Original 3D concept

Small hydropower plants

A horizontal Francis unit with a spiral casing, guide vane mechanism, shaft, coupling and generator on a common frame. M8 and M16 fastener assemblies can be inspected close up.

Objects and equipment

In 3D: viewpoints, keyboard or on-screen walking controls, roof visibility and object dimensions on click. The interface is in Russian.

NAEVI references and model accuracy

NAEVI presents smarT modular plants on a frame or in a container. This establishes the solution family. Our scene is an original horizontal Francis layout, not a replica of a particular factory product.

Supported by sources

NAEVI describes smarT up to 1 MW and HEROS automation. GLOBAL Hydro documents a Francis Container and the operating Shakhimardan example: two turbine containers and a separate electrical container. These specifications belong to the references.

Refined in the model

The levers and ring have a steel finish. The scene includes a hydraulic cylinder, joints, support, power unit and two hydraulic lines. Revision 12 refines enamel and metal finishes, hose ferrules, the fan grille and tank joints. Actuator force, stroke and dynamics have not yet been calculated.

Requires engineering review

Head and flow, runner selection, pipe and flange pressure ratings, fastener and support calculations are needed. The draft tube outlet intersects the solid floor; the sump, tailrace connection and maintenance clearances require revision. Scene dimensions are not for fabrication.

Flanges: a dimensional mismatch

The external flange in the model has a 720 mm diameter, a 628 mm bolt circle and 12 M16 bolts. The INDURA DN500 PN10 product has a 670 mm diameter, a 620 mm bolt circle and 20 holes of 26 mm. Our assembly does not match that product. PN10 has not been assigned to this project: pipe, flange and fasteners require coordinated selection for the design pressure.

NAEVI’s first illustration shows a bucket runner; its geometry must not be transferred to a Francis turbine. Lever materials follow Hydro Tinck’s description, a separate manufacturer, and do not establish NAEVI’s supplied specification.
