Shaft wear is a common equipment problem during shaft use. Shaft repair pointed out that there are many reasons for shaft wear, but the main reason is determined by the characteristics of the metal used to manufacture the shaft. Although the metal has high hardness, it has poor concession (the shaft cannot be restored after deformation) and has better impact resistance. Poor, poor fatigue resistance, so it is easy to cause adhesive wear, abrasive wear, fatigue wear, fretting wear, etc. Most of the shaft wear is not easy to detect, only when the machine is high temperature, large beating amplitude, abnormal noise, etc. Aroused people's awareness, but by the time they found out, most of the shafts had worn out, causing the machine to stop.
Comparison of solutions-Duomulai will tell you:
●New parts replacement
To replace the new shaft, the company considers replacing the problem shaft according to the downtime of the parts, the stock status and the value of the parts.
●Surfacing repair
It is not ideal to use welding rod surfacing technology to evaluate the actual effect. There are two main reasons: one is the difference in material; the other is the high temperature damage and thermal stress of repair welding. Developed countries in Europe and the United States have gradually phased out welding rod surfacing technology and dedicated polymer repair on-site technology.
●Brush plating spray
Brush plating and thermal spraying processes are usually limited by factors such as the degree of damage and the equipment itself, and the effect of use after repair is not ideal.
●Metal polymer technology
This kind of technology has been widely used in various medium and equipment. This type of material has high temperature resistance, high wear resistance, impact resistance, and good bonding strength and plasticity with metal. The repair effect meets the standard size, and the contact area can reach 100%. At the same time, this repair technology has no effect on the metal material, and can be repaired repeatedly to reduce scrap. Regardless of the repair effect or the economics, it has the superiority that the above three technologies can't compare.
