How to judge the quality of a balancing machine when purchasing dynamic balancing equipment is not based on its appearance; It is to see the balance accuracy of the balancing machine, the quality of the balancing machine, the use effect of the balancing machine, etc. The technical specialist of Huake Zhichuang Dynamic Balancing Machine 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 on the left side of the workpiece at an angle of 100 degrees that needs to be removed, and 30g on the right side at an angle of 150 degrees that needs to be removed; 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, etc
