How to maintain a vacuum sintering furnace on a daily basis?

The daily maintenance of vacuum sintering furnace is an important part to ensure its normal operation and extend its service life. Here are some key maintenance measures:
1. Cleaning and maintenance
Furnace cleaning:
The furnace body, instruments, and control cabinets should be kept clean and cleaned daily to prevent the accumulation of dust and debris.
The paint on the surface of the furnace shell should be kept intact, and any damage should be repaired in a timely manner.
Clean the dust inside the furnace with a silk cloth soaked in ethanol or gasoline, and ensure it is dry to prevent moisture from entering.
Heating element maintenance:
Regularly keep all parts of the vacuum sintering furnace clean to prevent dust and debris from falling onto the heating element or blocking the air holes on the surface of the heating element.
Regularly check the working condition of heating elements, including whether the terminals are tightened, tighten them in a timely manner, and replace aging or damaged heating elements.
2. Vacuum system maintenance
Vacuum degree maintenance:
When the vacuum sintering furnace is stopped, the vacuum state inside the furnace should be maintained at a certain level (such as below 6.65 × 10 ⁴ pa) to reduce air erosion of the equipment.
Vacuum pump maintenance:
Regularly inspect and replace the seals and pipelines of vacuum pumps and other vacuum equipment to ensure the stability and maintenance of vacuum degree.
Clean the pump body, replace the pump oil, and maintain the good working condition of the vacuum pump.
3. Lubrication and fastening
Lubrication and maintenance:
Maintain good lubrication of all components of the vacuum sintering furnace, and add lubricating oil (grease) if necessary, especially for the transmission mechanism.
Tightening inspection:
Regularly inspect and tighten the connecting bolts and various components to ensure reliable sealing and no air leakage.
Check if the wiring terminals of electrical equipment are securely fastened to prevent looseness and poor contact.
4. Temperature and control system maintenance
Temperature control:
Regularly inspect and replace temperature sensors and controllers inside the furnace to ensure the accuracy and stability of temperature control.
Calibrate the indicated values of the temperature and pressure flowmeter to ensure accurate measurement.
5. Other precautions
Safe operation:
Follow the operating procedures to avoid equipment damage or accidents caused by improper operation or use.
It is prohibited to bring workpieces containing corrosive substances and moisture into the furnace for heating to prevent damage to the equipment.
Regular inspection and recording:
Regularly observe the operation of the motor, changes in motor current, and temperature of motor bearings.
Regularly check the water outlet of the cooling water pipe to ensure the normal operation of the cooling system.
Carefully fill in various records, including shift handover records and technical indicator statistical reports, in order to promptly identify and solve problems.
Accessory maintenance:
Accessories such as vacuum pumps, valves, measuring instruments, thermal instruments, and electrical components should be used, repaired, and maintained strictly in accordance with the instructions.
In summary, the daily maintenance of vacuum sintering furnaces involves multiple aspects such as cleaning and maintenance, vacuum system maintenance, lubrication and fastening, temperature and control system maintenance, and other precautions. Through meticulous maintenance work, the performance stability of the vacuum sintering furnace can be ensured, its service life can be extended, and strong guarantees can be provided for production.
