Regarding the issue of pump shaft bending
Thread Content
During the maintenance of mechanical pumps, it is often necessary to adjust the straightness of the pump shaft. I’d like to discuss with the experts on the forum whether there is a standard approach Also, how to create a graph of curvature – it would be great if there were any books that could be recommended to my daughter, hehe~!
Currently, our unit rarely creates drawings for pump repairs
The purpose is to check whether the shaft is bent; this involves examining the main points of rotation (the impeller, coupling gears, mating surfaces, etc.), using a dial indicator. If the readings are within the standard range, that’s fine; otherwise, marks are made at the various high and low points to determine whether the shaft is roughly in a straight line or twisted. It’s easier to make corrections on a straight line; it’s more difficult when they’re not on a straight line.
So, is there no need for any plotting then?
