What are the nine operational notes for the thermal shock test chamber? Do you know what?
Â
The thermal shock test chamber is suitable for testing quality of electronics, electrical appliances, instruments, food, vehicles, metals, chemicals, building materials, aerospace, medical, and products. There are many precautions in the operation of the thermal shock test chamber. It is known that these precautions can work better in the cold and hot shock test chamber!
Â
1. It should be avoided as much as possible to start and stop the thermal shock test chamber frequently (do not start the operation again within five minutes after the cold shock test chamber is stopped), so as to avoid increasing the mechanical load of the refrigeration system compressor and affect the service life of the unit.
Â
2. It is strictly forbidden to test flammable, explosive, volatile and corrosive items in the thermal shock test chamber. Otherwise, the machine will be damaged or the test result will be invalid.
Â
3. The amount of test object placed does not affect the balance and smoothness of the airflow in the studio, otherwise it will affect the performance of the thermal shock test chamber and the authenticity of the test. On any section perpendicular to the direction of the inner circulation airflow, the sum of the areas of the test object should not be greater than 1/3 of the cross-sectional area of ​​the working chamber.
Â
4. Hao Tian. Before the operation of the thermal shock test chamber, the test chamber door should be closed and closed, otherwise the studio gas will be leaked and the test will not meet the performance requirements.
5. Personnel should be designated to operate the thermal shock test chamber to avoid unnecessary damage caused by improper operation.
Â
6. If the cold and hot shock test box is tested under low temperature conditions below 0 °C, the test box door should be avoided as much as possible. Because when the low temperature test is run, if the door is opened, the evaporator of the refrigeration system and other parts will be frosted, especially When the test temperature is lower, the condition is more serious. If the door must be opened, the door opening time should be shortened as much as possible.
Â
7. After using the thermal shock test chamber to complete the low temperature test operation, be sure to set the test temperature condition to 30 ° C for about half an hour after drying (back to normal temperature, the temperature controller can set the automatic function) and then stop the test. The door is subjected to operations such as picking up and placing test articles to avoid affecting the test performance of the next working condition.
Â
*If the drying process is not carried out at 30 °C, the machine will malfunction
Â
8. When the hot and cold shock test chamber is running at high temperature and high humidity, it is strictly forbidden to open the door unless necessary. Otherwise, the following adverse consequences may result:
Â
High-temperature wet gas rushes out of the test chamber and is prone to burns! The inside of the door, the test area and the surface of the sample still maintain a high temperature, which is easy to burn your hands! High temperature air may trigger a fire alarm and cause malfunction! Cold and thermal shock test box door opening operation: When the operator opens the door, it must move backwards along the test box door along the opening direction to prevent the machine from injecting a large amount of hot air in the test box just after running the high temperature test.
Â
9. During the operation of the thermal shock test chamber, do not touch the machine system components with your hand to avoid electric shock or motor damage. Therefore, please stop the machine and turn off the power before repairing.
