摘要
笔者以液压挖掘机为例,介绍了动力系统、液压系统及功率匹配等传统的节能技术,并分析了新型节能技术——振动掘削技术、负载口独立控制技术、二次调节静液传动技术及混合动力技术在挖掘机上的研究应用,指出混合动力技术是目前从原理和技术方面均可实现的新型节能技术,也是目前主机厂商研究的热点。
Taking the hydraulic excavator as the example, the paper introduced the traditional energy-saving technology related to power system, hydraulic system and power matching etc, and analyzed application of new-type energy-saving technology to the excavator such as vibrative cutting excavation technology, loading port independent control technology, secondary regulation hydrostatic transmission technology and hybrid power technology. In addition, it pointed out the hybrid power technology was the feasible new-type energysaving technology at present in principle and technology, and was the present study hot spot of manufactures.
