Automated production lines and robotic equipment rely heavily on pneumatic systems. Tiny air leakage and pressure relief are difficult to detect visually, but continuously cause energy waste, jitter, precision deviation and increased defective rate. Most factories only repair after obvious failures without periodic replacement standards, leading to long-term sub-health operation of pneumatic systems.
| Failure Phenomenon | Main Cause | Quick Solution |
| Micro leakage at joint | Aging O-ring, inclined assembly, impurity jamming | Replace seal, clean interface and re-lock vertically |
| Pipe cracking & bulging | Long-term bending fatigue, high-temperature softening, friction wear | Cut damaged section and reconnect; adopt anti-bending PU pipe for frequent bending areas |
| Ferrule joint pressure relief | Vibration-induced thread loosening & failed clamping | Re-tighten ferrule nut and apply thread locker for vibrating equipment |
| Internal valve air channeling | Worn valve core seal, oil dirt jamming, incomplete closing | Disassemble & clean valve, replace seal kit or entire valve |
1. Low-pressure assembly lines: Standard PU pipes and plastic quick fittings for cost-effective daily operation; 2. High-pressure stamping equipment: Metal copper joints and high-pressure crack-resistant pipes to avoid burst and leakage; 3. High-frequency robotic equipment: Fatigue-resistant seals and anti-bending pipes to slow aging; 4. Dust & oil pollution workshops: Dustproof sealed joints and oil-resistant rubber seals to prevent impurity invasion.
1. Seals, O-rings and gaskets: Batch replacement every 6~8 months to prevent aging leakage; 2. Frequently bent pipes: Overall replacement every 10 months to avoid sudden fatigue cracking; 3. Pneumatic quick fittings: Annual sampling replacement for loose and blocked parts; 4. Full pipeline inspection: Complete aging consumable replacement during annual equipment overhaul.
