Water-cooled xenon lamp aging test chamber use requirements relative to the air-cooled to much higher, the need to use pure water machine, while the air-cooled type can use tap water for spraying. Pure water machine to create the water is mainly used to cool the lamp, if the water quality is not good, will produce scale, affecting the irradiance of the lamp. The use of xenon arc lamp can simulate the full sunlight spectrum to reproduce the destructive light waves that exist in different environments, can provide the corresponding environmental simulation and acceleration test for scientific research, product development and quality control, this xenon lamp aging test chamber for water quality requirements are very strict, if the equipment does not circulate the water, then a test down after the water consumption is also very high, such as recycling, then the water quality Changes in water quality and water temperature also need to pay attention to.
1, on the water-cooled xenon lamp aging tester spray water and humidification water used is also distilled water, if the use of ordinary tap water sample surface will appear white material wrapped in the surface of the sample, can not achieve the purpose of irradiation, this material is water impurities after evaporation called calcium and magnesium crystals, so this piece of distilled water is required to use to ensure the consistency of radiation, to achieve the purpose of the test.
2, for the xenon lamp aging tester lamp cooling water with deionized water, not unauthorized use of tap water, the strict requirements of the conductivity of 5us/cm or less, because the xenon lamp trigger produces a large current and high pressure, if the use of high conductivity of water, then the lamp trigger will cause damage to the lamp, the water inlet temperature must be below 35 ℃, because the water temperature is too high will also shrink the service life of the xenon lamp tube. So in the case of the use of recycled water but also closed chilled water system and filtration system to ensure that the water quality because of secondary pollution caused by cooling.
3, there is a point to be made is the voltage regulation of the power supply, which is very important, is a key factor that directly leads to the use of water-cooled lamps.
