How to reduce the wear of excavator parts


Excavator is a kind of heavy construction machinery, mainly can be used in building construction, earthmoving works and other land development projects. Small excavators can also carry out some household projects, such as orchard construction, indoor construction and other small engineering projects. Lu Yu Machinery is a professional construction machinery manufacturer, with many years of construction machinery manufacturing experience. In particular, small excavators, based on continuous innovation and improvement, have created high-quality small excavators. Excavator products can bring us a lot of convenience in daily use, but excessive use will make the various parts of the excavator begin to wear, so how can we reduce the wear of the excavator parts in daily use?

1. Regular maintenance and inspection: Specify and implement a regular maintenance plan as recommended by the excavator manufacturer, which will ensure that the various systems and components of the excavator are in good working condition and reduce wear and failure. Check the lubrication system to ensure that the quality and level of lubricating oil meet the requirements. Change the lubricating oil and filter regularly to maintain the normal operation of the lubrication system. Check the hydraulic system, including checking the quality and level of hydraulic oil, checking whether there is leakage of pipelines and connectors, etc., to ensure that the hydraulic system works properly to avoid excessive wear. Check the transmission system, including tracks, chains, gears, etc. Ensure that their tension and the degree of wear to the teeth are within the normal range, and adjust and replace them in time if problems are found.

2. Use the right lubricant: According to the recommendations of the excavator manufacturer, choose the appropriate lubricant for different parts and systems. Ensure the quality and performance of the lubricant meet the requirements to provide good lubrication and protection. Follow the manufacturer's recommendations and guidelines to change the lubricant regularly. Outdated lubricants can lose their performance, leading to an increase in wear and breakdowns.

3. Standardized operation and training: Train excavator operators to ensure that they understand the correct operation methods and skills. For example, avoid suddenly starting or stopping the excavator, avoiding sharp turns and sudden changes of direction. Do not overload the excavator, overload will increase the load of various parts, resulting in excessive wear and damage. Be sure to understand the rated load and working limits of the excavator and operate within its limits.

4. Regular cleaning: Clean the external and internal parts of the excavator regularly to remove dust, mud and debris. Accumulated dirt can cause wear and tear on components and affect the effectiveness of lubrication and cooling systems. Pay special attention to clean air filters and radiators. The air filter should be replaced regularly to avoid dust and particles entering the engine. The radiator should be kept clean to ensure normal heat dissipation.

5. Avoid overuse: Long-term continuous use will lead to overheating and wear of various parts of the excavator, and give the excavator appropriate rest time to allow parts to cool and recover.

6. Regular inspection and replacement of worn parts: regularly check the key parts of the excavator, such as tracks, chains, gears, hydraulic cylinders, etc. If wear, cracks or other damage is found, it should be repaired or replaced in time. Follow manufacturer's recommendations and regulations to replace worn parts regularly. For example, the track and chain need to be replaced when the wear is severe to maintain the normal operation of the excavator and reduce the wear of other components.

7. Adjust the working environment: Try to avoid using the excavator in harsh working conditions, such as muddy areas or hard rock surfaces, which will increase the load and wear of the excavator components. If it cannot be avoided, appropriate protective measures, such as the use of bedding or protective plates, can be considered to reduce the risk of wear and damage.

When we find that some parts of the excavator start to wear out during routine inspection of the excavator, we can take the following remedial measures.

1. Timely repair or replacement of worn parts: Once the worn parts are found, timely measures should be taken to repair or replace them. Delayed repair may cause wear problems to expand, further affecting the normal operation of other components. Select the appropriate repair or replacement method according to the recommendations and regulations of the excavator manufacturer. You can refer to the maintenance manual provided by the manufacturer or consult a professional maintenance personnel.

2. Choose high-quality replacement parts: When it comes to replacing worn parts, it is very important to choose high-quality replacement parts. Ensure use of original or approved alternatives that meet specifications and quality standards. Quality replacement parts usually have better wear resistance and durability, which can provide a longer service life and better performance.

3. Adjust the operation method and environment: If the parts are found to be worn severely or frequently, it may be necessary to re-evaluate the operation method and working environment. Train operators to ensure they use excavators properly and comply with operating restrictions and recommendations. Adjust the working environment to minimize the impact of load and wear on components. For example, improving ground conditions, avoiding overloading and overuse.

4. Regular maintenance and maintenance: Strengthen regular maintenance and maintenance work to ensure that the various parts of the excavator are in good working condition. Replace lubricants, filters and other consumables regularly to ensure proper lubrication and protection systems to reduce wear and tear. Clean and maintain the external and internal parts of the excavator to remove dust and debris and prevent further wear and damage.

If one part of the excavator has begun to wear, it may have the following bad effects on other parts.

1. Cascading wear: The presence of a worn component may cause cascading wear of other adjacent components. For example, a worn chain gear may cause further wear on the chain, or a worn gear may cause damage to other parts of the drive system. This cascading wear will accelerate the wear and failure of the entire system.

2. Load increase: A worn part may cause other parts to bear a greater load. For example, a worn track may increase the load on the hydraulic system and drive system, causing the hydraulic pump and motor to overwork, which in turn accelerates their wear.

3. Functional limitations: The functional limitations of worn parts may affect the overall performance and efficiency of the excavator. For example, a worn hydraulic cylinder may cause the excavator's arms and buckets to move slower, or a worn track may reduce the excavator's traction and driving ability.

4. Increased risk of failure: The presence of worn parts increases the risk of failure of other parts. Worn parts can cause abnormal friction, overheating and vibration, which can affect the reliability and stability of the entire system, and can lead to more serious failures and downtime if worn parts are not repaired or replaced in a timely manner.

5. Increased maintenance costs: If a part is heavily worn or damaged, more repair work and higher maintenance costs may be required. Worn parts can affect the working condition and performance of other parts, resulting in the need to repair or replace multiple parts at the same time.

Therefore, when one part of the excavator wears out, it is very important to take remedial measures in time to prevent the wear problem from expanding and affecting other parts. Regular inspection, maintenance and repair of worn parts can reduce the adverse impact on other parts, extend the service life of the excavator, and reduce maintenance costs.
