UV aging tester testing equipment
The structure of the test chamber is made of corrosion-resistant metal materials, including 8 fluorescent ultraviolet lamps, a water tray, a test sample holder, and temperature and time control systems and indicators.
2. The lamp power is 40W and the lamp length is 1200mm. The range of the uniform working area of the test box is 900 × 210mm.
3. The lights are installed in four rows, divided into two rows. The tubes of each row of lights are installed in parallel, and the center distance of the lights is 70mm.
4. The test sample is fixedly installed at a position 50mm away from the surface of the lamp surface. The test sample and its bracket form the inner wall of the box, and their backs are exposed to cooling air at room temperature due to the temperature difference between the test sample and the air inside the box. To create stable condensation conditions on the surface of the test sample during the condensation stage, the test chamber should generate natural air convection through the outer wall of the chamber and the channel of the test sample at the bottom.
5. Water vapor is generated by a water tray located at the bottom of the heating box, with a water depth not exceeding 25mm, and equipped with an automatic water supply controller. The water tray should be regularly cleaned to prevent the formation of scale.
6. The temperature of the test chamber is measured by a sensor fixed on a black aluminum plate (blackboard) with a width of 75mm, height of 100mm, and thickness of 2.5mm. The blackboard should be placed in the central area of the exposure test, and the measurement range of the thermometer is 30-80 ℃ with a tolerance of ± 1 ℃. The control of lighting and condensation stages should be carried out separately, and the condensation stage is controlled by the heating water temperature.
7. The test chamber should be placed in a test room with a temperature of 15-35 ℃, 300mm away from the wall, and should prevent the influence of other heat sources. The air in the test room should not circulate strongly to avoid affecting the lighting and condensation conditions.

Structural characteristics of temperature and humidity control box
The full name of the temperature and humidity control chamber is "Constant Temperature and Humidity Test Chamber", which is an essential testing equipment in aviation, automotive, home appliances, scientific research and other fields. It is used to test and determine the parameters and performance of electrical, electronic and other products and materials after high temperature, low temperature, humidity and heat or constant temperature environment changes. It can be mainly divided into "desktop" and "vertical" according to testing requirements and standards, with the difference being the temperature and humidity that can be achieved. The vertical type can be used for low temperature and drying below room temperature, while the desktop type can only be used for temperature and high humidity above room temperature.
Suitable for various small electrical appliances, instruments, materials, and components for wet heat testing, it is also suitable for conducting aging tests. This test chamber adopts the most reasonable structure and stable and reliable control method currently available, making it aesthetically pleasing, easy to operate, safe, and with high precision in temperature and humidity control. It is an ideal equipment for conducting constant temperature and humidity tests.
1) The test box body is in the form of an integral structure, with the refrigeration system located at the lower rear of the box and the control system located at the upper part of the test box.
(2) Inside the air duct interlayer at one end of the studio, there are devices such as heaters, refrigeration evaporators, and fan blades distributed; On the left side of the test box, there is a Ø 50 cable hole, and the test box is a single door (stainless steel embedded door handle)
(3) The double-layer high temperature and anti-aging silicone rubber seal can effectively ensure the temperature loss of the test chamber

UV accelerated aging testing machine with humid condensation environment and water spray system
In many outdoor environments, materials can be kept moist for up to 12 hours per day. Research has shown that the main factor causing outdoor humidity is dew, not rainwater. GUV simulates outdoor moisture erosion through its unique condensation function. In the condensation cycle during the experiment, the water in the reservoir at the bottom of the testing chamber is heated to generate hot steam, which fills the entire testing chamber. The hot steam maintains the relative humidity in the testing chamber at 100% and maintains a relatively high temperature. The sample is fixed on the side wall of the testing chamber, so that the testing surface of the sample is exposed to the ambient air inside the testing chamber. The outward side of the sample exposed to the natural environment has a cooling effect, resulting in a temperature difference between the inner and outer surfaces of the sample. The occurrence of this temperature difference causes the sample to always have liquid water generated by condensation on its testing surface throughout the entire condensation cycle.
Due to outdoor exposure to moisture for up to ten hours a day, a typical condensation cycle typically lasts for several hours. GUV provides two methods for simulating humidity. The most commonly used method is condensation, which is the best way to simulate outdoor moisture erosion. All GUV models are capable of running condensation cycles. Because some application conditions also require the use of water spray to achieve practical results, some GUV models can operate both condensation cycle and water spray cycle.
For certain applications, water spray can better simulate the environmental conditions of final use. Water spraying is very effective in simulating thermal shock or mechanical erosion caused by temperature fluctuations and rainwater erosion. Under certain practical application conditions, such as sunlight, when the accumulated heat rapidly dissipates due to sudden showers, the temperature of the material will undergo a sharp change, resulting in thermal shock, which is a test for many materials. GUV's water spray can simulate thermal shock and/or stress corrosion. The spray system has 12 nozzles, with 6 on each side of the testing room; The sprinkler system can run for a few minutes and then shut down. This short-term water spray can quickly cool the sample and create conditions for thermal shock.

