Air-cooled xenon aging chamber common failure maintenance techniques

The air-cooled xenon aging chamber adopts xenon arc lamp which can simulate the full sunlight spectrum to reproduce the destructive light waves existing in different environments. This equipment can provide corresponding environmental simulation and acceleration test for scientific research, product development and quality control.

 

The air-cooled xenon aging chamber can be used for tests such as selection of new materials, improvement of existing materials or evaluation of changes in durability after changes in material composition. The equipment can well simulate the changes in materials exposed to sunlight in different environmental conditions. The equipment measures the lightfastness of materials by exposing them to ultraviolet (UV), visible and infrared light.

It uses a filtered xenon arc lamp to produce a full sunlight spectrum with a large match to sunlight. The use of a reasonably filtered xenon arc lamp is a way to test the sensitivity of a product to the longer wavelength bands of UV and visible light in direct light or in sunlight through glass. When you expose the product to direct sunlight outdoors, the time of day when the product experiences large light intensity exposure is just a few hours.

 

Air-cooled xenon lamp aging box refrigeration system common failures

 

1, xenon lamp aging box refrigeration system blockage

 

Xenon lamp aging box refrigeration system from the degree of blockage, divided into half blockage, full blockage; from the reasons for blockage is divided into dirty plug, ice plug and welding plug. Generally speaking, easy to plug the components of the capillary tube and filter. If the refrigeration system is half blocked, the pressure of the gas side of the connecting tube will be very low, the blocked part may have frost, and the temperature difference between the front and rear is very large; if the full blockage occurs, the gas side of the tube pressure is negative pressure, the compressor current is very small, the compressor exhaust pipe welding blockage, the compressor current is very large.

 

2, xenon lamp aging box refrigeration system leakage

 

When the xenon lamp aging box refrigeration system leakage, due to the reduction in the amount of refrigerant, the xenon lamp aging box refrigeration system compressor current is small. Refrigeration, capillary tube, liquid side tube may frost. The temperature of the gas side tube is high and may be undoubtedly exposed. When heating, the compressor discharge tube temperature is too high may scorch the gas-side insulation sleeve tube. Usually, the leak at the oil, available alkaline water leak detection.

 

3, xenon lamp aging box refrigeration system compressor failure

When the air-cooled xenon lamp aging box refrigeration system compressor voltage input and not running, the compressor case can be touched by hand. If it is very hot, it may be disconnected from the overload protector, and if the case is cooled, the compressor is still disconnected between the terminals or the resistance value does not match the calibration value, the compressor should be replaced. When the compressor starts and stops frequently, it should check whether the indoor and outdoor heat is normal and whether the distribution capacity is sufficient.
