A fresh-water, vertical, axial-pump, stainless-steel impeller failed. The impeller was a single cast from stainless steel. A visual examination indicated that the fracture originated near the blade-to-hub attachment. During the investigation standard nondestructive and destructive methods were used. Specimens from the failed blades were taken for a material characterization. The goal of the examination was to determine a possible cause for the impeller-blade failure. After the examination it was determined that the most probable cause for the impeller-blade failure was the fatigue stress"},{"@xml:lang":"sl","#text":"Aksialne črpalke se uporabljajo za različne namene, kot so namakanje, hlajenje procesne opreme in komponent termoelektrarn. Lopatica rotorja vertikalno postavljene aksialne črpalke se je nepričakovano poškodovala. Lopatica in rotor sta bila ulita iz nerjavnega jekla kot celota. Vizualna preiskava rotorja je odkrila razpoko na vstopnem robu lopatice v bližini pesta. Med preiskavo vzroka nastanka poškodbe so bile uporabljene standardizirane porušitvene in neporušitvene metode. Iz lopatice rotorja so bili izdelani preizkušanci za karakterizacijo materiala. Namen preiskave je bil odkriti verjeten vzrok za poškodbo lopatice.
