Abstract

Corrosion (Erosion) it is inserted as an engineering problem for Centrifugal slurry pumps it plays an important role in design and operation of slurry transportation systems. In most slurry pump applications the monetary loss due to pump failure consists of loss of production rather than the cost of the pump, since the process must be when the pump fails. If the erosion rate can be estimated, the pump impeller (manufactured from brass) can be changed out in time, during scheduled maintenance, the present work reports experimental investigations on dependence of erosion wear of brass alloy in sand - water slurry. Systematic study on the failing impeller of a slurry pump used in irrigation has been carried out by means of scanning electron microscopy in order to clarify the Corrosion mechanisms. The results show, the weight loss of the impeller result of the collision of particles of liquid or solid surface-and continuously, generated stresses by the particles probably caused configure mortise on the surface as aresult of erosion wear. In this investigation, experiments were carried out to evaluate the wear resistance using wear test rig designed and manufactured for this purpose. Three specimens of different brass alloys were used, namely (CuZn2Ge-CuZn4Ge-CuZn6Ge) Discs manufactured from. The accumulated loss of weight was measured and the wear rates were determined for each Case material at constant normal test load of 20kg. Number of revolutions of tests equals (1000- 1500-2000) rpm. were selected for the three test materials respectively during wear tests .The accumulated loss of weight was measured as a function of the number of revolutions, Wear rate was calculated, Effect of Microstructure and Hardness of Brass Alloys, The results show Wear rate for material B3 (CuZn6Ge) is less than that of the wear rate for B2 (CuZn4Ge), B1 (CuZn2Ge) under the same testing conditions.
