液压系统是以液压油为工作介质 ,通过泵、油缸油马达的作用输出能量 ,这两部分在故障检测中既不象机械结构的直观 ,也不象电气结构的易子测量 ,故在故障检测中要在掌握液压技术的理论和液压元件和系统的结构原理基础上 ,进行判断和推理 ,现根据故障现象推断原因作一些经验介绍 Hydraulic system is a hydraulic oil as the working medium, through the pump, cylinder oil motor output energy, these two parts in the fault detection is neither intuitive mechanical structure, nor the electrical structure of the easy measurement, so fault detection In the master hydraulic theory and hydraulic components and systems based on the structure of the principle of judgment and reasoning, are based on the phenomenon of fault reasoning to make some experience introduction
