Twelve major problems that often occur with UV lamps

1. What is the reason for the fogging of UV lamps? If there is fog in the tube, it is:
a. Quartz tube problem.
b. The exhaust is not good during the production process.
c. The purity of the gas charged is not enough.
If there is fog outside the tube, it means that the gas volatiles of ink and varnish are attached to the wall of the tube, which can be wiped regularly with solvents such as alcohol.

2. The main reason for the deformation of the UV lamp, what are the adverse reactions after the deformation?

The main reason for the deformation of the UV lamp is that the temperature is too high. Slight deformation will not affect normal use, but the life will be shortened a lot.

Severe deformation will make the wall of one side of the lamp thin and rupture. Check whether the fan is damaged or the exhaust duct is too long and the exhaust is not smooth.

3. What is the matter with the adsorption of crystals in the UV lamp tube?

In the process of UV lamp production, the quartz tube is not clean and there are impurities.

4. What is the matter with the UV lamp deformed into a bubble and burst?

If the local temperature is too high, or the quartz tube wall is too thin, check whether the exhaust system is unobstructed.

5. What is the reason why the metal head of the UV lamp always melts and burns out?
a. The metal lamp frame has been used for a long time, the copper frame is oxidized, the local poor contact causes the current to be too large, and the ignition causes melting.
b. The melting of the new lamp is because the metal head of the UV lamp is in poor contact with the lamp holder, and the virtual connection causes the ignition to melt. Check whether the copper contacts of the      lamp holder are oxidized, and check whether the spring is elastic.

6. What is the reason why the UV lamp cannot be lit after a few hours of use (the lamp is intact)?

If it is a metal halide lamp, it is because the halide ratio is not appropriate, or the output of the transformer is too low, or the tube voltage of the lamp is too high. If it is a mercury lamp, it may be the cause of the      electrode or the inherent quality of the lamp, or the lamp has leaked.

7. What's the matter with the blackening of both ends of the UV lamp?

It is the electrode powder that peels off and adheres to the tube wall, but the service life is normal, and it is abnormal if it is used for one to two hundred hours.

8. What is the reason for the sudden exposure of the UV lamp during use?
a. Excessive current (such as short circuit of capacitor line).
b. Dirt hits the pipe wall when inhaling.
c. Poor sealing of electrodes such as molybdenum and platinum.

9. What is the reason why the UV lamp always has a pressure drop during use and cannot be recovered?
a. Excessive ventilation.
b. The temperature of the cold end electrode does not come up.
c. The electrical parameters of transformers, capacitors and lamps do not match.
d. The network voltage is too low, causing the transformer output voltage to be too low.

10. After using the UV lamp for 300-500 hours, why is there a pattern like a hand pattern on the tube wall?
a. Touching the wall of the lamp tube by hand during installation will cause this phenomenon.
b. When there is a UV lamp tube on the inside of the wall, the quartz tube is not cleaned enough.

11. The current and voltage of the UV lamp are normal, but the light is not normal and the light is green and yellow. What is the reason?
a. The lamp power parameters are incorrect.
b. The lamp tube has a slow leakage phenomenon.
c. The exhaust of the lamp tube is not clean when it is made.
d. The transformer configuration is small.

    
12. The first time the UV lamp can be turned on and off normally, but it can't be lit again, what's the matter?
If the capacitors and transformers are in good condition, and the lines are unblocked, and there is no bad contact (there is voltage at both ends of the lamp), the lamp itself is the problem, usually the electrode        is faulty, or the lamp has leaked.
