Seeking help with dust accumulation on the compressor impeller
Thread Content
Our workshop has a Kaifeng Air Separation H210 type air compressor. Every time it is opened for maintenance, the first-stage impeller is heavily covered in dust, which accumulates at the inlet; the manufacturer says this is caused by dirty air. But the same filter bags are also used in Shen’s H-type air compressors, and this problem does not occur when they are in use. I believe the issue lies in the flow channels – the sealing at the inlet narrows, which creates eddies in the areas where dust accumulates. Please help analyze whether this is indeed the cause.
The design doesn’t think so; it says it’s a problem with the filter bag
It’s too complicated; I can’t understand the professional drawings
