PURPOSE:To correct dynamic unbalance of a cylindrical impeller for a blower with good work efficiency and safety. CONSTITUTION:According to the detection signal of a dynamic unbalance tester 25, thermoplastic synthetic resin liquid 10 in which dead-weight powder is mixed is supplied to necessary portions in plural blades of a cylindrical impeller 7 where dead-weights are required and the portions are solidified. Accordingly, the blades 2 where to install dead-weight, the dead-weight fitting portions of the blades 2 and the fitting weight are detected by the dynamic unbalance tester 25, and according to the detection signals, the synthetic resin liquid 10 where the dead-weight powder is mixed is automatically supplied, and the dead- weight can be fixed to the blades 2 by solidifying the synthetic resin liquid 10. |
