挖掘机节能液压控制系统分析与应用

Analysis and Application of Energy Saving Hydraulic Control System for Excavator

近年来,随着社会经济的快速发展,挖掘机、装载机等大型机械被广泛应用于各种基建行业、矿产行业中,随着机械化程度的提升,提高了工作效率,降低了经济成本,也加快了基建、矿产行业发展进程。但是,受限于工作环境的复杂性和机械本身设备的设计特点,机械发动机产生的功率并不能得到最大化输出,造成了能源的巨大浪费。通过对挖掘机的液压系统进行分析研究,探索通过改造液压系统提高利用率,达到节能的目的。

In recent years, with the rapid development of social economy, excavators, loaders and other large machinery are widely used in all kinds of infrastructure and mineral industries. With the improvement of the mechanization, the efficiency of work has been improved, the economic cost has been reduced, and the development process of the infrastructure and mineral industry has been speeded up. However, limited to the complexity of the working environment and the design characteristics of the machinery itself, the power produced by the mechanical engine can not be maximized, resulting in a huge waste of energy. In this paper, the hydraulic system of the excavator is analyzed and studied, and the purpose of energy saving is explored by improving the utilization ratio of the hydraulic system.
