In some agricultural lands, orchards, and small construction projects, mechanical equipment can be seen everywhere. Small excavators are common agricultural machinery. It is inevitable that some minor faults will occur occasionally during use. What are the common faults of small excavators? How to deal with these faults?
1. Black smoke from exhaust
Orchard farmers often encounter black smoke from the exhaust pipe of the excavator when using small excavators to reclaim and loosen the soil. This may be caused by blockage of the heat sink or filter element, insufficient pressure in the engine cylinder, carbon deposits or damage to the turbocharger, and problems with the oil pump, injection pump or injector. The problem of black smoke from the exhaust pipe can be solved by checking the above problems one by one.
2. Unstable engine operation, overload, and stalling
The engine is the core equipment of the small excavator. Farmers find that the acceleration is weak when using small excavators. The above engine operation is unstable and causes stalling. This is caused by insufficient engine power. Therefore, when dealing with this type of fault, it is necessary to check the air filter element blockage, exhaust pipe blockage, oil supply, piston and cylinder liner wear, fuel system and other aspects. After solving the above problems, the problem of engine running causing the car to be stuck can be solved.
3. Large engine exhaust volume
Many people operating small excavators may find that the exhaust volume behind the excavator is large. This situation is mainly caused by the wear of the piston and piston ring and cylinder liner. Replacing the old piston can avoid the problem of excessive exhaust volume.
4. The engine cannot start
The failure of the engine to start is a headache for the owner of the excavator. If this problem occurs, it is necessary to check whether the power and voltage of the excavator battery are normal and whether there is any damage. If there is any damage, it needs to be repaired in time.
5. High oil consumption
Many excavator owners find that their excavators consume a lot of oil when using small excavators, and they run out of oil after a short time. This situation mainly occurs because the piston and cylinder liner are worn, or the floating oil seal of the exhaust gas turbocharger is damaged, causing the valve guide to split. Therefore, owners can check the above two possibilities one by one, and then replace the worn parts to solve the problem of high oil consumption of small excavators. Most small excavators are agricultural excavators. Many excavator owners use excavators when reclaiming and loosening the soil, so the frequency of use is very high. It is normal to have some minor faults. You only need to find the problem to solve it. Nantes small excavator has a wide range of applications, high cost performance, low fuel consumption, easy operation, and novices can quickly get started. It is an agricultural machinery equipment for reclaiming and loosening land and planting fruit trees.
