چکیده مقاله :
In this paper, the reasons of damage water pumps parts of the air compressor cooling system were studied. To reach this goal, the works like preparing metallographic samples, evaluation of structure, investigation of mechanical properties, the alloy parts detection and chemical analysis of deposit and corrosion products collected from the parts were performed. According to studies and results obtained, alloys suggested to be used in the impeller and casing are gray cast iron with flake graphite (random distributed) and ductile iron with spherical graphite (distributed almost uniformly), respectively. Also cause damage to the pump impeller, graphitic corrosion was described.
