Abstract

PURPOSE: To improve the efficiency of a centrifugal fan, by reducing the amount of air flowing in the suction port of the fan.
CONSTITUTION: A seal packing 14 is attached to the suction port of a fan casing 12, its end being in touch with the inner ends of a side plate 16 of the fan 8. At the time of running-in the fan, the seal packing 14 pressed toward the side plate 16 is burned due to the friction heat to eliminate the clearance between them. This can eliminate air flowing in the suction port of the centrifugal fan, thus improving its efficiency.
