Walter Zuppinger

from Wikipedia, the free encyclopedia

Walter Zuppinger (born June 21, 1814 in Männedorf ; † November 16, 1889 in Eschenz ) was a Swiss engineer and industrialist . He is best known as the inventor of a water wheel known as the Zuppinger wheel .

Live and act

After completing his apprenticeship, Zuppinger found a job at the Zürcher Maschinenfabrik Escher, Wyss & Co. and rose to a management position. Between 1856 and 1859, as Escher's confidante, Zuppinger set up a branch for Escher-Wyss in Ravensburg (today Andritz Hydro ) and was director there for a long time.

By expanding hydropower as the basis for industrialization in Upper Swabia , Zuppinger acquired a high reputation in the region. Among other things, Zuppinger was a co-founder of the Baienfurt paper mill near Ravensburg. For his services and his expertise, he was appointed the Württemberg building officer. A street in Ravensburg is named after Zuppinger.

Zuppinger turbine and Zuppinger water wheel

Between 1838 and 1844 Zuppinger worked for Escher-Wyss on the development of new types of water turbines . The result was the “tangential wheel”, also known as the Zuppinger turbine. It was a partially pressurized constant pressure turbine with a flow from the outside in. Their area of ​​application is now covered by Pelton turbines .

His best-known construction from this period is the water wheel named after him (patented 1849), which was based on the predecessor of Poncelet and Sagebien . The Zuppinger wheel is a medium to undershot crop wheel with involute-shaped curved blades, which not only use the hydrostatic but also the dynamic pressure of the water and thus achieve a higher degree of efficiency . Technically, the wheel is a transition form from the water wheel to the water turbine.

Since the wheel works effectively on low gradients (0.5 - 2 m) and without complex control even with strongly fluctuating water quantities, it is still used today as an alternative to the turbine in water mills and small hydropower plants under such operating conditions .
