Rotor balancing service site - PRE -7060

Service Dynamic balancing rotors "in situ" technique uses influence coefficients matrix to establish the relationship between the vibration of the rotor on its own supports and residual imbalance mass eccentricity over the center of rotation.

Balancing technique "in situ " is useful in open access rotors such as fans, rollers, spindles, rotors or in closed access clearing dishes pre - installed, as the case of vertical pumps, turbines, etc.

The main advantage of balance "in situ" is the cost savings in the removal, transport, and assembly bench execution large rotors or weights, or installed in inaccessible locations requiring cranes or other hazardous operations.

Implementing a balanced work according to the recommendation that includes ISO - 1940 provides the following advantages:

  • Decrease fatigue loading on the supports and increasing the useful life of the bushings and bearings.
  • Reduced vibration and noise that could affect the quality of the processed product.
  • Saving energy in the rotor drive less heating and electric motors.
  • Increased reliability of the equipment and process as well as of operational safety by preventing any release of rotor by the action of centrifugal force.
