降低柱塞泵噪声问题的研究

本文主要分析了斜盘型轴向柱塞泵产生噪声的机理，指出了降低噪声的设计着眼点，推导了低噪声型配流盘阻尼孔及三角槽计算公式，并通过计算机求解了柱塞腔内液体压力的变化曲线。最后通过试验证实了设计方法的正确性。

RESEARCH ON THE PROBLEM OF REDUCING THE NOISE OF PISTON PUMP

This paper is going to analyse mainly the inherent theory on how the swash plate type piston pump does produce noise, Point out the focus of designing to reduce the noise, Find out the formula for calculating the orifice and triangular groove of reducing noise valve plate, And calculate the changing curve of liquid pressure in piston chamber by computer, And finally confirm the correctness of the designing method through experiments.
