Box Nanyang frequency of water supply equipment frequency of water supply equipment Shangqiu Box Walter Hunan Water Equipment Co., Ltd. [China Merchants] Whether you are standing in the world which is now a place to be determined on their own strength: do not beg for love, good love was not begging come, the moment of hesitation in the other, you should turn around; do not beg fate, destiny is a good fight for their past, that place in God's design ridge, you go straight to the firm! Merchants national agency, secondary water supply equipment sailing toward the beautiful areas of the box is no negative pressure water equipment upgrades in the original constant pressure water supply equipment and no negative pressure water supply equipment developed on the basis come. It consists of a stainless steel tank, special pumps, intelligent frequency control cabinet, no negative pressure device, pressure equipment, water system and a surge tank and other components, is a computer technology, inverter technology and motor pump assembly of the new mechatronic supply equipment . To meet the urban water supply pipe network, neither negative pressure, there are certain regulation and storage capacity when pumping water continuously without water demands during peak periods. Using computer controlled variable frequency pump at a constant number of revolutions of the original running tap water pressure to ensure that the user needs a constant pressure. Energy saving, environmental protection, low noise, constant water pressure and so on. With the development of secondary water pressure technology, box-type negative pressure water equipment from the fundamental solution to these problems. According to the "water supply equipment Promotion Center," the data show no negative pressure water equipment box without the construction of towers, small investment, small footprint, the use of water, gas automatic adjustment, automatic operation, automatic saving and water grid, even after power failure water, a few years after commissioning without care. Build towers to save and invest more than 70%, compared with the construction of high-λ tank save and invest 60 percent, significantly saving construction investment. Box no negative pressure water equipment specific instructions to ensure that the pipeline pressure: Adjust peak water tank at the entrance to the intelligent use of a solenoid valve to control water pressure and water λ. When the pipeline pressure drop when the pressure pump water from the tank, through the intelligent control, when the water tank is below a certain liquid λ λ, then open the valve from the drainage pipe network, water intake at this time to ensure that a certain pressure. This measure one can avoid the peak water, since peaking effect, the second is to avoid the common zero-pressure discharge tank, the pressure on the pipe network is a good protection. Unique configuration: with the introduction of international advanced technology and key equipment, combined with a dedicated pump. It uses water-cooled motors, water-cooled bearings, closed absolutely dripping? Noise below 50 decibels, to prevent small tank space, conventional motor heat and burn out the motor and equipment. Operational reliability: When the water peak, without water or tap water, water from the tank, greatly improving the reliability of water users, since the water supply in full compliance with specifications. Environmental pollution: this equipment in water tanks, pumps, pipes and valves · wading materials are used food grade stainless steel material, seal water, no secondary pollution, health and environmental protection. Energy: When the water pressure to meet the requirements of users of water, booster pump through frequency control dormant. When the non-peak water, water pressure and reach users of water pressure booster pump can be superimposed, take advantage of the difference between how much energy and pressure to make savings in water pressure (0.2-0.5MPa), based on the energy-saving effect is remarkable . Box no negative pressure water equipment and pool water from the water supply distinguish implementation point of view, no negative pressure water mainly by setting steady flow compensator, tandem municipal tap water, you can use 100% of the existing water pressure, with pressure steady flow compensation is fully sealed pressure vessel, completely isolated from the outside world, the complete elimination of water pollution. From the perspective of the stability of the water supply, no negative pressure water pressure is stable, and the pool water supply pressure changes occur, can not be stable. From the latter part of the maintenance and management point of view, no negative pressure water can be achieved automatic operation, no special management, product structure throughout the product integrity, saving time and effort. From the installation point of view, the need to build the pool water supply tank or tanks, the workload is relatively large, time-consuming and labor-intensive, time comparing plant. Box no negative pressure water supply equipment Scope 1, all kinds have been built, under construction, the application to be built in residential areas, apartment, office ￥, write ￥, hotels, schools, hospitals and other building secondary water supply system. 2, especially for tap water pressure during peak flow instability small high-rise, high-rise residential quarters, hotels, office of living water. 3, from the urban areas is more, the water pressure is low in industrial and mining life, production water. 4, the original pneumatic, pool renovation project (tanks) where frequency of water supply equipment. Box no negative pressure water equipment features a dual-mode supply: a pool (tank) where no negative frequency of water supply equipment and frequency of water supply pipe network overlying water supply equipment in two modes, can be automatically switched according to the water pressure and water flow, Run this way not only to avoid the generation of municipal pipe network negative, and to ensure the continuity of supply, this feature is a universal negative pressure water equipment can not be done. 2, energy efficient, low running costs: You can take advantage of the municipal water supply pipe network pressure difference how small, how much make up, does not produce negative pressure, and the traditional pool (tank) where frequency of water supply equipment can save 30% to 70% compared to. 3, regular renewal function: timing control system for the pool (tank) water automatically renewed, in order to maintain the pool (tank) in the freshness of the water. 4, automatic load shifting water supply function: When the water rush hour arrived, the control system according to the city network sensor signal mode is automatically switched to frequency of water supply, water peak automatically switch back negative pressure water equipment model, from a fundamental solution to the water supply during peak hours Water pressure and flow instability problems. 5, reliable operation: power can be maintained municipal water supply pipe network pressure; when the peak water or tap water without water, by the pool (tank) water, greatly improving the reliability of water users, water supply in full compliance with specifications. 6, the protection function: a perfect overload, short *, overvoltage, undervoltage, phase, overcurrent, short *, water, water and other automatic protection. In exceptional circumstances can signal alarm, self-test and fault diagnosis. Time does not relieve us of the damage suffered, but it allows us to become less afraid of injury. Time will not help us solve the problem, only to figure out how the original problem, is no longer important
