Negative pressure water supply system advantages

(1) Advanced and reliable water supply method

Traditional secondary pressurized water supply method needs to be set up in the pool or tank, there is a large footprint, easy to produce water contamination, construction time is long, routine maintenance and management trouble, and can not be directly connected to the municipal water network or other pressurized pipeline network pressure, the system has high energy consumption, high pump head, operation noise and other shortcomings. Negative pressure water supply equipment and municipal water supply network or other pressurized pipe network directly connected to the pressurized, in the system does not need to set up pools or tanks, and the system is fully closed structure operation, completely eliminating water contamination, and can make full use of the original inlet pipe network pressure, energy-saving system operation. Negative pressure water supply equipment and the traditional secondary pressurization equipment, compared with a small footprint, flexible installation, energy-saving operation, and water quality safety, health, environmental protection, no pools, tanks, "running, bubbling, dripping, leakage, seepage," as well as regular cleaning and disinfection of the waste of water, is in line with the national "material, land, water, energy saving, environmental protection, and the" material, land, water, energy saving, environmental protection. It is a kind of safety product in line with the national "material saving, land saving, water saving, energy saving and environmental protection" of "four sections and one environmental protection", and it also has the advantages of advanced technology, reliable operation, excellent performance, economical and practical, easy installation and maintenance, and so on.

(2) Eliminate water pollution

The real no-negative-pressure water supply equipment adopts the fully enclosed self-balancing structure, 100% isolation from the air during operation, and no other external dirt into the water, the equipment over the water part of the use of stainless steel, copper, etc. in line with drinking water hygiene norms of the material made of food-grade anticorrosive coatings lining, will not breed algae, water supply water hygiene without any water quality pollution. Any water pollution.

(3) energy saving

Traditional secondary pressurized water supply needs to be municipal tap water into the pool or tank storage, the original pressure of tap water all released to zero and can not be utilized, the equipment will cause a huge waste of energy for long-term operation. If a water supply of 5 × 103m3 / d of the intermediate pressurized pumping station, can be used to tap water inlet pressure according to the municipal general pressure of 0.20MPa considerations, then the use of negative pressure water supply equipment each year on the use of tap water inlet pressure can be saved 13 × 104 degrees of electricity, energy saving of 50% -90%.

(4) save investment

Non-negative pressure water supply equipment can be connected to the pipeline network water supply pressure is insufficient to carry out direct pressurized water supply, without the need to set up a pool, tanks or water towers, etc., eliminating the need for water disinfection equipment, saving investment. Only pools, tanks or water tower construction costs can save a one-time investment of less than tens of thousands, more than 100,000, hundreds of thousands; at the same time, no negative pressure water supply equipment can be utilized inlet network pressure, pumps supporting low head, small power, and accordingly reduce the purchase cost of the equipment; in addition to the small size of the equipment, the compact layout also saves the investment in pumping stations and occupies an area.

(5) save space

The use of negative pressure water supply equipment without the need to set up pools, water tanks or water towers, etc., and equipment structure is compact, saving the footprint, which is like gold for the modern urban buildings, is undoubtedly a great asset, especially the integrated negative pressure water supply equipment basically does not take up space, the advantages of which are even more obvious.

(6) saving water

No pools, water tanks or water towers, "running, bubbling, dripping, leaking, seepage" and regular cleaning and disinfection, etc., can save a lot of water waste costs. For example, a comprehensive building complex, the daily water supply of 1200 tons, according to the traditional pressurized way need to set up a volume of 300 m3 of underground living pools, pools need to be cleaned 2 times a year, due to the loss of water caused by pools (pools of overflow, leakage, evaporation, etc. caused by the waste of water) to reach the daily water supply of 2%, the annual waste of water caused by pools of more than 9,000 tons, the equivalent of Annual economic loss of 20,000 yuan. For the entire town of the second pressurized water supply field, caused by the waste of water is even more difficult to count. Therefore, the use of non-negative pressure water supply equipment compared to the traditional secondary pressurized water supply can better save water and reduce operating costs.
