High-temperature aging room troubleshooting method

High-temperature aging room troubleshooting method High-performance electronic products have to pass the simulation of high temperature and harsh environment testing, in order to improve product stability, reliability, high-temperature aging room is this ideal experimental instrument. Mainly used in power electronics, computers, communications, biology and other fields. When the high-temperature aging room is used, there are mainly the following types of failures: In the high-temperature test, if the temperature does not reach the test temperature, the electrical system can be checked and the failures can be eliminated one by one. If the temperature rises very slowly, it is necessary to look at the air circulation system and see if the adjustment baffle of the air circulation is turned on normally. On the contrary, check whether the motor operation of the air circulation is normal. If the temperature overshoots badly, then you need to set the PID setting parameters. If the temperature rises directly, over-temperature protection, then the controller fails and the control instrument must be replaced. If the low temperature does not reach the test index, then you must observe the temperature change, whether the temperature drop is very slow, or whether the temperature rises after the temperature reaches a certain value. The former must check whether it will be the studio before the low temperature test. After drying, the test chamber is kept dry, and then the test sample is placed in the work chamber and tested again. The test chamber in the work chamber is placed too much, so that the air in the work chamber cannot be fully circulated. In the heat and humidity test, the actual humidity will reach 100% or the actual humidity and the target humidity will be very different. The value is much lower. The former phenomenon may be caused by dry gauze on the wet-bulb sensor. Then check the wet-bulb sensor. Whether the water in the sink is short of water, the water level in the water tank is controlled automatically by a water level controller, check whether the water supply system of the water level controller is normal, and whether the water level controller is working properly. Another possibility is that the wet ball gauze may cause the gauze to become hard due to the long use time or the purity of the water supply, so that the gauze cannot absorb the moisture and dry, and the above phenomenon can be eliminated only by replacing or cleaning the gauze. The latter phenomenon is mainly because the humidification system is not working. Check the water supply system of the humidification system. Check whether there is a certain amount of water in the water supply system. Control whether the water level of the humidifying boiler water level is normal and whether the water level in the humidifying boiler is normal. When the equipment suddenly fails during the test operation, a corresponding fault display prompt appears on the control instrument and there is a voice alarm. 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.
