When you find that the workpiece is vibrated due to imbalance and the quality of the product is reduced, you need to purchase a balancing machine. However, it is more difficult for a friend who is not familiar with the balance machine to choose a cost-effective balancing machine. But if you have a certain balance machine knowledge, you can start to choose a good balance machine, then what should we judge the quality of the balance machine?
Today, Xiaobian will tell you about the criteria for determining whether a balancing machine is a good product. To judge the quality of a balancing machine, it is not to look at its appearance from the surface, but to see the balance accuracy of the balancing machine, balance the quality of the machine, and balance the use of the machine.
First, the determination of the balance machine accuracy
Assume that the outer circle of the rotor is used as the correction surface of the workpiece:
1. First calibrate the balancing machine. See the instructions for the calibration procedure.
2. After the calibration is completed, the unbalanced amount of the workpiece is measured by the balancer software. For example, the left correction surface of the workpiece has an unbalanced amount of 20g at an angle of 100 degrees, and the right correction surface has 30g at an angle of 150 degrees. At this time, find two 10g weights as the test weights. Add two 10g weights to the left 100 degrees and the right 150 degrees. Then measure the unbalance, if the left side is uneven. Measured by 10% of the weight of 10g, the unbalance on the right side increased by 10% of the weight of 10g, which means that the accuracy of the balance machine meets the accuracy requirements, and the balance machine is no problem. Otherwise, the balancing machine device is faulty.
Second, the balancing machine accuracy grade division
Choose the right balancing machine from the balance accuracy
The balancer is also required to correct the parameters of the workpiece according to the balance. We need to know the extreme values of the workpiece size that need to check the dynamic balance and the size and weight of the common workpiece.
Workpiece shape: The balance machine equipment specification is selected as the intermediate mark 1/2 to 1/3 balance effect is good
Workpiece weight: technical parameters such as support distance between the balancer's swing frame
To determine the quality of a balancing machine, a very important indicator is that after the rotor is detected, the value of the unbalance can reach a minimum state, that is, after the detection and treatment, the vibration and noise of the rotor disappear obviously during operation.
All in all, choosing a satisfactory balancing machine is not only a matter of looking at the appearance, but also understanding the accuracy and balance of the balancing machine.
