Working principle of high and low temperature impact test box (1)
We have mentioned the application of the high and low temperature impact test box. Below we introduce the working principle of the high and low temperature impact test box. The high and low temperature impact test chamber generates a high temperature environment (70 ℃ -125 ℃) and a low temperature environment (-25 ℃ --70 ℃) through the heating system and the refrigeration system of the unit, according to the relevant requirements of the temperature impact test.
Put the tested component into the load-carrying basket of the designated greenhouse, and when the two greenhouses reach the preset temperature and stabilize, "pull the load-carrying basket through the transmission mechanism to realize the movement of the tested component in the basket between the high and low greenhouses. The greenhouses are connected, and the components under test also enter another greenhouse from a high or low temperature state, so a lot of cooling and heating loads will be brought in. The unit should quickly return to the predetermined temperature of each greenhouse through the refrigeration system or the heating system.
When the temperature of the greenhouse where the tested component is kept stable for a long time, then the gear basket is reversed by the transmission mechanism to "take the tested component back to the original greenhouse, and it must also be quickly restored to the predetermined temperature. When the temperature is stable again for a long time, Repeat the above operation again to complete multiple temperature cycle impact tests.
