民用飞机变量泵排量控制系统原理分析

Principle Analysis of Variable Displacement Control System of Axial Piston Pump in Civil Aircraft

民用飞机液压系统采用恒压式变量泵作为系统的动力元件。针对某型民用飞机选用的两种恒压变量泵,详细分析了这两种泵的控制系统结构及泵在不同工作模式下工作时排量控制系统的工作原理。

Constant pressure variable displacement pumps are applied as power components for hydraulic systems in civil aircrafts. For two kinds of constant pressure variable displacement pump used in certain civil aircraft, this paper analyzes their control system configuration. And the working principles of displacement control system in different working modes for these two pumps are also given.
