Why can't the test chamber door be opened easily during the use of the thermal shock test chamber?

 

The thermal shock test chamber is a test chamber for simulating the environment. During use, there may be various extreme environments in the test chamber, such as special conditions such as extremely low temperature, high temperature and high pressure, high temperature and high humidity.

 

1. If the test chamber is undergoing an extremely low temperature test of -70 °C, this time the test chamber door is opened. First, the cold air flow will overflow the test chamber. If our fingers do not make any protection, touch the wall sample of the test box. Instant frostbite, the muscle tissue of the frostbite will even be necrotic. In addition, opening the test chamber door at extremely low temperatures may cause frosting of the evaporator, which may affect the cooling rate and may even cause damage to the compressor.

 

2. If the test chamber door is opened when the high temperature 150 °C test is being carried out in the test chamber, the high temperature gas will instantaneously rush out of the test chamber. If the relevant protection is not done, it is likely to burn our face if there is a burning point next to the test box. Low flammable materials may even cause a fire.

 

3. If it is other environmental testing equipment, such as constant temperature and humidity test chamber, the pressure and steam in the instrument will be very large when the high temperature and high humidity test box is used. If the test box door is opened at this time, there will be high temperature and high humidity. The steam rushes out of the test chamber and is also highly likely to cause severe burns to the operator.

 

Therefore, in the middle of the operation of the thermal shock test chamber, if it is not necessary to open the test box door, do not open the test line door; if it is necessary to open the test box door in the middle, please be sure to take relevant protective measures and use the correct Method Open the test chamber door.
