How do you Know experimentally the usefull life of the shaft of the centrifugal pump subjected to fatigue?, does some test exits?

RE: How do you Know experimentally the usefull life of the shaft..........

Pereira,

Have you tried contacting the pump manufacturers?  They might be able to offer you some fatique calculations etc.

RE: How do you Know experimentally the usefull life of the shaft..........

Your question is a little vague, the mechanism of fatigue is very complex. If your pump shaft has been manufactured by the pump manufacturer and you are operating the pump within the specifications stated by the manufacturer i.e fluid, speed, protection, etc then I would expect the pump manufacturer has already considered fatigue as a failure criterion. They will!! have selected an appropriate material, considered the loading applied, accounted for any stress raisers on the shaft etc.
All in all there should be no worries!!
Note that fatigue tests have been carried out for many different materials under various kinds of load, hence engineering practice relies heavily on this emperical data.
I expect your pump shaft will have been conservatively designed to never reach what is known as its "endurance limit" assuming it is made of ferrous material.
Hope this helps
