Non negative pressure booster pump for high-rise buildings in Beijing

In high-rise buildings, the municipal water supply pressure can only be supplied below the 7th floor (in fact, the 7th floor is also subject to secondary pressurization), which can not reach the water supply pressure of high-rise buildings. Therefore, in order to solve the water problem of high-rise residential residents, secondary pressurized water supply has become an inevitable choice. In high-rise residential secondary pressurized water supply, non negative pressure water supply equipment is generally used, Then the advantages of non negative pressure water supply for high-rise residential buildings mainly include:
1. Save investment. The non negative pressure water supply equipment of high-rise residential buildings is directly connected in series to the self incoming water pipe network without building a pool and water tank. It occupies less land and saves more than 50% of the comprehensive capital.
2. Water saving. The fully enclosed structure prevents seepage, running, emitting, dripping and leakage. According to the investigation and calculation of 120 users in 12 regions, the comprehensive water saving can reach more than 12%.
3. Improve the quality of water supply and ensure no secondary pollution. The non negative pressure water supply equipment for high-rise residential buildings adopts a fully enclosed structure, which is directly connected in series with the pipe network, does not use the pool and water tank, and does not directly contact with the air, which completely solves the pollution problem of secondary water supply that has plagued us for many years.
4. Save management costs. The high-rise residential non negative pressure water supply equipment operates intelligently and automatically without special personnel on duty. Because there is no water tank, there is no need to clean and disinfect, and the management cost can be saved by more than 95%.
5. Extend service life. The non negative pressure water supply equipment of high-rise residence automatically adjusts and controls the constant pressure operation according to the actual situation of water pressure. One-to-one full frequency conversion control does not do useless work. It not only saves a lot of electric energy, but also has small dynamic pressure fluctuation and does not produce water hammer, which prolongs the service life of the non negative pressure water supply equipment of high-rise residence by more than five times.
6. Low noise. The fully enclosed structure design of non negative pressure water supply equipment in high-rise residence adopts full frequency conversion start stop control mode, mechatronics and low noise.
7. Power failure and continuous water supply. In case of power failure, the tap water supply for high-rise buildings will be automatically restored without negative pressure.
8. Complete protection function. The non negative pressure water supply equipment of high-rise residence has good self-protection ability, such as over-current, overload, overheating, phase failure, water shortage and automatic shutdown, which is safe and reliable.
