| Abstract: | In this paper, the main noise source and frequency spectrum and noise characteristic are analyzed and the effect of blower structure and pneumatic parameter on pneumatic noise are discussed. Morever,the practical noise control ways now being used in our country over centrifugal and axial-flow blower are sorted,and based on a colllection of the latest information, the study tendenly and mehods are introduced blriefly. This essay can be used as a reference for engineering and technical person who are engaged in mechanical drawing and manufacturing. |
