If the centrifugal fan has humped characteristics, then when its price in Taiyuan centrifugal fan is running, when the load reduction Taiyuan custom centrifugal fan, and load flow drops to a certain level, then Taiyuan centrifugal fan specifications, then the fan will work becomes unstable, the 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 a surge. If this phenomenon occurs fan, then the fan is very unfavorable terms, would be damaging to the 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, the fan is running correctly Taiyuan centrifugal fan, bearing temperature is exceeded, but also in There is also 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. After centrifugal fan maintenance (1) running 2000 hours a. Remove surface dirt, bearings, bolts, inlet and outlet, couplings, belt, etc. to check for problems. b. for lubrication should be checked, lubricants and seals were replaced. (2) run 8000 hours, including the above, but also on the impeller shaft and inspect parts, any questions should be repaired, not replace.
