摘要
本文提供了两种能与离心泵 Q～H 曲线全程拟合的函数表达式——代数多项式和流量指数式,并详细介绍了几种不同的构造方法。以函数表达式实列及其计算结果比较说明了代数多项式拟合精度高,曲线适应范围广;流量指数式构造简单,使用方便的特点。
Two mathematical function formulae,an algebra polynomial and a flow discharge exponential structure formations,which can get full fitting with Q～H curves of centrifugal pump were described in this paper.By some practical examples indicated that the algebra polynomial has high fitting accuracy with widerange application and the flow discharge exponential with concise structure is characterized as easy as to use.
