| 摘 要： | 目前进行燃气中压输配管网水力计算时,一般采用值为0.55的流量折算系数把途泄流量分配到相邻的节点流量中,其计算结果有时误差较大,甚至超出工程精度要求。推导出适合中压管网的流量折算系数,对采用此系数的简化方法进行了实例验证,指出简化方法的适用范围。此简化方法与目前的方法相比可提高计算精度。

| Abstract: | At the present time,when the hydraulic calculation of medium pressure gas distribution network is conducted,0.55 is generally used as flow conversion coefficient for distributing the way leak flow into the near node flow,and the error of calculation result is large sometimes,even exceeds the range of engineering precision.A flow conversion coefficient that suits for medium pressure gas network is deduced,the simplified method using this coefficient is verified with an example,and the scope of application of the simplified method is pointed out.The simplified method can increase the calculation precision compared with the present methods,. |
