Optimization Design on Expansion Project of Pumping Station Based on Existing Structure
The expansion project of rainwater pumping station which adjacent to the Yangtze River is limited by sev-eral factors,such as Regulations on Seawall Management.As a result,the expansion project must be based on the exist-ing structure and crossing-dyke drainage pipelines.How to realize its full potential and ensure the safe and stable opera-tion of pumps,taking the expansion project of rainwater pumping station for the Luojing Port Area in Shanghai for an ex-ample,The CFD was used for flow pattern analysis of puming station.The influence of flow increase on intake sump is assessed,including the flow pattern in intake sump and section velocity distributions.The optimization scheme of anti-ro-tation plate was proposed,and the effect of flow pattern control was analyzed.It is found that an increased risk of the vortex formation is associated with the water flow increase,which might give rise to eccentric vibration.It turns out that anti-rotation plate indicates a significant rectification effect on pump inlet,which might be benefitted to ensure secure-and-reliable operation,and maximize the capacity of drainage system.The research results can provide a reference for the op-timal design of pumping station expansion projects.
