In the construction of excavators, safety is always at the forefront. What
are the safety requirements and precautions for driving an excavator? How to
safely drive a small excavator in different terrain? As a Bucket Teeth Wholesale, share with you.
Because the main customer base of excavators is distributed in rural and urban areas across the country, the excavator has high efficiency and strong mobility. Most of them have their own trailers, which are located between the mountains and the jungle.

First, the trailer cannot be too high, nor can it be easily wiped.
Second, the brakes must be air brakes, water jet brakes, long-term downhill brakes, the brakes are easy to soften, and even the accidents of cars hitting cliffs are mostly caused by oil brakes.
Third, it is recommended to stop the air brake when parking. If there is no air brake, the wheel must be placed on the stone when the excavator moves up and down. It is not enough to step on the brake. The experience of the excavator sliding with the trailer is poor.
In addition to engine carbon deposition, the excavator teaches you three construction tools, such as the harsh environment of excavators and forklifts. The machine is often overloaded for a long time. In addition, poor quality diesel is often used in construction sites, so the vehicle's engine may have carbon deposition.
Carbon deposition is a dense carbon oil compound. Because diesel and engine oil are not completely burned into the cylinder, the oil accumulates on the surface area of the engine cylinder head, cylinder liner, piston, valve, combustion chamber, fuel injector, etc. The thermal conductivity is poor. Long-term accumulation will cause local overheating of the components. Serious nozzle, valve ablation, piston ring blockage and cylinder pulling will cause serious failures. In addition, if carbon deposits accumulate on the surface of the combustion chamber, it will also cause The increase in compression ratio, pre-combustion, knocking, etc., seriously affects the power and fuel consumption of the engine. Therefore, the excavator must regularly check the carbon deposit and remove the carbon deposit for maintenance.
Method 1: Mechanical grinding and depositing carbon is a simple and straightforward method of mechanical polishing with tools. You can use a wire brush, scraper, bamboo or emery cloth to wipe the carbon deposit. Special tools can be used for parts with special shapes. Carbon deposition For example, a thin steel wire brush can be used to clean the carbon deposits around the nozzle, the pressure chamber is made of a special needle. Valve rail and valve seat carbon can be removed with a cylindrical steel wire brush.
Method 2: The principle of sand blasting is similar to sand blasting, but the sand blasting particles are not sand. When the core is blasted, high-speed airflow is used to spray walnut sand onto the surface of the part to remove carbon deposits and oil stains. This method requires special equipment and is difficult to be widely used. Our company also has Hitachi Bucket Teeth for sale, please contact us.
