Many customers will discover some phenomena when using the high-low temperature rapid changing test chamber for the first time, and suspect that the quality of the machine itself is not good enough, and hurriedly contact the manufacturer to solve the problem. In fact, when using the high-low temperature rapid changing test chamber for the first time, if these phenomena occur at times, it is not a problem in the quality of the machine; but some minor normal phenomena, the editor will explain to you the reason:
1. When the high-low temperature rapid changing test chamber is used for the first time, there may be a particularly unpleasant smell, but this is not caused by a failure somewhere in the equipment, but the lubricating oil in the working room is heated. What is distributed will not affect the experiment. And with the use of time, this problem will gradually disappear.
2. In the first low temperature test of the high-low temperature rapid changing test chamber, the cooling rate may be relatively slow due to the initial circulation and operation of the low temperature system pipeline, and it will return to normal after multiple tests.
3. When the high-low temperature rapid changing test chamber is first tested for humidity and heat test, it appears that the actual humidity will reach 100% or the actual humidity will be quite different from the target humidity, and the value will be much lower. The former phenomenon: It may be caused by the dry gauze on the wet bulb sensor. Firstly, you should check whether the water tank of the wet bulb sensor is short of water. The water level in the tank is automatically controlled by a water level controller. Then find out whether the water supply system of the water level controller works normally and whether the water level controller works normally. Another possibility is that the wet ball gauze is too dry, or the purity of the water supplied is not suitable, which will make the gauze hard, so that the gauze cannot absorb water. To solve this problem, you just need to replace or clean the gauze to eliminate the above issues. The latter phenomenon is mainly that the humidification system does not work. Check the water supply system of the humidification system to find out 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. The above content is what we explained to you.
