The Project:


Extension of the pumped storage power station at Vianden by an 11th machine, Lot 1 – Structural installations, Luxemburg


Companies involved:

Ed. Züblin AG, IU Directorate – Tunnel Construction, Stuttgart

Strabag AG, IQ Directorate, Vienna

Jäger Bau GmbH, Schruns


The largest pumpe storage power station in Europe in the township of Vianden in Luxemburg, with a peak capacity at the present time of 1,100 MW, is being extended by a further turbine with a capacity of 200 MW.

The construction work includes the carcasse work for the cavern, as well as the access galleries, shafts, and intake and outlet structures.


The Problem:


Tunnel construction in particular is where pumps are in most cases required to work under especially difficult conditions. This is why the sites have their own workshops, where machinery and equipment can be repaired and maintained. In this situation, simple maintenance of the pumps is an important consideration in ensuring long and trouble-free operation.


The Solution:


Training the workshop personnel, with the aim of enabling them to carry out the maintenance and repair of Tsurumi pumps themselves.

U slučaju abrazivnih i korozivnih primjena, normalno je da će se u određenim komponentama dogoditi snažnije trošenje. S obzirom na gornju primjenu trošenje se može odvijati uglavnom u radnom kolu, miješalici, usisnoj ploči, rukavcu osovine, uljnom prstenu, mehaničkoj brtvi, kućištu pumpe, cjedilu, kućištu motora i ispusnoj spojki. Ovisno o radnim uvjetima vijek trajanja tih dijelova može značajno varirati i može biti kraći od pravnog zakonskog razdoblja.
S obzirom na to pridavajte pažnju našim općim uvjetima koje vam također šaljemo e-poštom na zahtjev.
