水泵性能检测是保障水泵市场产品质量的重要手段,本文介绍了用最小二乘法对水泵性能检测试验数据进行拟合,以达到对水泵运行工况和性能进行分析的目的。基于VB编程,设计开发了水泵性能曲线绘制和分析软件,具有水泵性能曲线动态绘制、打印输出和自动纠错等功能,大大提高了水泵性能试验数据分析处理效率。最后通过实际算例对软件进行了应用分析。
Pump performance testing is an important means to ensure the quality of the pump market. This paper introduces the use of least square method to test the pump performance test data fitting, in order to achieve the pump operating conditions and performance analysis purposes. Based on VB programming, the design and development of pump performance curve drawing and analysis software, with the pump performance curve of dynamic rendering, printout and automatic error correction and other functions, greatly improving the pump performance test data analysis and processing efficiency. Finally, through the actual example of the software application analysis.
