Conclusions
-
1.
For the first time in Russia a submersible axial-flow dredge pump was developed and tested for installation as a first-stage pump on dredges to reduce the negative pressure before the hold dredge pump and to increase its positive suction head.
-
2.
The use of the axial-flow dredge pump permits increasing the output of the dredge and depth of excavating the underwater borrow pit. With respect to power consumption the axial-flow pipe is 2–3 times more economical than ejection.
-
3.
The small mass of the pump permits mounting it on existing dredges without their alteration.
-
4.
Development and perfection of this direction is quite prospective for hydraulicking.
