What kind of oil should be added to Komatsu excavator? Comprehensive analysis of fuel, hydraulic oil and lubricating oil selection guide
In the field of construction machinery, Komatsu excavators are highly favored for their excellent performance and reliability. However, correct oil selection is critical to the longevity and efficiency of your equipment. This article will combine recent hot topics in the construction machinery industry to provide you with detailed answers to the selection criteria for various oil products for Komatsu excavators, and attach structured data for easy reference.
1. Review of recent hot topics in the construction machinery industry (last 10 days)
| hot topics | Main content | relevance |
|---|---|---|
| Implementation of National IV Emission Standards | Many places strengthen emission inspections of non-road machinery | Affects diesel selection |
| Lubricating oil prices rise | Many brands announced price increases of 5%-8% in May. | Oil cost increases |
| AI intelligent maintenance system | New technology predicts oil change intervals | Optimize maintenance plan |
2. A complete guide to selecting Komatsu excavator oils
1. Diesel selection criteria
| Model series | Recommended label | Sulfur content requirements | Things to note |
|---|---|---|---|
| PC200-8 | 0#/-10# | ≤50ppm | Anti-condensation is required in winter |
| PC360-11 | National VI standards | ≤10ppm | Must add original fuel treasure |
2. Technical requirements for hydraulic oil
| Oil type | Certification standards | Replacement cycle | Applicable temperature |
|---|---|---|---|
| HM46 anti-wear hydraulic oil | ISO VG46 | 2000 hours | -15℃~50℃ |
| HV68 low temperature hydraulic oil | DIN51524 | 3000 hours | -30℃~40℃ |
3. Specifications for oil used in lubrication systems
| Lubrication parts | Oil grade | Replacement cycle | special request |
|---|---|---|---|
| engine oil | CI-4 15W-40 | 500 hours | ACEA E7 certification required |
| Rotary gearbox | GL-5 85W-90 | 1000 hours | Contains extreme pressure additives |
3. Usage suggestions and common misunderstandings
1. Hazards of mixing oil products
Recent industry reports indicate that approximately 35% of hydraulic system failures are caused by oil mixing. Even for hydraulic oils of the same brand and different models, their additive formulas may conflict, resulting in:
- Accelerated sludge generation
- Expansion and deformation of seals
- The filter element is clogged in advance
2. Dynamic adjustment of oil change intervals
According to recent data collected by the intelligent monitoring system, the oil change cycle needs to be shortened by 30% under the following working conditions:
- Long-term operation in dusty environment
- Daily cold start frequency > 5 times
- Sustained high temperature (oil temperature >90℃) working conditions
4. The impact of industry development trends on oil product selection
Based on industry trends in the past 10 days, the following trends are worthy of attention:
1. The rise of bio-based hydraulic oils
Many manufacturers have launched degradable hydraulic oil products, whose performance parameters are close to traditional oil products. It is expected that the market share will increase by 150% in the next three years.
2. Blockchain traceability of oil products
The newly released oil product verification system can query full-link data such as production batches, transportation and storage through QR codes, effectively preventing counterfeit products.
Conclusion:
Correct selection of oil is the basis for ensuring efficient operation of Komatsu excavators. Users are advised to:
1. Strictly follow the oil specifications in the operating manual
2. Purchase oil products through formal channels
3. Establish a complete oil usage file
4. Pay attention to the development of new technologies in the industry
