How does the impeller aerator swing up and down during operation?

The reasons why the impeller aerator swings up and down during operation are as follows:

1. Unstable: The aerator is not installed smoothly or the frame is unstable, which causes the machine to shake during operation.

2. Impeller imbalance: Impeller imbalance of aerator will cause the machine to swing up and down during operation.

3. Water quality problem: If there are impurities in the water quality, it will block the impeller, affect the normal operation of the aerator, and cause the machine to swing up and down during operation.

4. Motor failure: The motor failure of the aerator will cause the machine to swing up and down during operation.
