The utility model discloses a bilobed wheel for the centrifugal fan. Air variation scope is great in a lot of industry places, and the requirement is unsatisfied with to the range of flow of low discharge fan, large-traffic fan energy consumption when the amount of wind is less is great. The utility model discloses an out rotor and interior impeller, the rim plate of out rotor is fixed on the reel, multi-disc blade along circumference equipartition, and one side is all fixed on the outer edge of rim plate, and the opposite side is all fixed with the wheel cap, the rim plate of interior impeller is fixed on the reel, and one side of multi-disc blade is all fixed on the outer edge of rim plate, and the opposite side is all fixed with the wheel cap. The utility model discloses can open different impellers according to amount of wind requirement, improve the reasonable slew range and the stream pressure of ventilation blower, realize that centrifugal fan's a machine is multi-purpose, open inside and outside impeller simultaneously, the low-speed fluid of internal lobe wheel pair rim plate department does work, and the air speed that can effectively reduce blade entry, rim plate and wheel cap department is poor, makes the air speed of blade entrance more even to raise the efficiency the noise reduction.
