Centrifugal fans surge phenomenon should be how to face? How to maintain it? If the centrifugal fan has humped characteristics, then when it is in operation, when the load is reduced, and the load flow drops to a certain value, then the work becomes unstable fan, flow becomes unstable , or is suddenly big suddenly small, so there will be "breathing" noise, while there will be a strong vibration, which is called the surge. If the fan phenomenon occurs, then the fan is very unfavorable terms Francis fan brand, would be damaging to the fan, it must be resolved. Under normal circumstances, at any speed, as long as control the flow of the fan to be larger than the limit flow fan, centrifugal fan then there would not be the phenomenon. Maintenance centrifugal fan, centrifugal fan is also very important in terms of its main contents are: (1) The fan inspection will be carried out every two hours, the fan is operating normally, the bearing temperature is exceeded, etc., there is a run parameters, lubricants, etc., which are not negligible. Lubricants (2) fan used, should ensure a good quality, once deterioration should be promptly replaced.

Induced draft fan vibration increases reasons, according to the analysis professionals in general are mainly the following for: Material (1) Fan rotating parts used in non-uniform, or an error has occurred in the manufacturing process, so that the rotor mass occurs imbalance. (2) The fan installation, maintenance quality, but off. (3) rotor wear and tear, or rotor damaged, or is the front and rear guide vanes for wear, deformation. (4) The opening of the import and export flap adjustment is not in place, or the bearings and bearing, etc. is faulty. (5) access technology, however, or under high load condition, vibration increases. In addition to these reasons, in addition there is the high-load or full load, vibration or instability, which appeared in periodic vibration. For these reasons, the measures we can take are: first, the disintegration of the fan DC fan brand, and then to the parts checked for damage, if damaged the need for replacement. Connection bolts and anchor bolts accordingly inspect proof fans brand, if loose should be tightened.
