农业机器液压系统故障的经验诊断需要维修人员具有一定的液压理论基础知识和丰富的实践经验。不仅如此,每当面对一种新机型液压系统的故障时,要认真阅读随机使用维护说明书,掌握系统的主要参数,如主安全阀的开启压力、流量等;熟悉系统的原理图,理解系统各元件符号的职能和相互关系,详细分析每个回路的功用;最好对每个液压元件的结构和工作原理也有所了
The empirical diagnosis of agricultural machinery hydraulic system failure requires maintenance personnel to have some basic knowledge of hydraulic theory and rich practical experience. Not only that, whenever faced with the failure of a new type of hydraulic system, we should carefully read the instructions for use of random maintenance, master the main parameters of the system, such as the main relief valve opening pressure, flow, etc .; Familiar with the system schematic diagram, understand System components symbols of the functions and interrelations, a detailed analysis of the function of each circuit; the best of each hydraulic components of the structure and working principle also have
