Definitions
- the invention relates to a device for maintaining absorbency one arranged in a pump sump, screwless by means of a holder submersible pump attached to a foot elbow.
- the invention has for its object a device of the beginning to create the type mentioned, in which the maintenance of absorbency without an am Housing of the submersible pump to be made and with little effort measure to be retrofitted.
- a preferred embodiment of the invention has one for this purpose conical tapered bore in which a spherical or conical Closure body is arranged.
- the Bracket is equipped with an upward hole and a attached piping that goes into a manifold with a down directional opening passes, the opening through a floating Closure body is to be closed.
- the floating closure body by a movable on the manifold attached flap formed by the rising in the pump sump Liquid is pressed against the opening of the elbow.
- FIGS. 1 and 2 have the following features together:
- a submersible pump 1 is by means of a chain 2 attached to its top into and out of a pump sump (not shown here) draggable.
- the submersible pump 1 is guided with the aid of two wire cables 3, which are enclosed by a part serving as a holder 4.
- the holder 4 slides on the wire ropes 3 that it encloses.
- the bracket 4 has one or two claws 5, the last part the lowering process, the back of a flange 6 on a pipe bend 7 capture in order to then come to the fixed system on this back.
- This System also has the result that a surface located on the bracket 4 comes to the sealing system at the front of the flange 6.
- the ventilation line 9 is conical running hole formed.
- the vent line 9 is one Floating ball 10 is arranged, which drops as the liquid runs off and thus opens a path through which when the Liquid level the air in the housing of the submersible pump 1 can flow out. If the liquid level continues to rise, it presses the ball 10 on their seat formed in the ventilation line 9. The ventilation line 9 is now closed; leakage of liquid from inside the pump Pump sump is prevented.
- Vent line 9 available. But this turns into an elbow 11, which has a downward opening. In front of this opening there is one by one Hinge or a suspension made of a flexible material pivotable flap 12 arranged. With one falling below their level Liquid level, the flap 12 is moved downward by its own weight, whereby the previously closed opening is released by the flap 12. Thus, here too the vent line 9 is below the level of Closure body falling liquid level opened. The flap 12 is floating up so that they rise above their level Liquid level is closed again.
- the non-return element arranged in the vent line does not have to inevitably be equipped with a floating closure body.
- valves can also be used if there is relief open from the pressure of the liquid in the pump sump and thus a vent line release.

Claims (5)
- Einrichtung zur Erhaltung der Saugfähigkeit einer in einem Pumpensumpf angeordneten, mittels einer Halterung (4) schraubenlos an einem Fußkrümmer (7) befestigten Tauchmotorpumpe (1), dadurch gekennzeichnet, daß die Halterung (4) mit einer nach oben führenden Entlüftungsleitung (9) versehen ist, welche mit einem den Zutritt von Flüssigkeit aus dem Pumpensumpf in die Tauchmotorpumpe (1) verhindernden Rückschlagorgan (10, 12) ausgestattet ist.
- Einrichtung nach Anspruch 1, dadurch gekennzeichnet, daß in der Halterung (4) eine nach oben gerichtete Bohrung angeordnet ist, in welcher ein aufschwimmender Verschlußkörper (10) mit einem durch eine Verjüngung der Bohrung gebildeten Sitz dichtend zusammenwirkt.
- Einrichtung nach Anspruch 2, gekennzeichnet durch eine sich nach oben konisch verjüngende Bohrung, in welcher ein kugel- oder kegelförmiger Verschlußkörper (10) angeordnet ist.
- Einrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Halterung (4) ausgestattet ist mit einer nach oben gerichteten Bohrung und einer daran anschließenden Rohrleitung, die in einen Krümmer (11) mit einer nach unten gerichteten Öffnung übergeht, wobei die Öffnung durch einen aufschwimmenden Verschlußkörper (12) zu verschließen ist.
- Einrichtung nach Anspruch 4, dadurch gekennzeichnet, daß der aufschwimmende Verschlußkörper gebildet wird durch eine beweglich an dem Krümmer (11) befestigte Klappe (12), welche durch die im Pumpensumpf ansteigende Flüssigkeit gegen die Öffnung des Krümmers (11) gedrückt wird.
