Active Balancing HydroBalancer HB 6000 Advantages Increase in product quality and machine availability Permanent vibration monitoring Integration of ring container into spindle Software for manual pre-balancing Applications Automatic balancing of Grinding Wheels Balancing during operation Compensation of unbalance in one or two balancing planes Achieving perfect smooth running Monitoring of unbalance vibrations Description The active balancing system HB 6000 compensates rotor unbalance using the component method. A four chamber ring container constitutes the balancing head. The unbalance compensation is achieved by controlled injection of liquid into the container chambers. Any correction size and direction can be generated within the limitations of the capacity as determined by the container design. Should the balancing capacity not be sufficient, a manual pre-balancing can be performed using the balancing software incorporated into the HB 6000 control unit. The fluid is injected into axial annular grooves of the container as it rotates. From there the fluid flows through an opening into the respective chambers of the container. A fixed nozzle block is positioned directly opposite the annular grooves. Solenoid valves release the fluid and insure that it is sent through a specific nozzle into the required annular groove and ring chamber. The chambers are emptied once the spindle stops rotating. A control unit constantly receives the measured data - rotational speed and vibrations. If the vibration exceeds a preset limit, an automatic balancing procedure is started by either the machine´s PLC or the user. The HB 6000 balances automatically in either one or two planes using an iterative procedure based on the actual measurement data. The ring containers are integrated into flanges or mounted as a separate part onto the rotor axis. The containers’ balancing capacity depends on size. The speed sensor is integrated in the nozzle block or mounted externally. Balancing liquids are either available directly on the machine (i.e. grinding oils or emulsions) or they are provided in open or closed circuits.
