First, the UV lamp does not light up.
When the UV lamp is in use, sometimes the lamp does not light up, and sometimes it is bright. This is because the fluorescent ultraviolet aging test chamber generally uses electronic ballasts, and the electronic ballasts are wired. Therefore, some cases are not handled well because of the details of the manufacturing process, which leads to an unreliable hidden danger in the connection of the lamp corner to the electronic ballast. In the future use, of course, there is a problem of intermittent off-line, poor contact, and the like.
Second, the UV lamp has two hair black.
This is because the lamp of the UV lamp is tungsten, its melting point is 3410 ° C, when we illuminate the lamp, the temperature is between 2000 and 3000 ° C, the filament will not melt, sublimation will occur, then the sublimation of tungsten The vapor encounters the wall and solidifies into solid tungsten, which turns black, while the filament of the UV lamp is at both ends of the tube, so only the two ends turn black. When the UV lamp begins to turn black, it needs to be replaced. Therefore, in order to better extend the life of the lamp, the instrument does not think that the lamp should be turned on and off frequently. According to the standard, the lamp should not be turned off within 3 hours after the lamp is turned on.
Third, the ultraviolet sink is rusted.
The water tank of the UV aging test chamber is used to hold water for heating to simulate a natural night condensing environment. Since the water tank is made of stainless steel, when the equipment is used, if the user does not test the method of adding deionized water, the tap water is added. This will cause the sink to be corroded by the material formed by the heating of the water and the water after it has been used for about 3 years, causing the sink to rust until the sink is rusted.
Fourth, the sink heating tube replacement is frequent.
Because the deionized water is not used as specified, the heating pipe is immersed in tap water and high temperature tap water for a long time. We all know that the heating tube is made of stainless steel tube filled with magnesium powder. Therefore, long-term heating work in tap water causes the stainless steel on the surface of the heating pipe to be corroded and rusted.
Fifth, the instrument failure rate is high.
The instruments of the UV aging test chamber are installed at the top of the equipment, so there is a problem: when the equipment is heating (sometimes a test will be done for a few days, even weeks, the laboratory temperature can reach 60 ° C) and Some laboratories do not install air conditioners, and the hot air is rising upwards, so the meter will suffer from high temperature for a long time. In this high temperature environment, the instrument is prone to failure.
