Beijing no negative pressure water supply equipment Equipment Co. Walter negative pressure water supply equipment to solve the traditional origin of domestic water supply systems, vacuum problem direct access to the water pipe network pump water pipe network generated by our innovative research and development can be new generation negative pressure water supply equipment (pressurized pipe network adjustment device). The product not only solve the problem of secondary pollution of underground pools, but also can be pure water equipment, drinking water directly as pressurized device that can be used in any one needs to pipe pressurized water supply system. No negative pressure water supply equipment works computer set for the pump pressure of work, both users of water pressure. When the domestic water supply, equipment operating at low frequency state, the drive time pressure in the pipe, and set the value of the feedback computing and comparing the calculated values, if required by the user is higher than the pressure in the pipe pressure (set pressure) will automatically reduce output frequency, thus reducing the speed of the pump, the water is reduced. If the pressure in the pipe below the user-desired pressure (set pressure) will automatically increase the output frequency, which is the pump speed increases, the amount of water increases, when a pump is running can not meet user needs, the pump automatically put into each other, to ensure that the user's use of pressure. When the pressure of the water pipe network is increased when the pressure reaches the user, the drive to reduce speed after a delay until after the shutdown. Only when the pressure falls below a preset pressure value, the inverter will start working again. Working knowledge of inverter pumps to meet the support of poor water pressure and the pressure of the pipe network. Significantly saving energy. When the flow regulator when the pressure is lower than atmospheric pressure, flow regulator installed in the top of the vacuum to eliminate automatically opens into the gas flow regulator, eliminate the negative pressure. When the pressure increases within the flow regulator, and can exclude the excess gas flow regulator, the so fills the water flow regulator, in order to prepare for the next peak water use. When water fills the flow regulator, vacuum mounted on top of the elimination of the flow regulator automatically shut down to prevent overflow of water supply equipment without negative pressure core device - vacuum to eliminate vacuum to eliminate it is the core of the device, It relies on the elimination of the negative pressure in the pipe network, which does not affect the surrounding water, protect the pipe network and equipment to the municipal water supply requirements. It works relatively simple, with a composite exhaust valve is exactly the same. It mainly consists of a float to work, move vertically up and down according to drive the float inside jars of water without the negative pressure regulating valve lift control on and off, so as to adjust the intake and exhaust cans, while achieving a tank vacuum (less than when the water tank) is eliminated. Remove the vacuum is a new term, so a lot of manufacturers in its body a big fuss, doing a bit of mystery (packaged very well). In fact, it is only out of an automatic air valve, but the cost is not high. No negative pressure water supply equipment maintenance and repair a device in the system should be put into operation before cleaning, purging, in order to avoid impurities into the pump equipment damage. 2, the pump should not be long-term operation in the case of the outlet valve is fully closed, nor should run at the performance curve hump, not air operation, allowing the seal when the seal with packing 10 to 20 drops min leaks. 3 runtime bearing temperature shall not exceed 75 degrees Celsius. 4, water pump bearings in response to run 500 hours once every refueling. 5, the equipment long-term outage should take necessary measures to prevent contamination and corrosion equipment, winter outage antifreeze, precautionary measures should be adopted. 6, the operation of the equipment should be considered preliminary implementation of sewage water quality. Run no negative pressure water supply equipment: no negative pressure water supply equipment, how much water users are 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. 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.
