The rapid temperature change test chamber is used to test the performance of materials in various environments and to test the heat, cold, dry, and moisture resistance of various materials. The following will introduce three common problems and treatment methods for the rapid temperature change test chamber.
1. When the rapid temperature change test box suddenly fails during the test operation, the corresponding fault display prompt appears on the control instrument, and there is a voice alarm prompt. The operator can quickly check which type of fault belongs to in the troubleshooting section of the operation of the equipment, and the professional can quickly eliminate the fault to ensure the normal operation of the test. Other environmental test equipment will have other phenomena in use; it must be specific phenomena, specific analysis, and exclusion.
2. In the high temperature test, if the temperature change fails to reach the test temperature value, the electrical system can be checked and the faults can be eliminated one by one. If the temperature rises very slowly, it is necessary to look at the wind circulation system and see if the adjustment baffle of the wind circulation is normally open. Conversely, check whether the motor operation of the wind circulation is normal. If the temperature overshoots badly, then you need to set the PID setting parameters. If the temperature rises directly, the controller fails and the control instrument must be replaced.
3, Rapid temperature change test chamber can not reach the test index, then you have to observe the temperature changes; clearly, the temperature drop is very slow, or temperature has risen to a certain value after the temperature has risen. The former must check whether the studio is to be dried before the low temperature test, so that the studio is kept dry and then the test sample is placed in the work chamber and then tested. The test chamber inside the work chamber is placed too much, so that the work room The wind cannot be fully circulated. After eliminating the above reasons, it is necessary to consider whether it is a fault in the refrigeration system. In this case, the factory's professionals must be inspected and repaired. The latter phenomenon is caused by the poor use environment of the constant temperature and humidity chamber equipment. The ambient temperature of the equipment and the location of the equipment must meet the requirements.
Because of the time limit for use, the rapid temperature change test chamber with a long running time will inevitably lead to a variety of minor faults. Usually, attention is paid to regular maintenance and maintenance. Generally, most of them can be avoided. If you encounter a major technical problem, you can contact the manufacturer of the rapid temperature change test chamber in time to seek solutions.
