How to solve the problem of vacuum gas quenching furnace failure?

1. The low temperature of the vacuum gas quenching furnace can not reach the test index, then you have to observe the change of temperature, the temperature is very slow, or the temperature has a rising trend after the temperature reaches a certain value. The former should check the vacuum atmosphere. Whether the furnace is dried before the furnace is tested at low temperature, the studio is kept dry, and then the test sample is put into the working chamber and then tested. The test sample in the working chamber is placed too much, so that the wind in the working chamber cannot be fully circulated. After excluding the above reasons, it is necessary to consider whether it is a fault in the refrigeration system, so it is necessary to ask the professional of the manufacturer for maintenance.

2. In the high temperature test of the vacuum gas quenching furnace, if the temperature change does not reach the test temperature value, the electrical system can be inspected and the faults can be eliminated one by one. If the temperature rises very slowly, it is necessary to check the air circulation system to see if the regulating baffle of the wind cycle is normal. On the contrary, check whether the motor of the wind cycle is running normally. If the temperature is too high, you need to set the PID setting parameters. If the temperature rises directly and the temperature is over-protected, then the controller fails and the control instrument must be replaced.

3. When the vacuum gas quenching furnace suddenly fails during the test operation, the corresponding fault display prompt appears on the control meter and there is an audible alarm prompt. The operator can quickly check which type of fault belongs to the fault diagnosis chapter in the operation of the equipment, and then ask the professional to quickly eliminate the fault to ensure the normal operation of the test. Other environmental testing equipment will have other phenomena in use, and it will be specific phenomena, specific analysis and elimination.
