Abstract
The utility model discloses a stationary blade adjustable axle flow fan for a machine set of a 300 MV power station. The utility model is provided with a main shaft which is arranged in an inner tube in the center, wherein the main shaft is connected with a blade wheel. A rear guide vane is arranged behind the blade wheel, and a front guide vane connected with an approach cone and a housing is arranged in the front of the blade wheel. The front guide vane is in an angle adjustable shape, and the approach cone is connected with the inner tube in the center. An inlet box is arranged on the front end of the front guide vane, and a diffuser is arranged behind the rear guide vane. The utility model has the advantages of reasonable structure, high efficiency, wide range, reliable product operation and good safety; the fan efficiency can reach 87%; the utility model can adapt to the change of operating conditions of the machine set by adjusting the angle of the stationary blade (front guide vane).
