The two-box temperature impact test chamber is divided into a high greenhouse and a low greenhouse. The box structure design adopts a unique heat-dissipation structure and a heat storage and cold storage effect. The test object is completely static during the test, and the cold and hot air flow switching mode will be cold. The hot temperature is introduced into the test zone to achieve the purpose of the thermal shock test. During the test, we may encounter that the test basket does not work. What is the reason for this phenomenon?
1. The temperature impact test box is blue card dead, open the test box door, and visually check whether the basket is stuck;
2, the pneumatic solenoid valve is damaged, the cylinder gas path can not be switched, the basket can only stay at the starting position, the cylinder is not sealed inside;
3. The external power supply is not supplied with gas or the pressure regulating valve is damaged;
4. The wire rope is loose or broken.
The two-box temperature impact test chamber meets the standard:
GB/T2423.1-2008 Environmental testing of electric and electronic products - Part 2: Test methods Test A: Low temperature
GB/T2423.2-2008 Environmental testing of electrical and electronic products - Part 2: Test methods Test B: High temperature
