Analysis of the 4 most common failures of UV Aging Test Chamber

UV Aging Test Chamber is to use a fluorescent UV lamp as the light source to perform accelerated weathering test on materials by simulating UV radiation and condensation in natural sunlight to obtain the results of material weathering resistance. It can simulate UV, rain, high temperature, high humidity, condensation, darkness and other environmental conditions in natural climate, and by reproducing these conditions, combine them into one cycle and let it automatically perform to complete the cycle times.

UV Aging Test Chamber common failure analysis:

1, the instrumentation failure rate is high. Fluorescent UV Aging Test Chamber instruments are installed on the top of the equipment, so there is a problem: in the equipment for heating work (sometimes a test will do a few days, or even weeks, the laboratory temperature can reach 60 ℃) and some laboratories do not install air conditioning, and the heat is going up, so the instrument will suffer the ravages of high temperature for a long time, in this high-temperature environment, the instrument is prone to failure.

2,, the water tank heating tube replacement frequently. Because there is no deionized water as required, so the heating tube long-term immersion in tap water, high-temperature tap water. We all know that the heating tube is made of stainless steel tube filled with magnesium powder. So long-term heating work in tap water, will lead to corrosion of the surface of the heating tube stainless steel, rust stains.

3, UV lamp tube blackened at both ends. This is because the head of the UV lamp is tungsten, its melting point is 3410 ℃, when we light the lamp, the temperature is between 2000 and 3000 ℃, the filament will not melt, sublimation will occur, then the sublimation of tungsten vapor meets the tube wall and condensed into a solid tungsten, making it black, and the UV lamp filament on the two ends of the lamp, so only the two ends become black. When the UV lamp starts to turn black, then it needs to be replaced. Therefore, in order to better extend the life of the lamp, please do not frequently start and shut down the lamp. According to the standard, do not turn off the lamp after the lamp is lit since less than 3 hours.

4, UV lamps do not light up. I know that the UV lamp in use, some times the lamp does not light up, some times the point of light. This is because the general use of fluorescent UV aging test chamber are electronic ballast, electronic ballast wiring for the jack type. So some times because of the details of the production process is not very good, which leads to the lamp corner line in the connection with the electronic ballast does not exist on the hidden danger. In the future use of course, the gap occurs in the off-line, poor contact and other problems.
