Daily maintenance of small excavators

1. The impact of diesel quality on excavator engines

The quality of diesel directly affects the normal operation, operating efficiency and service life of excavator engines. If inferior diesel is used, the following problems may occur:

Incomplete combustion: Impurities in inferior diesel will cause incomplete combustion and increase carbon deposits. These carbon deposits will accumulate in the cylinder, affecting the efficiency and performance of the engine.

Excessive wear: Excessive carbon deposits in the cylinder will accelerate the wear of the cylinder liner and piston ring, shortening the service life of the engine.

Decrease in economic benefits: Inferior diesel not only increases the cost of maintenance and replacement of parts, but also reduces the operating efficiency of the excavator, affecting the progress of the project and economic benefits.

Safety hazards: Inferior diesel may cause engine failure and increase the risk of safe production.

2. The impact of hydraulic oil quality on the hydraulic system of the excavator

Hydraulic oil plays an important role in energy transmission, lubrication, corrosion prevention, rust prevention and cooling in the hydraulic system. The impact of the quality of hydraulic oil on the hydraulic system includes:

High failure rate: Statistics show that 60% to 70% of hydraulic system failures are caused by hydraulic oil quality problems. Inferior hydraulic oil can cause wear and damage to components such as hydraulic pumps, valves and actuators.

System performance declines: Impurities in hydraulic oil will clog the oil circuit, affecting the efficiency and stability of the system.

Shortened component life: Poor quality hydraulic oil cannot effectively lubricate and prevent rust, resulting in increased corrosion and wear of components, shortening their service life.

3. The impact of lubricant quality on excavators

The role of lubricants in mechanical equipment is to reduce friction, reduce wear, and extend the service life of equipment. The impact of poor quality lubricants on excavators includes:

Increased wear: Poor quality lubricants cannot form an effective lubricating film, resulting in increased wear of engine rotating parts (such as crankshafts, connecting rods, etc.).

Component damage: Poor quality lubricants can damage key engine components. Once these components have problems, the service life of the engine will be greatly shortened.

Performance decline: Poor lubrication can cause unstable engine operation, reduced efficiency, and increased maintenance costs.

Summary

Whether it is diesel, hydraulic oil or lubricating oil, the quality of oil plays a vital role in the maintenance and performance of excavators. Choosing high-quality oils can effectively reduce equipment failures, extend equipment life, and improve operating efficiency. Especially for novice operators, they must learn to distinguish between good and bad oils and avoid using inferior oils to ensure the normal use and safe production of the excavator.
