Wear resistance of rubber seal ring in rail transit equipment and maintenance management suggestions

As the key seal of rail transit equipment, the wear resistance of rubber sealing ring is directly related to the reliability and operating life of the equipment. This paper will deeply discuss the wear resistance characteristics of rubber seals in rail transit equipment, and provide suggestions for maintenance management.

The wear resistance characteristics of rubber sealing ring

Material selection key: In rail transit equipment, rubber seals often use wear-resistant rubber materials, such as nitrile butadiene rubber (NBR), fluorine rubber (FKM) and so on. These materials can maintain good wear resistance in long-term use, resistance to friction and wear.

Surface lubrication and treatment: In order to reduce friction loss, the sealing ring can be properly lubricated or coated during installation to enhance the friction effect between the sealing ring and the fitting and extend the service life.

Anti-aging ability: high-quality rubber seals have excellent anti-aging ability, which can maintain elasticity and sealing effect in harsh environmental conditions for a long time, such as anti-UV, anti-oxidation and other characteristics.

Maintenance management suggestions

In order to ensure the long-term reliable operation of rubber seals in rail transit equipment, the following are suggestions for maintenance management:

Regular inspection and replacement: Check the wear of the seal ring regularly, and replace the badly aged or damaged seal ring in time to avoid equipment failure due to seal failure.

Keep clean and lubricated: clean the surface of the sealing ring regularly to avoid dust and impurities entering the sealing gap and affecting the sealing effect. Lubricate properly when needed to reduce friction losses.

Pay attention to the working environment: Avoid rail transit equipment in high temperature, high pressure or harsh working environment for a long time, these conditions are easy to accelerate the aging and wear of the seal ring.

Reasonable storage and installation: When storing and installing the seal ring, avoid moisture, high temperature and direct sunlight to maintain the original performance and life of the seal ring.

Practical application case

Rubber seals are widely used in rail transit equipment, such as the door seal of subway trains, the pipeline seal of air conditioning systems, etc., which are an important part of ensuring the safe operation of equipment and passenger comfort.

Conclusion

By selecting suitable materials and taking effective maintenance management measures, the wear resistance and service life of rubber seals in rail transit equipment can be maximized.
