Excuse me, what causes the vibration of lubricating oil filter screen in Chengdu shaft induced draft fan oil station?

Dust accumulated in the hub of induced draft fan falls off. The vibration source of the induced draft fan comes from the fan itself, and the main reason for the vibration of the lubricating oil filter screen of the Chengdu shaft induced draft fan oil station is the dust accumulation and falling off inside the induced draft fan hub. Induced draft fan is a kind of equipment that generates negative pressure through the rotation of impeller and then draws air from the system (equipment). It is installed at the tail of the boiler and used to extract the hot flue gas in the furnace.
