液压挖掘机的节能技术研究

The Investigation of Energy-saving Technology of Hydraulic Excavators

液压挖掘机作为最常用而又耗能巨大的工程机械,其有效能量利用率仅占20%左右,巨大的能量损耗不仅造成了能量浪费而且污染了周围环境,因而开展挖掘机械领域的节能技术研究很有必要。本文全面梳理了挖掘机节能技术研究的现状,而且提出了未来节能技术发展的针对性建议。

Hydraulic excavator is a enormous energy-dissipating engineering machine in common use,but effective energy availability is as little as about20%. The huge energy consumption is not only energy-wasting but also environment-polluting,so the research about energy-saving technology of hydraulic excavators is awfully necessary. The investigation situation of energy-saving technology of hydraulic excavator is hackled and some serviceable suggestions are also given in this article.
