Self-examination method for difficult cooling and humidification in a constant temperature and humid

Wuhan Guoliang Instrument Co., Ltd. frequently receives technical advice calls from some customers. For example, the constant temperature and humidity test chamber cannot reach the set temperature and humidity values ​​in a short time. So, in such a situation, what are the reasons for this error? In order to solve such a problem, we cannot be in a hurry and disassemble the constant temperature and humidity box for inspection, so the problem cannot be solved continuously, and it also delays the time of the test. Today, technicians from Shanghai Qingji Instrument taught us how to self-check and fix the problem of difficult cooling and humidification in the constant temperature and humidity chamber?RTOTextile Testing Instruments, Testing Equipment Manufacturer


1: If the temperature in the test chamber does not drop for a long time, we need to analyze the temperature first. The temperature falls very slowly, or the temperature tends to rise afterthe temperature has dropped to a certain value. The temperature drops very slowly, so we need to check whether the working room is dry before the test, keep the working room dry, and then put the test samples in the working room to do the test again, whether there are too many test samples in the working room, so that the wind in the working area cannot be completely circulated. After eliminating the above reasons, it is necessary to check whether there is a fault in the refrigeration system. If the refrigeration system fails, you can contact the manufacturer directly whether it should be replaced or repaired.
2: When we do the humidification test, the humidity in the constant temperature and humidity test box is always lower than the value we set, and the humidity value in the test box is much lower than the value we set. We first check that there is no water in the wet bulb sensor tankWater level in the tank is automatically controlled by a water level controller. Check whether the water supply system of the water level controller is normal and whether the water level controller is working normally. If it is not normal, it must be repaired immediately. If it is not because of the above problems that there is no humidification, we must check whether the electric control can not work normally due to the long period of use. If the electrical control does not work properly and the humidification in the test chamber cannot be carried out, we must contact the manufacturer and ask professionals to come and fix it.

Have you learned the above two self-checking methods for the difficulty of cooling and humidifying in the constant temperature and humidity chamber? However, as the use of the constant temperature and humidity chamber increases, the above probLeme on understandable. Since the constant temperature and humidity test chamber also ages, we usually do a good job of maintaining the test chamber and try not to cause a headache at critical moments, which certainly not every customer wants to experience.
