Experimental Problems of New Constructions of Portable Submersible Pumps for Mining with Electric Motor Cooled by Water Jacket

Abstract: The article presents a new construction of a submersible pumping engine where new original solutions in flowing system and control system where introduced It let obtain high efficiency and fulfill user's expectations. The article also contains experiments of the new pumping engine and their results. The results of numerical analysis of the movement of liquid in flowing channel is described and the analytical characteristics are compared with ones measured in laboratory. The work also presents the problems with… Show more
