Abstract

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.
