Chamber known as "natural environment test machine", which is mainly used for high-temperature raw material, low temperature resistance, and wet properties. Testing the quality of the appropriate electronics, cars, plastic products, metal materials use, the choices are all intelligent dashboard touch screen, you can set the program flow loop system experiments, experiments carried out in part, described the circulatory system chamber invalid because of the situation, below to carry out analyzes for invalid reasons:
1. Temperature Xunhuanjitong STRESS main parameters:
The main key parameter six: ① temperature limit; ② lower limit temperature; ③ temperature transition rate;
④ time limit temperature insulation; ⑤ time lower limit temperature insulation; ⑥ Xunhuanxitong frequency.
2. Temperature Characteristics Analysis Xunhuanxitong STRESS: Xunhuanxitong temperature experiment, the test chamber is a cyclone precision major critical parameters, primarily the temperature transition rate parameter harm goods. This provision when several experiments carried out experiments commodity addition, intermediate goods experiment, experiment, and environmental chamber wall intermediate goods required to have appropriate spacing, to facilitate the cyclone can freely experiment Xunhuanxitong in the middle of the middle of goods, commodities and experimental tank wall.
3. Temperature Xunhuanxitong principle be invalid and caused by stress sensitive element: temperature Xunhuanjitong make different coefficient of thermal expansion different Peng Zhang situation is not the same raw materials, leading to detachment, cracked, its sensitive components such as paints and other coating layer .
3.1 Xunhuanxitong temperature or the screw connection is not strong riveting connector loose, which sensitive element such as a screw, rivet member and the like;
3.2 Temperature Xunhuanxitong mechanical device supporting force enough slack press-fit connector; alternating high and low temperature environmental chamber test the material temperature difference Xunhuanjitong brazing or increase in contact resistance caused by the route guidance is sensitive components such as resistors and other components ;
3.3 Xunhuanjitong temperature and erosion of the contact points Huanjingwuran which alloy elements such as sensitive products.
The above description describes chamber invalid because of circulatory system, so that everybody will understand more professional knowledge test chamber. More clearly the actual operation of the application device.
