The children's play equipment industry is an emerging industry. At present, the number of children's amusement parks invests more. However, for a set of children's play equipment, how long does it last, and what is the process of aging? I think this is a problem that many investors care about. Next, let Xiaobian of the company's health talk about the aging of children's amusement equipment.
For the operation of children's play equipment, we must pay attention to the safe operation of the equipment, and do daily maintenance work every day. For aging children's play equipment parts should be promptly replaced, record every day, let us introduce in detail the children's play equipment. Analysis of parts aging process.
(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, and the wear rate gradually decreases. When it reaches a certain degree, 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 stage.
During the running-in period, people consciously use the slight wear of this stage to create conditions for stable wear in normal operation. At this stage, for equipment that has not been run in, it should abide by regulations such as load reduction, deceleration, and reasonable operation, and increase viscosity. Low lubricating oil, as far as possible constant temperature and so on. In addition, in order to shorten the running-in period, appropriate advanced technology can be used to increase the utilization of the equipment. After running-in, the lubricating system is cleaned and the lubricant with quality requirements is used.
(2) Stable running-in phase. This stage is the normal working phase. After running-in, the friction surface is hardened. The micro geometry changes and the wear slowly and stably. In the later stage of this stage, due to the metal fatigue, the wear is relatively quick, but it can still be accelerated. Continue to work. When approaching the fatigue limit of 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 surface layer of the metal 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, and an increase in gaps, Lubrication conditions deteriorate, etc.), causing a sharp increase in the wear rate, a decrease in mechanical efficiency, loss of accuracy, abnormal noise and vibration, and a change in the mechanical properties of the material, which eventually leads to failure of the part and must be repaired.
