Boiler fan bearing block moving is what happened?
Reasons for the movement of the bearing pedestal of the boiler draft fan:1, the blade of wind or corrosion, wind erosion, leading to fan out of dynamic balance.2, bearing damage.3, the wind shaft dynamic balance is not good.4, flue resonance.Exclude yourself.Flue resonance is usually a problem with the new furnace, and other problems occur over a period of time.- do not rule out the new air blower unqualified phenomenon.
The boiler fan bearing block may move for the following reasons:1, the bearing and bearing seat clearance is too large;2, bearings on the rotating shaft loose or rotating, that is, insufficient interference;3, the bearing clearance is too large.4, the blade of ash or corrosion, wind erosion, leading to fan out of dynamic balance.5, the wind shaft dynamic balance is not good.6, flue resonance.7, bearing damage.
When the bearing block of the boiler fan moves, first consider whether the connection between the bearing seat and the base (bracket) is loose, it should be tightened in time to ensure the smooth running of the fan. Then, analysis of the reasons for the loosening of bolts, basically can be considered as a fan vibration caused by the operation.The vibration of the blower is mainly destroyed by dynamic equilibrium. The reasons may be: 1. The accumulation of dust, oil, or partial corrosion and oxidation of the blade will cause the jump and imbalance in operation. 2, lack of lubrication or gap in the bearing. 3, the bearing steel ball damage, rupture, sick work. 4, the new fan of the above problems, you can consider the quality problems, flue resonance, and other factors.For possible reasons, gradually investigation, rest or replacement on it.
