Automatic Sprinkler Water Supply System Design

Along with reform and open policy penetrating with our country national strength enhancement, the automatic deluge system widely applies in the engineering construction, is automatically suppresses the initial period fire the best measure, may reduce the fire damage to the threshold.The design of engineering background Indus Avenue building,using programmable controllers,converters,water pumps,pressure sensors and other major components to build a regional control of distributed contorol system to achieve the building's fire sprinker system water supply.system realize constant pressure of wate supply,keep a low constant pressure during living state and a high constant pressure on fire state respectively.On fire state runing show that the designed system fulls variety of state water needs,saves investment in fixed assets,reducies the footprint,while reduce the amount of equipment maintenance and management,with a certain economic advantage.The thesis describes the design of water supply programs,type of system options, control system hardware selection,process design,as communication,approach,how the pump speed with PLC and inverter to implement constant pressure water supply in fire water supply applications.
