Abstract
A waste water lifting installation includes a collection container (2) and a flange plate (4) which is arranged on the upper side of the collection container (2) and on which a level switch (12) immersing into the collection container (2) is attached. At least one run-in pipe (22), departing from the flange plate (4), extends vertically downwards into the collection container (2) and has such a vertical length that the lower end (28) of the run-in pipe (22) is vertically distanced further from the flange plate (4) than a lower end of the level switch (14).
Claims19
A waste water lifting installation comprising:
- a collection container;
- a flange plate arranged on an upper side of the collection container;
- a level switch attached to the flange plate and extending into the collection container;
- a run-in pipe extending from the flange plate vertically downwards into the collection container, the run-in pipe having a vertical length such that a lower end of the run-in pipe is vertically distanced further from the flange plate than a lower end of the level switch;
- two additional run-in pipes to provide a multiplicity of run-in pipes arranged on the flange plate and extending from the flange plate into the collection container, wherein the run-in pipes have a vertical length such that a lower end of each of the run-in pipes is vertically distanced further from the flange plate than a lower end of the level switch when the level switch is in its lowest position, wherein each of said run-in pipes is formed integrally with the flange plate.
A waste water lifting installation comprising:
- a collection container;
- a flange plate arranged on an upper side of the collection container;
- a level switch attached to the flange plate and extending into the collection container;
- a plurality of run-in pipes extending from the flange plate vertically downwards into the collection container, each of said run-in pipes having a vertical length such that a lower end of each of said run-in pipes is vertically distanced further from the flange plate than a lower end of the level switch when the level switch is in its lowest position, each of said run-in pipes being integrally connected with said flange plate to form a one-piece flange plate and run-in pipes structure.
A waste water lifting installation comprising:
- a collection container;
- a flange plate arranged on an upper side of the collection container;
- a level switch attached to the flange plate and extending into the collection container;
- a first run-in pipe;
- a second run-in pipe;
- a third run-in pipe, each of said first run-in pipe, said second run-in pipe and said third run-in pipe being located opposite another one of said first run-in pipe, said second run-in pipe and said third run-in pipe, each of said first run-in pipe, said second run-in pipe and said third run-in pipe having a vertical length such that a lower end of each of said first run-in pipe, said second run-in pipe and said third run-pipe is vertically distanced further from the flange plate than a lower end of the level switch when the level switch is in its lowest position, each of said first run-in pipe, said second run-pipe and said third run-in pipe being integrally connected with said flange plate to form a one-piece flange plate and run-in pipes structure, each of said first run-in pipe, said second run-in pipe and said third run-in pipe defining at least a portion of a fluid flow system, wherein fluid is delivered to said collection chamber via one or more of said first run-in pipe, said second run-in pipe and said third run-in pipe.
