Reitersberg Tunnel, Germany

The Project:

Reitersberg Tunnel of the Ebensfeld–Erfurt ICE rail link


Contractor:

Alfred Kunz Untertagebau

Swietelsky Tunnelbau

Leonhard Weiss


Tsurumi support:

Christian Kulik (Field Sales)


The Problem:

The 2975 m long tunnel is being cut using mining methods. After the snow melted, the water incidence in the tunnel suddenly rose to a maximum of 20 litres/second. The medium was made highly abrasive by its slurried stone content.


The Solution:

Massive drainage pump of types KTZ411 and KTZ611 (11kW) transport water over a distance of 500m to 1000m. The KTZ series is the perfect contractors' pump due to its good performance. The replacement of wearing parts is very simple. After training by qualified Tsurumi staff, all maintenance can be done independently on site.


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.
