- W2356220331 abstract "Decompression tower bottom pump is the important equipment in oil refining equipment.The finite-element analysis based on fluid-solid coupling is used to check pump casing' reliability.The three-dimensional models include pump casing and fluid domains in pump are made by Pro/Engineer.The meshes of fluid domains in pump are made by ICEM-CFD.The steady flow field inside pump which include front pump cavity and back pump cavity is calculated numerically by CFX.The flow field and pump casing are singly fluid-solid coupling calculated by CFX and ANSYS Workbench.Every panel point's coordinate,stress and total deformation are exported by the post processing tool of ANSYS Workbench.The pump casing's stress distribution cloud pictures and the pump body's total deformation distribution cloud pictures in five working conditions of different flows are gotten.The maximum stress point's location and the maximum total deformation's location in five working conditions of different flows are comparisoned through table.The maximum stress,the minimum stress,the maximum strain,the minimum strain and the maximum total deformation are compared through table.The result show that the pump casing's stress distribution and strain distribution is scarcely changed in different flows.The maximum stress of the pump casing is less than 2Cr13's limit strength.Pump casing fit the strength requirement." @default.
