Products: automatic negative pressure water supply equipment without negative frequency of water supply equipment selection is based on the data of the user tap water pipelines, pressure and flow, the user's actual water consumption, and the height of the building to determine, the regulator of the equipment used in the table volume is estimated under tap water flow to meet the requirements, if the water pipe exposed very fine flow can not meet the water requirements need to re-calculate the volume of the regulator, recommended the following formula: V volume = (Q out-Q into) △ t Q into = the maximum daily the water peak period tap into the water Q water consumption performance and advantages of t = maximum the water peak period duration = day maximum peak water users: Needless to build the pool or water tanks, directly connected with the water pipe network can be fully With the original pressure of tap water. 2. Pressure of tap water in the equipment directly supplied to the user, sealing, and less contaminated water, the water supply of good quality, environmentally friendly water supply equipment. Directly connected with the water pipe network, make full use of the original pressure of tap water, tap water to meet the requirements, the device stops working, the energy-saving effect is remarkable, and can reach more than 50%. Construction cycle is short, small footprint, easy installation, the total investment of the project can be reduced by 60%, the economy is good. 5. When user units blackout, the equipment can take advantage of the water pipe network pressure to maintain part of the water supply, the power outage is not without water. High degree of automation equipment with overcurrent, overheating, lack of water, lack of equal protection function, long service life Overview: Water is the source of human life, but in our country, many building tenants often difficult standby water bundle Rao. Why would this happen? With the improvement of city level in China, the city population increased dramatically, and the residential area to keep building and building increasingly high number of layers, to make the original water pipe network pressure shortfalls, many cities in the prevalence of water peak of the high-rise buildings do not increase The phenomenon of the water, resulting in a high-rise residential water difficult. The general solution is the construction of the pool or tank, secondary pressurized water through the pump. This approach has the following disadvantages: large investment projects. Build a pool, set up water tanks, large investment projects, the construction cycle is long, covers an area of. Existence of secondary pollution of water sources. Original pure tap water should be placed in the pool, and the pool is often contaminated with debris, dirt and other pollutants, the water in the summer the pool is more perishable sour, seriously affecting the lives and health of residents. To this end, many units specially fitted disinfection equipment, no doubt, but also to increase the investment in equipment and operating costs. Energy and waste tap into the pool or water tank, the water pressure becomes completely zero pressure again from scratch, so tap the energy wasted. Our company has developed a patented product SBH series of negative pressure directly connected water supply pipe network equipment products to market by public concern, and the majority of users, I introduced a new generation of non-negative pressure pipe network directly connected water supply equipment it increases the original negative pressure compensation tank volume, improve the ability to compensate for the steady flow to make the equipment more perfect and reasonable, the main advantages are as follows: Do not build a pond or tank, can take advantage of direct connection with the water pipe network, tap the original pressure. Tap water after equipment pressurized directly supplied to the user, sealing, and less contaminated water, the water supply of good quality, environmentally friendly water supply equipment. Directly connected with the water pipe network, make full use of the original pressure of tap water, tap water to meet demand, the device stops working, remarkable energy savings can reach more than 50%. Short construction period, small footprint, easy installation, the total investment of the project can be reduced by 60% or more, the economy is good. When the user units blackout, the device can make use of the water pipe network pressure to maintain part of the water supply, power outages are not without water. High degree of automation equipment, overcurrent, overheating, lack of water, lack of equal protection function, long service life.
