The temperature shock test chamber is suitable for military and aerospace units, and its maintenance difficulty is the highest among environmental testing equipment. According to the author's years of use experience, some common faults and troubleshooting methods of temperature shock test chamber are summarized. In the high temperature test of the temperature shock test box, if the temperature change does not reach the test temperature value, you can check the electrical system and eliminate the fault one by one. If the temperature rises very slowly, it is necessary to check the wind circulation system to see if the adjustment baffle of the wind circulation is opened normally. Low temperature can not reach the test index. Observe the temperature change, whether the temperature drops very slowly, or the temperature has a tendency to rise after the temperature reaches a certain value. After the chamber is kept dry, put the test sample into the working room before doing the test. Check whether the test sample in the working room is placed too much, so that the wind in the working room cannot be fully circulated. If it is not a similar situation, you can ask a professional manufacturer (Lin Pin) for repair. When the temperature shock test box is used in the damp heat test, the actual humidity will reach 10 or the actual humidity will be very different from the target humidity of 0%, and the value is much lower. It may be caused by the drying of the gauze on the wet ball sensor. Then check whether the water tank of the wet ball sensor is short of water. The water level in the water tank is automatically controlled by a water level controller. Check whether the water supply system of the water level controller is normal and whether the water level controller is working properly. You can change the wet ball gauze or try again with purified water. Or ask a professional electrician to overhaul the circuit control system. In addition to the correct operation of the operating procedures, the test personnel should also have an understanding of their structure. The cold and hot impact testing machine is composed of a cabinet, an air circulation system, a refrigeration system, a heating system and a humidity control system. In addition, the reason for the failure of the temperature shock test chamber may also be the poor ambient temperature. The manufacturer recommends that the optimal temperature is 5-28 degrees (the average temperature in 24 hours is around 24 degrees), and the humidity is about 95%. Any precision instrument can It is necessary to have a good place to ensure the best performance of the instrument. Ensure the service life of the product. This maintenance tip should be known to any laboratory manager or machine operator.
