What are the common terms for balancing machines? Many customers who need to do dynamic balancing purchase the equipment and the operators are not familiar with it, resulting in many problems and economic losses. In serious cases, it can also cause safety hazards. We have already learned about the dynamic balancing process and methods of balancing machines for different rotors through our article. Today, we will mainly share that to proficiently use a dynamic balancing machine, one must first be familiar with commonly used terms.
Technical guidance for using dynamic balancing machine
1. Unbalanced quantity:
The magnitude of the unbalance on a certain plane of the rotor does not involve the angular position of the unbalance balance. It is equal to the product of the unbalanced mass and its center of mass to the rotor axis, with the unit of unbalance being g.mm or g.cm, commonly known as the "weight diameter product".
2. Unbalanced phase
The angle value of the unbalanced mass on a certain plane of the rotor relative to the given polar coordinates.
3. Imbalance degree
The unbalance per unit mass of the rotor, measured in g.mm/Kg. In static unbalance, it is equivalent to the mass eccentricity of the rotor, measured in micrometers.
4. Initial unbalance
The amount of imbalance present on the rotor before balancing.
5. Allowable unbalance (also known as balance tolerance)
The remaining unbalance of the rotor allowed to ensure the normal operation of the rotor machinery.
6. Remaining unbalance
The remaining unbalance on the rotor after balance correction.
7. Adjust the radius
The distance from the center of mass of the corrected mass on the plane to the rotor axis is generally expressed in millimeters.
A balancing machine is an instrument used to measure the unbalance of a rotor, which is corrected based on its measurement results to improve the mass distribution of the balanced rotor and reduce the vibration of the shaft neck or the force acting on the bearings during rotor operation to a specified range.
