ABSTRACT

In order to reveal the structural characteristics of full-tubular submersible gate pump, correct its layout and improve the calculation theories of structural stress, this paper expounds the structure and layout of the submersible gate pump. Based on the Solid-Works design software platform and using 3D SimulationXpress finite element analysis software, the analysis and calculation of stress and strain of the inlet gate were carried out. The advantages of the full-tubular submersible pump are that it has a shorter body length, is lightweight, has a diversified arrangement as well as is easy to combine with the gate and lift. According to the 3D finite element calculation theory, the simulated condition is close to the actual working condition, while the calculation results of gate stress and deformation are superior to the graphic methods. In a low-head irrigation and drainage area, such as polders along the Yangtze River and low-lying lands along the Huaihe River and Huaibei Plain in China, a lot of drainage culverts and sluice gates will be rebuilt into full-tubular submersible gate pumps. As a result, the structural analysis and optimal design methodology can provide a reliable theoretical support and a guarantee for a safe and reliable operation of the project.
