Children's play equipment with a large degree of wear is very dangerous when used, because the wear level will cause many mechanical properties of children's play equipment to be unable to play, and it is very easy to lead to dangerous phenomena. Therefore, in order to make the children's play equipment run more smoothly, it is necessary to repair the more severely worn children's play equipment.

However, how should we determine the degree of wear and tear of children's play equipment and whether it needs to be repaired?

1. Ordinary friction. When the children's play equipment was just bought, all the parts were very smooth, and there was very little friction. At this time, we need to add lubricating oil to the places where friction is more likely to occur;

2. Stable running-in. At this time, hardening has occurred in the places where children's play equipment is easy to rub, and the microscopic geometry has changed. This is that we must continue to observe, and do a good job of lubrication and maintenance;

3. Severe wear and tear. When the children's play equipment is severely worn, the metal surface layer has basically reached the fatigue limit. At this time, it is very dangerous to use the children's play equipment and must be repaired. Generally, the wear of children's amusement equipment needs to go through the above three processes. In these three different processes, we have to take different treatment methods to deal with them.
