Overview of the negative pressure water equipment into the water with the water pipe network is directly connected to the remaining water in the water pipe network pressure-driven equipment pushed into the water, the water pressure pump equipment on the basis of residual pressure continued pressure water supply water outlet pipe network pressure to increase the pressure required to the user after; when users tap water supply pipe network is greater than the amount of inlet pressure drops, when the device is reduced to an absolute pressure of the intake pressure is less than 0 (or set of When the pipe network protection pressure), the negative pressure device to prevent and control the device automatically starts to work on the equipment running until adjusted standby equipment downtime, ensure that the inlet pressure is no longer net decrease adverse impact on the water pipe network; when When the ability to restore the water supply pipe network, network pressure inlet pressure recovery to protect the above, the device automatically starts to restore normal supply; when the water pipe network residual pressure water supply to meet user requirements, the device automatically enters sleep mode, the water pipe network directly users of water, inadequate water supply when the device automatically resume operation; when the user does not use water or water is very small, the device automatically enters sleep mode shutdown, maintained by the water side of the device is located in a small number of the flow regulator packing tank water pipe network users leaking water users holding pressure regulator can not maintain the desired pressure tank water supply network, the device automatically wake up and resume normal operation. Process equipment running full use of the remaining pressure water pipe network, not always adversely affect the water pipe network also satisfy customer needs, reduce water consumption and achieve optimal operation of water supply systems. With "water supply equipment Promotion Center," the data show that the building pressurized water supply system uses negative pressure water equipment has gone through four stages: the first stage is a "storage tank + pump + high water tank" approach, municipal runoff into the When the storage tank regulation, and then sent back by high pump pressure tank, water tank from the high to the user, the peak water reservoirs play; the second stage is a "storage tank + pump + pressure tank" approach, municipal inflow into the tanks, and then sent back by the pressure pump pressure tank, water from the pressure tank to the user, peak water reservoir regulation when played; the third stage a "tanks + constant Alashan no negative After pressure water supply system "approach, set the water pressure system, under the control of, the rotational speed and the number of pumps in operation of the water pump with the change in the amount of change, a constant, the output pressure of a certain degree of power savings on consumption. The fourth stage of pipe network layers (no vacuum) water era device is directly connected to the municipal water pipe-line, no need to repair tanks, full use of the municipal water supply network to the pressure equipment with high efficiency, environmental protection and no secondary pollution high degree of automation, easy maintenance and other features, and gradually become rational water supply of modern architecture. No negative pressure water equipment is usually what we call negative pressure water equipment, generally refers to non-negative frequency of water supply equipment, also called frequency without negative pressure water equipment. The traditional way of water supply is inseparable from the reservoir, the water reservoir supplying water pipe is generally after such pressure water into the pool becomes zero, resulting in a large amount of energy wasted. With the development of secondary water pressure technology, no negative pressure water supply equipment from the fundamental solution to these problems. According to the "water supply equipment Promotion Center," the data show that no negative pressure water equipment without the construction of towers, small investment, small footprint, the use of water, gas automatic adjustment, automatic operation and automatic energy saving and water networks, water supply even after a power outage, After several years without care commissioning. Build towers to save and invest more than 70%, compared with the construction of high water tank to save and invest 60 percent, significantly saving construction investment. Mainly used in the production and living, office water for residential and rural. Water users in 20-2000 households. Daily water supply in 20-50000m3, water height of 150 meters, the 50-story building. Negative pressure water equipment is my factory innovation developed vacuum pipe pressurized equipment. The device is fully enclosed depict direct link with the water pipe network, through the initiative of qi flow conditioner maintenance of equipment and water pipe network does not constitute a negative pressure, guarantee the water pipe network regulator (no vacuum), safe and clean to users of water, avoiding the construction of concrete cisterns or tanks located trouble. Negative pressure water equipment leverages the existing water pipe network pressure to complete based on the original pressure superimposed on the pressure to complete the number of poor, make up the number, the secondary pressure equipment selection is reduced, saving investment, together application process can be greatly saving, is currently leading the latest model of secondary water supply methods. It is the core technology promotion center] [supply equipment introduction, with the development of senior secondary water supply technology, the current water supply industry has a lot of new technologies, the following are the core of the current relatively new water technologies. One of the core technologies: Automatic intelligent automatic intelligent deployment of technology overlying laminated deployment of technology is one of proprietary core technologies without suction force the overlying water supply equipment, the system consists of database storage module, data analysis module, data acquisition module data communication module, a booster module, the deployment module, organic combination of six modules, its structure and function completely different from the natural overlying negative pressure and vacuum equipment vacuum suppressor eliminator, is merely vacuum suppressor municipal tap water pipe network steady flow and pressure compensation to deal with, we can not achieve the role borrow pipe pressure overlying the true sense, without having to deploy with pressure function, and automatic deployment of the system in addition to intelligent booster steady flow, Preload compensation processing functions, but also uses a unique process design of pressurized water pipe network deployment, you can borrow 100% of the pipe network pressure and realize the true meaning of the triple role of booster laminated casserole achieve energy saving purposes, but also has an information processing capability, these data were collected and analyzed by real-time social systems being shipped and processed and sent to the appropriate execution units. Two core technologies: the role of automatic intelligent automatic intelligent deployment of technology undervoltage undervoltage deployment system is under water pipe network pressure is insufficient, you can deploy the system (including pressure, feedback level, flow, pressure regulation, and operating status) achieve normal supply equipment, pipe network pressure to meet the water requirements of the most negative point, completely different from the natural layers of water supply equipment. Natural overlying water supply pipe network equipment in water, slightly larger than the pipe network pressure fluctuations, the device will start and stop the phenomenon occurs frequently. Not only seriously affect the user has undervoltage forecast, undervoltage less water run feature, you can always adjust the equipment operating status according to network conditions, the realization of the device due to the water in the pipe network undervoltage condition under steady water supply. The three core technologies: fully enclosed with pressure compensation closed steady flow steady flow with pressure compensation system and natural stacked form or atmospheric pressure must be balanced fundamentally different. Natural laminated through contact with the atmosphere to eliminate the negative, but this system is a fully enclosed components comply with the requirements of drinking water, drinking water not in contact with the atmosphere, without contact with any component of the gas, and strictly ensure the drinking water health and safety, while its pressure equipment itself is to ensure that under no circumstances are always under pressure to run, to eliminate the possibility of negative pressure pipe network appears fundamentally.
