The invention concerns a Wells turbine, comprising a hub with a plurality of rotor blades having a drop-shaped profile orienting from a profile nose;

Wells turbine having passive rotor blade displacement

The invention concerns a run-of-river power plant with the following components or features:

Run-of river power plant

A cover for turbines or pumps, which is substantially less expensive than a cover having a cast construction. The cover is made of welded metal plates in a shape which generally corresponds to that of Kaplan type turbines, pumps or the like, and includes a number of thick walled rings and shells having a conical shape or envelope. The cover comprises a flat radial ring which is supported between the outer covering of the machine and a first, conical, axially-extending shell which concentrically surrounds the shaft of the machine, and tapers narrower toward the runner of the machine which is rotated by the shaft. A second shell is also conical, defines a lesser conical angle than the first shell, and extends from an exterior region of the first shell and toward the runner. A radial bearing is mounted on the first shell for supporting the shaft.

The cover is made of welded metal plates in a shape which generally corresponds to that of Kaplan type turbines, pumps or the like, and includes a number of thick walled rings and shells having a conical shape or envelope. The cover has a flat ring which is supported between the outer covering of the machine and a first, conical shell which surrounds the shaft of the machine and tapers narrower toward the runner of the machine. A second shell, also conical, defines a lesser conical angle than the first shell. It extends from the exterior of the first shell and axially toward the runner, surrounding the shaft, and is disposed for directing radially inward water flow axially toward the runner. At least one bearing is mounted between the flat ring and the shaft. The flat ring and the first and second shells are sheet metal and are welded together.

A device for building up a workpiece of any shape by deposit welding comprising a support device for the workpiece and a welding head for depositing the filler material. A form shoe is arranged on both sides of the workpiece wall that it being built up. Each form shoe is movable independently from the other one and transverse to the workpiece wall. The welding head is reciprocably mounted between the form shoes. There is provided a device for producing relative movement between the support device with the workpiece and/or the welding head and the form shoes.
