Modal Simulation Analysis and Test Research of Horizontal Pump
Natural frequency is one of the important factors to evaluate the stability of centrifugal pump.The modal analysis and test method of single-stage end-suction horizontal pump are studied in this paper.The finite element model of horizontal pump is established,and the natural frequency and vibration mode of horizontal pump are obtained by taking into account the same boundary conditions as the test state.The results show that the maximum error of the horizontal natural frequency simulation and test is 5.1%,and the maximum error of the vertical natural frequency simulation and test is 16.9%.The simulation and test results of the horizontal pump are consistent.The simulation analysis method can be used to guide the design and optimization of the centrifugal pump modal performance.
