ZKWF non-negative pressure water supply equipment produced by Hunan Zhikang Environmental Protection and Energy Saving Technology Co., Ltd. can directly introduce water from urban water supply network into high-rise residential buildings. In the middle process, there is no need for a low-level water tank and a high-level water tank, that is, pure water can be directly brought into the house. Hunan Zhikang Changsha automatic stainless steel non-negative pressure water supply equipment, if used in conjunction with the fire-fighting air pressure tank, will gradually cancel the low-level pool and the high-level water tank on the premise of meeting the fire-fighting regulations, which not only saves the cleaning and disinfection costs, but also saves electricity and water. The whole set of water supply equipment is made of stainless steel, which is non-toxic, harmless, rust-free, clean and hygienic, with low noise, which is conducive to improving the surrounding environment and is an environmental protection and energy-saving product. The operation of water supply equipment is monitored and automatically controlled by computer, which has many control functions, such as pump cycle frequency conversion, soft start power frequency, constant pressure variable water supply, rapid negative pressure relief, pipe network protection, fault alarm, communication and so on. The water supply equipment is stable, safe and reliable, without personnel on duty, and has the characteristics of simple operation, convenient maintenance and low operating cost. Due to the adoption of advanced anti-negative pressure control technology, it will not have any negative impact on the water supply network under any circumstances, and it can also ensure continuous normal water supply.

Automatic stainless steel non-negative pressure water supply equipment is the latest product developed by Changsha Water Supply Equipment Company. It is a fully automatic superimposed steady-flow water supply system composed of advanced microprocessor control technology, frequency conversion speed regulation technology and steady-flow anti-negative pressure technology, which is widely used for pollution-free secondary water supply in high-rise buildings. Traditional secondary water supply methods for high-rise buildings usually adopt low-level water tanks, high-level water tanks and pneumatic tanks. Because water tanks and tanks are easily polluted by water, long-term drinking will affect people's health. Therefore, the most effective way to improve the water supply quality of high-rise residential buildings, improve the sanitary standard of high-rise residential buildings and fundamentally eliminate the "secondary water pollution" is to cancel the low-level water tank and the high-level water tank. Using pollution-free laminated steady-flow water supply equipment, tap water is directly introduced into households, which is a popular "water purification project" in Europe and America, so that residents of high-rise residential buildings can directly drink clean tap water. Zhikang automatic water supply equipment is a complete set of secondary water supply equipment, which can be directly connected with the water supply network without any negative impact on the water supply network. It can replace low-level pools and high-level water tanks, make full use of the pressure of tap water pipe network to directly supply water, avoid "secondary water pollution", ensure the water quality to meet the national drinking water standards, save construction investment, electricity and water charges, and reduce operation and management costs.
