What factors influence the accuracy of rotor dynamic balance detection? Since all manufacturers of dynamic balancing machines have adopted the micro-computer technology, and now the micro-computer dynamic balancing detection technology has been very mature, the errors produced in the electronic measurement part have been negligible, and the relationship between the accuracy of the drive shaft balancing machine and the electronic part is very small.
The performance of dynamic balancing machine is basically independent of display method, but digital display is not only intuitive, but also has the highest reliability and is not easy to damage. It can also provide some practical additional functions, so digital display is the mainstream direction. Watt meters show that the method will gradually exit the market. There is also a balancer that uses a computer monitor. Its only advantage is that it is stylish and suitable for large users, but its complexity is many times higher, so its reliability will be greatly reduced (the more complex things are, the more likely they will fail). Small users should avoid choosing one.
When purchasing a dynamic balancing machine, pay attention to the following two points. Basically, you can find a suitable dynamic balancing machine for your rotor and buy it satisfactorily without using unjust money.
1. Connection mode of drive shaft and balancing machine.
2. Machining accuracy of balance machine spindle.
The dynamic balancer is divided into soft support and hard support. Compared with the two, the swing frame of the soft support balancer is relatively soft. During starting and stopping of the drive shaft, the soft-supported swing frame will vibrate obviously, but the hard-supported swing frame will not.
Theoretically, the soft-supported balancer can achieve higher test accuracy. However, this can only be distinguished in extremely sophisticated tests. For a propeller shaft balancer, the precision of the hard support far exceeds the actual requirements. If it is found that the accuracy of a propeller shaft balancer cannot meet the requirements, it must be the result of other factors. Soft and hard supports are only a minor factor in influencing the balance accuracy.
