摘要
本文首先用数学方程分析法研究了以液体为工作介质的射流泵相似理论,接着再用因次分析法加以研究验证,最后筛选确定出射流泵在不同密度液体和同一密度液体运行工况下的相似准则。结果表明:数学方程分析法和因次分析法所推导出来的相似准则结果一致。并以此为基础推导研究了射流泵在不完全相似时的相似准则。
The similarity theory of Jet Pump fed with liquid is studied with mathematic and dimensional methods. The similarity criterions of the Pump are given. The results show that the similarity criterions derived from mathematic method are the same as from dimensional method. Based on the above-mentioned principles, the similarity criterions of the incomplete geometric similarity for the Pump are given.
