Free QuoteThe xenon aging test chamber uses a xenon arc lamp that can simulate the full sunlight spectrum to reproduce the destructive light waves existing in different environments, which can provide corresponding environmental simulation and accelerated tests for scientific research, product development and quality control, also known as "solar radiation protection test" According to the test standards and methods, it is divided into three types, air-cooled xenon lamp (LP/SN-500), water-cooled xenon lamp (LP/SN-500), desktop xenon lamp (TXE). , time, etc. It is an indispensable testing instrument in the aging test chamber series.
The xenon arc lamp that simulates the full sunlight spectrum to reproduce the destructive light waves existing in different environments can provide corresponding environmental simulation and accelerated tests for scientific research, product development and quality control.
The aging test is carried out by exposing the material sample to the light and thermal radiation of the xenon arc lamp to evaluate the light resistance and weather resistance of some materials under the action of a high temperature light source.

1. Ventilation cooling device: The temperature ventilation and cooling system of the test chamber is automatically controlled by the temperature controller, and the cooling system is used in the chamber to cool down.
2. The control blackboard thermometer adopts wired transmission technology, which effectively improves the control accuracy.
3. Optical fiber transmission is used to measure the radiation intensity of the xenon lamp to avoid the problem of measurement error caused by temperature.
4. A blackboard thermometer BPT quasi-thermometer is installed on the sample holder
5. Device: In order to record the working time of each test, the equipment is equipped with a timer on the operation panel, which can control the time of the equipment, and the equipment will automatically shut down when the timing is over.
6. Protection device: In order to make the xenon arc lamp work normally without damage, the xenon lamp will automatically go out when the door is opened, and the whole machine will stop working.
The control system is one of the most important systems of this equipment, with full touch screen controller, comprehensive electromagnetic compatibility design and humanized menu design, using the PLC program independently developed and written by the company and adaptive temperature control technology for temperature control, making the equipment operate Completely simplified, it solves the shortcomings of the previous PID control technology that requires multiple parameter settings and temperature overshoot, and the temperature control effect is excellent.
Blackboard temperature, air temperature, irradiation intensity, water spray time, spray stop time, accumulated irradiation energy, and the number of test cycles can be directly set and displayed.
Microcomputer intelligent control, after setting the temperature, the instrument controls the heating and heating power by itself and displays the heating state, and the temperature control is accurate and stable. Over-temperature alarm and automatically cut off the heating power. The touch operation is extremely user-friendly, and the man-machine correspondence effect is ideal.
The heating wire used at high frequency is very important in this system. The improperly selected heating tube has a short service life and is prone to short-circuiting of the funnel. It is extremely inconvenient and distressing for high-demand users and seriously affects the production inspection progress. For this reason, the company has developed the latest new type of ceramic heating frame. The ceramic material has high temperature resistance, good insulation, and will not cause leakage and short circuit. The heating wire imported from Germany is connected in the middle, with a thick wire diameter, high temperature resistance, and dry burning resistance. A quartz glass tube is placed in the middle of the heating wire. Its important function is to prevent the heating wire from becoming soft and falling down when it burns red, resulting in a short circuit between the heating wire and the metal of the inner box.
The main refrigeration components are selected from French Taikang compressors, using R404 and R23 DuPont environmentally friendly refrigerants respectively. After decades of testing and use, this brand of compressors has been proven to be the most stable refrigeration accessories for medium-sized equipment in the world. The compressor is fully enclosed, its structure is simple, but it is durable.
The expansion valve and electronic valve are the main components of the refrigeration system, all of which are made of Danfoss of Denmark, the oil separator and filter are made of American Emerson, and the refrigeration oil is the best American Ice Bear brand. The pipes used in the refrigeration system are all made of imported red copper material, which has the advantages of good flexibility, is not being easy to break, and has the best shock absorption effect for the long-term vibration characteristics of the refrigeration system.
1. Cooling method: air cooling
2. Refrigerant: environmentally friendly refrigerant R404A
1. Improved lubrication performance and lower piston temperature bring greater reliability;
2. The streamlined body improves airflow management; reduces pressure and improves refrigeration efficiency;
3. The top unloading valve provides continuous minimum discharge pipe pulse;
5. Use environmentally friendly refrigerants R23. R404A (excluding CFC) that are not prohibited by the Montreal Convention or the London Amendment
The humidification tube is as important as the heating tube. If the material is not selected properly, leakage and short circuit faults may occur, and if the humidity cannot be added, equipment failure may occur. At the same time, the humidification system is divided into internal humidification and external humidification. The internal humidification and humidification speed is fast, but it is also easy to drive the temperature of the inner box. If the temperature rises, the temperature control will be unstable and the accuracy will not be high. Therefore, the company adopts the external humidification structure, which has the advantage of stable speed and little effect on the incidental temperature of the inner box, thus ensuring stable temperature rise and ideal humidification effect. The most important thing is that the company's humidification tube adopts a U-shaped design plus an over-temperature probe hole, and the heating wire is also of the same imported brand as the heating system to ensure a long service life and long-lasting durability of the humidification tube.
The safety protection system is the most important for users, and setting up multi-layer protection is an important measure to protect users.
1. Phase sequence protection, three-phase power is prone to lack of phase or reversed line sequence, which can damage equipment or cause accidents to testers.
2. Leakage protection, the use of unqualified heating wires or humidification tubes are enough to cause electric shock accidents.
3. Over-temperature protection, the use of a controller with poor quality brand may cause the temperature to run out of control and cause a fire accident.
4. Abnormal protection, when a certain index of the equipment is abnormal, the equipment will automatically prompt the cause of the alarm and the solution, and at the same time suspend the operation of the equipment, and wait for the maintenance personnel to solve the problem before running.
