Common fault solution of vacuum atmosphere furnace

Vacuum atmosphere furnace is a new heat treatment technology combining vacuum technology and heat treatment technology. The vacuum environment of vacuum heat treatment refers to the atmosphere environment under one atmosphere pressure, including low vacuum, medium vacuum, high vacuum and ultra-high vacuum. In fact, vacuum heat treatment also belongs to atmosphere controlled heat treatment. Vacuum heat treatment refers to all and part of the heat treatment process in the vacuum state. Vacuum heat treatment can realize almost all the heat treatment processes involved in conventional heat treatment, but the quality of heat treatment is greatly improved. Compared with conventional heat treatment, vacuum heat treatment can achieve no oxidation, no decarburization, no carburization, can remove the surface of the workpiece phosphorus debris, and degrease degidation, so as to achieve the surface of bright purification effect.

Some common faults and troubleshooting of vacuum atmosphere furnace:

1. In case of sudden failure of the equipment during test operation, corresponding fault display prompt and audible alarm prompt will appear on the control instrument. The operator can quickly check which kind of fault belongs to in the troubleshooting chapter in the operation and use of the equipment, and then ask the professional to quickly troubleshoot the fault to ensure the normal conduct of the test. Other environmental test equipment in the use of other phenomena, it is necessary to specific phenomenon, specific analysis and exclusion.

2. In the high temperature test, if the temperature change does not reach the test temperature value, the electrical system can be checked and faults can be eliminated one by one. If the temperature rises slowly, it is necessary to check the wind circulation system to see whether the regulating baffle of the wind circulation is open normally, and conversely to check whether the motor of the wind circulation is running normally. If the temperature overshoot is severe then the PID setting parameters need to be adjusted. If the temperature rises directly and the overtemperature is protected, then the controller fails and the control instrument must be replaced.

3, low temperature reach test indicators, then you have to observe the change of temperature, the temperature drop is slow, or temperature has a tendency to pick up after the temperature to a certain value, the former shall check and vacuum furnace atmosphere do low temperature test whether the studio before drying, to keep the studio after drying and then test samples into the studio to do test, indoor test sample is placed too much work, make work indoor wind is not fully cycle, after excluding the reasons, and consider whether in the refrigerating system failure.
