| 摘 要： | 滑移系数是计算离心泵理论扬程的关键．分析了滑移系数的定义、本质及国内外滑移系数的研究状况．通过对大量优秀离心泵效率的计算，以试验效率为标准比较了目前离心泵常用的斯托道拉、威斯奈和斯基克饮等滑移系数计算公式的精度．计算结果表明，与试验效率相比，离心泵在比转数小于65时威斯奈公式的计算结果更为精确；比转数大于65时斯基克饮公式的计算更为准确。

| Abstract: | Slip factor of centrifugal pumps is very important to theoretical head calculation.The present research situations on slip factor of centrifugal pumps,definition and characters of slip factor are(reviewed).Based on the practical efficiency calculation of many excellent centrifugal pumps,the Stodola,Stechkin,and Weisner slip coefficient formulas are compared.The standard of comparison is experiment efficiency.Compared with experiment efficiency,the research indicates that Weisner formula(n_s<65) and Stechkin formula(n_s>65) are more accurate for centrifugal pumps and that the Stodola formula is not suitable for centrifugal pumps.centrifugal pump;slip factor;precision;theory head;characteristics prediction |
