Wuhan Xenon Lamp Aging Test Chamber

Wuhan Xenon Lamp Aging Test ChamberCirculating system:
The water spray function of the xenon lamp aging test chamber can reproduce the impact of these environmental conditions on materials. The infrared radiation emitted by the lamp tube inside the xenon lamp aging test chamber can reconstruct the heat accumulation process, while the cold water spray produces a temperature fluctuation effect. During the rainwater spraying cycle, temperature is not controlled. The water quality of the spray circulation system adopts ionized water (solid content less than 20ppm), with water level display in the storage tank. Two nozzles are installed on the top of the working room, and the sprayed water is recyclable. The spray pressure can be adjusted between 0.12 and 0.15Mpa. The heating system of the xenon lamp aging test chamber adopts a far-infrared nickel chromium alloy high-speed heating electric heater; Independent systems for high temperature, humidity, and lighting (non interfering with each other); The temperature control output power is calculated by a microcomputer to achieve high-precision and high-efficiency electricity efficiency.

Water level and light source adjustment method:
When the surface of the test cloth is not clean or hardened, the test cloth must be replaced. The test cloth should be replaced about every three months. When replacing, the temperature measuring body should be wiped with a clean cloth. When replacing the new test cloth, hands should be cleaned first. The position of the weather resistant water accumulation cylinder of the xenon lamp should not be too high, which may cause water to overflow. If the water accumulation cylinder is too low, it may cause the wet bulb test cloth to absorb water abnormally, affecting the accuracy of the wet bulb. The water level should be kept about six tenths full. The adjustment of the water level in the water tank can adjust the height of the water tank. The rotating frame and motor of the xenon lamp aging test chamber are driven by a clutch, which allows the rotating frame to rotate flexibly and easily clamp the sample without the need for a jog function; It also has a built-in water storage tank and water connection to automatically control the water intake and is equipped with a filtering device, without burning out the water pump or blocking the atomizer due to water shortage. Equipped with an independent timing function for the sample holder, samples can be placed at different times, greatly saving testing costs In arc discharge, the energy lost due to elastic collision between electrons and gas is inversely proportional to the atomic weight of the gas. Therefore, compared with other inert gases, xenon arc discharge has smaller losses and higher luminous efficiency. At the same time, xenon gas has a lower ionization potential, resulting in a smaller voltage drop around the electrode during discharge, which can extend the lifespan of the electrode. Due to the unique atomic structure of xenon, the spectrum emitted by a long arc xenon lamp is very similar to that of sunlight, which is a characteristic of xenon lamps. The power of the xenon lamp weathering test chamber is limited and is generally made between 5 and 100 watts. The power of xenon lamps can range from 10000 watts to several hundred thousand watts.
