Centrifuge is driven by motor drive shaft rotating, make the centrifugal active wheel rotate, active wheel friction produced by touching with the mold running wheel driven the mold rotate. In the process of mold rotation, the concrete in the mold under the action of centrifugal force is uniformly distributed along the mold inwall, and close-grained, gradually through the low speed, middle low, medium, medium high, high-speed stage centrifugal molding, to make the concrete, steel effectively combine to form a reinforced concrete pole preliminary. Due to the working principle of centrifuge is through the mold with the center line of the itself as the axis of rotation of the centrifugal force to make concrete centrifugal molding, so the mold running wheel axis roundness and straightness for mold centrifugal molding is of great significance.
