Conclusions
-
1.
A simple, reliable, and ecologically safe design of the drive of a submersible pump and associated devices was developed and thoroughly tested for wide modernization of existing and designing new dredges.
-
2.
The introduction of dredges with an additional submersible pump makes it possible to increase the depth of excavation, to increase the concentration of the mixture and productivity with a decrease of specific energy expenditures and equipment wear and increase of ecological protection.
