How to deal with the failure of the high and low temperature test chamber?

1. High and low temperature testing equipment In high-temperature testing, such as temperature changes when the test temperature value cannot be reached, the electrical system can be checked and the faults can be fixed one by one. If the temperature rises very slowly, check the airflow system to see if the airflow control panel is open normally, otherwise check if the airflow motor is working normally. If the temperature overshoot is , the PID adjustment parameters need to be adjusted. If the temperature rises directly, the over-temperature protection means that the controller is defective and the control instrument needs to be replaced. uUWTextile Testing Instruments, Testing Equipment Manufacturer

Second, high and low temperature test equipment in the process of trial operation TritIf an error suddenly occurs in the control panel, the corresponding error message appears on the control instrument and an acoustic alarm sounds. The operator can quickly check what kind of error it belongs to in the troubleshooting chapter of the operation and use of the device, and then ask professionals to quickly troubleshoot to ensure the normal progress of the test. There will be other phenomena when using other environmental testing equipment, so it is necessary to analyze and eliminate specific phenomena. The environmental test equipment should be serviced regularly, the cooling system condenser should be cleaned regularly, the moving parts should be lubricated according to instructions and the electrical control system should be regularly serviced and checked - these tasks are essential. uUWTextile Testing Instruments, Testing Equipment Manufacturer

Third, the low temperature of the high and low temperature testgdevices cannot reach the test. Then you need to observe the temperature change, whether the temperature decreases very slowly or the temperature tends to increase after the temperature reaches a certain value. The former must check whether the studio is dried before the low temperature test, so that the work After the room is kept dry, put the test sample in the work room, and then do the test Whether the test samples are placed in the work room too much, so that the Wind in the working area cannot be completely circulated. In the event of a fault, the manufacturer's specialist staff must be commissioned with the overhaul. The latter phenomenon is caused by the poor operating environment of the device. The ambient temperature and the location of the device (the distance between the back of the case and the wall) must meet the requirements (this is specified in the device user manual). uUWTextile Testing Instruments, Testing Equipment Manufacturer

4. During the high and low temperature chamber humid heat test, the actual humidity reaches 100%, or the actual humidity is greatly different from the target humidity and the Value is much the former phenomenon: maybe if the gauze on the wet bulb sensor is dry, then check whether there is no water in the wet bulb sensor tank. The water level in the tank is automatically controlled by a water level controller. Check whether the water supply system of the water level controller is normal. Whether the work is normal. Another possibility is that due to long-term use or the purity of the water supply, the wet ball gauze hardens the gauze, causing the gauze can not absorb water and dry. As long as the gauze is replaced or cleaned, the above phenomenon may occur be eliminated The latter phenomenon is mainly that the humidification system is not functioned, check the water supply system of the humidifying system, whether there is a certain amount of water in the water supply system, whether the water level control to control the water level of the humidifying boiler is normal, and whether the water level in the humidifying boiler is normal Check the electrical control system, and ask professional maintenance personnel to check it overtake.uUWTextile Testing Instruments, Testing Equipment Manufacturer
