1. Optimizing the Sealing Structure Design is Essential
- The contact areas between the cover and the tank must be precisely dimensioned to ensure a tight fit and minimize gaps.
- Annular grooves can be provided on the contact surfaces to allow the seal to fully engage and fill the gap, forming an effective sealing barrier.
- The cover edges must be smooth and flat to avoid deformation or burrs that could cause a poor seal.
2. Selecting Appropriate Sealing Components is Critical
- Oil-resistant and age-resistant sealing materials, such as nitrile rubber or fluororubber, should be selected based on the characteristics of diesel fuel.
- These materials offer long-term resistance to diesel corrosion and maintain elasticity.
- The cross-sectional shape of the seal must match the sealing structure to ensure uniform force distribution when the cover is closed.
3. Standardizing the Cover Installation Method Can Enhance Sealing Performance
- The cover and tank connection must utilize a reliable locking mechanism, such as snaps or bolts.
- During installation, check that the cover is level to avoid uneven force on the seals due to tilt.
- Ensure uniform pressure during closing to fully compress the seal.
4. Enhanced Routine Maintenance Can Extend the Life of the Seal
- Regularly clean the contact surface between the cover and the housing to prevent foreign matter from affecting the seal.
- Inspect the seals for signs of hardening, cracking, or deformation.
- Replace any problems promptly to prevent leaks caused by seal aging.
5. Take Protective Measures for Special Environments
- In high-temperature environments, keep the cover out of direct sunlight for extended periods.
- In low-temperature environments, protect the cover and seals from freezing to prevent hardening.
- In dusty or humid environments, install a protective cover to reduce contaminants from corroding the seals.
