How to eliminate the abnormal phenomenon of dynamic balancing machine
The dynamic balancing machine is a precision instrument that measures the size and position of the workpiece imbalance. The distribution of the mass of the balanced rotor has been improved so that the vibration of the journal or the unbalanced force of the bearing during rotation of the rotor is reduced to within a prescribed range. So how to eliminate the dynamic balance machine if there is an abnormal phenomenon? The following small series introduces you how to eliminate the abnormal phenomenon of the dynamic balancing machine.
1. Most of the measuring systems of dynamic balancing machines have a "self-checking" function, which can detect whether the measuring system itself is normal.
2. The angle of the unbalanced amount displayed by the dynamic balancing machine is always about 180 degrees or about 0 degrees. If there is a big difference, it may be that the dynamic balance machine has an abnormal condition.
3. When the dynamic balance machine has a large residual imbalance, the fault is not obvious. However, when the amount of residual unbalance is small, the angle at which the unbalance amount is displayed always changes when the balancer is started to enter the detection. Sometimes the angle changes within a certain range, and sometimes the angle changes within a range of 360 degrees. In order to reduce the same frequency, frequency doubling and frequency division interference, the support bearing shaft diameter should avoid the same or close to the outer diameter of the supporting roller or its integral multiple to avoid interference.
4. When the residual unbalance is too large, the fault is not obvious. However, when the amount of residual unbalance is small, the angle at which the unbalance value is displayed always changes by approximately 180 degrees, each time the measurement is restarted after balancing.
Through the above how to eliminate the abnormal phenomenon of the dynamic balancing machine, I hope to help everyone. If you have any other questions about the balancing machine, please feel free to contact us, we will be happy to help you, Guangzhou Zhuo Xuanjin Machinery Equipment Co., Ltd.!
