In order to improve and optimize the structure and performance of the submersible diaphragm pump, make the pump work more efficient and stable, and reduce the energy loss and noise, take the single-turn crankshaft of the submersible diaphragm pump as the research object, analyze the force of the single-turn crankshaft, establish a three-dimensional model of the single-turn crankshaft, and parameterize the key design dimensions, find the force change of the single-turn crankshaft by changing the size, and bring the changed value into the software for further analysis, and obtain the influence relationship between the key size parameters of the single-turn crankshaft on performance and stability. Finally, the single-turn crankshaft is optimized by finite element software. The results show that the force of the single-turn crankshaft can be changed through parameter optimization, which can reduce the maximum stress of the single-turn crankshaft and improve the overall safety factor, and the maximum stress of the optimized single-turn crankshaft is reduced by 16.28%, the total deformation is reduced by 15.81%, and the optimized state is more stable, and the bearing capacity and life are improved. It is believed that the parameter optimization of finite elements is obviously helpful for the improvement of single-turn crankshaft.
