Some problems may occur after the test equipment has been used for a period of time. The constant temperature and humidity test chamber is no exception. In addition, improper operation may cause malfunction when the test is performed. How can we solve these problems? Xiaobian introduced several common faults and treatment methods for everyone. Let's take a look.
1. The temperature does not reach the test temperature value during the high temperature test.
In this case, check the electrical system first, and then troubleshoot one by one. If the temperature rises in the constant temperature and humidity test chamber is too slow, it is necessary to check whether the adjustment plate of the air circulation system is normal; if the temperature rises too fast, it is necessary to check whether the air circulation motor is running normally. If the temperature is too high, you need to set the PID setting parameters. When the temperature rises directly over temperature protection, if the controller fails, it needs to replace the control instrument or solid relay.
2. When the temperature of the constant temperature and humidity test chamber reaches the test index
At this time, it is necessary to observe that the temperature change is a very slow temperature drop, or the temperature has a tendency to rise after the temperature reaches a certain value. The former should check whether the studio is dried before the low temperature test, so that the studio is kept dry. Then, put the sample into the working room for testing. If the sample in the working room is placed too much, the wind in the working room cannot be fully circulated. After eliminating the above reasons, it is necessary to consider whether the refrigeration system is faulty. In this case, it is necessary to produce. Manufacturer's professional staff for repairs.
3. The constant temperature and humidity test chamber equipment suddenly fails during work.
If there is a corresponding fault prompt on the control meter and there is an audible alarm. The user can quickly check which type of fault belongs to in the troubleshooting chapter according to the operation of the equipment. Therefore, professional maintenance personnel should perform troubleshooting to ensure that the test is carried out normally. Other environmental testing equipment will have other conditions in use, and it needs to be solved according to the status quo.
The above are several common faults and solutions for the constant temperature and humidity test chamber introduced by Xiaobian. If there are any problems not mentioned in this article, please consult Weibang Instrument and Equipment Company technical personnel.
