Oil air lubrication for high-temperature furnace roller conveyors: unaffected by heat and fire
Release time:
2025-05-19
The CKD220# gear oil used in the oil air lubrication system has a flash point of approximately 230℃—meaning the oil needs to be heated to 230℃ to potentially ignite. In actual operating conditions, bearings face a risk of burning when the external temperature reaches 110℃ and the internal temperature reaches 90℃, far below the oil's flash point.
More importantly, the working principle of oil-air lubrication is crucial. Using compressed air as a carrier, the airflow directly cools the bearing by 30-150℃ during lubrication. This effectively adds a cooling shield to the bearing and oil, keeping critical components within a safe temperature range.
Compared to traditional lubrication, oil-air lubrication offers additional advantages: it avoids the carbonization and coking problems caused by high temperatures. The lubricant is precisely delivered to the friction points as fine droplets, ensuring lubrication efficiency while preventing the hazards caused by grease buildup.
Therefore, in scenarios like high-temperature furnace roller conveyors, oil-air lubrication not only functions reliably but also eliminates the risk of fire at its source. Choosing the right lubrication method ensures safe operation even in high-temperature conditions.
