How to Deal With Problems That May Occur During The Use Of UV Lamps

UV lamps are the core components of UV water sterilizers. If there are problems with the lamps during the operation of the UV water sterilizer, it may cause the device failing to work properly, thus affecting its efficiency. Here are some common problems with UV lamps and their possible solutions for your reference only.

1. UV lamp does not light up.
   • Check if the power supply is functioning properly.
   • Check if the lamp is intact and free from damage or leakage.
   • Check if the circuit connection is good to eliminate the possibility of poor contact.
2. Abnormal UV lamp emission.
   • Check if the power parameters of the lamp are correct to ensure they are compatible with the equipment requirements.
   • Check if the lamp has slow leakage and replace any damaged lamps.
   • Check if the lamp exhaust is thoroughly cleaned to ensure no impurities inside the lamp.
   • Check if the transformer is suitable and confirm stable output voltage.
3. There are patterns on the outer side of the UV lamp.
   • Avoid touching the lamp wall with your hands to prevent contamination and damage.
   • Ensure thorough cleaning of the quartz tube during lamp production.
4. The metal head of the UV lamp melts and burns out.
   • Check if the copper contact of the lamp holder is oxidized. If so, clean and repair it.
   • Check if the spring has sufficient elasticity to ensure good contact.
   • Pay attention to the firm contact between the lamp base and the lamp holder during new lamp installation.
5. The UV lamp suddenly cracks.
   • Check if the current is too high. If there are issues like short circuits in the circuit, repair the circuit.
   • Avoid dirty objects hitting the lamp wall when sucking air.
   • Check if the electrode sealing is good to avoid damage and rupture.
6. UV lamp produces fog.
   • If there is fog inside the lamp, it may be due to the material of the quartz tube or the exhaust process. It is necessary to replace an appropriate quartz tube or optimize the exhaust process.
   • If there is fog outside the lamp, it may be ink or varnish volatiles adhering to the tube wall, which can be cleaned with solvent.
7. UV lamp deformation.
   • Check if the temperature is too high and ensure that the fan and exhaust duct are unobstructed.
   • Severe deformation may cause the lamp wall to become thinner and rupture, so it should be replaced in time.
8. Both ends of the UV lamp turn black.
   • The blackening may be caused by the peeling of electrode powder and its attachment to the tube wall, which is a normal phenomenon before the end of its lifespan.
