Rubber seal ring is the key sealing material in underground engineering, its pollution resistance is directly related to the long-term stable operation of the project and environmental protection. This paper will deeply discuss the performance of rubber seals in underground engineering, as well as long-term use considerations.
Analysis of pollution resistance
Material selection key: Rubber sealing ring is usually made of nitrile butadiene rubber (NBR), fluorine rubber (FKM) and other oil-resistant, corrosion-resistant materials, can effectively resist the erosion of groundwater, sewage and other chemicals, keep the sealing effect stable.
Chemical resistance: the sealing ring needs to have good acid and alkaline resistance, which can resist the erosion caused by chemicals in groundwater and prevent the sealing performance from being reduced due to chemical media.
Prevention of pollution: In underground engineering, the sealing ring not only needs to prevent external pollutants from entering the engineering facility, but also needs to avoid the leakage of liquid media in the engineering facility to protect the safety of groundwater resources and the surrounding environment.
Long-term usage considerations
Durability analysis: Considering the complexity of the underground engineering environment, the sealing ring needs to have good wear resistance and anti-aging ability, and can withstand the impact of groundwater pressure and soil movement on it for a long time to ensure the long-term sealing effect.
Regular inspection and maintenance: It is recommended to check the service status of the seal regularly, monitor its wear and aging, and replace and maintain it in time to extend the service life of the seal and reduce unnecessary maintenance costs caused by failure.
Environmental adaptability: the sealing ring needs to adapt to temperature changes and humidity changes in the underground environment, maintain its material elasticity and sealing performance, and is not affected by the negative effect of the external environment.
Practical application case
Subway tunnel construction: In the pipeline connection of the subway tunnel and the sealing of the waterproof wall, the rubber sealing ring effectively prevents the penetration of underground water, and maintains the stability of the tunnel structure and the operation safety.
Underground pipeline engineering: In the joint and valve sealing of municipal pipelines, rubber seals are widely used to ensure the stable operation of underground pipeline systems and prevent leaks and pollution.
conclusion
The rubber sealing ring shows excellent pollution resistance and long-term stable use effect in underground engineering, which is an important safeguard measure to ensure the safe operation of engineering facilities and environmental protection. Through scientific selection of materials, reasonable design and effective maintenance, the function of the sealing ring can be maximized to ensure the continuous safe and reliable operation of underground engineering.
