden peak water consumption. Liquid level detection includes avoidance of water shock. With water intake, sampling for water quality monitoring; with overpressure protection; containers with sewage outlet.
Bangpu WFY (Ⅲ) non-negative pressure stacked water supply equipment: fully enclosed water supply, using stainless steel flow parts and silicone seals to ensure fresh and pure water quality, in line with national drinking water product hygiene standards. The conventional backflow preventer and flow controller and other components that are isolated from the municipal pipe network are all at the front end of the equipment. The anti-backflow design produced by Bangpu has changed the concept, so that the WFY lamination equipment can guarantee: when the pump is one-way after the pump When the valve is not working, the backflow preventer can be used to prevent the hydraulic backflow to the municipal pipe network, and it is ensured that the steady flow compensator can only withstand the pressure of tap water, which improves the service life. The first-level one-way valve leakage protection function is added to prevent the circulation of pressure water in the pipeline and avoid the damage of the water pump. When the municipal pressure is good or bad, and the bypass valve is set, the regular inspection function will be provided to prevent the long-term standby water pump of the unit from rusting.
