What is an excavator booster?
In the field of construction machinery, the excavator supercharger is a key component, especially playing an important role in improving engine performance and fuel efficiency. This article will introduce in detail the definition, working principle, common types and maintenance points of excavator boosters, and attach structured data for reference.
1. Definition of excavator booster
The excavator supercharger, also known as a turbocharger, is a device that increases the air intake of the engine by compressing air. It uses exhaust gases from the engine to drive a turbine, thereby increasing the engine's power and torque while reducing fuel consumption and emissions.
2. Working principle
The working principle of the excavator booster can be divided into the following steps:
1. Exhaust gas drives the turbine: The high-temperature and high-pressure exhaust gas discharged from the engine drives the turbine to rotate at high speed.
2. Compressed air: The turbine drives the coaxial compressor impeller to compress the fresh air and send it into the engine cylinder.
3. Improve combustion efficiency: The density of compressed air is higher, allowing fuel to be burned more fully, thereby increasing power output.
3. Common types and comparisons
| type | Features | Applicable scenarios |
|---|---|---|
| supercharger | Directly driven by the engine, fast response but low efficiency | Small excavator or low speed working conditions |
| turbocharging | Using exhaust gas to drive, high efficiency but turbo lag | Large and medium-sized excavators or high-load operations |
| Electronically controlled boost | Combined with electronic control technology, balance power and fuel consumption | New energy-saving excavator |
4. Maintenance points
In order to ensure the long-term stable operation of the excavator booster, the following maintenance matters need to be paid attention to:
1.Check oil lines regularly: The supercharger relies on engine oil for lubrication, so the oil must be kept clean and replaced in time.
2.Avoid cold start and high load: After starting, it should run at idle speed for 1-2 minutes and wait until the oil is fully lubricated before working.
3.Clean air filter: Prevent impurities from entering the supercharger and causing impeller wear.
5. Recent industry hot spots (last 10 days)
