摘要
通过分析论证,导出水力喷射泵效率计算中无量纲压力比的正确计算公式,指出文献[1]中无量纲压力比计算公式的错误;认为喷射泵无量纲压力比是选定喷射泵的重要性能参数,运用正确的计算公式才能使泵的选定趋于合理。
The rational selection of jet pumps is based on correct calculation of the dimensionless pressure ratio. After discussing the calculation errors in a certain literature, this article, introduces a correct formula of calculating the dimensionless pressure ratio for the computation of jet pump efficiency.
