摘要
本文根据ISO3555—1977规定方法确定泵的NPSHr值,对不同比转速的泵进行了不同转速的汽蚀试验。实验数据经数理统计处理,得出不同转速下NPSHr的换算关系,新的关系式与现行的换算关系有较大的区别,作者对这种区别进行了理论分析。
Cavitation tests were done on several centrifugal pumps at different rotative speeds and NPSHr values were attained in accordance wi th ISO3555-1977. Conversions of NPSHr values at different rotative speeds were gotten by statistics. The new conversion differs from the one now used greatly and the author analyses the reasons of the differences.
