Cited the fan's role as an important draft fan mechanical ventilation, environmental protection in many industries, metallurgy, boilers, etc. play a huge role in the fire fan, you explain in detail below: 1, boiler flue gas extraction centrifugal induced draft fan, either power plant boiler, or a variety of industrial boilers, coal-fired, oil-fired boiler, the flue gas is required for the induced draft fan leads. 2, furnace flue gas heat recovery and lead to three, the wind dust 4, 5 workshops exhaust emissions, chemical gas transportation reasons for the increased vibration induced draft fan and induced draft fan solution is what the cause of vibration increases, in general, the main There are the following: (1) the material used in the fan rotating parts uneven fan, or an error has occurred in the manufacturing process, so that the rotor mass imbalance. (2) fan installation, maintenance quality, but off. (3) rotor wear and tear, or the rotor is damaged, or is the front and rear guide vanes for wear, deformation. (4) The opening of the import and export of the baffle adjustment is not in place, or a bearing and housing and other faulty. (5) maintenance technology, however, or under high load condition, the vibration increases. In addition to these reasons, in addition there is the high-load or full load, or is unstable vibration induced draft fan maintenance, which appeared in the periodical vibration. For these reasons, the measures we can take are: the disintegration of the fan first, and then on the parts checked for damage, if damaged the need for replacement. Connection bolts and anchor bolts accordingly check if loose should be tightened.
