Inventory of common faults of mini excavators
Now the busy farming season is not as good as it was in the past, the use of labor-saving tools is becoming more and more popular, and mechanical equipment can be seen everywhere in the farmland and orchard greenhouses, and small excavators are the most common agricultural machinery in rural areas. Small glitches are unavoidable, how should these glitches be dealt with?
Unstable and overloaded engine operation
The engine is the core equipment of the crawler excavator. When using the small excavator, it is found that the acceleration is weak and the engine operation is unstable, which leads to the stalling of the car. This situation is caused by the lack of engine power. Therefore, when dealing with such faults, it is necessary to detect the blockage of the air filter element, the blockage of the exhaust pipe, the oil supply, the wear of the piston and the cylinder liner, and the fuel system. solved
High oil consumption
When using a Compact Crawler Excavator, I found that my excavator consumes a lot of oil, and it doesn't take a long time to run out of oil. This situation occurs mainly because the piston and cylinder liner wear and tear, or the valve guide may be damaged due to the damage of the exhaust turbocharger floating oil seal. Splitting, you can check the above two possibilities, and then replace the worn parts, you can solve the problem of large oil consumption of small excavators
black smoke from the exhaust
When using a small excavator to reclaim the soil, it is often encountered that the exhaust pipe of the excavator emits black smoke. This situation may be due to the blockage of the radiator or filter element, the insufficient pressure in the engine cylinder, and the turbo booster. There is carbon buildup or damage, and there is a problem with the fuel transfer pump, fuel injection pump, or fuel injector.
