Equipment Advisory Dai: 13548670698 (welcome to call for inquiry ~) QQ online consultation: 1766048690 micro letter of the same phone number Address: Yuhua District, Italy all the way to the modern business center B4062 Star Factory Address: Industrial Park, Long Shali Tuo professional water equipment manufacturers , Hanson supply, of your worries - Shangqiu secondary water supply equipment manufacturers (Dai: 13548670698) no negative pressure water supply equipment, constant pressure water supply equipment, water piping pressure equipment, vacuum pipe pressurized steady flow water supply equipment, production and processing, specializing in non-vacuum, secondary pressure, constant pressure, no water tower equipment manufacturers. Shangqiu secondary water supply equipment Features: Shangqiu secondary water supply equipment, water supply high quality: the use of constant pressure pump outlet control, no matter how the water changes in the system, are to make the pipe outlet pressure constant. Shangqiu secondary water supply equipment and reliable operation: imported variable speed drives and high-quality domestic water pump, the main function with perfect protection and automatic, manual conversion main function, the operation is very reliable. Shangqiu secondary water supply equipment energy efficient: to adjust the pump speed according to user changes in water, the pump is always working in the high zone, saving effect is obvious, than the constant speed pumps can save 35%. Simple Shangqiu secondary water supply device operation: using automatic control, the operator simply convert cabinet switch, users can achieve the required conditions. Shangqiu secondary water supply equipment, small footprint device easy to install: a set of complete equipment control cabinet and one pump unit, installation is very easy. Shangqiu secondary water supply equipment to extend the life of pumps and motors: for more than one pump can achieve reliable soft-start, and take turns running, greatly extending the life of pumps and motors. Shangqiu secondary water supply equipment range of applications: for traffic from 5 to 5000 tons / hour, lift 20 to 140 meters. Shangqiu secondary water supply equipment significant economic benefits: Using Shangqiu secondary water supply equipment, not to set the roof of the tank, reducing the cost of the building, but also to overcome fluctuations in air pressure tank, pump start and construction of towers frequent one-time sponsor large, construction long cycle cost disadvantages. Shangqiu secondary water supply equipment uses advanced technology to introduce a. High-rise buildings, residential areas, villas and other household water. b. Daily water enterprises, hotels, office buildings, department stores, large sauna, hospitals, schools, sports centers, golf courses, airports and other places. c. Manufacturing, washing equipment, food industry, factories, industrial and mining production water. d. Other old pond water and other forms of reconstruction of water supply. It is a secondary pressurized water supply equipment directly connected to the municipal water pipe network. Equipment by the water pressure sensors, pressure sensor outlet of the pump, pressure pump, frequency control cabinet and other accessories of pipeline. Especially suitable for single buildings or other smaller occasions pressurized water flow. Shangqiu secondary water supply equipment Features: 1, the device is in series with the water pipe network directly at the sealed flow regulating device and the negative pressure fire device, so that the water pipe network does not produce negative pressure, does not affect the surrounding water users, so that " secondary water supply facilities shall not be directly connected to the city water supply network in urban water supply pipe line shall be mounted directly on the pump pumping "of the past. 2, to prevent secondary pollution major aspects of secondary pollution of the secondary pressure system, especially contaminated pools, water tanks more prominent, run for the entire seal. You do not need pools, water tanks, eliminating the major aspects of secondary pollution. Thoroughly to ensure that the water quality. Now, Shangqiu secondary water supply facilities in the outlet pipe usually has pressure tank, the volume of different sizes. Water supply equipment, it is the direct supply of equipment water points, none of which have been in the water conditioning equipment, day and night, large water changes, in the evening a small flow, often with low flow pump and pressure tank to maintain the system pressure and a small amount of water. Then large pump dormancy, a small pump from the electrical contacts pressure tank water supply system control, intermittent operation to save energy. Providing such a pressure tank water changes in the larger system is absolutely necessary. Now, some set up a very small pressure tank at constant pressure outlet pipe layers of water supply frequency unit, I believe that this pressure tank only play the role of water hammer eliminator, there is no regulation of the flow rate, so the pressure the higher it is necessary to lower pressure equipment is not so necessary. Therefore, whether to set pressure tank can not be generalized, the system should be based on the desired function to determine the set or not set pressure tank, which set the pressure tank. In short, the construction of a new water supply field equipment, application time is not long, there are many issues to be further research and improvement, willing to our joint efforts in the implementation of the road "four a green" policies Shangqiu achieve good results on the secondary water supply equipment PID control principle: according to the feedback principle: in order to maintain a physical constant or substantially constant, it should lead to this relatively constant physical and form a closed loop system. We want to maintain a constant pressure, so it is necessary to introduce pressure feedback value and given value, thereby forming a closed-loop system. However, the system being controlled product characteristics are nonlinear, large inertia of the system, now control and PID a combination of methods, pressure fluctuations in the use of fuzzy control, in order to speed up response time; smaller when using PID in the pressure range to remain static precision . This is done by adding PLC intelligent instrument time is now the algorithm can be switched simultaneously to PLC programming time is now pump frequency and frequency between. Practice has proved that this method is feasible, and cost is not high. In order to maintain constant pressure water supply network, according to the feedback theorem on the management network system equipment installed pressure transducer as feedback element, since the water supply system pipe length, diameter large, pressurized pipe network is slow, Therefore, the system is a big delay system, easy to direct the use of PID regulator control, and participation by way of PLC controlled to achieve the control system regulates use. Green energy saving and environmental protection industry is the backbone, Changsha rise only to "green environmental protection, innovation and advanced," the idea for the product development of water supply facilities, and lean design and excellent technical services also support from the booming industry of environmental protection equipment "green development" of a clear sky. Secondary water supply in urban construction indispensable part, but a big problem caused by secondary water quality problem can not be ignored, and find a secondary reason for water pollution, water supply equipment from the design and construction of continuous improvement, is to ensure the quality of water The major source.
