UV Accelerated Weathering Tester common 4 failure analysis

UV Accelerated Weathering Tester is suitable for the aging test of non-metallic materials against sunlight and artificial light.

1, UV sink rust through


The sink is used to fill with water for heating, simulating a condensing environment at night in nature. Sink is made of stainless steel, so in the use of equipment, if the user does not follow the prescribed method of adding deionized water to the test, but to join the tap water, will lead to the use of equipment after about 3 years, the formation of substances corroded by water heating, resulting in rusting sink, until the sink and other rust through.

2, ultraviolet lamp point does not light


UV lamps in use, some times the lamp does not light up. This is because the fluorescent UV aging test chamber is generally used are electronic ballasts, electronic ballasts are wired for the jack type. So limited by the details of the production process, it will lead to the lamp corner line in the connection with the electronic ballast there is a hidden danger of insecurity, the use of the gap will occur in the off-line, poor contact and other problems.

How to eliminate the safety hazards of xenon lamp test chamber? How to eliminate the xenon lamp test chamber safety hazards? xenon lamp test chamber has the following safety protection systems. 1. refrigeration system: leak detection test, compressor overheating, compressor overpressure; 2. Humidification system: heating tube dry burn, abnormal water supply, water shortage alarm; 3. Circuit system: over temperature protection, fan motor overheating, overall equipment under phase / reverse phase, overall equipment timing, leakage protection, overload and short circuit protection. When installing the xenon lamp test chamber, pay attention to the following points to ensure personal safety: 1. Power supply: The power supply of the equipment uses a three-phase five-wire system, and the equipment cable is four-core wire, three phase wires, and one neutral wire. Please pay attention to the distinction between neutral wires. Because part of the load and control system of the equipment is singl...

Tips for choosing an Ozone ageing chamber

图片
Tips for choosing an Ozone ageing chamber : The choice of environmental temperature: some products need to be tested in a temperature environment of minus degrees Celsius ozone resistance test, some are tested at room temperature, and some are tested at high temperatures. Users just need to understand their own products to test the common test temperature can be. It is important to note that testing at room temperature is more common. Conditions can be placed in the Ozone aging chamber premises equipped with air conditioning systems, it is recommended that users choose the test chamber with a refrigeration system when purchasing, to avoid the summer test, the temperature is too high resulting in inaccurate results. Chamber volume selection: because the Ozone aging chamber chamber materials and ozone concentration control accuracy difficulties will have a corresponding increase, so as long as the test products can be accommodated on, too large chamber will only cause waste.
