The daily maintenance of vacuum sintering muffle furnace is crucial for the stability of equipment performance, service life, and accuracy of experimental results. The following are some key points of daily maintenance:
Vacuum system maintenance
Vacuum pump maintenance: Regularly check the oil level of the vacuum pump. If the oil level is too low, add the required vacuum pump oil in a timely manner. Generally, the vacuum pump oil needs to be replaced every 500-1000 hours of operation to ensure its good pumping performance and lubrication effect. At the same time, regularly clean the filter of the vacuum pump to prevent dust and impurities from entering the pump body and affecting the normal operation of the vacuum pump.
Vacuum sealing inspection: Before and after each use, check the sealing condition of furnace doors, pipeline interfaces, observation windows, and other parts. If there is a loose seal, replace the sealing gasket or perform sealing treatment in a timely manner to ensure the sealing of the vacuum system and prevent air leakage from affecting the sintering effect.
Heating system maintenance
Heating element inspection: Regularly check the status of heating elements (such as heating wires). If any signs of breakage, deformation, or aging are found in the heating wires, they should be replaced in a timely manner. At the same time, keep the surface of the heating element clean to avoid the accumulation of dust and impurities, which may affect the heating efficiency and uniformity.
Temperature control system maintenance: The temperature sensor should be calibrated regularly to ensure the accuracy of temperature measurement. Prevent the temperature controller from being affected by vibration, moisture, etc., and maintain a stable working environment. In addition, do not arbitrarily change the parameters of the temperature controller to avoid affecting the normal operation of the equipment.
Furnace body cleaning
Internal cleaning: After each sintering is completed, wait for the furnace body to cool to room temperature and promptly clean the debris and dust inside the furnace. You can use a clean brush or vacuum cleaner for cleaning, but be careful not to damage the components inside the furnace. For stubborn stains, a suitable cleaning agent can be used for wiping, but it is important to ensure that the cleaning agent does not corrode the furnace material.
External cleaning: Regularly wipe the exterior of the furnace body to keep its surface clean and tidy. Avoid placing debris on the furnace body to avoid affecting heat dissipation and operation. If there are stains or oil stains, they can be wiped clean with a damp cloth.
Electrical system maintenance
Line inspection: Regularly check whether the power and control lines of the equipment are damaged, aged, or loose. If found, the circuit should be replaced or repaired in a timely manner to ensure good electrical connection and prevent safety accidents such as leakage and short circuit.
Grounding inspection: Ensure that the equipment is well grounded, regularly check whether the grounding circuit is firmly connected, and whether the grounding resistance meets the requirements. Good grounding is an important measure to ensure the safe operation of equipment and the safety of operators.
Other maintenance matters
Regular calibration: Regularly calibrate the vacuum degree, temperature and other parameters of the vacuum sintering muffle furnace to ensure that all performance indicators of the equipment meet the requirements. Reasonable calibration cycles can be established based on the frequency and importance of device usage.
Idle maintenance: If the equipment is not used for a long time, the oil in the vacuum pump should be drained and cleaned. At the same time, clean the interior of the furnace, keep it dry, and prevent moisture and rust. It is possible to preheat the equipment by powering it on at regular intervals to remove any potential moisture and extend its lifespan.
