High-low temperature damp heat test box common troubleshooting 1. In the high temperature test, if the temperature change does not reach the test temperature value, the electrical system can be checked and the faults can be eliminated one by one. If the temperature rises very slowly, it is necessary to look at the air circulation system and see if the adjustment baffle of the air circulation is normally open. Conversely, check whether the motor operation of the air circulation is normal. If the temperature overshoots badly, then you need to set the PID setting parameters. If the temperature rises directly, over-temperature protection, then the controller fails and the control instrument must be replaced. 2. If the low temperature does not reach the test target, then you must observe the temperature change, whether the temperature drop is very slow, or whether the temperature will rise after the temperature reaches a certain value. The former must check whether it will be before the low temperature test. After drying in the studio, the test chamber is kept dry, and then the test sample is placed in the work chamber. The test sample is placed in the work chamber. The test sample in the work chamber is placed too much, so that the air in the work chamber cannot be sufficiently circulated. After eliminating the above reasons, It is necessary to consider whether it is a fault in the refrigeration system. In this case, it is necessary to ask a manufacturer's professional to perform the repair. The latter phenomenon is caused by the poor use environment of the equipment. The ambient temperature of the equipment and the location of the equipment (the distance between the cabinet and the wall) must meet the requirements (in the operating instructions of the equipment). High and low temperature hot and humid test chamber 3. In the hot and humid test, the actual humidity will reach 100% or the actual humidity and the target humidity are very different, the value is much lower, the former phenomenon: may be caused by dry gauze on the wet ball sensor, then check the wet Whether there is water shortage in the ball sensor's water tank, the water level in the water tank is automatically controlled by a water level controller, check whether the water level controller water supply system is normal, and whether the water level controller is working properly. Another possibility is that the wet ball gauze may cause the gauze to become hard due to the long use time or the purity of the water supply, so that the gauze cannot absorb moisture and dry, and the above phenomenon can be eliminated only by replacing or cleaning the gauze. The latter phenomenon is mainly because the humidification system is not working. Check the water supply system of the humidification system. Check whether there is a certain amount of water in the water supply system. Control whether the water level of the humidifying boiler water level is normal and whether the water level in the humidifying boiler is normal. If all of the above is normal, then check the electrical control system, which requires professional maintenance personnel to perform the repair. 4. When the equipment suddenly fails during the test operation, a corresponding fault display prompt appears on the control instrument and there is a voice alarm. The operator can quickly check which type of fault belongs to in the troubleshooting chapter of the operation of the equipment, and then the professional can quickly eliminate the fault to ensure the normal operation of the test. Other environmental test equipment will have other phenomena in use, it must be specific phenomena, specific analysis and exclusion. The environmental testing equipment should also be regularly maintained. The condenser of the refrigeration system should be regularly cleaned. For the moving parts, lubrication should be done according to the instructions, and the electrical control system should be regularly maintained and inspected. These tasks are indispensable. Hong Chin boasts a research institute specializing in the research and development of environmental testing equipment. It has mature testing methods and laboratories for ring testing. It has gathered a group of outstanding talents and well-known experts in the industry. A strong R&D team leads the domestic test technology. Development direction.
