Embodiment 1
[0135] The working principle of the fluid centrifugal cross-flow action device provided in Embodiment 1 is: the centrifugal impeller 100 is driven to rotate by the driving source, so that the fluid is input from the inlet (or called the inlet) of the centrifugal cross-flow guiding cylinder 200; the fluid is driven by the centrifugal impeller 100 function, so that the fluid reaches the diversion surface of the diversion structure 210 in the direction perpendicular to the axis of the centrifugal through-flow cylinder 200; under the structural diversion effect set by the diversion surface of the diversion structure 210, the fluid will flow from The direction perpendicular to the axis of the centrifugal through-flow guiding cylinder 200 becomes the flow around the axis of the centrifugal through-flow guiding cylinder 200 or the flow parallel to the axis of the centrifugal through-flow guiding cylinder 200, thereby obtaining a fluid centrifugal through-flow action mode.

Description
technical field [0001] The invention relates to fluid action technology, in particular to a centrifugal through-flow water craft propulsion device and its application. Background technique [0002] The flow of fluid (including air flow and liquid flow) can only be realized by the action of a fluid action device. Fluid action devices can be divided into two types: drive air flow fluid devices and drive liquid flow fluid devices according to different working fluids. There are many types of practical applications for driving air flow fluid devices and driving liquid flow fluid devices, but turbine fluid centrifugal impellers and axial flow impellers are the most widely used. The turbine fluid centrifugal impeller and the axial flow impeller take the axial flow centrifugal impeller and the axial flow impeller and the centrifugal centrifugal impeller and the axial flow impeller as the core. [0003] A water body refers to a ship or a submarine. At present, the propulsion devi...
