| Abstract: | In this paper, the frequency spectrum and vibration characteristics of a certain type of marine five-screw pump are analyzed to find out the main sources of vibration and noise. By improving the area of inlet runner and the existing processing technology of screw was studied and optimized. After the improvement, the prototype wad mad. The feasibility of the improved method and the expected effect of vibration reduction and noise reduction are further verified through experimental comparison and analysis. |
