This paper presents the principles of selecting drive engines for dredge pumps, formulated by this author. In order to formulate them influence of drive engines on dredge pump characteristics and dredger effectiveness, have been analyzed. Also, an analysis of results of the author’s operational investigations concerning energy consumption and parameters of excavated soil transport on board dredgers has been performed.
This paper presents proposal of a method for determining operational load parameters of dredge pumps, one of the crucial mechanical energy consumers on dredgers. The method based on results of the author’s operational investigations, deals with two main service states of dredge pumps on dredgers, namely: the state of loading the solid into soil hold (of dredger or hopper barge) and the state of pumping ashore.
This paper presents results of operational investigations dealing with dredge pumps, one of the most important mechanical energy consumers installed on dredgers. The investigations covered measurements of parameters which characterize the loads of dredge pumps in their two basic service states, namely during loading the spoil into a soil hold – hopper (of a dredger or hopper barge) and during transferring the spoil ashore.
