挖掘机烧机油原因及故障处理

日期:2022-09-17   来源:http://www.dybocheng.com
加长臂挖掘机发动机烧机油故障现象是一种常见的挖掘机故障之一,在这里小编给大家分析一下挖掘机发动机烧机油的故障原因,同时给出维修解决办法,希望对大家处理这类故障有所帮助。
The engine oil burning fault of the extended boom excavator is one of the common excavator faults. Here, I will analyze the causes of the engine oil burning fault of the excavator and provide maintenance solutions. I hope it will be helpful for you to deal with this kind of fault.
挖掘机烧机油原因如下:
The reasons for the excavator burning oil are as follows:
1、挖机作业中下排气排蓝黑色的烟,且观察机油消耗也比平时多,说明挖机烧机油,可能是活塞环磨损、气门间隙大、气门导管间隙大、活塞安装错误等原因造成。
1. The blue black smoke is discharged from the lower exhaust during the excavator operation, and the oil consumption is more than usual. This indicates that the excavator burns oil, which may be caused by piston ring wear, large valve clearance, large valve guide clearance, incorrect piston installation, etc.
2、缸套和活塞的间隙过大,或者是活塞油环卡死或断裂。
2. The clearance between the cylinder liner and the piston is too large, or the piston oil ring is stuck or broken.
3、如果烧机油现象发生后伴随有下排气滴油现象,很可能是活塞环磨损严重或者断裂造成。
3. If the phenomenon of oil burning is accompanied by oil dripping from the exhaust gas, it is likely that the piston ring is seriously worn or broken.
4、烧机油,如果下排气不是很严重,可能是涡轮增压密封不严造成,此时建议将涡轮增压两端管子拆下看看有没有机油,如果有机油说明涡轮增压器故障。
4. Oil burning. If the lower exhaust is not very serious, it may be caused by the poor sealing of the turbocharger. At this time, it is recommended to remove the pipes at both ends of the turbocharger to see if there is any oil. If there is any oil, it indicates that the turbocharger is faulty.
5、另外加长臂挖掘机发动机气门油封密封不良,也会造成挖掘机烧机油现象。
5. In addition, the poor sealing of the engine valve oil seal of the extended boom excavator will also cause the excavator to burn oil.
6、机油加多了。
6. There is too much oil.
7、挖掘机使用过低粘度的机油。
7. The excavator uses oil with low viscosity.
加长臂挖掘机
常见处理方式:
Common handling methods:
1、先检查加长臂挖掘机的机油量,是否已超过机油标尺的上限。
1. First, check whether the oil volume of the extended boom excavator has exceeded the upper limit of the oil dipstick.
2、检查增压涡轮,把进气和排气两端胶管松开看,正常应是干的。发现有油可能是涡轮有问题导致机油从涡轮到排气管了。
2. Check the turbocharged turbine and loosen the rubber hoses at both ends of the intake and exhaust. It should be dry normally. It is found that there is oil. It may be that there is something wrong with the turbine, causing the oil to flow from the turbine to the exhaust pipe.
3、早上刚打燃时注意一下排气管,如果黑色浓烟并有清晰机油味就可能是涡轮窜油了。
3. Pay attention to the exhaust pipe when starting the ignition in the morning. If there is black smoke and clear oil smell, it may be that the turbine has oil leakage.
4、检查发动机废气管废气重不重,正常应多看见淡淡的烟,如果废气很重,严重的甚至滴油,就该修发动机了。
4. Check whether the exhaust gas in the engine exhaust pipe is heavy. Normally, light smoke should be seen. If the exhaust gas is heavy, serious or even drips oil, it is time to repair the engine.
5、另外,涡轮窜油一般机油少得不厉害,应检查排气管。
5. In addition, the turbine oil leakage is generally not much, so the exhaust pipe should be checked.
6、应正确的选用机油,根据挖掘机要求选购对应粘度、型号的机油,且随着季节变化或不同地域合理选用机油;柴油机须采用柴油机油,不可用汽油机替代,不同品牌、不同型号的机油不可混用!
6. The engine oil shall be selected correctly. The engine oil with the corresponding viscosity and model shall be selected according to the requirements of the excavator, and the engine oil shall be selected reasonably according to the seasonal changes or different regions; Diesel engine oil must be used for diesel engine, which cannot be replaced by gasoline engine. Different brands and models of engine oil cannot be mixed!
在挖掘机的日常使用中我们应该怎样来避免类似故障的发生呢?除了应该按照规定时间对挖掘机进行检修保养外,同时还应该按照正确的操作方法使用挖掘机。更多有关事项就来我们网站http://www.dybocheng.com咨询吧!
How can we avoid similar failures in the daily use of excavators? In addition to the maintenance of the excavator according to the specified time, the excavator should also be used according to the correct operation method.
