Some common faults and troubleshooting vacuum atmosphere furnace:

Some common faults and troubleshooting vacuum atmosphere furnace:
1. In the high-temperature tests, such as temperature changes reach the test temperature, you can check the electrical system, one by one troubleshooting. As the temperature rises very slowly, it is necessary to view the air circulation system, look at the wind circulation damper is open normally, otherwise, the motor is running check the air circulation is normal. If the temperature overshoot badly then you need to set the parameters tuning PID. If the temperature rise directly, over temperature protection, then the controller fails, replace the control instrument.
2. Equipment sudden failure during the test operation, the control corresponding fault appears on the instrument display and a voice prompt alarm. The operator can control the operation of equipment used in the troubleshooting chapter quickly check out which type fault, you can ask professionals quickly troubleshoot to ensure the normal tests. Other environmental testing equipment in use, there will be other phenomena, it should be specific phenomenon, detailed analysis and troubleshooting.
3. The low temperature reach indicator test, then you have to observe the change in temperature, the temperature drop is very slow, or the temperature to a certain value temperature tends to increase, the former must check, vacuum atmosphere furnace to make low temperature test Whether the studio before drying, the studio kept dry before the test sample into the studio to do the test, the test sample too much work if placed indoors, so that indoor air can not fully cycle, the exclusion of the above reasons After, we must consider whether the refrigeration system broke down, so we must ask the manufacturer for repair professionals.
