摘要(Abstract):

对国内外大量低比转速离心泵有关资料进行了统计研究和计算 ,分析了低比转速泵内各种水力损失和结构指标 ,提出了低比转速离心泵的比转速划分范围 ,这对低比转速泵的研究和设计具有现实意义
Statistics research and calculation on the large amount of information about low specific speed centrifugal pump from homeland and abroad has been performed. Varous hydraulic loss and structure index has been analyzed. Therefore, the delimitation of specific speed on the low specific speed centrifugal pump has been offered.

关键词(KeyWords): 离心泵;低比转速;统计
