新型三级压力双作用气－液增压装置（泵）原理设计与分析

摘要

一般的液压传动系统，约一半以上的输入功率转化为热能而损耗掉。因此，低能耗、高效率是衡量液压系统性能的一项重要指标。介绍一种基于节能、环保理念研发的，具有三级液体压力输出的双作用式气－液增压装置（泵）的工作原理，对其工作特性进行分析，给出主要参数的计算；并探讨了系统功率保全的原理和提高液压泵使用寿命的方法。%About half input power of general hydraulic power transmission system will be changed into heat energy and lost. Therefore low energy consumption with high efficiency is a very important target to evaluate a hydraulic system. The work principle of a new double⁃acting pneumatic⁃hydraulic pressure amplifier with three level pressure output was introduced which was designed based on the idea of energy saving and pro⁃environment. Its running characteristic was analyzed and its main parameters were calculated. A detail analysis on how to maintain power and increase use⁃life was made.
