 High-rise building secondary water supply equipment Hunan Water Equipment Co., Ltd. 2015 Walter take you off! (Dream Phone: 17708458503 Hotline: 0731-82258987) HN Integration Design and Water Supply National Recruitment regional agents QQ: 2549380001 run high-rise building secondary water supply equipment: no negative pressure water supply equipment, how much water users are constantly changing, so There occurs when water shortage or excess supply situation. 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. Water Equipment Co., Ltd. Hunan Walter http://www.wateret.net no negative frequency of water supply equipment constant pressure water supply equipment http://www.wateret.net/proshow.asp?id=734 http: //www.wateret .net / proshow.asp? id = 735 no negative pressure water supply equipment constant pressure water supply system for certain industries or particular user is very important. For example, in some of the production process, if the water supply for any reason without water pressure is low or short, may affect product quality, the product scrap and severe damage to the equipment. Another example is when the fire broke out, if insufficient water pressure or water supply, can not rapid fire, may cause significant economic losses and casualties. Therefore, some of the water district constant pressure water supply system, with great economic and social significance. No negative pressure water supply equipment with the power of technology, inverter technology perfected to the core of the intelligent frequency control water supply 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 secondary water supply equipment in China at present an overview of energy saving hot trend, the company is in the constant pressure water supply equipment developed on the negative pressure water equipment, negative pressure water equipment full use of existing energy water pipe network, Water demand in the same situation, you can use a relatively small power pumps and control equipment, and the use of water pressure in the case of small flow of water at night without having to start direct water pump. Compared to the traditional pool of water supply equipment can save a lot of energy running costs and investment costs. Water Equipment Co., Ltd. Hunan Walter http://www.wateret.net no negative frequency of water supply equipment constant pressure water supply equipment http://www.wateret.net/proshow.asp?id=734 http: //www.wateret .net / proshow.asp? id = 735 negative pressure water equipment without the construction of pools, water tanks, occupies a relatively small space, saving the initial investment in equipment and save the rinse pool, pool disinfection 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. Pressurized water supply equipment without negative pressure pump and water pipe network is directly connected to a pump with a pressure regulator tank water storage devices, eliminating the use of vacuum to eliminate the negative pressure within the pipe network, and directly connected to full use in the water pipe network with pressure regulator tank water storage devices as pumps, vacuum to eliminate eliminate the negative pressure within the pipe network resulting in the full use of the original pressure of the water pipe network on the basis of the secondary pressurized water supply, the equipment only to achieve the purpose of increasing (and did not affect other users of the water pipe network), but also saves build pools, water tanks cast times, to ensure the quality of the network at the same time (no secondary pollution), but also make full use of the pipe network The original water pressure, the energy saving effect is extremely significant, up to 50%. Negative pressure water equipment automatic intelligent control, with a variety of protection and control functions, can achieve true unattended. High-rise building secondary water supply equipment Features digital control: internal operating procedures throughout the dominant position of the water supply system to replace the traditional relay control law, the failure rate is greatly reduced. Electrical components (AC contactor) self-sustaining function, start with a sleep longer in the frequency by an external control handover suck - off - suction pump operation to achieve the control and stop. But by all-digital software to start and stop the pump-output abort. Greatly increasing the life of electrical components and reduce the control cabinet impatient tone. One-touch regulator linkage program: unique design, users only need to set a good pressure, press the test button to complete the setting of the relevant parameters, and then hit the switch to automatic operation, the complex things to simple operation to our customers Walter Hunan Water Equipment Co. http://www.wateret.net http://www.wateret.net/proshow.asp?id=734 no negative frequency of water supply equipment constant pressure water supply equipment http://www.wateret.net/proshow.asp?id=735 rise building secondary water supply equipment, mainly technical indicators, water flow: 5-5000m3 / h 2, the water pressure range Χ: 0.1-1.5Mpa 3, power supply Power: 38V / 220V10% AC (three-phase) 4, the ambient temperature: 0 ℃ ~ + 40 ℃ 5, relative humidity: less than 90% classification rise building secondary water supply equipment 1) high-rise building secondary water supply equipment by way of sub : (1) constant pressure variable water supply system: the pump outlet pressure is always kept at a constant value, the water supply device may vary the water demand of users varies. (2) variable transformer supply system: control system pressure test points are located in the end user's water supply system, use this measurement to control the pressure of the pump running speed at which the pump outlet pressure is changed, the user is also a change in water a. 2) high-rise building secondary water supply equipment by control points: (1) Computer control type: control by the microcontroller core components. (2) PC-control: control of the core by a programmable logic controller. 3) high-rise building secondary water supply equipment divided by the number of pump units: (1) a single desktop: a pump speed control operation, another pump spare, two are used interchangeably. (2) Multiple parallel: control of a variable speed pump is running, multiple frequency operation. But also by the terms of the structure and purpose of the system, such as classification.
