Stress Analysis and Optimization Design of Steel Lining in Flow Channel of Large Pumping Station
The flow channel of pump station determines the suction condition of the pump inlet,which has a great influence on the efficiency,engineering investment and safety operation of the pump device.In order to improve the surface flatness of the flow channel and reduce the influence of the flow form on the efficiency of the pump device,the inlet and outlet flow channels are often designed as permanent steel lining in the design of the flow channel of medium-sized and large pump stations.Taking the steel lining of flow channel in a large pumping station as an example,the load analysis in the design process of the steel lining of the flow channel is described.The design methods of the steel lining panel,stiffening rib,cross brace and vertical pole are optimized.The deformation,internal force,stress and stability of the main components are checked.And the sensitive factors affecting the stress of the steel lining are analyzed,which can provide reference for the design and construction of similar projects.
