The high temperature vacuum atmosphere furnace has the advantages of small temperature variation, energy saving and environmental protection, and easy to operate. Is a very good experimental furnace, for thermal processing, industrial workpiece processing, cement, building materials industry, pharmaceutical industry, analytical chemical industry, coal analysis for small workpiece thermal processing or treatment.
In general, there are many leakage faults in high temperature vacuum atmosphere furnace in spring and autumn. This time have to vacuum leak detection, vacuum leak detection is generally take a monthly rate of pressure rise (at room temperature, close all valves, stop the vacuum system running, read a number after 1 omin, read a number again after 1 h, the difference between the two Numbers is the value of pressure rise rate), to grasp equipment leakage trends, such as vacuum equipment downtime for a week in a row, to idle running (oven) at a time.
In this process, it is very important to have a set of good maintenance methods for the high-temperature vacuum atmosphere furnace. The following is the maintenance plan for the high-temperature vacuum atmosphere furnace introduced by the high-temperature vacuum atmosphere furnace manufacturer.
1. In the high-temperature experiment, if the temperature change fails to reach the experimental temperature value, the vacuum atmosphere furnace can check the electrical system and clean up the problems one by one. If the temperature rises slowly, it is necessary to check the wind circulation system to see whether the conditioning baffle of the wind circulation is open to the normal; otherwise, it is necessary to check whether the motor operation of the wind circulation is normal. If the temperature overshoot then need to adjust the PID setting parameters. If the temperature rises directly and overheat is maintained, then the controller is out of order and the control surface must be replaced.
2. The high temperature vacuum atmosphere furnace temperature to reach the goal, then you will investigate the change of temperature, temperature drop is so slow, is still the temperature to the temperature has a tendency to rise, after must value the former will check, vacuum furnace atmosphere is low temperature before the trial will be homework chamber drying, holds operation room to dry will again after the experiment to do experiment on samples in the homework assignments indoor experimental samples are placed too much, make homework indoor wind cannot be energetic cycle, after removing the cause, will think is it is the wrong with the refrigeration system, so please send professional personnel for repair.
3. When the high-temperature vacuum atmosphere furnace equipment still presents faults during the experimental operation, the control surface presents corresponding fault indication and an audible alarm. The operator can quickly check which kind of fault is attributed to in the chapter of fault cleaning in the operation and application of the equipment, and then the professional can quickly clean the fault to ensure the normal conduct of the experiment. Other environmental experimental equipment in the use of other representations, it is necessary to detailed representation, detailed analysis and cleaning.
