Vacuum atmosphere furnace troubleshooting method

What are some common faults and troubleshooting methods of vacuum furnace? Let's get to know about it!


1. In the high temperature test, if the temperature change cannot 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, check the air circulation system to see if the regulating damper of the air circulation is opened normally. Otherwise, check whether the motor of the air circulation is running normally. If the temperature overshoot is severe, the PID setting parameters need to be set. If the temperature rises directly and the over temperature is protected, the control instrument must be replaced if the controller fails.


2. When the equipment suddenly fails during the test operation, the corresponding fault display prompt and audible alarm prompt will appear on the control instrument. The operator can quickly check the type of fault according to the chapter of troubleshooting in the operation and use of the equipment, and then ask the professional to quickly remove the fault to ensure the normal test. There will be other phenomena in the use of other environmental test equipment, which should be analyzed and excluded specifically.


3. If the low temperature can not reach the test index, then you should observe the change of temperature, whether the temperature drops slowly, or whether the temperature has a rising trend after reaching a certain value. The former is to check whether the working room is dried before the low temperature test in the vacuum atmosphere furnace, and then put the test sample into the working room for further test after keeping the working room dry. Whether the test sample in the working room is Too many places make the air in the studio unable to circulate fully. After the above reasons are eliminated, it is necessary to consider whether it is a fault in the refrigeration system. In this way, it is necessary to ask the professional personnel of the manufacturer for maintenance.
