The sealing performance of a fuel cube tank directly affects the risk of fuel leakage. Maintenance should focus on key components such as seals and interfaces, combining daily inspections with regular maintenance to build a comprehensive protection system.
1. Daily Inspection & Troubleshooting
- Regularly inspect key sealing components such as tank interfaces, valves, and pipeline connections.
- Carefully observe for any signs of fuel leaks, moisture accumulation, or staining around connections.
- Examine seal appearance for signs of aging, cracking, deformation, or deterioration.
- Monitor tank pressure changes regularly; abnormal pressure drops may indicate seal failure.
- Investigate and address potential seal issues early to prevent leakage incidents.
Inspection Frequency
Perform visual inspections daily, detailed inspections weekly, and comprehensive pressure tests monthly for optimal leak detection.
2. Seal Maintenance & Replacement
- Select oil-resistant and corrosion-resistant seals specifically designed for fuel tank applications.
- Regularly apply special lubricating grease to seals to enhance performance and extend wear resistance.
- If seals show signs of aging, cracking, or damage, replace them entirely rather than attempting partial repairs.
- Avoid using locally damaged seals, as they can lead to complete sealing failure and fuel leakage.
- After replacement, conduct a comprehensive sealing test to ensure proper fit and absence of leaks.
Replacement Protocol
Always replace seals according to manufacturer specifications. Never reuse old seals or mix seal types within the same system.
3. Interface Strengthening
- Regularly check the tightness of all pipe connections and valve installation interfaces.
- Prevent connection loosening caused by vibration, pressure changes, or thermal expansion/contraction.
- Use appropriate sealing tape or sealant to enhance connection integrity and ensure seamless joints.
- Avoid physical impacts to interfaces that could damage the sealing structure or compromise connections.
- Establish a torque specification for all critical connections and verify during maintenance.
Tightening Schedule
Check and retighten all critical connections quarterly, or after any significant pressure or temperature fluctuations.
4. Environmental Adaptability Protection
- Avoid prolonged exposure of tanks to high temperatures, high humidity, and corrosive environments.
- High temperatures accelerate seal aging and degradation, reducing service life.
- Humidity and corrosive agents damage sealing structures and promote material breakdown.
- Outdoor tanks should be equipped with sunshades and rain protection to minimize environmental exposure.
- Regularly clean surrounding corrosive debris and contaminants from tank surfaces.
- Perform anti-corrosion treatments on tanks to indirectly ensure sealing system stability.
Temperature Consideration
Seal materials have specific temperature ranges. Ensure selected seals are appropriate for your climate conditions and potential temperature extremes.
