12 ultraviolet uv light common problem 2012-03-12

1. why have the fog to produce ultraviolet light?
In both cases, the second tube of the mist, mist tube head should be treated separately
(1) the possession of mist:
Quartz tube, ie decarboxylase bad.
* Or the exhaust is not good in the production process.
* Then there is no charge of gas purity.
(2) tube outside the fog: ink, varnish attached to the wall on the gas volatiles can smear the regular use of alcohol and other solvents.

2. under what circumstances will lead to the UV light deformation, deformation of the adverse consequences?
The reason: high temperature, a slight deformation does not affect the normal use, but life will be shortened a lot, cause thinning of the wall of the pipe end and the breakdown of serious distortion.
Solution: Check the fan exhaust pipe damage caused is too long or poorly ventilated.

3. why have a crystal adsorption under UV light?
Reasons: the decision-making process of the UV lamp, quartz tube cleaning does not clean the impurities.

4. why to change the UV lamp to form a similar bubble burst?
Reasons: because the local temperature of the quartz wall is too high, or too thin, due to local
Solution: Check the exhaust system is clear.

5. the UV lamp is always molten metal burns?
* Stand for a long time metal, copper oxide frame, causing the local contact current, ignition caused by melting.
* New lamp UV lamp head of molten metal is because of poor contact of the lighthouse, a virtual melting, resulting in ignition.

Solution: Check whether the copper oxide contact lighthouse, check whether there is a flexible spring.

6. The use of the sixth UV light, why can not light (lamp intact) a few hours?
According to the type of lights point of view
(1) metal halide lamps
Reason: halide ratio is inappropriate, or transformer output is too low or too high pressure lamp.
(2) mercury lamp
Reasons: because the electrodes or the intrinsic quality of the bulb or the lamp has been leaking.

7. Why are black at both ends of the UV lamp?
Analysis: peel powder electrode, attached to the wall, but life is normal use, the use of a two hundred hours, this situation is not normal.

8. why in the use of ultraviolet lights suddenly burst?
(1) current is too large (such as capacitors short circuit)
(2) breathing from time to time to play on the wall of dirt.
(3) molybdenum platinum electrode seal is bad.

9. the UV lamp is why always in the process of using the pressure drop does not rise?
(1) the exhaust is too large
(2) the cold end of the electrode temperature of
(3) transformers, capacitors and lamp electrical parameters do not match.
(4) the grid voltage is too low, causing the transformer output voltage is too low.

10. Why use 300-500 hours, ultraviolet light, the phenomenon of the hand model on the wall, like the model?
(1) wall installation will use light hand touch to this phenomenon.
(2) do the inside wall lamp, quartz tube cleaning is not enough to net.

11. the UV lamp current and voltage are normal, but the light is not normal, dull greenish yellow, why?

(1) power parameter is wrong.
(2) The light is slowly seeping.
(3) the net production of the exhaust pipe.
(4) using a small transformer.

12. UV light can light up close for the first time, but never a highlight of how not?

If the capacitor, the transformer is in good condition, and smooth lines, no bad behavior (the lamp voltage at both ends), the problem is the light bulb, the electrode is generally a problem, or the lamp has been compromised.
