【摘要】 叙述了国家级旅游风景区扬州瘦西湖水环境治理工程中的输水管道水力模型试验。该试验研究了各种工况下管路压强和水头损失。包括主要运行工况在驼峰段虹吸过程的观察和测试结果,主要工况在管道最高断面处通大气的条件下管道压强分布、水头损失的测定。试验表明该输水管道系统运行稳定可靠,虹吸状态下输水运行经济;水力损失占总扬程比例较少;不同工况下单泵流量相差不大。该试验对我国同类城市中水环境改善工程具有较强的指导意义。更多还原

【Abstract】 This paper narrated the hydraulic model test research of water distribution pipeline system of water environment regulation Project of Slender West Lake in Yangzhou.This test studies pipeline pressure and head loss under each kind of operating mode,also studies observation and test of main paragraph siphonic hump in main operating mode.The main operating modes test the distribution of pipeline pressure and head loss in the pipeline highest cross-section under the condition of atmosphere pressure.Tests shows that the aqueduct system is stable and reliable.Water delivery is economical operation under Siphon state.Hydraulic loss takes less total head proportions.The single pump flow is little difference under different operating modes.The test has stronger directive significance to water environmental improvement project in the similar city of our country.更多还原
