What are some common faults and troubleshooting methods of atmosphere furnace? We together look:
1. In the high temperature test of the atmosphere furnace, if the temperature change does not reach the test temperature value, you can check the electrical system and troubleshoot one by one. If the temperature rises very slowly, check the air circulation system to see if the adjustment baffle of the air circulation is open normally, otherwise, check if the motor of the air circulation is operating normally. If the temperature overshoot is severe, then you need to tune the PID setting parameters. If the temperature rises directly, some common over-temperature protection of the atmosphere furnace, then, the controller fails, and the control instrument must be replaced.
2. When the equipment suddenly fails during the test operation, the corresponding failure display prompt and audible alarm prompt will appear on the control instrument. The operator can quickly check which type of fault belongs to in the chapter of troubleshooting during the operation of the equipment, and then ask professionals to quickly troubleshoot the fault to ensure the normal progress of the test. There will be other phenomena in the use of other environmental test equipment, so specific phenomena should be analyzed and eliminated. Then you have to observe the temperature change, whether the temperature drops slowly, or the temperature has a tendency to rise after the temperature reaches a certain value, the former should be checked, whether the studio is dried before the low temperature test in the vacuum atmosphere furnace to make it work After the chamber is kept dry, put the test sample in the working chamber and do the test again. Whether the test sample in the working chamber is placed too much, so that the wind in the working chamber cannot be fully circulated. After the above reasons are eliminated, it is necessary to consider whether it is in the refrigeration system. The failure, failure and troubleshooting: In this way, please ask the manufacturer's professional for inspection and repair.
