Non negative pressure water supply equipment saves costs and occupies a small area

Description :

Non negative pressure water supply equipment Non negative pressure water supply equipment suppresses the formation of vacuum in the pipeline network. The vacuum suppressor has the function of automatic negative pressure elimination. When the water supply of the municipal pipeline network is less than the required water output of the user, the anti negative pressure device in the equipment, vacuum suppressor pressure and flow sensor, intelligent control cabinet, water supply pipeline and control valve, etc. can be connected in series with the municipal incoming water pipeline network for pressurization without negative pressure generation. The core components of the equipment are a steady current compensator and a vacuum suppressor. The steady flow compensator is a closed machine control technology that automatically adjusts the frequency conversion speed of the water pump group or increases or decreases the number of water pumps according to the user's water consumption to achieve constant pressure water supply. Firstly, a constant working pressure is set based on the user's required water supply pressure. If the pressure value of the municipal pipeline network is lower than the user's required pressure, the supply of domestic water such as newly-built residential office buildings, booster pump stations in water plants, domestic and production water supply in industrial enterprises, and circulating water systems will be provided. The composition and principle of a non negative pressure water supply system. The non negative pressure water supply system is mainly composed of a variable frequency speed regulating water pump group and a stable flow pressure compensating pump, which has a relatively low frequency of use. Discussion on the application of non negative pressure water supply technology in the field of secondary water supply (original manuscript). Due to the fact that the variable frequency non negative pressure equipment is in a sealed state during use, it ensures the overall cleanliness of the system, and the equipment opens automatically to enter clean air, preventing negative pressure from affecting the municipal pipeline network. When the municipal water supply network returns to normal, the equipment can discharge air through the anti negative pressure device and automatically shut down. The steady flow compensator works under positive pressure and the equipment operates normally. The non negative pressure water supply technology is composed of flow sensors, intelligent control cabinets, water supply pipelines, and control valves. This system can be connected in series with the municipal water supply network for pressurization without generating negative pressure. The core component of the device is steady current.
