Some common faults and solutions of vacuum gas quenching furnace

When a sudden failure occurs in the vacuum gas quenching furnace during test operation, the corresponding fault display prompt and audible alarm prompt appear on the control instrument. The operator can quickly check which type of fault belongs to in the chapter "Troubleshooting during the operation and use of the equipment", and then invite professional personnel to quickly eliminate the fault to ensure the normal operation of the test. Other environmental test equipment may have other phenomena in use, which requires specific analysis and elimination.
"If the low temperature of the vacuum gas quenching furnace cannot meet the test index, then you should observe the temperature change, whether the temperature drops slowly or there is a tendency for the temperature to rise after reaching a certain value. For the former, it is necessary to check whether the working chamber is dried before performing the low temperature test in the vacuum atmosphere furnace, keep the working chamber dry, and then place the test sample in the working chamber before conducting the test. If there are too many test samples in the working chamber,", "If the air in the working room cannot be fully circulated, after eliminating the above reasons, it is necessary to consider whether there is a fault in the refrigeration system. In this way, it is necessary to ask the manufacturer's professional personnel for maintenance.".
During the high temperature test of the vacuum gas quenching furnace, 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 slowly, it is necessary to check the air circulation system to see if the regulating damper of the air circulation is opened normally. Otherwise, it is necessary to check whether the motor of the air circulation operates normally. If the temperature overshoot is severe, it is necessary to adjust the PID setting parameters. If the temperature rises directly and the temperature is protected against overheating, the controller fails and the control instrument must be replaced.
