摘 要:随着我国各大城市内涝频发和洪涝灾害日益严重,应急供排水抢险装备的重要性日益凸显。为满足这一需求,总结了应急排水抢险车及高功率密度潜水电泵技术发展现状,并研发出一种新型大流量潜水电泵,采用永磁同步电机驱动,具有高功率密度、大排量、轻巧便携的特点。为了提高潜水电泵的综合性能,采用数值模拟和试验验证相结合的方法,对潜水电泵内部流动特性进行分析。计算模型为SST k-ω湍流模型,重点选取了0.6Q、0.8Q、0.9Q、1.0Q、1.1Q和1.2Q工况;选取具有代表性的速度分布云图,对比分析不同流量下泵内部流动结构及其变化规律;提取叶轮叶片与导叶叶片的叶片压力载荷曲线。装备了高功率密度便携式潜水电泵的应急排水抢险车具有广阔的应用前景,顺应了应急排水行业发展趋势。本文的研究有助于提升潜水电泵的水动力性能,从而提高防灾救灾能力。With the frequent occurrence of urban waterlogging and the increasing severity of flood disasters in China,the importance of emergency drainage and rescue equipment is becoming increasingly prominent.To meet this demand,the development of emergency rescue vehicles and high-power density submersible pumps are summarized,and a new type of high-flow submersible electric pump is developed,which is driven by a permanent magnet synchronous motor,features high power density,large displacement,and lightweight portability.In order to improve the comprehensive performance of the submersible pump,a combination of numerical simulation and experimental verification methods is employed,to investigate the internal flow characteristics of the submersible pump.With the SST k-ωturbulence model as the calculation model,various flow rates(0.6Q,0.8Q,0.9Q,1.0Q,1.1Q,and 1.2Q)are selected;Representative velocity distribution maps are selected to compare and analyze the internal flow structures and their variations under different flow rates;The pressure load curves of the impeller blades and guide vanes are extracted.The application of the high-power density portable submersible pump in this emergency drainage and rescue vehicle has broad prospects and aligns with the development trend of the emergency drainage industry.The research in this study contributes to improving the hydraulic performance of submersible pumps,thereby enhancing urban disaster prevention and mitigation capabilities.
