According to theoretical research on wear and combined with practical experience in production, there are many ways and means to prevent or reduce the wear of diesel generators. Therefore, in the daily use of diesel generators, it is necessary to reduce the wear of the unit as much as possible to prevent influence the service life of diesel generators.
Choosing suitable lubricants and lubrication methods, replacing dry friction with ideal fluid friction, is the most effective way to reduce friction and wear. For diesel generators, according to the specific requirements of different diesel generators, according to the different seasons and regions of use, the appropriate brand of lubricant should be selected.
2. Choose the right material
According to the form of basic wear, choose the material correctly: Material is one of the key factors to improve the wear resistance of mechanical spare parts. Materials with high fatigue strength, good corrosion resistance, wear resistance and high temperature resistance should be selected when designing and manufacturing. At the same time, attention should be paid to matching The solubleness of the material makes it have a suitable combination.
3. Perform surface treatment
Improve the surface by using various surface treatment methods, such as surface heat treatment (surface hardening of steel, etc.), surface chemical treatment (surface carburization and nitriding of steel, etc.), spraying, spray welding, plating, deposition, rolling, etc. The abrasion resistance. This is one of the most effective and economical methods.
4. Reasonable structure design
Correct and reasonable structural design is an effective way to reduce the wear of mechanical equipment parts and improve their wear resistance. The structure should be conducive to the formation and recovery of the surface protective film between the friction pairs, the uniform distribution of pressure, the dissipation of frictional heat, the discharge of wear debris, and the prevention of external abrasives and dust from entering. In structural design, you can apply the replacement principle, which allows one part in the system to wear out to protect another important part; you can also use the transfer principle, which allows another part in the friction pair to wear quickly and protect the valuable parts.
5. Improve working conditions
Try to avoid excessive load, excessive movement speed and working temperature, and create good environmental conditions.
6. Improve repair quality
Improving the quality of machining, repair, assembly, and installation are effective measures to prevent and reduce wear.
7. Correct use and maintenance
It is necessary to strengthen scientific management, conduct regular personnel training, and strictly implement operating procedures and other relevant rules and regulations. The equipment should be run-in correctly at the initial stage of use. In the course of use, it is necessary to do a good job in the maintenance of the oil supply system, air intake system and lubrication system to prevent the generation and intrusion of abrasives. Use advanced monitoring and testing techniques as much as possible.
