摘 要：
设计了用于MQ-600型气流辅助式喷杆弥雾机的轴流风机。根据气流辅助式喷杆弥雾机喷施作物冠层的末速度原则,确定风机的风量、风压和出流速度等参数;以此作为风机设计的依据,设计计算了轴流风机的比转数、轮毂比、外径、叶片各截面气流全压分布等关键参数,进行了风机叶片选型、叶片各截面处弦长和叶片数量计算。并对风机驱动系统进行了设计。根据设计结果加工了物理样机,并对其性能进行了试验研究,试验结果表明,风机转速1 473 r/min时,风助风筒出口风速32.1 m/s,出口风下方0.5 m处风速8.6 m/s,风机性能满足使用要求。

摘 要：
In order to match the requirements of MQ-600 type air-assisted boom sprayer,the axial fan for air-assisted duct was designed.According to final velocity principle of air-assisted duct on crop canopy,the fan's air flow,air pressure and the flow velocity and other parameters were determined.The key parameters,such as ratio of axial fan speed,wheel hub ratio,diameter,blade pressure distribution of the whole flow cross-section were calculated.Then,the selection of fan blades,blade chord length of each section was calculated.According to the designed parameters,the physical prototype was built and its performance was studied.The results showed that when the fan speed was under 1 473 r/min,the outlet wind velocity of the duct was 32.1 m/s,and the wind velocity was 8.6 m/s at the 0.5 m blow the duct,which means the fans met performance requirements.
