The cooling system is very important for the construction vehicle engine. After a certain period of use, various precipitations will occur inside. The type of sedimentation varies due to different vehicle maintenance conditions. For most engineering vehicles, water is used normally, and antifreeze is used in winter. In this case, the precipitate produced is mainly scale; some owners use antifreeze for a long time, and the precipitation that appears is scale and gel. The Lord's dirt.
The main reasons for the failure of the cooling system are: high engine water temperature in summer, low engine water temperature in winter, and leakage of cooling system.
There are many reasons for engine overheating. The most common cause is the result of the cooling system's cooling effect due to the internal fouling and sedimentation of the cooling system blocking the channel. A common practice to rule out such failures is to disassemble the tank for a full replacement, but it turns out that many cars have not improved as a result. Leakage of the engine cooling system mainly takes the form of leaking water tanks, water leakage from the upper and lower water pipes, and water leakage from the cylinder mats.
To deal with the engine temperature is too high, especially due to the problems caused by excessive dirt and sedimentation, we can use high-end cleaning agent with the manufacturer's special equipment for processing. When choosing a cleaning agent, we have 3 recommendations: For a significant portion of the precipitated material, cleaning with an acidic cleaner will have a good effect. If the gel is not hard, it can be cleaned with alkaline or non-corrosive cleaners. For oily substances that appear in the cooling system, use acidic cleaners for cleaning.
Considering all the three conditions mentioned above, and the precipitation in the engine cooling system that I have passed is mainly oily substances and rust. The cleaner used must be acidic to be suitable for the domestic automotive market. At present, the alkaline cleaners that I've been on the market are mainly based on the fact that it can only adapt to the needs of a small number of cars.
The above is a brief introduction of Xiao Bian’s maintenance of the engine of the engineering vehicle. If there are still problems, we can contact our staff. (Wen/Jun Xun)
301 Stainless Steel Cut Wire Shot
Longlived 301 Stainless Steel Shot is made from high quality 301 stainless steel wire by drawing, cutting and round. It has been widely used on surface treatment of springs, gears, screws, chains and many other dis casting parts for surface treatment of deburring, anti-corrosion, anti-fatigue and so on.
Its advantage is as below:
1. It is obtained by cutting the wire so that there is no hallowness one in bulk. It has a great durability and long service life. It's
2. The cutting process is fully completed by automatic machine so its particle fineness is extremely uniform.
3. Grinding process changes the surface of Stainless Steel Shot to make parts have a fine and smooth surface.
4. It has a great characteristics of moderate hardness, high strength and good toughness. When used in shot blasting machine, it will not be broken easily and could save much time and cost.
5. It will not rust even in a wet environment for a long time due to its material of stainless steel.
Using Longlioved 301 Stainless Steel Shot could make shot blasting faster, safer and cleaner. Welcome all of clients to connect with us to learn more.
