摘要
采用数理统计和回归分析方法 ,对离心泵、混流泵汽蚀余量进行研究 ,通过统计和计算 ,得到离心泵、混流泵汽蚀余量的确定方法 ,并与 GB/ T130 0 6—— 91标准中汽蚀余量指标 (图线值 )进行比较 ,提出的公式计算平均相对误差小于图线值 ,对叶片泵研究、设计和试验具有实用价值。
The research on NPSH of centrifugal and mixed f low pump has been carried out by using the mathematical statistics and regression analysis.The establis he d method of NPSH for centrifugal and mixed-flow pump has been given through sta t istics and calculation.Compared with the index of NPSH(characteristic value)in GB/T 13006-91,this paper presents the relative average error in the calculation of formular which is less than characteristic value to the research,design and e xperiment in vane pump.
