Abstract

Die Pumpeinrichtung umfasst eine Pumpe (22), eine Ansaugein­ richtung (7) und einen Ansaugbehälter (1). Die Ansaugein­ richtung (7) ist als Bauteil ausgebildet und koaxial von oben in den Ansaugbehälter (1) einsetzbar. Die Pumpe (22) ist ebenfalls als Bauteil ausgebildet und von oben mit selbstzentrierenden und selbstdichtenden Anschlüssen (15,31) koaxial in einen Hohlraum (21) der Ansaugeinrichtung (7) einsetzbar und an diese anschliessbar. Ueber Gewindebol­ zen (6) die beim Absenken der Ansaugeinrichtung (7) Bohrun­ gen (20) in einem Ringflansch (8) derselben durchsetzen, kann die eingesetzte Ansaugeinrichtung (7) erforderlichen­ falls durch fernbediente Manipulatoren mit dem Ansaugbehäl­ ter (1) verbunden werden. Analog treten vom oberen Ende der Ansaugeinrichtung (7) vorragende Gewindebolzen (17) beim Einsetzen der Pumpe (22) durch Bohrungen im Gehäuse derselben, sodass auch die Pumpe mittels fernbedienbarer Manipulatoren in ihrer montierten Lage fixiert bzw. aus dieser gelöst werden kann. The pump device comprises a pump (22), an intake direction (7) and a suction tank (1). The suction direction (7) is designed as a component and coaxial from can be inserted into the suction tank (1) at the top. The pump (22) is also designed as a component and with from above self-centering and self-sealing connections (15,31) coaxially into a cavity (21) of the suction device (7) can be used and connected to this. About threaded bolt zen (6) when lowering the suction device (7) push through gene (20) in an annular flange (8) thereof, the suction device (7) used may be required if by remote-controlled manipulators with the suction container ter (1) can be connected. Analog step from the upper end threaded bolts (17) projecting from the suction device (7) when inserting the pump (22) through holes in the housing same, so that the pump can also be operated by remote control Manipulators fixed in their assembled position or out this can be solved.

Die Demontage und Wiedermontage der Pumpvorrichtung zwecks Reparaturen und Wartung kann somit schnell und einfach auch über fernbediente Manipulatoren erfolgen, wobei beim Zerlegen oder infolge eines Defekts auftretende Leckage stets im Ansaugbehälter (1) verbleibt. The disassembly and reassembly of the pumping device for the purpose Repairs and maintenance can thus be quick and easy also take place via remote-controlled manipulators Disassemble or leakage due to a defect always remains in the suction tank (1).
