Changsha, Hunan win to become the second largest supplier of secondary water supply system Introduction: secondary water supply system is a network of direct tandem device used pressurized water pump water supply. In urban public pipe-line directly mounted pump pumping the water supply system has been restricted. The reasons: The first is insufficient supply pipe network capacity, excess water will make the individual network nodes or pipe pressure drop and affect other users of water stability. In addition, allowing users to freely mounted pump "network" may bring security and water pipe network security risks. Secondary water supply system has been officially into the market a few years time. As the pipe network approach has the advantage of direct boost energy, water, province, provincial timber, especially because of the reduction or eradication of secondary pollution of water, health and safety protection of water quality characteristics, and the user's attention by the industry and the market ﹑ Welcome, thus promoting the progress and development of the technology. You can believe the technology has been developed to have a convincing theory and practice of probative force of more mature stage. Already qualified in the larger scope of the trial and to promote the use. Promotion of "direct supply" Technology and Applications "no negative pressure water supply equipment," the main pipe network should be a party, namely the urban water supply system. Thus, the pipe network with the condition that the prospective application of technological achievements breadth and depth of the decisive factors. And how to combine the specific situation of their own cities and water supply systems, to develop a rational, standardized, easy to operate, "mutatis mutandis conditions" should further study. Secondary water supply system without the construction of pools, water tanks, occupies a relatively small space, saving the initial investment in equipment and save the rinse sink, sink to eliminate costs. Negative pressure water equipment is fully enclosed structure, virtually eliminates secondary pollution of water supply equipment for the new green. Currently universal constant pressure water supply, cancel ground pool, reduce the secondary pollution of water, but the construction and use of underground tank costs and underground pools of water pollution is a problem. Therefore, no negative pressure water equipment will be the development and extension of constant pressure water supply equipment. Eight advantages of secondary water system products: (1) energy efficient: full use of municipal water pressure heat much difference how much, effectively, maximize the energy saving effect of frequency control. (2) Clean and hygienic: form a continuous sealed pressurized water supply, fully maintained state water quality health standards for municipal water, avoid the water quality standards due to the pressurization system to reduce water pollution and various fundamental issues. (3) eliminate waste: not only eliminated the high water tank, but also completely abolished the ground (underground) tank pool, completely eliminated the tank overflow, regular cleaning of waste water caused. (4) low noise operation: products with full frequency adjustment programs, most of the time, especially at night in a low-noise operating conditions. (5) design a fully enclosed, both cushioning effect and dynamic compensation of the water tank tank, compared with the current market so-called non-vacuum tank, more practical significance, and control system can be simplified. (6) The series control system design and manufacturing experience to fully summarizes the Company and its domestic and conversion water supply equipment, the use of standardized universal control system technology solutions, can be changed by any vendor, inverter, controller, PLC and other components debugging maintenance is particularly convenient for the product life-long service and laid a good foundation, not because of technological advances lead to service problems. (7) The series control system has a higher intelligence, designed to take full account of the mechanical, electrical, instrument coordination, with haste, less speed detection monitoring and easy interactive features. With full fault protection and countermeasures, inverter fault protection, automatic downgrade run (become Frequency automatic water supply equipment), automatic system failure, also manually operated emergency backup and win time to repair. (8) upon request matching a variety of communication interfaces, protocols, which can be connected to a variety of man-machine interface, control computer, connecting with a variety of control networks, communication networks, for special and complex operation control and network monitoring Claim. For users to develop monitoring software package. Secondary water supply system on the basis of merit adds the following advantages: the use of advanced human-machine interface control system in the world, the configuration is accurate, clear, real-time display and clear the water pressure, water pressure, set pressure, the pump current, frequency and other operating parameters and operating status can be displayed simultaneously dynamic images and real-time image. Automatic intelligent control and management, friendly man-machine dialogue, simple, reliable operation. Using remote monitoring technology for remote monitoring equipment, surveillance, monitoring, so that has a double protective equipment reliability. Users enough peace of mind. Sharing partial pressure function, for different times of day to meet the needs of different water, different pressure control can be implemented on the water peak, low hours. Per day can be set to eight different time periods, each time period can be set different pressure. Fuzzy control theory, without having to adjust the automatic optimization of the controller parameters, and provides the user changes the cut pump conditions experienced users convenience, fast response, high accuracy, when the pump is switched network impact is small. SMS queries, queries via SMS equipment operating status, fault alarm is received, not only enables us to keep abreast of the equipment is faulty, but also so that anyone anywhere via SMS query the device running. This feature allows users to stay at home to check equipment operation status, fault information is received, the equipment is not affected by the query time and place. At the same time you can add, delete, modify groups receive text messages, and can be mass text messages, so equipment problems quickly get immediate treatment. Works secondary water system products: The device uses computer inverter technology, vacuum processing technology to achieve negative pressure water, through the touch screen display operating status by vacuum compensation system and a fully enclosed structure to achieve a directly connected in series with the water pipe network and overcome the adverse effects on the pipe network. Through computer testing pipeline pressure, with negative feedback to adjust the frequency of the inverter. First set according to the actual situation of water pressure point work, testing the outlet pipe and the actual pressure and the set pressure, and if the actual pressure is higher than the set pressure, the lower the frequency converter, inverter frequency increases and vice versa. Industrial computer network at any time to detect pressure, calculate quickly, adjust the speed is instantaneous. So that the pipe network pressure is always maintained at the set value. Another device as shown in figure composition, fully sealed structure and negative feedback suppression system and water so that the device can be directly connected in series, due to the superposition principle of operation of the pump, so that the device can take advantage of the existing water pressure, increasing the frequency control Water saving point of the device. When the water pressure causes the pressure drop, the device steady flow of vacuum degree and level signal compensation within the vacuum regulator suppressor and compensator detection device acquisition, through computer control vacuum suppressors and steady flow compensator Special equipment movement, suppression of negative pressure to produce, to ensure that this device does not produce any negative Chengshiguanwang. Hunan has become the country's largest supplier of secondary water supply system
