Fault analysis and preventive measures of shaft forgings are the key work to ensure the normal operation and prolong the service life of shaft forgings. The following is the analysis of the common faults of shaft forgings and the corresponding preventive measures:
1. Rupture failure:
Failure cause: Fracture is usually due to material overload, fatigue, corrosion and other factors.
Preventive measures: enhance the strength and toughness of the material, avoid overload and fatigue loading, and regularly perform surface anti-corrosion treatment.
2. Wear failure:
Cause of failure: shaft forgings in operation due to the impact of load and friction and other factors, there will be wear phenomenon.
Preventive measures: Use high-strength wear-resistant materials, improve lubrication conditions, strengthen equipment maintenance, and regularly replace worn parts.
3. Corrosion failure:
Failure cause: shaft forgings exposed to damp, corrosive media, prone to corrosion.
Preventive measures: Choose materials with good corrosion resistance, strengthen anti-corrosion treatment of the surface, check regularly and carry out maintenance.
4. Fatigue failure:
Failure cause: shaft forgings subjected to reciprocating load for a long time, easy to appear fatigue fracture.
Preventive measures: Optimize design, improve material properties, avoid overload use, and adjust working conditions reasonably.
5. Bending failure:
Failure cause: shaft forgings may bend and deform during use due to external force or unreasonable design.
Preventive measures: reasonable design of the structure, select high-strength materials, control external force, avoid overload.
The above is the analysis of common failures of shaft forgings and the study of preventive measures, through scientific preventive measures can effectively extend the service life of shaft forgings, improve the reliability and safety of equipment.
