Abstract
En dobbel pakkboks omfatter et hus hvori er anordnet øvre (11) hhv. nedre (9) pakninger. Et hydraulisk stempel (13; 37) er innrettet til å sammentrykke pakningene slik at kan tette rundt en kabel eller vaier som befinner seg i pakkboksen. Et smøremiddel tilføres pakkboksen mellom de to pakninger for å presses inn i hulrommene i vaieren slik at pakkboksen blir trykktett. I en første utføringsform er stempelet (13) anordnet over det øvre stempel (13). I en andre utføringsform er stempelet (37) anordnet under det nedre stempel (9) og omfatter en flate (41) som påvirkes av brønntrykket.A double packing box comprises a housing in which the upper (11) or lower (9) gaskets. A hydraulic piston (13; 37) is arranged to compress the gaskets so that they can seal around a cable or wire which is in the stuffing box. A lubricant is applied to the stuffing box between the two gaskets to be pressed into the cavities in the wire so that the stuffing box becomes pressure-tight. In a first embodiment, the piston (13) is arranged above the upper piston (13). In a second embodiment, the piston (37) is arranged below the lower piston (9) and comprises a surface (41) which is affected by the well pressure.
