Abstract
A test method has been developed to rank the erosive wear of the vanes of a centrifugal--model-dredge-pump. The test allows to distinguish between leading edge erosive wear and sliding erosive wear of the vanes using specially designed moulds for the leading edge. The centrifugal model-dredge-pump with a dismountable impeller enables to measure the wear of the vanes individually as well at the leading edge as on the surface with respect to the working point of the pump. At the beginning a solid-liquid mixture of quartz sand and water with a solid concentration of 30 by volume was used. It was followed by a mixture of furnace slag and water with the same concentration. The effect of variables on the erosive wear rate, such as type of solid material and flow rate, can be correlated for the material weight loss of the vane. Advantages of this method are the simplicity and the possibility of wear ranking, with acceptable results.
