等流量凸轮式轴向柱塞泵设计与特性分析

针对鱼雷斜盘式轴向柱塞泵的振动噪声问题,设计了凸轮式轴向柱塞泵这一新型结构的鱼雷燃料泵。通过分析其瞬态流量建立了等流量变分方程,求解方程得到凸轮型线。分析其动力学,得出柱塞与凸轮之间无硬冲击或软冲击,且柱塞组可以达到惯性力平衡和惯性力矩平衡。凸轮式轴向柱塞泵的以上特性从原理上保证了其具有低振动噪声水平,可用作未来的鱼雷燃料泵。

Design and Analysis on Cam Axial Piston Pump with Constant Flow

To reduce vibration noise of the swashplate axial piston pump of a torpedo, a novel curved cam axial piston pump is designed. Constant flow variation equation is derived through analysis of transient flow. The cam profile lines are obtained by solving the equation. Kinetic analysis of the cam axial piston pump indicates that there is no hard shock or soft shock between the piston and the cam, and the piston group can gain both balances of inertia force and inertia moment. These characteristics of the proposed curved cam axial piston pump can ensure its low vibration noise level.This curved cam axial piston pump may be applied to future torpedo as a fuel pump.
