液压挖掘机有着质量高、效率高等优点,其在建设施工中有着广泛的应用,挖掘机的主要工作就是挖掘土壤,其挖掘任务由工作装置来完成,挖掘机一般在户外工作,因此经常面临复杂的工作环境,这就对其液压系统的设计提出了更高的要求,基于以上,本文简要研究了液压挖掘机工作装置与液压系统的设计。 Hydraulic excavators have the advantages of high quality and high efficiency. They are widely used in construction and construction. The main work of excavators is excavation of the soil. The excavation tasks are completed by the working equipment. The excavators are usually outdoors and are often complicated Of the working environment, which put forward higher requirements for the design of hydraulic system. Based on the above, this paper briefly studies the hydraulic excavator working device and hydraulic system design.
