Abstract
A sealing ring packing (1) includes a cooled packing casing (4) that can be placed inside a stuffing box borehole (3), and holds at least one essentially annular slide ring (5) pressed against the moved component (2) to be sealed, whose outside periphery (11) exhibits at least one heat transfer sleeve (9) expandable until resting on the inside periphery of the stuffing box borehole (3) when inserted, and which is otherwise not separately cooled. This makes it possible to avoid the disadvantages of a separate liquid cooling in this area without impermissible temperature rises.
Claims8
Sealing ring packing for sealing passage of a reciprocating piston rod of a reciprocating compressor, including a cooled packing casing that can be placed inside a stuffing box borehole and holds at least one essentially annular slide ring pressed against the reciprocating piston rod to be sealed, wherein an outside periphery of the packing casing includes at least one heat transfer sleeve which is radially expandable in order to contact an inside periphery of the stuffing box borehole when inserted to transfer heat to the stuffing box, and is otherwise not separately cooled.
