现代联合收割机上的升降、变速、转向等工作机构,大多采用液压操纵。因此,有人把液压系统称为联合收割机的“神经中枢”。但是,目前由于联合收割机液压系统的故障发生较多,明显地影响了收获作业的正常进行和收获效率的提高,给使用单位带来很多麻烦。笔者根据多年教学和推广工作的实际经验,对目前液压系统故障发生较多的原因及其对策,浅述如下,供同行们参考。 1.机手缺乏必要的培训,技术素质低这是液压系统故障发生较多的主要原因。由于目前多数县级农机培训部门不具备开设液压技术课的
Modern combine harvester on the lift, speed, steering and other agencies, mostly hydraulic control. Therefore, some people refer to the hydraulic system as the “nerve center” of the combine harvester. However, at present, due to the failure of the hydraulic system of the combine harvester, the normal operation of the harvesting operation and the improvement of the harvesting efficiency are obviously affected, which brings a lot of trouble to the user. The author based on years of teaching and promotion of practical experience, the current hydraulic system failure occurred more reasons and countermeasures, as described below for your colleagues for reference. 1. The lack of the necessary training of the hand machine, low technical quality This is the hydraulic system failure occurs more than the main reason. Due to the current majority of county agricultural training department does not have the hydraulic technology class
