某转子式机油泵噪声分析及改进

Analysis and Improvement about One Rotor Oil Pump

机油泵是发动机润滑系统的重要组成部分,它的主要作用是保证发动机在各种转速下,都能供给足够数量的机油,以维持足够的机油压力,保证发动机的润滑。在机油泵运转时,因相关部件存在间隙,在旋转啮合时,会产生不同程度的碰撞,从而产生较大的振动和噪声。

Oil pump is the important component in lubrication system, it＇ s main function is that supply enough oil to maintain enough oil pressure which ensure engine＇ s lubrication under all speed condition. While oil pump working, with the interval in related component and hitting in rotary mesh, it will cause enormous vibrate and noise.
