摘要
结合工程实例和水泵样本数据,利用EXCEL数据分析功能,对水泵性能曲线进行拟合,得出水泵性能曲线方程式。利用拟合方程式计算出水泵实际工况点,用以校验水泵选型的合理性。
Combining with the engineering example and pump sample data, and using data analysis function of excel, the performance curve of pump was fitted, and then the pump performance curve equation was obtained. Calculating the actual oper- ating point of pump by the fitting equation, is used to check the rationality of pump selection.
