Kupplungsfuß für eine in einem Abwassersammelschacht angeordnete Tauchmotorpumpe, welcher ein Gehäuse aufweist, an dem außen ein Kupplungsteil für den Motor, ein Ausgangsrohranschluss und ein verschließbarer Reinigungsstuten ausgebildet sind, und in dem innen ein Rückflussverhinderer in Form einer Kugel und eines Dichtsitzes für die Kugel angeordnet sind. Die Kugel wird in einem Käfig für Vertikalbewegungen geführt ist und der Dichtsitz ist am unteren Ende der Vertikalbewegung der Kugel horizontal ausgerichtet.
摘要:
The invention relates to a suction connection, comprising a first flange (10) that includes a centrally located through hole (11) and is arranged to be connected to an outlet of a suction pipe and a second flange (12) that includes a centrally located through hole (13) and that is arranged to be connected to an inlet of a dry installed centrifugal pump. According to the invention the suction connection comprises a first pipe socket (15), which is displacable in the axial direction between an operative position in which said first pipe socket (15) disengageably connects the first flange (10) and the second flange (12) and thereby puts the through hole (11) of the first flange (10) in fluid communication with the through hole (13) of the second flange (12), and a service position in which said first pipe socket (15) is located at a distance from the second flange (12) and thereby admit access to the through hole (13) of the second flange (12).

Apparatus for moving radioactive waste (11) from a storage vault (13) to a second suitable container (28) by means of a flowing fluid, a flexible tube (1) being inserted in the storage vault (13) is connected to a suction device capable of maintaining a negative pressure in the tube (11), the suction device being located outside the storage vault (13), where the tube (1) comprises a plurality of manoeuvring devices (7a, 7b) surrounding the circumference of the tube (1) and extending in the longitudinal direction of the tube (1). A method of moving radioactive waste (11) from a storage vault (13) to another suitable container (28) by means of a flowing fluid is also described.

A submersible pump for pumping radioactive liquids comprises a pump cartridge (2) which is removably mounted in a cavity (3) formed in the pump body (1). Seals (30a, 30b) are provided between the cartridge (2) and the cavity (3). The cartridge houses a pneumatically operated motor to drive an impeller which discharges liquid through an outlet duct (10). Compressed air required for driving the motor is supplied through an air inlet tube (12) and air exhausted from the motor is conveyed through an air outlet tube (14). Both the air inlet and the air outlet tubes extend through the interior of the outlet duct (10).
摘要:
The invention concerns a submersible motor unit (1) designed to be secured in place on the floor of a liquid-filled container (2) and which has a specific gravity which is lower than that of the liquid concerned. Coupling elements (7, 8) are fitted on the motor unit (1) and on the floor of the container (2) so that the motor unit (1) can be detachably attached to the floor of the container (2) via a Bowden cable (11) which passes through the coupling element (8) fixed to the floor (4) of the container and which is attached to the motor unit (1), thus applying a force which counteracts the effect of buoyancy. In another embodiment of the invention, the motor unit has a ballast tank which can be filled with liquid.
