These problems may occur in high and low temperature test chambers, do you know - [Information]

After working in the high and low temperature test chamber for a period of time, we may encounter various problems. So let me take you to see the possible problems in the high and low temperature test chamber. Do you know? I hope it can help you.

Problems related to high and low temperature test chambers

1. High and low temperature test chamber in high temperature test

1. For example, if the temperature change does not reach the test temperature value, we can check the electrical system and then troubleshoot the problem one by one.

2. If the temperature rises very slowly, we need to check the air circulation system to see if the air circulation adjustment baffle is turned on normally. On the contrary, we need to check whether the air circulation motor is running normally.

3. If the temperature is overshooting, you need to adjust the settings parameters of the PID.

4. If the temperature rises directly and is protected by overtemperature, if there is a problem with the controller, the control instrument needs to be replaced.

2. The low temperature of the high and low temperature test chamber does not meet the test indicators

1. You need to check the change of temperature, whether the temperature drops very slowly, or if the temperature reaches a certain value, the temperature will tend to rebound. Then check whether the studio needs to be dried before performing a low-temperature test, so that the studio can be kept dry and then put the test sample into the studio for testing. Whether the test samples in the studio are too much, resulting in the wind in the studio not being able to be fully circulated. After eliminating the above reasons, you need to consider whether there is a problem in the refrigeration system. In this way, people with professional and technical skills in the equipment manufacturer need to be inspected.

2. The subsequent phenomenon is caused by the poor application environment of the equipment. The ambient temperature and location of the equipment need to meet the requirements.

3. During the high and low temperature test chamber, the actual humidity will reach 100% or the actual humidity will be very different from the target humidity, and the value will be much lower. The former phenomenon:

1. It may be caused by the gauze on the wet bulb sensor being too dry. This requires checking whether there is water shortage in the sink of the wet bulb sensor. The water level in the sink is automatically controlled by a water level controller to check whether the water supply system of the water level controller is normal and whether the water level controller is working normally.

2. Another possibility is that the wet-ball gauze is used for too long or the purity of the water supply water quality will cause the gauze to become hard, which will make the gauze unable to absorb water and thus dry. Just replace or clean the gauze to eliminate the occurrence of the above phenomena.

3. The main phenomenon behind this is that the humidification system cannot 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 humidification boiler is normal, and whether the water level in the humidification boiler is normal.

4. If the above contents are normal, it is necessary to check the electrical control system. At this time, you need to ask a professional and technical maintenance staff to conduct inspection.

The above is the relevant content that may occur in the high and low temperature test chamber. Do you know the relevant content? I hope it will be of some help to you. During use, you must pay attention to the maintenance of high and low temperature test chambers, and regularly check and maintain the integrity of parts and components. Pay attention to applying anti-rust oil to parts that are prone to rust or accessories that are not used for a long time.
