Large centrifugal fan parking (1) Normal Parking: Parking normal fan, its operation is: first off its heat source, then the fan speed to minimize the high centrifugal fans, let the slow turn, until the cabinet temperature dropped to room temperature, then stop the main motor. (2) Accident Parking: there are unforeseen circumstances that had unexpected stop, when the unit is in hot shutdown saving centrifugal fan, give artificial disk drive until the cabinet temperature falls far below room temperature. If the impeller diameter is relatively large, that this centrifugal fan models large enough. So it will effectively enhance the power, which is a large reason why all power is relatively large in size than the fan. There is a degree of tilt centrifugal fan impeller, if the degree of inclination is small, then the power will be relatively small. Conversely, if a large degree of tilt, then centrifugal fan power will be larger. But this is also a centrifugal fan in a certain range, because after all, the degree of tilt of the impeller is no way to ninety degrees, at most, that is, an acute angle of within, should the otherwise efficient centrifugal fans, centrifugal fans this will be In the relatively short life of the impeller. So, if you want the same current, while increasing the efficiency of centrifugal fans, the only aspect of the fan from the impeller to make improvements.
