Vacuum Furnace Faults Solutions
Vacuum furnace in the use process will inevitably appear such and such problems, then when there are problems, how to solve them? Different problems have different solutions. Let's take a look at them.
1. In the high temperature test of vacuum furnace, if the temperature change can 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, we should check the wind circulation system to see whether the regulating baffle of the wind circulation is open properly, and vice versa, check whether the motor of the wind circulation is running properly. If the temperature is too high, the setting parameters of PID need to be adjusted. If the temperature rises directly and the overtemperature protection occurs, the control instrument must be replaced if the controller fails.
2. When the equipment suddenly breaks down during the test operation, the corresponding fault display prompt and audio alarm prompt appear on the control instrument. Operators can quickly check which kind of faults belong to in the chapter of troubleshooting in the operation and use of the control equipment, and then ask professionals to quickly troubleshoot the faults to ensure the normal operation of the test.
3. If the low temperature can not reach the test target, then you should observe the change of the temperature, whether the temperature drops very slowly or the temperature tends to rise after reaching a certain value. The former should check whether the vacuum atmosphere furnace dries the studio before doing the low temperature test, so that the studio keeps dry and then puts the test sample into the studio for further test, whether the test sample in the studio is or not. The excessive placement makes the air in the working room not fully circulate. After eliminating the above reasons, we should consider whether it is a fault in the refrigeration system.
