Comprehensive Guide to UV Lamp Fusing and Bending Issues: Causes, Solutions & Prevention
This article focuses on two common faults of UV lamps: fusing and bending. It briefly analyzes their causes and provides emergency treatment, repair points and long-term prevention measures, offering practical references for UV lamp use and maintenance.
- Electrical Contact Failure: Oxidation of copper contacts on lamp holders, insufficient spring force leading to poor connection and arcing, which melts the metal base; Low-quality terminals without silver/nickel plating cause excessive resistance and local overheating.
- Abnormal Current/Voltage: Power grid fluctuations (overvoltage/undervoltage), mismatched ballast and lamp power resulting in electrode overload; Capacitor short circuits causing instantaneous current surges.
- Product Defects: Inferior electrodes, thin sealing steel sheets, and frequent on-off cycles accelerate electrode sputtering and aging.
- Improper Operation: Short-interval repeated switching subjects electrodes to repeated current impacts; Restarting before complete cooling causes thermal fatigue.
- Shut down the system and close front/rear valves to contain contamination;
- Test mercury levels in water/air per EPA standards (0.002mg/L limit in US);
- Arrange professional cleanup; avoid contact with debris using regular cleaners.
| Failure Type | Inspection Focus | Remedial Measures |
| Metal Base Melting | Contact oxidation, spring tension | Replace with silver-plated terminals; clean contacts regularly |
| Electrode Burnout | Ballast matching, voltage stability | Use matching ballast; install voltage stabilizer |
| Frequent Fusing | On-off frequency, cooling time | Minimum 30-minute operation; 5-minute cooling before restart |
- Cooling System Failure: Damaged fans or blocked ducts cause overheating; uneven thermal expansion of quartz glass leads to bending;
- Material Quality Issues: Impure quartz glass with low heat resistance deforms under prolonged high temperatures;
- Manufacturing Defects: Uneven heating during production causes "snake-like bending"; improper shielding gas control during bending leads to shrinkage/expansion;
- Installation Stress: Misaligned mounting or vibration creates concentrated stress, accelerating deformation.
- Inspect cooling system: Clear duct obstructions and ensure unobstructed airflow;
- Replace with high-quality lamps: Choose high-purity quartz with straightness error ≤0.5mm;
- Adopt professional bending equipment: Use mold-limited machines with precise gas control.
- Selection Control: Prioritize lamps with uniform quartz tube roundness and thick sealing steel sheets; avoid ordinary glass substitutes;
- Environment Optimization: Maintain operating temperature at 20-40℃, humidity ≤60%; ensure proper ventilation to prevent ozone corrosion;
- Regular Maintenance: Clean lamp surfaces and contacts quarterly; replace aging ballasts annually;
- Professional Installation: Use shockproof mounts; ensure coaxial alignment of lamp and holder; avoid excessive force during installation.
