Add two more pictures! There are too few pictures
Weren’t there problems from the start? You can’t solve it unless you take it apart! Besides, even in complex equipment, it’s humans who install it!
If the bearing is damaged, simply replace it; there’s no need to disassemble the impeller assembly, or else replace it with a new one.
Isn’t the bearing inside the impeller assembly?
Don’t be afraid, OP; how can you learn if you don’t break it down? Use it as practice
Don’t be afraid; it’s very simple. Take it apart – start by removing the flat pull strip on the side
To find where the bearings of a multi-stage pump are located, one needs to check the drawings. Under normal circumstances, bearings at both ends of the multi-stage pump shaft are supported by separate bearing housings; in this case, there is no need to disassemble the impeller assembly. Between impellers, impeller clamps are commonly used for connection, which is a type of sliding bearing; this is probably what you are referring to. When performing maintenance, special attention must be paid to the fact that for each stage of impeller that is removed, it is necessary to number them individually and mark their left and right sides. This is done to ensure that the reinstallation time intervals remain roughly consistent; otherwise, it is very easy to wear out the impeller or even cause it to get stuck. After disassembly, inspect the impeller retaining ring and the casing mouth ring one by one; replace them if there are any issues. Another issue is the detachment of the housing mouth ring, which is often caused by damage to the anti-rotation pin. Depending on the situation, either replace the anti-rotation pin or carry out welding and grinding work
