【摘要】 直接空冷系统轴流风机的优化选型和设计是空气供给系统设计的关键技术,它对于直接空冷系统的优化和经济运行具有重要的意义。轴流风机的风压取决于空气流经直接空冷凝汽器时各部分的阻力。分析了空气流经"A"形直接空冷凝汽器各部分时阻力产生的原因。确定了空气流经直接空冷凝汽器时各部分的阻力系数,可为直接空冷系统的优化设计提供帮助。更多还原

【Abstract】 In the direct air cooling system,the key technology of air supply system is the optimal selection and design of axial fan.It is of great importance on the optimal design and economical operation of air cooling system.The static pressure of the axial fan depends on the flow resistance of the air cooled condenser(ACC).The causes of pressure losses when air passing through each part of A-shape air cooled condenser were analyzed.The resistance coefficient at different part of the bundles was determined.It offers good help for the optimal design of direct air cooling system.更多还原
