Rotor balancing device for pneumatic coal dust conveyor

摘要

For balancing the hollow rotor for a blower for coal dust conveying equipment, a pressure medium is used for discharging balancing bodies (14) into the rotor. The rotor has two end rings supported each side of a circular carrier plate mounted on a hollow rotary shaft. The bodies are discharged from a storage vessel through a supply tube connected to storage pockets inside the rotor. Delivery of the bodies is controlled so that the working medium does not enter their supply lines and storage pockets. Connected to an extension (20) of the spindle driving the hollow shaft is a hollow supply spindle (27) with a channel (28) which bends outwards for connection to channels (3) incorporated in the wall of the extension. The extension channels form a rotary connection with delivery tubes inside the rotor, supplying the storage pockets.
