Tips for prolonging the life of cold and hot impact test chamber

Tips for prolonging the life of the cold and hot impact test chamber: the cold and hot impact test chamber is suitable for aerospace, automobile and other units It is also a difficult equipment in the environmental test equipment The following are some common faults of the cold and hot impact test chamber summarized When the cold and hot impact test chamber is conducting high temperature test, if the temperature change cannot reach the temperature value of the test, the electrical system can be checked and eliminated one by one On the contrary, if the temperature rises slowly, the air circulation system can be checked to see whether the regulating damper of the air circulation is normally opened If the index of low temperature test can observe the change of temperature, it is the slow temperature drop, not the trend of temperature rising after the temperature reaches a certain value Before the low temperature test, the working room must be dried to keep the working room dry and then put the test sample in the working room The samples in the working room cannot be put too much, which will cause the air in the working room to be unable to circulate In the damp heat test of the temperature impact test chamber, the drying of the gauze on the wet ball sensor will cause a great correlation between the actual humidity and the target humidity The test personnel should understand the structure of the test chamber and some operating rules Poor ambient temperature may also cause failure of the cold and hot shock test chamber It is suggested that the temperature should be 5-28 ℃, and the temperature should be about 95% The machine operator must know some maintenance tips to ensure the service life of the product.
