Routine maintenance of high-vacuum bell-jar furnaces is crucial for ensuring their safety and stability, and improving production efficiency and product quality. Here are some key maintenance points:
Operating Procedures:
When opening the furnace door, pause briefly after the door leaves the furnace body end face, then raise the door at full speed to the appropriate height.
When opening the furnace, ensure the trolley is fully inside, then lower the door and start the control cabinet for heating.
When loading workpieces, ensure their dimensions are smaller than the furnace's effective dimensions to avoid overload.
During heating, strictly follow the process requirements to avoid operating the equipment at excessive temperatures.
Maintenance Procedures:
Regular Cleaning: Remove dust, dirt, and residue from the furnace to maintain heat conduction and uniformity.
Inspect and Maintain All Components: Including heating elements, control systems, and insulation layers, ensuring they are functioning properly.
Safety Checks: Ensure safety equipment and protective measures are functioning correctly, such as temperature protection devices, overload protection devices, and emergency shutdown devices.

Daily Usage Precautions:
Inspect all electrical systems and equipment before starting.
During operation, ensure there are no flammable materials around the furnace, and operators must not smoke.
When loading the furnace, strictly follow the process requirements to ensure a smooth protective atmosphere.
When heating, proceed slowly to avoid exceeding the safe temperature.
Daily Maintenance and Care:
Moisture and Vibration Prevention: Avoid exposing the high-temperature furnace to moisture or severe vibration.
Cleaning and Maintenance: Clean the equipment regularly, especially draining water from the water filter promptly.
Calibration: Calibrate the equipment regularly to ensure measurement accuracy.
By following these maintenance and operating procedures, you can ensure the normal operation of the high-vacuum bell jar furnace, extend its service life, and improve work efficiency and safety.
