恒压轴向柱塞变量泵系统的无级调节控制研究

The research of a constant pressure variable capacity pump system by parameters controlled sleeplessly

恒压轴向柱塞变量泵由于输出功率大、工况合理、能量利用率高 ,因而成为许多液压控制系统的首选动力源。通过对其变量机构改造 ,研究了一种基于高速开关阀压力控制系统构成的新型电液伺服变量机构 ,实现了对恒压轴向柱塞变量泵输出压力的无级控制。

Because of the output macro energy,justified working condition and high capacity utilization,a constant pressure variable capacity pump system becomes prime dynamic resource. After remolding its variable capacity machinery, the author researches a new variable capactiy servo hydraulci organization base on high speed on off valve pressure control system and achieve the output pressure control of the constant pressure variable capacity pump.
