Girls wear new shoes, and they always wear feet, bleeding, and blisters a few days ago. These are the things that must be experienced because this is the running-in period. After the running-in period, the shoes will be comfortable to wear. It's not just about shoes, the rest is the same. Children's play equipment is sought after by the public, but it also has a run-in period. Today, Xiao Bian wants to tell you what problems children's play equipment should pay attention to during the run-in period.
1. Run-in phase
The surface of the new friction pair has a certain degree of roughness, and the actual contact area is very small. Therefore, when the wear-in begins, the wear is very rapid. As the running-in proceeds, the rough surfaces are gradually flattened and the actual contact area gradually increases. The surface becomes smoother and smoother, the wear rate gradually decreases, and when it reaches a certain level, it tends to be stable, which is the end of the running-in period. The amount of wear during this period is called the initial wear.
The running-in phase is the conscious use of the slight wear of this stage to create conditions for stable wear during normal operation. In this stage, for children's playground equipment that has not been worn out, provisions such as load reduction, deceleration, and reasonable operation should be followed, lubricants with low viscosity should be added, and constant temperature should be kept as far as possible. In addition, suitable wearables can be used to shorten the running-in period. Advanced technology, etc., to improve the utilization of equipment, after the completion of the run-in, clean the lubrication system, use lubricants that meet the quality requirements.
2. Stable running-in phase
This phase is the normal working phase. After running-in, the friction surface is hardened, the micro geometry changes, and wear slowly and stably. In the later stage of this stage, due to metal fatigue, wear is relatively accelerated, but it can continue to work. When approaching the fatigue limit of the metal, the machine must be regularly overhauled to prevent the machine from causing serious mechanical accidents due to excessive wear.
3. Severe wear stage
At this stage, due to the fact that the metal surface layer basically reaches the fatigue limit, the friction conditions undergo major changes (such as a sharp increase in temperature, a significant change in the surface metal structure, a change in the micro geometry, an increase in the gap, deterioration of the lubrication conditions, etc.), The rapid increase in wear rate, mechanical efficiency, loss of precision, resulting in abnormal noise and vibration, coupled with changes in the mechanical properties of materials, eventually leading to parts failure, must be maintained.
