水力脉冲空化射流发生器参数优化试验研究

An experimental study of the parametric optimization of the hydro-pulse cavitation jet generator

为优化水力脉冲空化射流发生器的参数,采用设计的试验模拟工具及相应的试验台架进行了室内试验。着重研究了叶轮叶片数量、排量对压力波动效果的影响。试验结果表明,随着排量的增加,经过水力脉冲空化射流发生器的流体平均压力增大,压力波动振幅增大;在试验条件下,排量为13.67L/s时,采用3片叶轮,平均压力为1.25MPa,产生的脉冲效果明显,压力波动振幅为1.1MPa。

To optimize the parameters of the hydro-pulse cavitation jet generator,a laboratory experiment was conducted by adopting the designed simulation test tools and the corresponding test stand. The research focuses on the effect of the number of the impeller blades and displacement on the pressure fluctuation. The experimental results show that,with the increase of displacement,the pressure fluctuation amplitude of the fluid flowing through the hydro-pulse cavitation jet generator will increase. Under the experimental conditions,when the displacement is 13.67 L/s,adoption of the three-blade impeller will produce a noticeable pulse effect,with the pressure fluctuation amplitude being 1.1 MPa.
