5 factors affecting the service life of excavators
上海华诚二手挖掘机市场 / 2024-09-26There are many types of excavator work, and the service life of different excavator equipment in different environments is very different. This issue mainly interprets the four external factors that induce the service life of excavators. Theoretically, the normal service life of excavators is 10-15 years. The failure rate will increase with the aging of equipment in 15-20 years. There are still a large number of old excavators in the global engineering machinery industry. However, considering factors such as emissions, performance, and failure rate, the cost of use is not cheap, but the maintenance cost is low, the price is cheap, and the performance can meet daily use, which leads to a large number of users still prefer to choose it.
1. Working environment
There are huge differences in the damage of excavators to equipment in different environments. The main cause is the wear of metal parts inside the engine and hydraulic pump caused by dust and sand infiltration into the filter to pollute the hydraulic oil and engine oil. The corrosive environment is mainly caused by the metal corrosion caused by the working type of salt water and chemicals, which causes gaps in the connecting parts of the excavator. Working at extremely high and extremely low temperatures will also cause huge burdens and pressures on the core assembly inside the excavator.
2. Maintenance
This is an important factor affecting the service life of the excavator. In harsh environments and even under load, by shortening the maintenance cycle, regularly replacing grease, and replacing air filters, oil filters, and hydraulic oil filters to reduce the penetration of pollutants into the core assembly, the service life is greatly extended. For leakage, wear and other conditions, timely detection and timely replacement are carried out to reduce the wear of metal parts.
3. Operator level
The reason why excavators have huge differences in the hands of different operators is that the operator's frequent load, rapid steering, emergency stop and start during operation, as well as operating errors in the excavator work increase the metal fatigue of the excavator and the wrong operation method increases the working load pressure of the equipment, causing equipment pressure.
4. Vibration and shock
When working in mines and hard materials, the installation of destructive auxiliary tools such as hydraulic crushing or hydraulic pliers on the excavator can improve work efficiency, but the burden on the excavator hydraulic pump will be greatly increased, especially the vibration shock of hydraulic crushing puts great pressure on the hydraulic system, and the use of hydraulic crushing will cause a lot of dust, vibration shock, and the dipper rod, boom, and connecting parts will cause huge wear with long-term work. However, the benefits of hydraulic crushing far exceed those of ordinary earthwork.
5. Quality and brand
In addition to considering configuration and performance, when purchasing an excavator, it is necessary to pay attention to the detailed information provided by the manufacturer. The price difference between a new excavator of the same model can be more than 40%. Such a large price difference will result in a certain error in quality. In addition to the power and hydraulic systems, the materials and manufacturing process of the excavator equipment and the performance adjustment of the whole machine can play the performance and provide stability. In some details that we ignore, such as hydraulic pipelines, chassis materials, track strength, metal wear resistance, etc., higher prices often bring longer service life, especially in harsh environments. There is a certain gap in the working efficiency and reliability of equipment provided by high-quality excavator manufacturers.
We have clear requirements for manufacturers when choosing to buy new or second-hand excavators. Tiedou provides 16 different national brands of excavators, and models from 1 ton to 60 tons can be directly purchased. 60-100 tons models only need to be reserved, and you can also spend very little money to buy excellent performance equipment.
