扁平扇形喷嘴的设计研究

对侧向V型狭缝式扁平扇形喷嘴的内部结构参数设计方法进行了研究.使用该方法对一个喷嘴进行了设计,实际使用中喷洒效果符合要求.分析得出了侧向V型狭缝式扁平扇形喷嘴内部结构参数和流量阃的关系:喷嘴内圆柱面半径和V型槽底部至内圆柱面轴线的距离必在一族等式约束曲线上取值,且曲线随流量增大而上移;当内圆柱面半径一定时,喷嘴流量随V型槽切口深度增大而非线性增大;当V型槽切口深度一定时,喷嘴流量随内圆柱面半径增大而非线性增大.

Research on the Design of Flat Fan Nozzles

The design approach of internal structure parameters of flat fan nozzles with a lateral V-shaped cut was presented. With the proposed approach,a flat fan nozzle was designed and its spray effect accords with the demands. The relationship between internal structure parameters and the flow rate of a flat fan nozzle with a lateral V-shaped cut was analyzed. The radius of internal cylinder and the distance between the bottom of V-shaped cut and the axis of internal cylinder achieved their values on a group of c...
