THE RELATIVE INFLUENCE OF SOME VARIABLES ON THE PERFORMANCE OF A HYDRAULIC PIPELINE DREDGE MODEL

A computer based model of a hydraulic pipeline dredging system has been developed and is employed to study the relative influence of major independent variables such as pump characteristics (both performance and cavitation); drive horsepower available; sediment size; and suction pipe size. These varialbles are examined in terms of their effects on solids output for a wide range of pumping distances and digging depths using three representative dredge sizes. The advantage of the model is that one parameter can be systematically varied while all others are held constant and the results quickly and economically compared. The results demonstrated that the 'one dredge pump is as-good-as another' (hydraulically) hypothesis must be rejected. Substantial differences in production were demonstrated for both the horsepower and cavitation limitations on solids output for the various pumps studied.
