What butter is used for the loader? Comprehensive analysis of grease selection and maintenance guide
In the field of engineering machinery, the maintenance of loaders is crucial, and the choice of grease (commonly known as "butter") directly affects the life and performance of equipment. This article will combine popular topics across the network for the past 10 days to structure the key points of loader butter selection and provide practical data comparison.
1. Recent review of hot spots in the construction machinery industry
According to big data monitoring, popular topics in the field of engineering machinery in the past 10 days include: popularization of new energy equipment, upgrading of lubricating material technology, optimization of equipment maintenance costs, etc. Among them, the issue of loader grease selection increased by 35% in multiple technical forums, becoming the focus of operators.
| Hot keywords | Discussion Hot Index | Associated device type |
|---|---|---|
| Lithium-based grease | 8.7/10 | Loader/excavator |
| Complex calcium sulfonate | 7.2/10 | Heavy duty construction machinery |
| Biodegradable oils and fats | 6.5/10 | Environmentally friendly equipment |
2. Core indicators for loader butter selection
According to ISO standards and mainstream manufacturers' suggestions, loader grease must meet the following technical requirements:
| Performance parameters | Standard value | Test Method |
|---|---|---|
| Drop point temperature | ≥180℃ | ASTM D2265 |
| Base oil viscosity | 220-460cSt | 40℃ detection |
| Extreme pressure performance | ≥588N | Four-ball test |
3. Comparative analysis of mainstream butter types
Currently, the mainstream loader grease in the market can be divided into three categories, and its performance comparison is as follows:
| type | advantage | shortcoming | Applicable working conditions |
|---|---|---|---|
| Lithium-based grease | High cost performance and versatility | Normal high temperature stability | 0-120℃ regular operation |
| Complex calcium-based lipid | Excellent water resistance | Poor low-temperature pumping | Humid/dusty environment |
| Polyurea-based grease | Extra-long service life | Higher cost | High temperature heavy duty conditions |
4. Practical application suggestions
1.Daily maintenance: It is recommended to use NLGI grade 2 lithium-based grease, and replenish lubrication every 200 hours or weekly
2.Extreme working conditions: Extreme pressure grease containing molybdenum disulfide should be used in mining operations
3.Winter maintenance
5. Latest views of industry experts
A recent seminar of the China Engineering Machinery Industry Association pointed out:
• Loader grease consumption is expected to reach 42,000 tons in 2023
• Synthetic grease market share increased by 12% year-on-year
• The repair cost caused by wrong fat selection accounts for 17%
Conclusion:The correct choice of loader butter requires comprehensive consideration of the equipment model, operating environment and maintenance cycle. It is recommended to check the grease status regularly and replace it immediately when there is obvious hardening, discoloration or impurities. Through scientific use of fat, the equipment life can be extended by more than 30%, significantly reducing operating costs.
