ZHONGYING Tall water supply equipment is how to achieve the ultimate energy-saving emission reduction

Summary of high-rise water supply equipment:
In order to solve the traditional living water supply system, the problem of negative pressure and pump two water supply equipment in the process of direct access to tap water pipeline network, my unit innovation has developed a new generation of "win in building water supply equipment". This product not only solves the problem of pollution two underground pool, also can be matched with pure water equipment, direct drinking water equipment as a booster, can be used in any a pressurized pipe network in water supply system.
Principle of high rise water supply equipment:
1, the microcomputer set to pump working pressure, that is, user water pressure. When the water supply is in operation, the equipment is operated in the state of low voltage frequency conversion, and the pressure of the pipe network is monitored by the frequency converter. If the pressure of the pipe network is higher than the pressure required by the user (setting pressure), the output frequency can be reduced automatically. If the pipeline pressure below the user required pressure (set pressure) will automatically increase the output frequency, so that the pump speed is increased, the content increased, when a water pump operation can not meet the needs of users, the other pump automatically put into operation to ensure that users use pressure.
2, when the tap water pipe network pressure reaches to the user when the pressure transducer, after a long time will reduce the speed until the shutdown, only when the pressure down to a set pressure value, the inverter can start work again. The work of the frequency conversion pump group only satisfies the difference between the water pressure of the user and the pressure of the pipe network.
3, when the flow regulator pressure below atmospheric pressure, the installation of automatic flow control in the open top of the vacuum suppressor, the gas enters the gas flow control, eliminate the negative pressure. When the pressure of the flow regulator is increased, the excess gas can be discharged out of the flow regulator, so that the flow regulator is filled with water to prepare for the next water peak. When the flow regulator is filled with water after the installation of automatic flow control in the closed negative pressure suppressor top, to prevent overflow.
Performance index of high rise water supply equipment:
"Win the high-rise building water supply equipment" is a new type of water supply equipment developed by Changsha Zhong win water supply equipment Co., ltd.. With the constant pressure water supply pressure variable, obvious characteristics of high precision, the premise that at constant pressure, flow rate from zero to maximum flow range, water pressure changes in the range of - 0.01Mpa within, can eliminate the negative pressure phenomenon of tap water pipe network, improve the reliability of water supply system; small footprint, saving construction investment installation, convenient use and maintenance; is suitable for the ideal water supply equipment in industrial and civil building life system.
"Win the high-rise water supply equipment," the main indicators are as follows:
Flow range: 2.4m3/h-300m3/h;
Pressure range: 0-1.6MPa, adjustable;
Speed range; 0-1450r/min or 0-2950r/min, adjustable.
Characteristics of high-rise water supply equipment:
1, energy saving:
Building water supply equipment using frequency conversion technology to pump soft start equipment to avoid the current impact to the power supply; at the same time for constant pressure control, also to avoid the impact of the network, prolong the life of the pipeline and the valve. The traditional two pressure water supply mode of the pool puts the tap water into the pool, so that the original tap water pressure is released to zero. The utility model can make full use of the pressure energy of the pipe network, and the power saving can reach 50%-90%.
2, eliminate the underground pool of the two pollution:
The traditional pool two pressurized water supply will tap water into the tank, the tank water is contaminated by dirt or animal body, especially in the summer easy to produce algae or mosquitoes directly affect the health. The equipment adopts the closed water supply mode, which eliminates the two pollution.
3, save water, reduce the risk of accidents:
Because the water supply equipment of the high-rise building adopts a fully enclosed structure, the phenomena of seepage, running, running, dropping, leaking, etc. are avoided, and no water tank is used for cleaning and washing water.
4, the use of PID closed-loop regulation, high precision and low pressure fluctuations.
5, save investment, reduce the occupation, installation, use, maintenance convenience:
The construction of the pool (or water tank), the total investment of the project, and the use of the process should be cleaned regularly, not only increased the total investment of the project, but also increased the daily maintenance costs. The utility model uses the water supply of the regulating device to save investment and reduce the occupation area, and the utility model can be installed in a vertical or horizontal way according to the on-site situation of the user.
6, high degree of automation, reliable operation, convenient management.
7, with overload, short circuit, over current, under water, overpressure and other automatic protection function.
Application scope of high-rise water supply equipment:
1, suitable for any water supply pressure in the area of insufficient water supply;
2, the pool has been built, you can use non negative pressure direct frequency conversion water supply equipment and pool common water supply mode, further energy saving;
3, the water supply of large water supply pump station;
4, low water pressure can not meet the requirements of fire water;
5, the transformation of the original air pressure water supply equipment, can make full use of the original pressure tank;
6, the new residential areas, office buildings, residential water complex;
7, a variety of circulating water system;
8, industrial and mining enterprises production, domestic water, etc..
