摘  要:
对核心部件射流元件依靠水流的科恩达效应驱动并控制喷头步进转动的PXSB型双向步进式全射流喷枪的水力性能进行了研究。分析了影响喷枪射程、射高、水量分布的主要因素,试验分析了工作压力及射流元件结构参数对喷枪主要水力性能的影响规律,获得双向步进全射流喷枪最佳工作结构尺寸,为建立双向步进式全射流喷枪设计方法提供了依据。通过国内外大中型旋转式喷枪的水力性能对比,表明双向步进式全射流喷枪结构简单、喷洒性能优良。

摘  要:
PXSB two-ways step running complete fluidic rain gun is a new type of large-middle rotary sprinkler.The key component of the sprinkler,fluidic element,provides the driving force and controls the movement of the sprinkler based on Coanda effect.Hydraulic performance of the rain gun was tested.The main influencing factors to the range,height and rainfall distribution were analyzed.The influences of the working pressure and the structure parameters on the main hydraulic performance of the rain gun under its working states have been obtained by the experiments.The best geometrical size was achieved at the experiments,which provided a basis in building the design method of the two-ways step running complete fluidic rain gun.A comparison of hydraulic performance was made between the complete fluidic rain gun and the other large-middle rotary sprinkler.According to the results,the two-ways step running complete fluidic rain gun has better performance than the others.
