| This paper studies on automatic sprinkler system--one of the main measures of structuralfire protection. Automatic sprinkler system is very important but apt to cause troubles duringthe progress of water supply and drainage design. After analyzing of automatic sprinklersystem classification, composition and the problems happened in the process of designing, itmakes clear the functions and the layouts. In addition, putting forward the measures to solvethe most common problems appearing in design and construction, and then normalize thesystem settings, so that people fresh specialized in the water supply and drainage design mayuse for reference.After analyzing the basic hydraulic calculation methods of automatic sprinkler systemand the current hydraulic calculation methods of china in detail, we point out the defects andthe necessity of improving hydraulic calculation method. According to hydraulics principleand hydraulic calculation formula, and theoretically deducing the discharge relation betweensprayers on branch lines, we put forward an improved characteristic coefficient method.Manual hydraulic calculation of automatic sprinkler system in engineering application iscomplex and cumbersome, and easy to result inaccuracies. To solve such problem,constructing a mathematical model for hydraulic calculation of automatic sprinkler system,based on 《Automatic sprinkler system design standard》and the basic formula of thehydraulic calculation method. With Visual Basic6.0writing calculation software, computerizethe hydraulic calculation of automatic sprinkler system, so as to improve the speed and theaccuracy of hydraulic calculation. When hydraulic calculation software is applied to projectdesign, the effect could be good. It brings certain practical significance to the optimizationdesign of automatic sprinkler system. |
