By selecting the appropriate basis functions according to the variation of vane pump regulating performance curves, we analysed the relationship in blade angle, flow, and head (or shaft power) based on surface fitting, and we established a parametric model, proposed the solution of the problem. The calculation of the example shows that the model has a high correlation coefficient, and has a simple mathematical expression, which is helpful for further application and popularization.
