近年来随着时代的进步,农业生产的现代化程度越来越高,这带来的就是农业机械普及率的提高。本文结合实际工作和研究中的经验,首先论述联合收割机中液压系统齿轮泵部位的工作原理,之后从这个部件的使用和维修两个方面展开论述,希望可以让使用者对于该农用机械进行更好的使用。 In recent years, with the progress of the times, the degree of modernization of agricultural production is getting higher and higher, which brings about an increase in the penetration rate of agricultural machinery. Based on the actual work and the experience in the research, this paper first discusses the working principle of gear pump parts of the hydraulic system in the combine harvester, and then discusses the use and maintenance of this part, hoping to make the user more suitable for the farm machinery Good use.
