Assembly and method for attaching a liner to a pump module
Abstract
Fremgangsmåter og apparatur for å feste en sylinderfôring til en pumpemodul. Et spennlegeme er anordnet omkring den sylinderformede fôring og festet til pumpemodulen. Et låselegeme trer i inngrep med den sylinderformede fôring og gjenges til spennlegemet. En hydraulisk belastningscelle er løsbart festet til spennlegemet og omfatter et hydraulisk ramlodd anordnet for å påføre en trykkraft på den sylinderformede fôring og en strekkbelastning på spennlegemet. Låselegemet kan innstilles aksialt til kontakt med den sylinderformede fôring og for å opprettholde de påførte belastninger, som da virker som forbelastning for å bibeholde den sylinderformede fôring i kontakt med pumpemodulen.

Methods and apparatus for attaching a cylinder liner to a pump module. A clamping body is provided around the cylindrical liner and attached to the pump module. A locking body engages the cylindrical liner and is threaded to the tension body. A hydraulic load cell is releasably attached to the tension body and includes a hydraulic ram link arranged to apply a thrust to the cylindrical guide and a tension load on the tension member. The locking body can be adjusted axially to contact with the cylindrical guide and to maintain the applied loads, which then act as preload to maintain it.
