Dehong living water supply equipment Equipment Co. Walter Merchants national agency, secondary water supply equipment sailing toward life pressure water supply equipment prepare Description Fairview areas: life pressure water supply equipment equipment suitable for: high-rise buildings, housing residential building, enterprises and other life, fire water systems, HVAC, central air circulation and quality of water supply systems. Various types of industrial and mining production water (such as cooling water, boiler water systems and other industrial needs constant production of water). Constant pressure oil system, oil pipelines, oil depots, pumping stations, oil port and so on. Various types of water plant, water booster pump station. All kinds of water, sewage, waste water treatment plant. Large squares, green parks and farm irrigation station. Musical fountain. Energy conservation, energy transformation of the user's original pressurization system. Living life pressure water supply equipment introduced pressure water supply equipment equipment generally consists of a buffer tank, water pump, pressure tank control cabinet and control instrumentation components, each part as follows: a, buffer tank: It is connected to the device at the entrance to the pressure tank, referred to a buffer tank . Water run-time volume of the compressed air tank part, by compressed air energy storage, has a good impact on the various mutations eliminate the effect of slowing, while the municipal water supply has a dynamic compensation. There are two kinds of buffer tank with different structures: a buffer tank with natural rubber diaphragm membrane material, due entirely closed more conducive to maintaining water quality standards; ordinary steel buffer tank, wall coated with anti-corrosion coatings meet the health standards, but will work with qi contact with the outside air. Buffer tank can be connected in series, can also be connected and used for the same out of the water pipes, as a branch of the municipal pipeline phase. b, the pump unit: selection of the company has a non-overloading characteristics of pumps, whose operating characteristics can be adapted to a wide range of pressure variation of water, does not produce overload. c, pressure tank: its role and usually twice a supercharger pressure water supply equipment life prepared in the same pressure tank, this series of products using standard micro diaphragm pressure tank, the main advantage of its packing function, is conducive intelligent automatic equipment energy-saving control. d, frequency control cabinet: to use the full frequency control system, that all pumps are used in frequency control drag. May also be part of the frequency control system (only a sample of standard products for frequency control drag pump). e, a bypass line: If the municipal water supply to meet the pressure requirements usually, only the peak pressure in the water supply shortage, loadable bypass pipe, can drop down the municipal water and pressurized water to achieve automatic switching operation. Life pressure water supply equipment equipment characteristics: (1) When the municipal pipe network pressure, the device is in shutdown state, municipal water buffer tank too, bypass pipe water supply pipe network directly to the user. (2) When the municipal pipe network voltage, the device starts automatically on the basis of the original frequency control without pressure booster (constant pressure) water supply. Because it is by "how much less, make up" principle pressurized, so that the entire flow range pressure water supply to meet the user's needs, while achieving energy efficient operation. Closed during the operation of the buffer tank for quite some piping fresh health unsolicited Miao constantly flowing water tank, not subject to external contamination. (3) equipment operation, part of the buffer tank volume of compressed air (same pressure and municipal water pressure), thus storing some pressure potential energy, energy storage can greatly depend on the mitigation of the impact of various municipal water, while the municipal Water has a dynamic clipping compensation, when the municipal services dropped from P2 pressure P1, the relationship between the total volume of the buffer tank to provide the maximum amount of water and buffer tank to compensate for: V # = (1-P1 / P2) V total = KV total V # - municipal water supply peak pressure drops during P1 from P2 compensation given water tank of water (m3) P1- municipal water peak of the lowest pressure (absolute pressure) P2- before the peak of the municipal water supply pressure (absolute pressure) V total - the total volume of the water tank (m3)
