Some common faults and troubleshooting of high temperature vacuum atmosphere furnace:
1. In the high temperature test, if the temperature change does not reach the test temperature value
1. Check the electrical system and troubleshoot one by one.
2. If the temperature rises slowly, it is necessary to check the wind circulation system to see whether the regulating baffle of the wind circulation is open normally, and conversely, check whether the motor of the wind circulation is running normally.
3. If the temperature is too hot, the setting parameters of PID need to be adjusted. If the temperature rises directly and the overtemperature is protected, then the controller fails and the control instrument must be replaced.
2. The equipment suddenly breaks down during the test operation
1. Corresponding fault display prompt and audible alarm prompt appear on the control instrument.
2. The operator can quickly check which type of fault belongs to in the troubleshooting chapter of the operation and use of the equipment, and then ask professionals to quickly troubleshoot the fault to ensure the normal operation of the test.
3. There will be other phenomena in the use of other environmental test equipment, so specific phenomena should be analyzed and excluded.
3. the low temperature can not reach the test index
1. To observe the change of temperature, it is necessary to check whether the temperature drops slowly or rises after the temperature reaches a certain value.
2. Whether to dry the workshop before the low temperature test of the high temperature vacuum atmosphere furnace and keep the workshop dry before putting the test sample into the laboratory for the test.
3. Whether the test samples in the laboratory are placed too much, so that the wind in the laboratory cannot circulate fully, after the above reasons are eliminated, it is necessary to consider whether there is a fault in the refrigeration system, so it is necessary to ask the manufacturer's professional personnel for maintenance.
