Abstract

The present invention relates to an axial flow multistage turbine, comprising: a housing defining an inlet and an outlet so as to enable fluid to flow therein; a rotating shaft rotatably installed in the housing; a front impeller installed on the rotating shaft and perforated so as to define a plurality of through-openings for guiding the flow of fluid therethrough and rearward; and at least one rear impeller fixed on the rotating shaft behind the front impeller, and defining at least one guide groove for guiding fluid in a rotating direction of the rotating shaft to rotate the rotating shaft, and having a rear outlet at an end of the guide groove for generating rotational force by means of the rearward discharge of fluid flowing along the guide groove. The axial flow multistage turbine according to the present invention is easy to install and manufacture, enabling a reduction in installation costs, and the loss of fluid flowing in the housing is minimized to provide the advantage of increased power-generating efficiency of the turbine.
