Comprehensive analysis of troubleshooting methods for high and low temperature damp heat test boxes

When the user is using a high-low temperature damp heat test box, the following symptoms may appear. As an amateur, how do you deal with the failure of the alternating heat and humidity test box in an emergency? Below by the test box expert for your comprehensive analysis, if you need help, you can also contact 13538336510.

Troubleshooting treatment of high and low temperature heat chamber, please refer to the following text:

1, when the high temperature humidity test, occurrence of an actual humidity will reach 100% humidity and the set humidity or the actual vary greatly, a lot of low value, the former phenomenon: the gauze may be caused by dry wet bulb sensor, then To check whether there is water shortage in the water tank of the wet bulb sensor, the water level in the water tank is automatically controlled by a water level controller, and whether the water level controller water supply system 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 due to the fact that the humidification system of the test chamber is not working, check the water supply system of the humidification system, 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. If all of the above are normal, then you must check the electrical control system. This should be done by a professional maintenance personnel . You can contact 13538336510 .

2, when the high temperature test, such as temperature changes reach the test temperature, the electrical system can be checked, one by one troubleshooting. If the temperature of the test chamber rises very slowly, it is necessary to check the air circulation system to see if the adjusting baffle of the air circulation is turned on normally, otherwise, 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.

3. 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 chapter of the operation of the equipment, and then 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.

4, when the low temperature test box reach the set indicators trial, it would have to observe the changes in temperature, the temperature drop is very slow, to a certain temperature or temperature tends to increase the value of the former we must check, do 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 put into the work chamber and then tested. Whether the test sample in the work chamber is placed too much, the wind in the work chamber cannot be fully circulated, and is eliminated. After the above reasons, it is necessary to consider whether it is a fault in the refrigeration system. In this case, the manufacturer's professional personnel must be inspected and repaired. The latter phenomenon is caused by the poor use environment of the test chamber equipment. The ambient temperature of the equipment and the location of the equipment (the distance between the cabinet and the wall) must meet the requirements (in the equipment operation instructions).

The above is about the troubleshooting of the high-low temperature damp heat test box. The Kewen Xiaobian hopes to help you. If your damp heat test box is not the above phenomenon, please contact 13538336510. We will analyze the high and low temperature for you. Damp heat test box failure causes and solutions.
