Maintenance and Fault Diagnosis
Daily Maintenance:
Clean the exterior dust of the casing weekly to prevent the ventilation holes from getting blocked.
Check the aging condition of the sealing ring monthly (if cracks or hardening occur, replace immediately).
Tighten the bolts quarterly (torque according to the manufacturer's specifications, such as M8 bolts at 20-25 N·m).
Common Faults and Solutions:
Casing cracking:
Reasons: material fatigue, impact load, drastic temperature changes.
Solution: Replace the casing, add reinforcing ribs or switch to a higher-strength material.
Sealing failure:
Reasons: improper installation of the sealing ring, aging, insufficient compression.
Solution: Reinstall the sealing ring, check if the sealing groove is damaged, and replace the material if necessary (such as upgrading to fluororubber).
Poor drainage:
Reasons: clogged drainage outlet, faulty drainage valve.
Solution: Use compressed air to blow the drainage outlet, replace the drainage valve (recommend using an electronic sensor type, increasing reliability by 50%).
Latest Technology Trends
Integrated Design: Integrate the filter element, sensor, and drainage valve into the casing to reduce assembly processes (for example, a certain brand's air compressor casing integrates a differential pressure sensor to monitor the filter element status in real time).
Smart Materials:
Self-healing plastic: The surface of the casing can automatically heal when scratched at 70°C (such as epoxy resin containing DCPD microcapsules).
Antibacterial materials: Add silver ion antibacterial agents to inhibit bacterial growth (suitable for medical equipment).
3D Printing Manufacturing:
Quick prototype verification: Shorten the R&D cycle (from traditional 4 weeks to 3 days).
Customized production: Mass production of small-batch, multi-variety casings (costs reduced by 30% compared to traditional processes).
