摘　　要：针对诱导风机应用于水电站厂房通风改造,结合诱导通风原理,进行风机应用特性分析,并根据分析结果进行风机的选型示例,提出了诱导风机应用在水电站通风改造中的建议。风机纵向接力间距与下方净空要求是确保诱导风机气流连续性的关键影响因素。通过计算分析表明,风机纵向接力间距最大不宜超过10 m,同时风机布置还应考虑下方的净空要求,确保射流不被下方障碍物遮挡。在确定风机布置数量时应综合考虑风量、接力间距、净空要求、经济性等因素。In view of the application of induced fans in ventilation transformation of hydropower plant buildings,combined with the principle of induced ventilation,the application characteristics of fans are analyzed,and based on the analysis results,an example of fan selection is given,and suggestions for the application of induced fans in ventilation transformation of hydropower plants are put forward.The longitudinal relay spacing and lower clearance requirements of the fan are the key factors to ensure the continuity of induced fan airflow.The calculation and analysis show that maximum longitudinal relay distance of the fan should not exceed 10m,and the clearance requirement below should also be considered in the fan layout to ensure that jet is not blocked by obstacles below.When determining the number of fans,the air volume,relay spacing,clearance requirements,economy and other factors should be considered comprehensively.
