Centrifugal blower fan power can generally be divided effective power within the power and fan shaft power. Effective power, also known as total pressure effective power, it refers to the fan centrifugal fan Inner conveying gas, effective energy obtained from the fans in the unit time; inner power is the actual consumption of the gas turbine power; shaft power. Refers to the fan input power, which is equal to the inner fan power and mechanical power transmission losses sum. If the centrifugal fan has humped characteristics, then when it is in operation, when the load reduction Inner centrifugal fan pictures, 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 fan, it must be resolved. Under normal circumstances, at any speed, Inner Mongolia large centrifugal fan, as long as the good control of the flow of the fan so that it is greater than the limit of the fan flow parameters Inner centrifugal 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, bearing temperature is exceeded, etc., there is a run 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.
