Impellers are an important part of industrial fans. High-quality impellers can even be used for more than ten years. In the production process of the impeller, there are always many problems, so what are the common failures of the impeller? How can we repair it so that it can continue to work?
1. Casting defects
Failure performance: Inclusion in the flow channel; not smooth; trachoma; cracks, etc.
Treatment method: Remedial methods such as grinding and welding can be carried out according to the actual situation, but if the problem is serious, it can only be returned to recast.
2. Abrasion
Failure performance: Impeller improperly selected materials or pump type selection, resulting in impeller surface contamination and corrosion
Treatment method: replace the impeller of other materials, check the process materials during use, and reduce the erosion of industrial pollution
3. Cavitation
Failure performance: improper design scheme; too high installation position; improper material selection, etc.
Treatment method: reduce the installation location; use better materials that can resist cavitation; redesign
This is the first three types of impeller failure problems encountered by manufacturers in the production process. If you want to know more, please visit Suzhou Sanda Precision Mold Manufacturing Company!