The observation window adopts multi-layer hollow tempered glass, and the inner adhesive sheet conductive film is heated and defrosted. The lighting fixtures adopt imported brand Philips lamps, which can effectively observe the experimental changes in the studio from all angles.
The refrigeration cycle of the temperature and humidity control box adopts the reverse Carnot cycle, which consists of two isothermal processes and two adiabatic processes. The process is as follows: the refrigerant is adiabatically compressed to a higher pressure by the compressor, and the work consumed increases the exhaust temperature. Then, the refrigerant exchanges heat with the surrounding medium through the condenser and transfers heat to the surrounding medium. After the refrigerant undergoes adiabatic expansion through the shut-off valve, the temperature of the refrigerant decreases. Finally, the refrigerant absorbs heat from the object at a higher temperature through the evaporator, causing the temperature of the cooled object to decrease. This cycle repeats itself to achieve the goal of cooling down.
The refrigeration system design of this test chamber applies energy regulation technology, which can ensure the normal operation of the refrigeration unit and effectively adjust the energy consumption and refrigeration capacity of the refrigeration system, so as to maintain the refrigeration system in the optimal operating state. By using Balanced Temperature Control (BTC), the control system automatically calculates the output of the heater based on the set temperature point through PID calculation when the refrigeration system is working continuously, ultimately achieving a dynamic balance.

Maintenance of refrigeration compressor for constant temperature and humidity test chamber, cold and hot shock test chamber
Article summary: For environmental monitoring equipment, the only way to maintain long-term and stable use is to pay attention to maintenance in all aspects. Here, we will introduce the maintenance of the compressor, which is an important component of the constant temperature and humidity test chamber and the cold and hot shock test chamber
Detailed content:
Maintenance plan for refrigeration compressor:
As the core component of the refrigeration system in the constant temperature and humidity test chamber, the maintenance of the compressor is essential. Guangdong Hongzhan Technology Co., Ltd. introduces the daily maintenance steps and precautions for the compressor in the constant temperature and humidity test chamber and the cold and hot shock test chamber
1、 Carefully check the sound of the cylinders and moving parts at all levels to determine if their working condition is normal. If any abnormal sound is found, immediately stop the machine for inspection;
2、 Pay attention to whether the indicated values of pressure gauges at all levels, pressure gauges on gas storage tanks and coolers, and lubricating oil pressure gauges are within the specified range;
3、 Check if the temperature and flow rate of the cooling water are normal;
4、 Check the supply of lubricating oil and the lubrication system of the moving mechanism (some compressors are equipped with organic glass baffles on the side of the cross head guide rail of the machine body),
You can directly see the movement of the crosshead and the supply of lubricating oil; The cylinder and packing can be inspected for oil discharge using a one-way valve, which can check if the oil injector is inserted into the cylinder
Oil injection situation;
5、 Observe whether the oil level in the body oil tank and the lubricating oil in the oil injector are below the scale line. If they are low, they should be refilled in a timely manner (if using a dipstick, stop and check);
6、 Check the temperature of the intake and exhaust valve covers at the cross guide rail of the crankcase with your hand to see if it is normal;
7、 Pay attention to the temperature rise of the motor, bearing temperature, and whether the readings on the voltmeter and ammeter are normal. The current should not exceed the rated current of the motor. If it exceeds the rated current, the cause should be identified or the machine should be stopped for inspection;
8、 Regularly check whether there are any debris or conductive objects inside the motor, whether the coil is damaged, and whether there is friction between the stator and rotor, otherwise the motor will burn out after starting;
9、 If it is a water-cooled compressor and water cannot be immediately supplied after the water is cut off, it is necessary to avoid cylinder cracking due to uneven heating and cooling. After parking in winter, the cooling water should be drained to prevent freezing and cracking of the cylinder and other parts;
10、 Check whether the compressor vibrates and whether the foundation screws are loose or detached;
11、 Check whether the pressure regulator or load regulator, safety valve, etc. are sensitive;
12、 Pay attention to the hygiene of the compressor, its associated equipment, and the environment;
13、 Gas storage tanks, coolers, and oil-water separators should regularly release oil and water;
14、 The lubricating machine used should be filtered by sedimentation. Differentiate the use of compressor oil between winter and summer
