摘要
根据大伙房输水工程布置特点,对输水系统加压泵站不同阀门启闭运行条件下,输水管道内的最大水锤正压和最大水锤负压进行数值研究,考察工程运行安全指标并提出合理的优化设计方案。采用瞬变流模型方程,运用Fortran程序语言编制程序,对水力过渡过程进行数值分析计算。最终给出不同运行工况下阀门启闭方式的推荐方案,并基于各稳压塔溢流量给出稳压塔的修正设计方案。
According to the layout characteristics for water conveyance project of Dahuofang reservoir,the paper studies the maximum water hummer positive and negative pressure of in conveyance pipe,investigates safety operation index of the project,provides rational optimized design scheme under the open and close operation condition of different valves for booster pumping station of conveyance system.The paper presents numerical analysis of hydraulic transient process with transient flow model equation and For tranlanguage programming,and provides the recommended scheme of valve operation for different operational conditions and the correction design scheme of the voltage stabilization tower based on the spillway discharge of kinds of stabilization tower.
