Structure of centrifugal pumps
Thread Content
What is the relationship between the shaft, impeller, bearings, shaft sleeves, rotating ring, and stationary ring of a centrifugal pump?
Check the drawings; take a closer look when there is a chance to service the pump. A shaft, with an impeller attached to the shaft end; the sleeve is fitted over the shaft ； The inner ring of the bearing fits with the shaft sleeve ； The rotating ring is on the shaft sleeve and rotates together with it, while the stationary ring is fixed to the cover using anti-rotation pins, so it does not rotate. .
It seems like Xiaobai; I suggest searching for relevant posts on the forum to take a look. There are many pictures.
There is a lot of information in the forum summary post. Or find a book and study it thoroughly on your own first. If you don’t understand, come to the forum and ask again; otherwise, the question is too vague and no one will be able to give you a detailed answer

It is clearly explained in the centrifugal pump manual.
You can basically figure out 1, 2, 3 by searching on video websites for this advice; after working there for some time and having seen it done once, you’ll understand it right away
Having just started working, what the poster should do is read more books on centrifugal pumps, rather than coming here to ask such questions. It’s more intuitive when reading in a book; it’s not as hard to know where to start as here
