Similarity Criterion and Conversion Equation of Critical Submergence Depth for Intakes of Pumping Stations

结合大型斜式轴流泵站水力模型临界淹没深度试验研究 ,就泵站进水口临界淹没深度相似准则进行探讨 ,提出了泵站进水口临界淹没深度换算公式 .与其它泵站进水口临界淹没深度换算公式进行了比较 ,验证了公式的适用性 .

Based on the experimental study of critical submergence depth with the hydraulic model of large inclined axial flow pumping stations, the similarity criterion of critical submergence depth for intakes is studied and an equation, for the conversion of critical submergence depth of the intake, is proposed. According to the data of a model pumping station, the present equation is compared with other conversion equations, and its applicability is verified.[KH2D]
