Full-automatic stainless steel non-negative pressure water supply equipment is the latest product developed by Changsha Water Supply Equipment Company, which is a full-automatic superimposed steady flow water supply system composed of advanced microprocessor control technology, variable frequency speed control technology and anti-negative pressure stabilizing technology, and it is widely used for non-polluting secondary water supply of high-rise buildings. The traditional secondary water supply for high-rise buildings, usually using a low pool, high water tanks and pneumatic tanks for water supply, due to pools and tanks are easy to "water secondary pollution", long-term drinking will affect people's health, and thus improve the quality of water supply for high-rise residential, enhance the health standards of high-rise residential, and fundamentally eliminate the "water secondary pollution", and thus improve the quality of water supply for high-rise housing, enhance the health standards of high-rise housing, and fundamentally eliminate the "water secondary pollution". The most effective way to eliminate "secondary water pollution" is to cancel the low-level pool and high level water tank. The use of non-polluting pressure stacked steady flow water supply equipment, tap water is introduced directly into the household, that is, Europe and the United States popular "water purification into the household project", so that high-rise residential residents directly drink clean tap water. Zhikang automatic water supply equipment is a kind of secondary water supply equipment that can be directly connected to the water pipe network and will not have any negative effect on the water pipe network. It can replace the low pool and high water tank, can make full use of the pressure of the tap water network direct water supply, to avoid the "water secondary pollution", to ensure that the water quality in line with national standards for drinking water, and at the same time to save investment in construction, power saving, water saving, reduce operating and management costs.
