摘要
本文着重分析了汽蚀的比R效应,推导出新的离心泵增速时的临界汽蚀余量相似定律。在现有大量工业试验数据的基础上,给出了新的汽蚀比R效应函数。
This paper analyzed the scale effects on cavitation for centrifugal pumps and derived a formula to calculate the critical NPSH when the rotating speed has been increased. Based upon a lot of existing testing data in industry, a new function related to the scale effects on cavitation is presented.
