Explanation:
The engine oil of excavator is one of the most serious faults in the failure of the excavator engine. In the excavator, the oil consumption of the excavator is found to be higher than that of the same type of excavator, and the blue black smoke is accompanied by the phenomenon of blue black smoke in the operation, and the oil is burning the oil.
Fault classification:
1. The oil consumption of the excavator is abnormally increased, and the oil consumption is much more.
2, the blue and black smoke of the lower exhaust;
The reason for the oil burning of the excavator is:
1. In the excavator, the blue and black smoke is discharged from the bottom of the excavator, and the consumption of the oil is more than usual. It shows that the engine oil is excavate, which may be caused by the wear of the piston ring, the large clearance of the valve, the large clearance of the valve tube and the error of the piston installation.
2, the clearance between the cylinder liner and the piston is too large, or the piston oil ring dies or breaks.
3, if the phenomenon of burning oil is accompanied by the phenomenon of lower exhaust and dripping oil, it is likely that the piston ring wear is serious or broken.
4, the engine oil, if the lower exhaust is not very serious, may be the turbocharging seal is not strict, at this time, it is recommended to remove the turbocharged ends of the pipe to see if there is any oil, if the oil shows the turbocharger fault.
5, in addition, the bad sealing of engine valve seal will also cause the phenomenon of oil burning.
6, the oil is much more.
The common treatment method for the oil burning of the excavator is:
1, check the oil is too much.
2. Check the turbocharged turbine and release the hose at both ends of the intake and exhaust. Normal should be dry. If oil is found, there may be a problem with the turbine that causes the oil from the turbine to the exhaust pipe.
3, pay attention to the exhaust pipe when you start burning in the morning. If black smoke and clear oil smell, it may be the turbine fumes.
4, check the exhaust pipe of engine exhaust weight is not heavy, normally should see the light smoke, if the exhaust is very heavy, serious or even dripping oil, it should repair the engine.
5, in addition, turbine oil generally has little oil, and the exhaust pipe should be checked.
