A, UV lamp has generated mist What are the reasons? If it is there mist control is: (1) quartz tube, that is, from hydroxyl bad. (2) or in the production process exhaust bad. (3) Then filling into enough gas purity. If it is outside the control mist is: ink, varnished volatile gas attached to the wall, the regular use of alcohol solvent擦试.

 Second, UV light the main reason for deformation, deformation of adverse reactions after what? UV light is mainly due to the deformation temperature is too high, a slight deformation does not affect the normal use, but will shorten the life of many serious deformation of a side wall lamp will thinning and rupture. Check whether the fan exhaust pipe is too long or damage caused by poor ventilation.

 Third, UV lamp, there are a piece of crystal adsorption how the matter? UV lamp making process, the quartz tube cleaning unclean have impurities.

 Fourth, UV lamp change the formation of bubble, the bursting of how going on? Is the local temperature is too high, or because too thin quartz wall partially caused by the exhaust system to check whether the patency.

 5, UV lamp melting metal head always burn What are the reasons?

 a) metal Stands Over time, copper oxide planes, and local currents caused by poor contact is too large, brand caused by melting.

 b) a new lamp is melting because the UV light metal head and Stands bad, virtual access caused by melting brand. Stands to check whether the oxidation of copper contact to check whether there are elastic springs.

 6, UV lamp will not light up the use of a few hours (lights intact) What are the reasons? If it is metal halide is inappropriate because the degree of halide ratio, or the output transformer is too low, or too high pressure tube lights . If the mercury electrode is probably the reason for the intrinsic quality or lamp, or lights have been flat.

 7, UV lights at both ends of how black is going on? Is peeling powder electrode, attached to the wall, but life is normal use, use 1-200 hours, there is not such a situation to normal. 8, UV lights suddenly exposed in the use of crack what are the reasons? A) current is too large (such as short circuit capacitance)

 b) when the wind suction dirt hit the wall.

 c) platinum electrode, such as molybdenum bad seal.

 9, UV lamp is always pressure drop in the use of the process, not how recovery is going on?

 a) excessive exhaust b) cold junction temperature上不来electrode.

 c) transformers, capacitors and lamp electrical parameters do not match.

 d) the network voltage is too low, resulting in low output voltage transformer.

 10, UV lamps use 300-500 hours later, why the phenomenon of the wall on the same hand stria pattern? A) the installation of lights, when his hands touched the wall will use into this phenomenon.

 b) the inside wall there is so light, the quartz tube cleaning net enough.

 11, UV lamp current and voltage are normal, but the light-emitting abnormal, bleak was green yellow Why?

 (1) Lamp power parameters wrong.

 (2) tubes are slow leakage phenomenon.

 (3) lamp in the production does not exhaust the net.

 (4) with smaller transformers.

 12, UV lamp lit the first time to a normal shutdown, but no points after not matter how bright it is? If capacitors and transformers are in good condition, and the line is smooth, not bad phenomena (at both ends of lamp voltage ), the lamp is its own problems, usually electrode problems have been flat or lights.
