Kaifeng no negative pressure water supply equipment [Hunan Water Equipment Co., Ltd. China Merchants Walter] heart really wanted a field, and let go of what will sow the seeds, sooner or later, when conditions are ripe to grow fruit, or sweet or bitter , or trees, or prick all over the floor, your mind a move, that as the sower, and sometimes even with the harvest also unconscious. Honesty, service first, quality first, professional excellence. Negative pressure water equipment is based on the traditional water supply equipment developed on a direct connection with the water pipe network, and on the water pipe network does not produce any negative effects of complete water supply equipment; break through the traditional way of water supply reservoir is inseparable pond, reservoir water is generally supplied by the water pipe network, so that after the pressure of the water into the pool becomes zero, resulting in a large amount of energy wasted. It can completely replace the reservoir, can take full advantage of the pressure water pipe network directly or indirectly supply water to avoid secondary waste of energy and secondary pollution, significant savings in infrastructure investment and shorten the construction period, the equipment from Smart control cabinet, steady flow tank, water pump, meters, valves and piping, base, etc., suitable for all the needs of increased water pressure, a constant flow of water supply system. Negative pressure water equipment imported host governor, its own undervoltage, overvoltage, overcurrent, overload, short circuit, overheating, stall prevention, protection of the main functions, trouble-free use of up to 100,000 hours. Distribution control section, the use of intelligent control principle, convenient and practical, work status at a glance, easy to non-professionals quickly master negative pressure water equipment is especially suitable for the following places: ⑴ construction, expansion and renovation of residential buildings, residential , office buildings; ⑵ hotels, restaurants, etc.; ⑶ schools, military units, offices, dormitories and other water-intensive applications; ⑷ hospitals, shopping malls, convention centers, stadiums, public bathrooms and other public places; ⑸ city water pressure can not meet the Fire Hydrant fire water system or sprinkler systems and other water requirements; large flow ⑹ large factories, booster pump station, zone and other centralized water supply; production and living water ⑺ industrial and mining; ⑻ variety of circulating water system; ⑼ especially adapted particularly demanding on water quality water supply occasions. Negative pressure water equipment control principle: Use control to achieve constant pressure water supply, and with a regulating valve to achieve constant pressure water supply compared to energy-saving effect is very significant (can be calculated depending on the circumstances). Its advantages are: a, starting balance, starting current limit within the rated current, thus avoiding the impact on the grid at the start; b because the average pump speed is reduced, and thus extend the life of pumps and valves; c. Baicheng negative pressure water equipment can eliminate water hammer effect starting and stopping; Generally speaking, when controlled by a an electric motor, just so that you can match with the motor capacity and the actual motor capacity. When a control two motors simultaneously, in principle, with the motor capacity should be equal to the sum of the two motor capacity. No negative pressure water equipment operation: (1) When the municipal pipe network pressure, the device is in shutdown state, municipal water through the water tank, the bypass pipe water supply pipe network directly to the user. (2) When the municipal pipe network voltage, Baicheng negative pressure water equipment to start automatically, based on the speed of the original water pressure booster (constant) of water, due to the press, "how much less, make up" principle pressurized, so In full flow range that meets the needs of the user constant pressure water supply, while achieving energy efficient operation. Closed during the operation of the law of the sea is only equivalent to a length of tubing tank, fresh water continues to flow through the sanitary water tank (or pressure tank), is not subject to external contamination. (3) When the municipal water pressure is too low, the device is less than the tap water supply (water tank water), the water tank by municipal water storage volume to compensate for deficiencies. Water tank to provide maximum compensation amount of water and the total volume of the water tank fill the same V = V total. During the water tank to provide compensation for the amount of water by vacuum suppression (automatic exhaust valve), the air automatically enters the tank, you can avoid the municipal pipe network negative suction effect (the so-called cell-free vacuum suction process), and Water tank capacity can ensure the effective use of all is no negative pressure water equipment Product Features: 1. Energy efficient: no negative pressure water equipment full use of municipal water pressure heat much difference how much, effectively, maximize played a governor of the energy saving effect. 2. Clean and hygienic: form a continuous sealed pressurized water supply, fully maintained state water quality health standards for municipal water, avoid the water quality standards due to the pressurization system to reduce water pollution and various fundamental issues. 3. eliminate waste: not only eliminated the high water tank, but also completely abolished the ground (underground) tank pool, completely eliminated the tank overflow, regular cleaning of waste water caused. 4. No negative pressure water equipment operation and low noise: no negative pressure water district set up with full adjustment programs, most of the time, especially at night in a low-noise operating conditions. 5. Design a fully enclosed, both cushioning effect and dynamic compensation of the water tank tank, compared with the current market so-called cell-free vacuum tank, more practical significance, and control system can be simplified. 6. Series control system adequately summed up the domestic and international supply equipment design and manufacturing experience, the use of standardized universal control system technology solutions, can be changed by any vendor, regulators, PLC and other components, commissioning maintenance particularly convenient for product life-long service and laid a good foundation, not because of technological advances lead to service problems.
