Daily maintenance plays a crucial role in extending the service life of excavators. You can take the following measures to perform daily maintenance on excavators:
1.Engine maintenance:
Regularly inspect the engine oil, coolant, diesel, etc. to ensure they are at normal levels.
Regularly replace the engine oil and filter element based on the actual usage of the excavator.
Regularly inspect key components such as the air filter, fuel filter, and fuel injector of the engine to ensure their normal operation.
2.Hydraulic system maintenance:
Regularly check the oil level and quality of hydraulic oil to ensure that the oil level is within the normal range and the oil quality is clean.
Regularly clean the hydraulic oil tank and filter, and replace the filter element.
Inspect key components such as hydraulic pumps, distribution valves, and hydraulic pipelines to ensure they are working properly.
3.Electrical system maintenance:
Regularly inspect the key components of the excavator, such as batteries, generators, cables, and connectors, to ensure their normal operation.
Regularly replace the battery electrolyte to ensure the performance of the battery.
4.Maintenance of rotary reducer:
Regularly check the oil level and quality of the rotary reducer to ensure that the oil level is within the normal range and the oil quality is clean.
Regularly replace the reducer oil.
5.Track and tire maintenance:
Regularly check the wear of the tracks and tires, and if severe wear is found, replace it in a timely manner.
6.Lubrication and maintenance:
Regularly lubricate various lubrication points of the excavator, such as gears, bearings, chains, slides, etc.
In addition, there are some maintenance points that need to be noted:
1.Avoid corrosion: The working environment of construction machinery is often outdoors, and measures should be taken to prevent wind, frost, rain, and snow erosion, as well as chemical substances entering the machinery through gaps and external channels to corrode internal parts.
2.Ensure normal working load: The size and nature of excavator working load are closely related to equipment wear and tear, and the normal working load of the excavator should be ensured.
3.Reduce the impact of impurities: During equipment operation, air and self generated impurities should be reduced from entering the mechanical interior to avoid scratching the surface of accessories, damaging the lubricating oil film, causing the temperature of parts to rise and the lubricating oil to deteriorate.
4.Ensure normal operating temperature: During the operation process, the optimal temperature of each component has a certain range. Exceeding or falling below the appropriate range will accelerate component wear, cause lubricant deterioration, and cause changes in material properties.
In addition, the maintenance cycle of excavators is generally 200 to 500 hours for minor maintenance, and every 500 to 1000 hours for major maintenance. The specific maintenance cycle may vary slightly depending on the usage of the excavator, and should be adjusted according to the actual situation to ensure the normal operation of the machine.
In short, the maintenance of excavators is crucial to ensure their normal operation and extend their service life. It is recommended to follow the maintenance manual and recommendations provided by the manufacturer for regular maintenance, and make appropriate adjustments based on actual usage. At the same time, during maintenance, make sure to shut down and follow safety operating procedures to ensure personnel safety.
