What causes the vibration of the high-pressure vortex fan and how to deal with it?
During the operation of the high-pressure fan, if the fan vibrates violently, it will affect its use effect, and with continuous shaking, if the fixation is not secure, it will shift and shift, and at this time, if it is used If it is hard-connected, it will affect the connection of the interface, and even bend, or the interface shakes open, and the destructive force is very large.
Moreover, if it cannot be effectively solved for a long time, then the performance will not be able to escape the fate of damage. Therefore, in such a case, it is better to give feedback in time and solve it in a timely manner.
I want to know why it vibrates. The reason is that the balance is broken, the balance is broken, the center of gravity is different, and the centrifugal force is different. Therefore, in order to apply this imbalance, jitter is inevitable.

1. If it is a new fan, more than 80% of this situation is the quality of the fan itself. The manufacturer did not test it well or did not test it before sending it directly to the customer. In this case, a new one needs to be updated. No other good idea.
Second, this situation occurs in use.
1. The bearing is damaged and the role of the bearing is clear. The fan uses high-temperature resistant high-speed bearings, which are generally not prone to problems. Unless it is used for a long time, the internal balls may wear out and age because the impeller is supported by the bearing Yes, if there is a problem, it will be transferred to the impeller, and then it will appear as an overall fan.
2. The impeller is damaged. The impeller is the least prone to problems. Unless there is something inside the fan or scraping occurs, this problem will occur, but the overview is relatively small and needs to be ruled out.
3. The use time is too long, and the holes used for balancing inside the impeller are too much dust, which destroys the internal balance, because it is impossible to maintain 100% balance without any treatment after the impeller is processed, so Need to rely on the dynamic balance machine to increase or decrease the material to maintain, this is why we will see that there are many small holes in the impeller. If there is more gray inside, because it is adjusted to rotate, the response will be doubled and enlarged. At this time, turn on the fan and clean it.
If all of the above are checked, and the problem is still not eliminated, then we can call our Beijing Meiqile Electromechanical Equipment Engineer to communicate online to resolve.
