ⅠHigh-Temperature Aging Test Chamber Design Features
1. Four removable wheels on the bottom facilitate movement and securement of the equipment. A multi-layered, insulated tempered glass observation window allows for continuous monitoring of test progress within the chamber.
2. The interior of the high-temperature aging test chamber and its accessories are constructed of stainless steel, extending the lifespan of the equipment and ensuring robust maintenance. Because the constant-temperature control system allows for testing with a temperature difference of 2% and a temperature fluctuation of 1°C, the interior of the equipment is a sealed space.
3. The high-temperature aging test chamber is equipped with various safety warning devices, including those for overtemperature, leakage, fan motor overheating, and short circuits. When the temperature exceeds the limit, it automatically shuts off to prevent accidents.
4. High-density, ultra-fine glass fiber insulation with a thickness of 12cm ensures a more uniform and stable temperature in the test equipment. Furthermore, the equipment temperature is not affected by external temperatures, nor does it affect the test temperature inside the chamber.
5. Considering the characteristics of high-temperature testing, the high-temperature aging test chamber uses a self-priming, high-temperature, high-pressure seal.
6. The internal circulation system utilizes a long-axis fan motor and a high- and low-temperature-resistant stainless steel multi-blade impeller to achieve vertical convection circulation, ensuring a more uniform and stable temperature in the test equipment.
7. Considering the possibility of external testing power cables or signal cables, the number of lead-in holes can be increased based on the testing needs of different customers.
8. To facilitate temperature regulation in the high-temperature aging test chamber, a dedicated air duct is installed inside the chamber, equipped with a heating system and inlet and outlet temperature circulation fans.
Ⅱ Choosing a High-Temperature Aging Test Chamber
1. Reproducibility of Environmental Conditions
The environmental conditions created by the high-temperature aging test chamber (including the platform environment) surrounding the test product should meet the environmental conditions and tolerance requirements specified in the product test specification.
2. Repeatability of Environmental Conditions
Test equipment may be used for multiple tests of the same product type, and a single test product may be tested in different environmental test equipment. To ensure comparability of test results obtained for the same product under the same test specification, the environmental conditions provided by the environmental test equipment must be repeatable.
3. Measurability and Controllability of Environmental Condition Parameters
The environmental conditions provided by the high-temperature aging test chamber must be observable and controllable. This is not only necessary to keep environmental parameters within a certain tolerance range and ensure reproducibility and repeatability of test conditions, but also essential for product testing safety to prevent errors caused by environmental conditions. Controlling the test product can damage it and cause unnecessary losses.
4. Exclusive Environmental Conditions
For every environmental or reliability test conducted, the equipment must strictly adhere to the categories, values, and tolerances of environmental factors. Environmental factors not required for the test must be excluded from the test. This ensures a reliable basis for determining and analyzing product failure and failure modes during and after the test. Therefore, environmental test equipment must not impose any additional environmental stresses on the test product beyond the specified environmental conditions.
5. Safety and Reliability of Test Equipment
During high-temperature aging chamber testing, test personnel frequently perform operations and testing around the site. Therefore, environmental test equipment must be safe, easy to operate, reliable, and have a long service life to ensure the smooth conduct of the test. The high-temperature test chamber's various protections, warning measures, and safety interlocks must be comprehensive and reliable to ensure the safety and reliability of test personnel, the test product, and the test equipment itself.
Ⅲ High-Temperature Aging Test Chamber Maintenance
1. If the chamber is not in use for an extended period, it should be powered on every two weeks for at least one hour.
2. Clean the condenser regularly (every three months): For air-cooled compressors, the condenser fan should be regularly inspected and the condenser cleaned and dusted to ensure proper ventilation and heat exchange performance. For water-cooled compressors, in addition to ensuring the water inlet pressure and temperature, the appropriate flow rate must also be maintained, and the condenser interior should be cleaned and descaled regularly to ensure continued heat exchange performance.
3. Clean the evaporator (dehumidifier) regularly (every three months): Due to the varying cleanliness levels of the test samples, the forced air circulation can cause dust and other small particles to condense on the evaporator (dehumidifier), so regular cleaning is recommended.
4. Cleaning and balancing the circulating fan blades and condenser fan: Similar to cleaning the evaporator, due to the varying operating environments of the aging test chamber, the circulating fan blades and condenser fan can accumulate dust and other small particles, so they should be cleaned regularly.
5. Cleaning the water system and humidifier: Blocked water systems and scale in the humidifier can easily lead to dry-burning, potentially damaging the humidifier. Therefore, regular cleaning of the water system and humidifier is essential.
6. After each test in the high-temperature aging test chamber, set the temperature close to the ambient temperature, operate for approximately 30 minutes, then disconnect the power supply and clean the interior walls of the chamber.
Ⅳ Metal Types Requiring High-Temperature Aging Tests
1. High-Temperature Alloys
High-temperature alloys are metal materials that exhibit excellent properties such as high strength, high hardness, high heat resistance, and high corrosion resistance under high-temperature conditions. These materials are commonly used in aviation, aerospace, rocket engines, and the nuclear industry. High-temperature aging test chambers can simulate these extreme environments to test the material's oxidation resistance, creep resistance, fatigue resistance, and other properties, providing important evidence for the research and development of high-temperature alloys.
2. Stainless Steel
Stainless steel is widely used in modern society, encompassing a wide range of applications including construction, furniture, kitchenware, appliances, and medical devices. High-temperature aging test chambers can simulate high-temperature environments to test the material's oxidation resistance, durability, and corrosion resistance, thereby assessing its service life and quality. The quality and performance of stainless steel have a significant impact on people's production and daily lives, and therefore, high-temperature aging tests play a crucial role in stainless steel testing.
3. Specialty Alloys
Specialty alloys are metal materials with specific properties, such as tungsten alloys, cobalt-chromium-molybdenum alloys, and nickel-based alloys. These materials are indispensable in fields such as shipbuilding, automotive, and military applications. High-temperature aging chambers can provide crucial support for the research and development of specialized alloy materials by testing their durability, tensile strength, and flexural strength under high-temperature conditions.
In summary, high-temperature aging chambers have a wide range of applications. In the future, as technology continues to advance, high-temperature aging chambers will continue to play a vital role in promoting material development and innovation.
