How to maintain the high and low temperature test chamber?

The dust and corrosive gas in the working environment of high and low temperature test chamber can also affect the flexibility of mechanical system, reduce the reliability of various limit switches, keys and photoelectric couplers, which is also one of the reasons for the corrosion of aluminum film of the necessary components. The high and low temperature test box machine / alternating damp heat test box produced by Dongguan Kejian instrument is used to simulate the natural high and low temperature change environment, which is widely used in the test of the adaptability of electronic, electrical products and other product parts and materials to the temperature environment in the process of storage and transportation, especially the changes of electrical and mechanical properties.

When maintaining the high and low temperature test chamber, the following points should be paid attention to:

1、 The management personnel must receive professional training before using, and be familiar with the performance of high and low temperature test box. The products of different manufacturers may be different. Therefore, when purchasing new high and low temperature constant humidity boxes, special personnel should be sent to the manufacturer for learning or the supplier should be invited to the factory for training.
2、 Put the high and low temperature test chamber in a relatively benign test environment, the best ambient temperature and humidity is: 5 ℃~ + 30 ℃≤ 85% R.H. for the laboratory without this condition, appropriate air conditioner or cooling tower must be equipped to ensure the compressor life and the overall test effect of the machine
3、 The dust prone parts of the high and low temperature test chamber should be cleaned regularly. For example, the circulating air blade and condenser fan will agglomerate a lot of dust and other small particles, which should be cleaned regularly.
4、 Keep the high and low temperature test chamber water channel smooth and the humidifier clean. If the water path is not smooth and the humidifier is scaling, it is easy to cause the humidifier to dry burn, which may damage the humidifier. Therefore, the water channel and humidifier must be cleaned regularly
5、 Clean the high and low temperature test chamber regularly to ensure its good ventilation and heat transfer performance. For the compressor with water cooling, it is necessary to ensure the water inlet pressure and inlet temperature, as well as the corresponding flow rate. Regularly clean and descale the condenser to obtain its continuous heat transfer performance
6、 If it is not used for a long time, the inner wall should be cleaned and kept dry. Power on the equipment once every half day for at least 1 hour.

7、 After the high and low temperature test box is used for a certain period, a certain amount of dust will accumulate inside. It is better to open the outer cover of the high and low temperature test box regularly to remove dust from the interior under the guidance of the maintenance engineer or under the guidance of the engineer. At the same time, the radiator of each heating element shall be re tightened, and the sealing window of the optical box shall be cleaned. If necessary, the mechanical part shall be cleaned And the necessary lubrication, finally, restore the original state, and then carry out some necessary testing, adjustment and recording.


The temperature and humidity of the high and low temperature test chamber are the important factors affecting the performance of the instrument, which can cause the corrosion of the mechanical parts, reduce the smoothness of the metal mirror, and cause the error or performance decline of the mechanical part of the high and low temperature test chamber. As a result, the aluminum film of optical components such as grating, reflector, focusing mirror, etc. of high and low temperature test chamber is corroded, resulting in insufficient light energy, stray light and noise, and even the instrument stops working, thus affecting the service life of high and low temperature test chamber.
