Large centrifugal fan parking (1) Normal Parking: Parking normal fan, its operation is: first off its heat source, then the fan speed to a minimum and let the slow turn 2015 Shanxi centrifugal fan until the temperature dropped to normal temperature cabinet then stop the main motor. (2) Accident Parking: there are unforeseen circumstances that had unexpected stop, when the unit is in hot shutdown, give artificial disk drive until the cabinet temperature falls far below room temperature. If the centrifugal fan has humped characteristics, then when it is in operation, when the load reduction Shanxi centrifugal Blower and load flow drops to a certain level, then the fan work becomes unstable flow will become 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 this phenomenon occurs fan, then the fan is very unfavorable terms, would be damaging to the Shanxi fans centrifugal fan, it must be resolved. Under normal circumstances, at any speed, as long as the good control of the flow of the fan so that it is greater than the limit flow fan, centrifugal fan so will not appear on the phenomenon. Centrifugal fan maintenance, centrifugal fan is also very important in terms of its main contents are: (1) fan inspection will be carried out every two hours, if the fan is operating normally produced in Shanxi centrifugal fan, bearing temperature is exceeded, etc. There is the operating parameters, lubricants, etc., which are not negligible. Lubricants (2) use the fan, make sure there is a good quality, if deterioration should be promptly replaced.
