Definitions
- Known submerged pumps which generally comprise a body comprising guide bearings for a shaft one end of which is driven by a motor, while the other end carries the propeller, the liquid being sucked from the side of the propeller and driven laterally from the engine side. These pumps do not allow delivery directly through a pipe.
- the pump according to the invention is of the type comprising a motor with a shaft guided in two bearings and on which a propeller is wedged, said motor being housed in a carcass comprising a first chamber filled with oil and provided with a first flange connected a second corresponding flange of a pump body, said pump body having a casing extending from the first flange to the propeller coaxially with the shaft and an openwork wall connected to a ring circumscribing the propeller and integral with a third flange to be connected to a discharge pipe and is characterized in that one of the motor bearings is offset longitudinally to be disposed in the pump body and supported by a support integral with the first flange, the first chamber of the carcass being in communication with a second chamber arranged in the support and opening onto the bearing, a turbine being wedged on the shaft in the second chamber and a return circuit to the pr first chamber being provided, so as to create a continuous circulation of lubrication through the bearing and an overpressure.
- the free end of the shaft 3 has a shoulder 10 extended by a part 11 which ends with a thread 7. On the part 11 is engaged the hub of a propeller 9 which is held by a blind nut 8 screwed on the thread 7.
- the truncated cone 18 is connected to an internal casing 20 by gussets 21, said casing having a frustoconical part 22 whose large base is integral with the flange 23 and a cylindrical part 24 which extends to the hub of the propeller 9.
- the carcass 2 comprises a conduit 27 which opens to the outside and which opens into a first chamber 28 which is closed by a partition 30 pierced with an opening 31 for the passage of the shaft 3.
- the opening 31 has a diameter greater than that of the shaft 3 so as to provide a passage 32 opposite which is wedged on said shaft 3 a small turbine 33.
- the screws 51 ensure the fixing of a plate 65 having a central opening 64 with a diameter greater than that of the shaft 3 while on this latter in front of the plate is fixed a turbine 66.
