What are the oil change methods for the new mini excavator? Let's take a look together
Never use kerosene or diesel as a cleaning fluid. When the excavator is repaired and cleaned, the flow should be as large as possible to make the flow in the pipeline turbulent and complete the action of each actuator to flush the pump components, noise and pollutants in the hydraulic cylinder. After the cleaning is completed, the cleaning fluid is discharged in a hot state, and new working oil is added according to the method of replacing the oil. According to the test, the temperature of the hydraulic system is generally most suitable in the range of 35℃ to 60℃, and should not exceed 80℃. At normal oil temperature, the hydraulic oil performs well.
How to deal with the carbon deposit of the excavator engine better
First of all, what is a carbon deposit? Carbon deposit is actually a product that is not completely burned. When the engine is working, the unsaturated olefins and colloids in the oil and fuel will not be completely burned at high temperatures, and the excavation will correct the black coke-like substance, which is generally called carbon deposits. It can be divided into valve, combustion chamber carbon and intake manifold carbon.
Why does the excavator engine carbon accumulate? The excavator engine may encounter various faults during use. Repairing excavator carbon deposits is a common type. If not, let's talk about the three reasons for excavator engine carbon accumulation. 1. There are too many impurities in the fuel during daily use of the excavator. In real life, the fuel cannot be completely pure. The filter also has filtering restrictions, and some small impurities in the fuel are burned and carbonized in the cylinder to produce carbon deposits.

2. The moving parts in the engine are worn. When the engine is working at high speed, the brand new mini excavator manufacturer in the cylinder, cylinder liner, valve, piston, piston ring, etc. will produce debris due to wear, the debris will accumulate in the cylinder, and the valve will be carbonized.
3. The air intake is not clean. The filter cannot completely filter out the impurities entering the air. Some impurities in the excavator will enter the combustion chamber, and the carbon will appear carbonized after combustion. What are the effects of engine carbon accumulation? 1. Carbon accumulation reduces the power of the engine, resulting in uneven engine power output; it also increases fuel consumption. 2. The more carbon deposits there are in the piston groove, the more it will stick to the piston ring, causing the piston ring to deform, scrape the cylinder liner, and pull the cylinder. 3. A lot of carbon deposits sometimes block the fuel injection port and require the replacement of the injector. 4. When there is too much carbon deposit on the valve, the valve pressure is uneven and the valve stem breaks.
The new mini excavator oil change method and carbon deposit treatment are here, I hope it will be helpful to you.
