The hub of the impeller balancing drum and structure of type 1970 -81centrifugal blower, centrifugal blower performance, balance drum and the damage of sealing clearance were introduced. From design, material, process, operation, vibration, impeller hub locking damage causes were analyzed. Through the guarantee of the bearing seat and the diaphragm concentricity, according to experimental determination ZLlO4expansion coefficient, the balance of the drum and impeller sealing clearance was readjusted to prolong the
