Benefits of technology

The invention provides a simpler and less costly method for pumping liquid from a spent liquid pipeline. This method allows the liquid to flow from the spent liquid inlet to the outlet by gravity, and it involves the following steps: Overall, this method simplifies the process of pumping liquid and reduces the complexity of the pumping area.

Problems solved by technology

It is fairly complex to use; its incorporation in a pumping area is also fairly complex; finally, its incorporation in a pumping area is costly.

Embodiment Construction

[0075]FIG. 1 shows a preferred version of the pumping station 3 according to the invention, incorporated in a pumping area 8. This pumping area 8 comprises a well 4 such as a pebble trap. A pebble trap is known to those skilled in the art. It is generally a cylindrical cavity with a diameter generally between 50 cm and 2 metres (with a preferred value of 1 metre) and with a height that is generally between 50 cm and 9 metres (with a preferred value of 5 metres). Spent liquid (for example spent waters) is generally brought to a pebble trap 4 via one or more recovery pipeline(s) 40. Preferably, the bottom of the pebble trap 4 is situated approximately 1 metre below the intake of said recovery pipeline 40 situated at the level of said pebble trap 4. Spent liquid can convey stones, pebbles or particles with a density that is higher than the liquid transporting them. When this spent liquid reaches the pebble trap 4, these higher density particles have a tendency to fall to the bottom by ...

Abstract

Pumping method, pumping station, and pumping area Method for pumping liquid from a spent liquid pipeline (10) and comprising the steps of: providing a first pump (501), providing a junction pipeline (15), mechanically coupling said junction pipeline (15) to said first pump (501) and to said spent liquid pipeline (10) for allowing liquid to flow from said spent liquid pipeline (10) to said first pump (501). The method is characterized in that said first pump (501) is a self-priming pump.

Description

[0001]The invention relates to the technical field of pumping stations and pumping areas for liquid. More specifically, the invention relates, according to a first aspect, to a method for pumping liquid. According to a second aspect, the invention relates to a pumping station, and according to a third aspect, to a pumping area.STATE OF THE ART[0002]FR2837244 describes a pumping station which can be used to pump or raise spent waters from connecting underground pipelines to the surface of the ground. This pumping station comprises one (or more) pump(s) which is (are) housed in a tank. This tank comprises an inlet opening into which is introduced an intake pipeline (or spent liquid pipeline) conveying, for example, spent waters from a gravity network. The spent waters leaving the intake pipeline are poured into a main duct towards the pump or pumps which can direct these waters by pumping to an outlet pipeline.[0003]The pumping method and the pumping station of FR2837244 present some ...
