What are the methods for positioning multi-stage pump impellers? What are the different structures of open rings? Let’s exchange ideas! ! See which design is the most reasonable.
1. All impellers and shaft sleeves are tightened by the final nut； 2. All impellers and shaft sleeves are positioned by the final split snap ring; they are not compressed, with a slight gap between them ； 3. Each impeller is individually positioned by a split snap ring or an open snap ring, with a transitional fit ； 4. Each impeller is fitted using a tight interference fit; clamps can be used as an aid, or they may not be used at all.
Positioning methods include: steps, clamping rings, and interference fit
