摘 要:介绍抓钢机、装载机等汽车设备在操作中如何根据排气管烟气颜色判断并排除发动机启动困难、动力不足等故障现象。炉料公司废钢
车间现有抓钢机 6 台、装载机一部,用于废钢、渣钢等业务的加工处理、外发等。在使用过程中经常遇到发动机出现启动困难等故障难题,经过
车间工技人员的研究,找到了一些好的诊断方法和处理措施,其中根据排气管烟气颜色判断并处理发动机故障得到了普遍使用,下面就浅谈一下
如何根据烟气颜色判断和排除故障。
Abstract: grasping steel machine, loaders and other automotive equipment how to judge and exclude difficult to start the engine exhaust
pipe smoke color operation, lack of motivation and other symptoms. Company workshop existing charge scrap steel grab six, a loader for
processing scrap steel slag and other business, outsourcing and the like. In the course of frequently encountered engine problems such as
failure appears difficult to start, through research workshop technicians work to find some good diagnostic methods and treatment measures,
according to the exhaust pipe and smoke color judging process has been widely engine failure use of the following on how to determine the
color based onsmokeand troubleshooting.
