    济南装载机配件出现故障应该如何检查?
    发布时间:2014-6-9 10:22:30    浏览:217次

    济南装载机配件故障因素是相当复杂的,有的故障其可能的原因竟多达几十项。例如装载机牵引力不足,产生的原因有10多种,可能涉及到发动机、变矩器、动力换挡变速器、液压操纵系统、驱动桥、制动系统等等,这些因素有时是单一的,有时是综合交替的起作用,因而要做到准确而迅速的诊断出故障的原因是比较困难的。这就要求诊断人员必须熟悉装载机整机、各系统、各配件的构造及其工作原理,还要有一定的时间经验。在有条件情况下,尽量应用专用活自制的检测仪器活设备进行诊断。

    济南装载机配件的常见诊断方法大致可分为两大类:一是直观诊断,即通??抗鄄旌透芯跻约凹虻スぞ?,采用个别症状放大或暂时隐蔽的方法进行诊断;二是客观诊断法,即仪具诊断法,采用检测设备,仪器和专用工具,通过检测装载机的结构参数和工作参数来确定故障。实际上,这两种方法经常是综合交替应用的。
           
    关于故障诊断的具体方法,lol竞猜平台app总结6个字:问、听、看、嗅、摸、试。
           
    问,就是询问,除驾驶员诊断自己所使用的济南装载机配件故障外,任何人在诊断前,必先问明情况,如济南装载机作业的累积时间,近期保养情况,故障发生前有何预兆,是突变还是渐变等。
    In addition to the driver's own fault diagnosis Jinan loader accessories used by, any person before diagnosis, we must first ask the circumstances, such as cumulative time Jinan loader operations, maintenance recent case, before a failure occurs harbinger of what is mutated or gradients.
    听,就是凭听觉判断装载机有无异常响声。      
    With hearing to determine whether the abnormal sound loader.
    看,就是观察,例如观察发动机的排烟情况,在结合其他情况分析,就可以判断发动机的工作状况。
    Observe the engine exhaust, and in combination with other analysis, you can determine the operating condition of the engine.       
    嗅,就是凭在装载机运行中发出的某些特殊的气味,来判断故障之所在。这对于诊断电系线路,摩擦衬套等处的故障是简单有效的。
    With some special odor emitted during loader operation, to determine the fault lies. This diagnostic Electrical lines, friction bushings, etc. The failure is simple and effective.       
    摸,就是用手触试可能产生故障部位的温度、振动情况,从而判断出配合副有无咬住,轴承是否过紧等。
    Test temperature may malfunction hand touch parts of the vibration, in order to determine the presence or absence of the sub bite with bearing too tight like.       
    试,就是试验验证。如诊断人员可亲自试车去体验故障的部位;可用单缸停供油来排定发动机某一缸工作又缺陷;可用更换零件或配件的方法来证实故障的部位。
    Diagnostic test personnel to experience in person the fault location; available single-cylinder engine to stop oil supply to schedule a cylinder work was defective; replacement parts or accessories available methods to prove the fault of the site.
