Long-term solution of anti-corrosion performance of connecting rod lock
I. Introduction
As an important part of mechanical system, connecting rod lock is widely used in various equipment. However, in the harsh working environment, the connecting rod lock is easily corroded, which leads to its functional failure or shortened life. Therefore, it is of great significance to study and put forward effective anti-corrosion measures for improving the service life of connecting rod locks.
Second, the corrosion mechanism analysis of connecting rod lock
The corrosion of connecting rod lock is mainly divided into chemical corrosion and electrochemical corrosion. Among them, chemical corrosion refers to the oxide produced by the direct chemical reaction between the metal surface and the surrounding medium; Electrochemical corrosion refers to the corrosion phenomenon caused by the electrode reaction of metals in electrolyte solution. In addition, environmental factors such as humidity and temperature will also affect the corrosion speed of connecting rod lock.
Third, the anti-corrosion measures of connecting rod lock
1. Selection of corrosion-resistant materials: Choosing suitable materials is the first step to prevent the connecting rod lock from rusting. Usually, alloy steel with good corrosion resistance such as stainless steel can significantly reduce the corrosion degree of connecting rod lock.
2. Application of surface treatment technology: Proper surface treatment (such as coating and spraying preservative) for connecting rod lock can prevent the influence of external media on its body to a certain extent and achieve the purpose of preventing corrosion.
3. Strengthen the seal design: through improving the structural design, improve the tightness between the parts of the connecting rod lock, reduce the possibility of moisture entering, and then inhibit the occurrence of corrosion;
4. Regular maintenance: regularly check and clean up the dirt and pollutants on the connecting rod lock, and apply proper amount of grease to keep it in good working condition.
IV. Case Analysis —— Practice of Long-term Anticorrosion Scheme for Connecting Rod Lock of a Company
In order to solve the problem of frequent damage of connecting rod locks in the production line, a company took the following measures in the production process:
(1) replacing the original ordinary carbon structural steel with CrMoV alloy steel;
(2) forming a protective film on key parts by adopting a nickel-based alloy thermal spraying process;
(3) A waterproof rubber ring is arranged at the joint;
After a period of operation, it is found that these measures effectively control the corrosion of connecting rod lock and greatly extend its service life.
V. Conclusion
To sum up, in view of the corrosion problem faced by connecting rod locks, we can achieve effective prevention and control through reasonable material selection, scientific use of surface protection technology and strengthening structural design. Of course, it is impossible to completely avoid corrosion by any means, and the best effect can be achieved only by organically combining various means. I hope this article can provide some useful reference suggestions for enterprises to help them better solve the problems encountered in practical work.
