1. During the use, transportation and replacement of excavator parts, bumps, paint peeling, rust, etc. often occur, especially heavy iron parts, as long as the parts themselves are normal and do not delay use, most car owners will think it is normal .
In fact, after these parts are peeled off and rusted, it is best to stick a paint film once. Surface painting is a convenient, quick and inexpensive method of protection. If the metal parts have been damaged, the damaged parts must be removed first, and then a rust-proof coating should be applied. This is much less likely to rust even if the part is used a lot.
2. The choice of anti-rust layer and lubricant is also a knowledge. For example, old drivers will directly buy calcium-based grease and lithium-based grease, because long-term accumulated experience tells us that these greases can achieve twice the result with half the effort. The first point goes without saying that they can bring the part to the intended use and condition. In addition, if the car owner wants to replace the new grease, the original grease can be quickly replaced, which is easy to clean.
3. For the anti-rust treatment under special circumstances, such as in summer, with a lot of rain and high temperature, many car owners will choose to stop work for a period of time, because the huge body of the excavator cannot be stored in a closed environment such as a garage like a car, so the anti-corrosion Special attention should be paid to rust work.
For example, before the excavator needs to be parked for a long time, the engine antifreeze must be updated and refilled, and the antifreeze of the same brand must be replaced, which is to prevent the engine waterway from rusting after long-term parking.
For example, before shutdown, the fuel tank should be filled with oil to prevent the fuel tank from rusting due to long-term storage, air, rain and other corrosion.
4. During the construction process of the excavator, it is easy to scratch the left and right buttocks. When the paint surface is scratched and peeled off, the old driver will repair the paint surface and spray paint before leaving get off work to prevent the scratched parts from rusting and other problems.
