Seiko quality driven water Shengbokaisi a negative pressure water equipment, frequency negative pressure water equipment Product Overview: frequency without negative pressure water equipment, the twenty-first century is the inevitable trend of development of water supply equipment in the field. No negative pressure (no suction) intelligent frequency of water supply equipment is not building a pool, do not set up water tanks, water pipes can be connected in series with direct pressure, and significantly festival capital, energy, water supply equipment from contamination. Second, the frequency without negative pressure water equipment Features: do not build pools, water tanks, water pipe network directly connected in series with pressurized water, can take advantage of existing water pressure; improve water quality, clean water directly after pressurization equipment for the user, non-vacuum tank embalmed, sealed connectors, water without any pollution, water quality is good quality, the user can use to meet the health standards for tap water, to solve the problem of secondary pollution. Energy savings of 50% to 90%; water-saving significant, overcome pools run, run, drop, leakage, seepage phenomenon; do not build pumping stations, water basins, more than 60% reduction in investment; water quality improvement, constant pressure to solve the two secondary pollution problems; equipment was ordered to extend more than five times; power off the water (to restore the original water supply pipe network pressure); fully automatic operation. Third, the frequency without negative pressure water equipment Scope 1, new residential or office buildings and other domestic use. 2, the lower water pressure can not meet the fire water. 3, the re-election of the existing pressure water supply equipment, can take advantage of the existing pressure tank. 4, has built the pool, you can use non-vacuum equipment and pool shared water supply, further energy saving. 5, large intermediate water plant booster pump station. 6, industrial and mining production, domestic water and so on. 7, a variety of circulating water system. Fourth, the frequency without negative pressure water supply equipment works 1, when the water pressure is lower than required by the user to set PZ pressure Py, the programmable controller automatically frequency soft start to run until the actual pipeline pressure Pz = Py, can programmable controllers only control variable frequency pump at a constant speed operation. Pz ultrahigh water pressure, the lower the frequency of the pump speed, the lower the water pressure Pz, pump-speed is higher. When the water pressure Pz = Py, the lead pump stopped working both full advantage of the existing water pressure, but also to ensure that the user needs a constant pressure. 2, the frequency of the pump inlet and non-vacuum tank connected. Detection time is no negative pressure inside the tank when the programmable controller, by controlling the vacuum suppressor to stabilize the non-vacuum tank and the water pressure so that it does not produce negative pressure, so as to ensure normal supply water pipe network. 3, water without water, the equipment automatically shut down, the water automatically boot, automatically restore power supply tap water pressure. Variable product is no negative pressure water equipment installation requirements change product has no negative pressure water equipment consisting mainly of high frequency adjustment intelligent control cabinet, sensor, water pump, base and pipe accessories. So installation of the device, is to install electrical control cabinet and pump unit and piping system. Electrical control cabinet layout and installation of intelligent electrical control cabinet, mainly by the frequency regulator, programmable controllers, regulators, various switch relays, contactors and other electrical components of the composition. Shengbokaisi stainless steel tanks often used SUS304, SUS316L, SUS444 and other stainless steel plate stamping. General stamping into three dimensions, namely, 1x1 meters, 1x0.5 meters and 0.5x0.5 meters three, surrounding by TIG welding of high strength, light weight, low cost, environmental health and other characteristics.
