【摘要】 曹妃甸工业区供水工程输水管线长,在管线上游沿地形有两处明显的凸部,在水泵开、停机的水力过渡过程中有可能引发巨大的水锤升压,特别是停电或其他原因产生的事故停泵可能引发水锤事故,严重危及供水工程的安全运行。通过停泵水锤防护措施的比选,为确定实用可靠的水泵启动方案提供技术支持。更多还原

【Abstract】 The water conveyance pipeline of Caofeidian industrial area water supply project is long.There are two obvious convex parts in the pipeline upstream along the terrain.In the hydraulic transition process of the open or shutdown pump,water hammer may have triggered a massive boost.Especially the pump stop which caused by the power failure or other reasons may cause the water hammer accident,it seriously endangers the safety of water supply engineering operation.Through the calculation and researching hydraulic transition process which caused by the part or all of the pump pumping accident,we can provide technical support for the eventual identification of reliable water pump start-up scheme.更多还原
