Why excavators often lack oil? May be the reason ...
Excavator engine burning oil refers to the fact that the oil loss during the excavator operation is higher than that of the same type and the same type of excavator oil, and the operation is accompanied by the phenomenon of blue and black smoke. Excavator engine burning oil is one of the more serious faults in the engine failure of excavator. Let's understand the reasons and solutions for the burning of excavator oil: The breakdown of excavator burning oil failure classification: a large amount of blue smoke is emitted at startup; a large amount of blue smoke is emitted when refueling; A large amount of blue smoke is emitted from the oil filling port; the consumption exceeds the normal requirement.
Reasons for excavator engine burning oil
1.The lower exhaust exhausts blue and black smoke during excavator operation, and observes that the oil consumption is greater than usual, which indicates that the excavator burns engine oil, which may be caused by worn piston rings, large valve clearance, large valve guide clearance, and incorrect piston installation Cause.
2. The gap between the cylinder liner and the piston is too large, or the piston oil ring is stuck or broken.
3. If the phenomenon of engine burning oil is accompanied by oil dripping from the exhaust gas, it is likely that the piston ring is severely worn or broken.
4. Burn the engine oil. If the lower exhaust is not serious, it may be caused by the tight seal of the turbocharger. At this time, it is recommended to remove the pipes at both ends of the turbocharger to see if there is oil. .
5. In addition, the engine valve oil seal is not well sealed, which will also cause the excavator to burn oil.
6. Add more oil.
7. The excavator uses too low viscosity oil.
Common processing methods
1. First check whether the oil quantity of the excavator has exceeded the upper limit of the oil gauge.
2. Check the supercharged turbine, loosen the hoses at both ends of the intake and exhaust, it should be dry normally. If oil is found, there may be a problem with the turbine, causing the oil from the turbine to the exhaust pipe.
3. Pay attention to the exhaust pipe when it is just lit in the morning. If the thick black smoke and clear smell of the oil may be the turbine oil channeling.
4. Check that the exhaust gas from the engine exhaust pipe is not heavy. Normally, you should see the most faint smoke. If the exhaust gas is heavy, serious or even dripping oil, it is time to repair the engine.
5. In addition, the turbine oil channeling is generally not too much, and the exhaust pipe should be inspected.
6. The engine oil should be selected correctly, and the oil of the corresponding viscosity and model should be selected according to the requirements of the excavator, and the oil should be selected reasonably as the season changes or in different regions. Do not mix engine oils.
