What are the four supporting packages of the excavator?
In the field of construction machinery, the "four packages" of an excavator is a key term, which refers to the combination of the four core components in the engine. This article will analyze in detail the composition, function and market status of the four supporting components of the excavator, and combine it with the hot topics on the Internet in the past 10 days to help readers fully understand this concept.
1. The composition of the four supporting components of the excavator
Excavator four packages usually include the following four core components:
| Part name | Function description |
|---|---|
| piston | Convert combustion pressure into mechanical kinetic energy |
| Piston rings | Sealing the combustion chamber and controlling oil consumption |
| cylinder liner | Orbits that provide piston motion |
| link | Connects the piston and crankshaft to transmit power |
2. The importance of supporting facilities
The four supporting components are the core component group of the engine, and their quality directly affects the excavator:
1. Power output efficiency
2. Fuel economy
3. Service life
4. Maintenance costs
According to industry data in the past 10 days, about 35% of excavator failures are related to the wear and tear of four supporting parts.
3. Current market hot topics
| hot topics | Attention | Related data |
|---|---|---|
| Implementation of National IV Emission Standards | high | 90% of new machines meet the standards |
| Four supporting localization rates | Middle to high | Reach 75% |
| Remanufacturing four packages | rise | Market share increased by 20% |
| New energy excavator | Hotspot | Sales volume increased by 150% in 2023 |
4. Things to note when purchasing four packages
1.Matching: Must exactly match the engine model
2.Material: High-quality alloy steel is more durable
3.brand: Choose products from regular manufacturers
4.Warranty: Provide at least 1 year warranty
According to the latest market research, the comparison of the service life of the four supporting packages of mainstream brands is as follows:
| Brand type | Average service life (hours) | Price range (yuan) |
|---|---|---|
| Original accessories | 8000-10000 | 15000-25000 |
| First-line subsidiary factory | 6000-8000 | 8000-15000 |
| Second-tier brands | 4000-6000 | 5000-8000 |
5. Maintenance suggestions
1. Change engine oil and filter regularly
2. Avoid working overloaded for a long time
3. Pay attention to the working status of the cooling system
4. Professional testing every 2000 hours
Recent industry reports show that standardized maintenance can extend the service life of four sets of equipment by more than 30%.
6. Future development trends
1. Material upgrade: application of nano coating technology
2. Intelligent monitoring: real-time wear warning system
3. Green manufacturing: improvement of environmentally friendly production processes
4. Modular design: quick replacement technology
With the development of the construction machinery industry, the four supporting technologies will continue to innovate to provide more efficient and durable power solutions for excavators.
