Nowadays, most excavators use VOLVO VOLVO excavator diesel engines, because Volvo Volvo excavator diesel engines are significantly better than gasoline engines in terms of economy and power, especially the diesel engine torque is relatively large, which can better meet the work needs of excavators. As we all know, excavators need daily maintenance, diesel engine as the heart of the excavator, its daily maintenance becomes particularly important. So how should the diesel engine on the excavator be maintained? What do we need to pay attention to? Xiaobian will explain in detail the eight steps of daily maintenance of VOLVO Volvo excavator diesel engine.

First, check the oil level of the fuel tank to see if the amount of oil stored in the fuel tank is enough, if not, add enough oil level as needed.

When checking the fuel location, check the fuel tank for oil leakage. This step is more important because oil spills are money if there is a spill or trying to fix it in advance.

Second, check the oil level height to see whether the oil level height is within the specified range, if the oil is insufficient, it should be added in time.

If the oil is too much or too little, the engine should be checked at this time to see if there is oil leakage. This is also important, because once there is a problem with the oil, then there may be cylinder pulling, tile phenomenon, and then damage the engine.

Third, check the water level of the radiator to see if there is water shortage or antifreeze in the radiator, if there is water shortage, be sure to add it in time.

If the radiator water level is obviously too low, it must be checked in time for leaks. This project can not be saved, if the leak will cause the engine to appear "dry pot" followed by cylinder pulling, tile scratching and other damage to the engine phenomenon.

Fourth, see the diesel engine smoke situation, whether there is blue smoke, white smoke, black smoke phenomenon, monitor whether the engine has abnormal sound.

If the smoke is abnormal and the engine has abnormal noise, it must be checked and maintained in time to avoid affecting the progress of the next step.

Wiping VOLVO Volvo excavator diesel engine seems not important, but it is also necessary. Because wiping the engine is not only to ensure the cleanliness of the diesel engine, more importantly, it is conducive to finding the engine oil leakage, water leakage and other phenomena.

When wiping the surface of the diesel engine, it will also help us find some potential problems of the engine and solve them in advance, which is more conducive to reducing failures and extending the service life of the engine.

Six, look at the dashboard, see if there is a problem with the dashboard, see if the engine display on the dashboard is normal.

The dashboard is an important object for monitoring machines in daily work. Generally, it is also responsible for monitoring the engine. Therefore, we should try to be careful when checking the dashboard.

It is also necessary to check whether the connection and fixed parts of the engine are tight, because the machine will inevitably produce vibration during operation, and the vibration will loosen the screws of each connection and fixed part.

Once the screw is loose, the machine is weak, the body shakes, the machine parts are seriously damaged, and even cause unnecessary safety accidents. Therefore, this inspection is also very important.

8. Check the oil-water separator to see if it needs to be drained. If the water of the oil-water separator is not discharged in time, the nozzle will often fail, affecting the service life of the engine.

If the water or impurities in the diesel are not filtered out, it can wear and even pull the plunger parts in the nozzle. Fuel injector damage can cause the engine to accelerate unstable or weak acceleration, or emit black smoke.
