Generally, it is determined through comprehensive calculation based on the measurement frequency, product capacity, product rotor type, measurement and calibration time of the dynamic balancing machine.

It is very difficult to choose a suitable and desirable dynamic balancing machine from numerous manufacturers of dynamic balancing equipment, which is suitable for one's own rotor. But if you have a certain knowledge of dynamic balancing machines, you can start selecting good dynamic balancing machines. When you notice that the rotor is unstable due to imbalance, you must have a dynamic balancing machine. As for the quality issues you are worried about, continue reading the following answers and you will have a clear idea in your mind.
In the recent development process, it has been summarized that the standard for distinguishing whether dynamic balancing machines are excellent or not. Distinguishing the advantages and disadvantages of a dynamic balancing machine is not about looking at its appearance from the surface, but about the balance precision, quality, and practical application effects of the dynamic balancing machine.
How to judge the quality of a balancing machine when purchasing dynamic balancing equipment is not based on its appearance; It's about checking the balance accuracy, quality, and effectiveness of the balancing machine. Shenman Dynamic Balancing Machine Factory has compiled several key knowledge points for your reference.
1、 Determination of balancing machine accuracy
Assuming that the outer circle of the rotor is used as the calibration face of the workpiece:
1. First calibrate the balancing machine, and refer to the manual for the calibration steps
2. After the calibration is completed, use the balancing machine software to measure the imbalance of the workpiece;
For example, there is an imbalance of 20g at an angle of 100 degrees on the left side of the workpiece, and 30g at an angle of 150 degrees on the right side of the workpiece; At this point, find two 10g weights as test weights for verification, and add two 10g weights to the left at 100 degrees and the right at 150 degrees respectively; At this point, measure the imbalance again. If the imbalance on the left side increases by about 90% of the weight by 10g; The imbalance on the right side has increased by about 90% of the weight by 10g, indicating that the accuracy of the balancing machine meets the accuracy requirements and there is no problem with the balancing machine. On the contrary, there is a malfunction in the balancing machine equipment.
2、 Choosing a balancing machine also requires adjusting the parameters of the workpiece according to the balance. We need to know the size value of the workpiece that needs to be verified for dynamic balance, as well as the external dimensions and weights of commonly used workpieces.
1. Workpiece appearance: The balance machine equipment specification is selected as 1/2 to 1/3 of the middle mark, and the balance effect is better
2. Workpiece weight: It needs to meet the technical parameters such as the support distance between the swing frames of the balancing machine
3、 Rotor dynamic balance detection
A very important indicator for determining the quality of a balancing machine is the rotor inspection and processing; The value of the imbalance can reach a very small state, that is, after detection and processing, the vibration and noise of the rotor significantly disappear during operation. Choosing a satisfactory balancing machine not only requires looking at its appearance, but also understanding its balancing machine accuracy, balancing effect, and so on.
