1. High‑Precision Flange Mating & Gasket Selection
- Rigorous machining – flange faces must be smooth and flat.
- Specialized gasket – oil‑resistant, aging‑resistant, with good resilience to fill microscopic gaps.
- Forms primary physical barrier for sealing integrity.
2. Explosion‑Proof Hinged Cover & Mechanical Clamping
- Explosion‑proof cover – prevents external sparks and withstands internal pressure.
- Mechanical clamping – after each gauging operation, firmly seat and lock the cover.
- Continuous downward pressure causes gasket to deform elastically, blocking oil vapor leakage.
3. Anti‑Corrosion Coating & Sealing Surface Protection
- Weather‑resistant coating – apply high‑quality paint to hatch exterior and non‑contact flange surfaces.
- Prevents rust and pitting on sealing contact surfaces.
- Avoid striking or scraping sealing surfaces to maintain smoothness and integrity.
4. Regular Inspections & Preventive Seal Replacement
- Include in regular inspection schedule – verify lid fastening and periodically open unit to check internal gasket condition.
- Inspect for cracking, deformation, or thinning.
- Immediately replace any damaged gasket to prevent leakage risks.
