室内消防泵的水力特性分析与叶轮改型优化设计
Hydraulic Characterization and Impeller Optimization Design of Indoor Fire Pumps
摘要
Abstract
To improve the performance of the engineering centrifugal fire pump,a high-performance centrifugal fire pump with high efficiency,low vibration and flat head curve was designed and optimized based on the pro-totype pump.Aimed at the existing problems of the fire pump,with the computational fluid dynamics method,3 optimization plans were designed and compared through increase of the auxiliary blade and change of the aux-iliary blade length.The results show that,all the 3 optimization plans can improve the fire pump performance to some extent.Optimization plan 2 has a lift of 42.6 m at the design point and an efficiency of 68.46％,eliminates the hump phenomenon,reduces the shaft power and improves the pump efficiency,which is synthetically cho-sen as the best plan.The research results have guiding significance for improving the fire pump performance and reducing the fire pump shaft power.关键词
