What is Dynamic Balancing?

Dynamic balancing definition: “Dynamic balancing is a way of balancing machines by rotating parts quickly and measuring the imbalance using electronic equipment. The imbalance measured can then be corrected by adding or subtracting weight from the rotating parts until the vibration is reduced.”

Basically, all machines have some form of residual vibration. Enormous vibration in rotating machinery can cause high levels of noise and more importantly, significantly reduce the life of components. So, the ideal thing to do would be to remove all causes of vibration and allow the machine to run completely smooth. The process of balancing is the removal or addition of weight to the device, so that this effective mass center approaches the true axis.

REASONS YOU MIGHT REQUIRE DYNAMIC BALANCING

• To remove dirt build-up
• Impeller erosion
• Internal part corrosion
• Casting imperfections, voids and inclusions
• Mismatched lengths of keys and keyways
• Thermal and mechanical distortion
• Shifting mass due to loose parts or poorly tapered hub fits
• Previous balancing attempts have been unsuccessful
• Parts haven’t been assembled properly

BENEFITS OF COMPONENT BALANCING

• Noise reduction
• Vibration reduction/elimination
• Increased performance
• Extended motor life
