The Birth Of Non-negative Pressure Water Supply Equipment
Feb 10, 2018

As early as the 1940s, no negative pressure water supply equipment has not been born, as people's demand for water, the concept of no negative pressure to appear slowly. However, due to the backwardness of technology, the simple way of water supply can only meet the basic needs of the daily, so our country scientists in the way of water supply and other series of problems on the road to continue for many years.

In the the 1980s, Japan has begun research on this subject, not only on the technical level, but also on the market demand, administration and law, urban high-rise building water supply model and other aspects of the discussion also began. The direct water supply system is included in the National Policy guideline document "The long-term goal of the water supply system transformation and re construction for the 2l century", and the corresponding revision is made to the water supply design specification, The Water supply network Terminal Service pressure from the original 0.15Mpa to 0.2MPa, by the state to provide the corresponding funds in Qianye County built with a certain scale of the laboratory, and organized a group of scientific research institutions, water supply enterprises, scholars and product manufacturers constitute a team, in the funds prepared, On the "direct water supply" aspects of the study, planning to use 3 years of time to "promote the direct water supply system," the completion of the study, did a lot of corresponding research. Since 1992, the Sapporo Waterway Bureau of Japan has introduced a new two water supply plan, and only 68 buildings in that year have been supplied with laminated water supply equipment, the original water tank has been cancelled and the improvement effect has been evaluated well. Dareyet Water Group, a specialized water company in the United States, has been working on the development of two new technologies for water supply, and has successfully promoted the use of laminated water supply series equipment in the United States and around the world. By the late 1990s, the water supply technology of pipe network has been widely used in Japan, America and western Europe.

In the 90 's, because the city's water supply capacity is seriously inadequate, can not reach the user's water level or flow, a special research and development of new environmental protection and energy-saving professional equipment-no negative pressure water supply equipment emerged.

With the rapid development of science and technology, no negative pressure water supply equipment directly connected with municipal water supply pipe network, in the municipal network residual pressure on the basis of series of laminated water supply, make full use of the original water pressure, the difference of how much to fill, high efficiency and energy saving. Replaced the previous "Storage tank + water Pump + high water tank" two times pressurized water supply mode. At the same time, greatly reducing the cost of residents.
