Inverter constant pressure water supply system      Hangzhou Tengfei System inverter constant pressure water supply system is the “Promoting project of scientific and technological achievements” of China Ministry of Construction and has been list on “National major and new products” by China Ministry of Science and Technology.     This system has frequency control technology, computer technology and electrical control technology and has adopted built-in PID function converter of world’s electrically leader ABB Multinational Group and matched Siemens’s PLC Control System. It has adopted low-voltage apparatus with Korea LG original packaging and matched good quality brand vertical multi-stage centrifugal pump (slow-speed of revolution, low noise), food grade non-corrosive steel non-negative pressure flow stabilization tank and Italia original packaging flow stabilization tank. The mode of operation could be chosen by auto- or handle. If there are some trouble, it could be chosen by handle operation in order to assure the water supply. Our professional engineer do the best design according to customers’ demands and supply the cargo with whole set (could be ordered by one piece), supply the service of installation and debugging, free technical training, finishing hand in the key project and repairing. System characteristics: 1、Non-negative pressure 2、Electricity-saving and energy-saving 3、Water conservation and resources nurse4、Prevent the secondary pollutant 5、Complete function 6、High responsibility 7、Intellectualize 8、Designed by personalize Basic parameter ★ Flow range: 1-10000m3/h ★Pressure range: 0-2.5Mpa; Pressure-Control Precision≥0.01MPa ★ environment temperature: 0-40°C ★Relative humidity: below 90% (part ofelectrical control) ★powder source: 380V（±10%）；48/63Hz ★Control mode: parallel connected with one-piece set or multi-sets, exit with constant pressure or transform. ★Operation mode: frequency conversion: automation; power frequency: handle ★ power frequency start mode: electric machinery power≤15kw direct starting; electric machinery power＞15kw reducedvoltage start Application range ★Production in industrial and miningenterprise; supply water on the tall structure and biotope Living water: water supply from all sorts of water plant and booster station; water charging from all sort of industry, civil hot water boiler; water reuse system of air condition and produce line.
