The Main Differences Between Pulley Dynamic Balancing And Static Balancing Tests

 The main differences between pulley dynamic balancing and static balancing tests lie in the number of correction planes, applicable conditions, and balancing accuracy.

 Number of correction planes: static balancing has only one correction plane, while dynamic balancing has two correction planes.

 Applicable conditions: when the rotor outer diameter D and length L satisfy D/L≥5, only static balancing is required regardless of its operating speed; when L≥D and the operating speed is greater than 1000 r/min, dynamic balancing is required. However, these are only general principles, and rotors with special requirements must be considered separately.

 Balancing accuracy: the accuracy of dynamic balancing is higher than that of static balancing. In other words, if static balancing passes, dynamic balancing may not necessarily pass; but if dynamic balancing passes, static balancing will definitely pass.

 In addition, practical application should also take into account factors such as the workpiece's use and rotational speed.

 Balancing accuracy: Dynamic balancing is more accurate than static balancing. In other words, if static balancing is qualified, dynamic balancing may not necessarily be qualified; however, if dynamic balancing is qualified, static balancing is certainly qualified.

 In addition, in practical applications, factors such as the purpose and rotational speed of the workpiece must also be considered.
