The impeller of Roots blower is corroded, should it be replaced or repaired?

The impeller of Roots blower is corroded, should it be replaced or repaired? It is normal that the impeller of Roots blower is corroded, which is affected by factors such as transmission medium, impeller material, fan health, etc., such as:

1. Conveying medium

The transmission medium of Roots blower is corrosive, or there is a large amount of water vapor, which may corrode the impeller;

2. Impeller material

The quality of the impellers made from different foundation steels is different. The ones with good quality are not easy to be corroded, while the ones with poor quality are easy to be corroded. Click to view the image and text: the difference of impeller materials. The corrosion resistance of ordinary cast iron and stainless steel is also different. The corrosion resistance of stainless steel is better than that of ordinary cast iron fan.

3. Fan health

If the fan has its own fault and the impellers rub against each other, or the impeller casings rub against each other, the serious friction will rub off the protective layer on the impeller, resulting in corrosion.

When the impeller is corroded, many friends will have questions about whether we should replace the fan impeller or repair the fan impeller. In view of this situation, Xinqian Shun Fan has the following suggestions:

1. When the fan impeller is slightly corroded, the fan impeller shall be sprayed for protection to extend its service life;

2. When the impeller is severely corroded, we recommend replacing the fan impeller;

3. Impeller corrosion is associated with other parts. Impeller damage may also be associated with casing, bearing, wallboard, gear, and motor damage. Large scale damage may occur. We recommend replacing the fan directly, especially the motor damage caused by the impeller. We recommend replacing the new equipment.

For users who replace fans, when replacing fans, we should understand the main reasons for corrosion of fans. When purchasing next time, we should solve the corrosive problems in a targeted way. If there is corrosive gas in our own working conditions, we will choose stainless steel, which has strong corrosion resistance, to avoid corrosion problems again. As for corrosivity, Xinqian Shun Fan mentioned in the previous article. If you want to know about it, you can click here to go directly to: Fan Corrosion
