侧斜向进水螺旋流消能装置的试验研究

管道消能装置是有压输水管道系统中的重要组成部分,消能效率较高的消能装置可对系统下游设施起到良好的保护作用。介绍了3种侧斜向进水的管道消能装置,研究了它们的消能效果,并对消能效率进行分析,得到这3种消能装置均能消除来流压头的50%以上,表明这3种消能装置结构基本合理,可作为管道消能装置设计的依据。

Study on the Experiment of Spiral Energy-counteract Dingus With the Side-diagonal Inflow

The Energy-counteract dingus in the pipe is one of the most important parts of the pressed water-transporting pipe system. An energy-counteract dingus with high efficiency would be a fine protection for the establishments of the lower stretch. This paper introduces three kinds of energy-counteract dinguses with side-diagonal orifice inflow, studies on their effect and efficiency of energy-counteract, and points out that the three kinds of dinguses do have an efficiency of canceling out the inflow pressure head of more than 50%, which shows that the three dinguses have reasonable structure and can be used as the basis of the energy-counteract dingus design.
