本文介绍的是一种图解解析方法,根据计算精度的要求可分二步进行。第一步导出的为解析计算公式,能满足一般近似计算的要求;第二步的分析中由于已较合理地考虑了机组特性以及水击压力过程对转速升高的影响,因此精度较高。文中最后列出的实例与电算结果作了比较。
This article describes a graphical analysis method, according to the requirements of accuracy can be divided into two steps. The first step is to calculate the analytical formula to meet the general approximate calculation requirements; the second step of the analysis as a more reasonable consideration of the unit characteristics and the impact of water hammer pressure on the speed increase, so the accuracy is higher. The last example presented in this paper is compared with the calculation results.
