液压挖掘机斗杆再生结构研究

Research on the Arm Regeneration Structure of Hydraulic Excavator

通过对现在市场主流液压元件的斗杆再生结构的研究,阐述了斗杆再生的结构及工作原理。斗杆再生是在挖掘机斗杆油缸回收时,将因工作装置势能影响下产生的斗杆油缸小腔的高压液压油再生到斗杆油缸大腔的一项技术,该技术的难点在于再生流量多少的控制及斗杆复合动作时的协调性。通过对不同斗杆再生结构的性能对比分析,并通过对挖掘机的测试验证,总结了不同再生结构的优缺点。斗杆再生技术可以回收能量,极大的提高了挖掘机的工作效率,并降低挖掘机能耗。

Based on the research on the arm regeneration of the current popular hydraulic elements in the market,explain the working structure and principle of the arm regeneration.Arm regeneration is a technology that when excavator take back the arm,regenerate the high pressure hydraulic oil produced by equipment working potential energy in the arm cylinder rod to the arm cylinder head.The difficulty of the arm regeneration is to control the regeneration flow and coordinate the arm compound action.According to compare and analyze different arm regeneration structures,and verify the testing on the excavator,summarize the advantage and weakness of different regeneration structures.Arm regeneration can recover energy,greatly improve the working efficiency of the excavator,and reduce the energy consumption of the excavator.
