Pumped Storage Power Station, Vianden, Luxemburg

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 pumped 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 carcase work for the cavern, as well as the access galleries, shafts, and intake and outlet structures.


The Problem:


Fresh water supply by means of submersible pumps for the washing area, drill carriages, etc. Keeping the water clear by means of submersible pumps during the driving of the tunnel.


The Solution:


Use of Tsurumi dirty water pumps of widely differing types: KTZ22.2, KTZ35.5, KTZ47.5, tough, robust pumps in cast iron design for clearing water from the drift or heading face, KRS2-150 with stirring mechanism for sludge disposal, and LH25.5W high-pressure pump for removing water from the entire tunnel stretch.

No caso de uma utilização abrasiva e corrosiva, certos componentes sofrerão um desgaste natural. No que respeita à aplicação anterior, o desgaste pode decorrer sobretudo no impulsor, agitador, placa de sucção, manga do veio, anel de óleo, vedação mecânica, revestimento da bomba, filtro, revestimento do motor e acoplamento de descarga. Dependendo das condições de trabalho, a vida útil daquelas peças pode variar significativamente e pode ser mais reduzida do que o período legal da garantia.
