Abstract To study the vibration characteristics of the high flow self-priming centrifugal pump shaft and crank-shaft, based on ANSYS finite element analysis software. The high flow self-priming centrifugal pump shaft and crank-shaft modal characteristics were studied, the shaft and crank-shaft front 5-order vibration mode and natural frequency diagram of the high flow self-priming centrifugal pump were analyzed, and its natural frequency corresponding to the critical speed was studied. It is found that a high flow self-priming centrifugal pump shaft in the support spacing and forms mainly reflects the twisted vibration, and the fourth-order torsional deformation occurs two times, showing the symmetrical distribution change. At the same time, the design speed of the high flow of self-priming centrifugal pump shaft is 2 200 r/min, while the minimum critical speed of the high flow self-priming centrifugal pump shaft is 2 848.07 r/min, far higher than the actual speed of 2 200.00 r/min, thereby avoiding the possibility of resonance.The results show that the reasonable structure design can effectively avoid the high flow self-priming centrifugal pump shaft and crank-shaft resonance. Vibration mode diagrams and animation obtained by modal analysis, clearly show the dynamic characteristics of the high flow self-priming centrifugal pump shaft and crank-shaft, which provides an important theoretical basis for the safe operation of the system, vibration analysis and optimization design of the structure.
