丹尼逊型恒压变量轴向柱塞泵是国外最近出现的一种低噪音类型泵。它利用斜盘具有固定的横向倾角、配流盘同时开有减震槽的方法,使恒压变量轴向柱塞泵在全工况调节范围内完全消除液压配流冲击,从而使泵运转平稳、嗓音低。本文对该泵的抗噪音工作原理、性能特点、设计计算过程以及主要设计参数的选择方法作了研究。
Denison constant pressure variable axial piston pump is a recent low noise type of pump abroad. It utilizes a fixed horizontal inclination of the swash plate and a damping groove at the same time in the plate, so that the constant pressure variable displacement axial piston pump completely eliminates the impact of the hydraulic pressure distribution in the adjustment range of the whole working condition so that the pump runs smoothly and the voice low. In this paper, the noise of the pump working principle, performance characteristics, design and calculation process and the choice of the main design parameters were studied.
