The problem:


Shafts with a pronounced tilt. drilling water and incoming water must be pumped out.


Our solution:


LH322W submersible pump is used, with a second pump held in reserve. The pump is frequency-controlled and regulated using a submersible pressure probe. If the water level rises, the speed is increased; when the water level falls, the speed is reduced. This type of control was chosen so that a very small pump container can be used which can be easily replaced after each new tunnel section. A model KTZ47.5 pump is built into the drainage water treatment.

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.
