High-rise building water supply systems, you understand the principles of high-rise building water supply system it? Learn it together Wang Shi North Zhongyuan date not been forgotten .-- Lu, Everyone must die, to retain loyalty according to annals .-- Wen Tianxiang rise building water supply system works: high-rise building water supply system works by automatically adjusting the number of units to run the pump and a water pump speed changes according to the user, so that the pump outlet pressure remains constant. When the high-rise building water supply system when a user less than a water pump out the water, the control system according to changes in water has a water pump to adjust the operating frequency, when the water increases the pressure drop in the pipe system, when the pressure sensor to detect the signal transmitted to the computer control unit, run by computer to determine, issue commands to the inverter to control the pump motor, the speed is accelerated to ensure that the system pressure constant, whereas when the water was reduced, so that the pump speed slows down to maintain constant pressure. When the water is greater than a water pump, the first pump is switched to frequency operation, the second pump start frequency adjustment operation, when the water is greater than two pumps out water, it will automatically stop one or two sets of pump operation . Throughout the operation, the high-rise building water supply system remains constant pressure system, the pump is always working in the high zone, both to ensure constant water supply users, but also saves energy. How much water users is constantly changing, so the water supply shortage or excess supply situation have occurred. The imbalance between the supply of water and concentrated reflection on the water pressure, water that is more and less water, the pressure is low; less water and more water, the pressure. Maintain a constant water pressure, can maintain a balance between water supply and water, too much water that the water for a long time, the water supply came from less, thereby improving the quality of water supply. With the power of technology, inverter technology is improving daily, with frequency control as the core of intelligent water control system to replace the previous high water tank and pressure tank and other water equipment, a smooth start, starting current limit within the rated current, thus avoiding the impact on the grid at the start; the average pump speed is reduced, and thus extend the life of pumps and valves, and other things; you can eliminate water hammer effect starting and stopping. Its stable and secure operating performance, simple and convenient operation, as well as a full array of capabilities will enable to achieve water-saving, energy-saving, labor-saving, and ultimately achieve the purpose of high-efficiency operation. High-rise building water supply system features energy efficient: high-rise buildings to pump water supply system for export control variables constant, further extends the speed range of the pump, saving up to 50%, water pressure constant, set up its regulation accuracy down 0.01MP value less leaky system, can be saving 10%. As a result of the pump outlet pressure control system in any water changes, it can make the service of constant pressure water supply network to ensure the quality of water supply. Automated processes, high-rise building water supply system long operating life, the whole machine work using intelligent CNC automatic frequency control, easy to operate, controlled by the computer program. The unit can perform soft-start, no impact on the electrical and mechanical, electrical equipment and greatly extend the life of machinery. Fully functional, can be added a variety of additional features, such as small traffic stop, a small flow switch, pools dry down, when the pool water, automatic boot. City Network pressure rises automatically shut down in hibernation to meet water consumption. But there is a certain pressure pipe network but low, while not reach the highest level, automatic re-start the pump running. Timing start, stop, timed switching. Water supply equipment and the other with frequency automatic and manual operation and running a variety of ways. In any case, constant pressure water supply system can reliably put into operation to ensure continuous water supply system.

Small size, light weight, low construction costs; easy installation, short construction period, short duration, low noise, there are secondary pollution. Can maintain a high degree of natural water during power outages. High-rise building water supply systems Product Overview Over the years, the town municipal water supply pipe network pressure to meet the ordinary low-rise buildings are set in their water supply water pressure, so that the majority of buildings are urban secondary pressurized water supply must meet the building water demand. China's urban secondary pressurized water supply has gone from "reservoir + booster pump + water tower water supply", "reservoir + + high pressure pump tank water supply", "reservoir + booster pump + pressure Tank water supply "and" cisterns or storage tanks + frequency control unit pressurized water supply, "four stages of development, has entered the" no negative pressure water pipe network overlying water supply pressurized crew "new era. Currently, in the field of domestic secondary water towns, in addition to the "reservoir + booster pump + water tower water supply" to basically disappeared, the other three second pressurized water supply have to use, but with "reservoir or storage + Frequency pressurized tank unit water supply, "which, while no negative pressure water pipe network layers ways is just beginning, is gradually replacing other water ways and become urban secondary pressurized water system mainstream. In addition to "negative pressure water pipe network layers mode", the other four water supply have a common feature, that is, the second pressurized water supply system have cisterns or storage tanks. For ease of description, the content will be collectively referred to herein below its reservoir water supply. In this type of water supply, at work and the first municipal water pipe network pressurized vent into the pool, and then pressurized by pumping pressurized equipment into the water supply network from the pool. Although the above water supply to meet the demand of water pressure, but there are sources of secondary pollution and energy waste problem difficult to solve. With the development of society, energy supply has become tighter, build energy-saving society are growing; on the other hand, continued to improve living standards for drinking water quality requirements is also rising; in addition, water shortages have been a threat to urban residents The problem of drinking water, water prices continue to increase; urban construction land with growing tension rising land prices. Because of these reasons and their own lack of existing water supply, water supply problems in the current increasingly prominent, has been unable to meet the needs of social life. Community energy, water, health, safety, pollution-free new water supply demands more urgent. In this context, negative pressure water pipe network layers came into being. High-rise building water supply system selection Description Selection JBW rise building water supply systems is determined according to the user of water pipelines, pressure and flow rate, the actual amount of water users, such as building height data, the device table with the regulator in accordance with the volume of water Under flow to meet the requirements of the case estimates, if the water pipe is very small, the water flow can not meet the water requirements of the peak period, the volume of the need to recalculate the regulator recommended the following formula: V Volume = (Q -Q carry out) △ t Q = the day into the highest peak of the water out of the water into the water Q = highest water peak day water users t = duration of maximum water level peak of construction of water supply systems products Eight advantages (1) energy efficient: full use of municipal water heat stress, how much make up the difference, effectively, maximize the energy saving effect of frequency control.
