How to solve the failure of the high and low temperature test equipment -qinsun

I. What should I do if the temperature change does not reach the test temperature value in high temperature testing equipment?

The operator needs to check the electrical system and eliminate the failure one by one. If the temperature rises very slowly, check the wind circulation system to see if the adjustment baffle of the wind circulation is opened normally. On the contrary, check whether the motor of the wind circulation is normal. If the temperature is too strong, then the setting parameters of the PID need to be set up. If the temperature rises directly and the temperature is protected, the controller must be replaced by the controller.

2. In the damp -heat test of high and low temperature test equipment, why does the actual humidity reach 100%or the actual humidity is very different from the target humidity, and the value is much lower?

The phenomenon of the former of the former : It may be caused by the dry gauze on the wet ball sensor, then check whether the water is dehydrated in the sink of the wet ball sensor. The water level in the sink is automatically controlled by a water level controller. Whether the water level controller work is normal. Another possibility is that the damp ball gauze may harden the gauze due to the long period of use or the purity of water supply, so that the gauze cannot absorb the water and dry it. As long as it is replaced or cleaned, the above phenomenon can be excluded. The latter's phenomenon is that the humidification system does not work. Check the water supply system of the humidification system. Whether there is a certain amount of water in the water supply system, whether the water level control of the humidified boiler water level is normal, and whether the water level in the humidified boiler is normal. If everything above is normal, then check the electrical control system, which is requested to repair professional maintenance personnel.

3. What should I do if the low temperature test equipment does not reach the test index?

The operator needs to observe the change of temperature, whether the temperature drops slowly, or the temperature after the temperature to a certain value With a trend of recovery, the former must check whether to dry the studio before doing a low temperature test. After the studio keeps dry, put the test sample in the studio and then test it. Makes the wind in the studio not fully circulated. After excluding the above reasons, it is necessary to consider whether it is the failure in the refrigeration system, so that the manufacturer's professionals must be asked to repair it. The latter phenomenon is caused by the poor use environment of the device. The environmental temperature of the device is placed. The position of the placement (the distance between the back of the box and the wall) must meet the requirements (there are regulations in the instructions of the device operation).

Fourth, the high and low temperature test equipment suddenly failed during the test operation, the corresponding fault display prompts occurred on the control instrument and what to do with the alarm prompt? In the operation of operation and use, it can quickly check which type of failure is detected in chapters. You can ask professionals to quickly eliminate the failure to ensure the normal progress of the test.
