The invention relates to a marine meachanical seal arrangement comprising a first mechanical seal () comprising a first rotating slide ring () and a second stationary slide ring () defining a first sealing gap () between their two sliding surfaces (), a second meachanical seal () comprising a second rotating slide ring () and a second stationary slide ring (), which define a second sealing gap () between their sliding surfaces (), a barrier circuit () comprising a barrier fluid cavity () which is arranged between the first mechanical seal () and the second mechanical seal () and is filled with a barrier fluid, the barrier fluid cavity () being divided into a first sub-cavity () and a second sub-cavity (), the first subcavity () and the second subcavity () being separated by a flexible lip seal () wherein the second sub-cavity () is arranged at the second mechanical seal (), and wherein the lip seal () is arranged such that a flow of barrier fluid from the first subcavity () into the second subcavity () is allowed and a flow of barrier fluid from the second subcavity to the first subcavity is prevented. (FIG.)

Marine slide ring seal arrangement

A mechanical seal arrangement includes a first mechanical seal with a rotating slide ring and a stationary slide ring, which define a sealing gap in between them. The mechanical seal arrangement includes a first sealing space that is filled with a sealing liquid. The first mechanical seal seals off the sealing space against a surrounding area, a first piston arrangement with a piston element and flexible wall areas that define a first piston interior space, wherein the first piston interior space is in fluid connection with the first sealing space. A piston outer surface of the piston element is in fluid connection with the surrounding area, and a first pre-stressing appliance that exerts a first preload force (F) on the piston element of the first piston arrangement.

Mechanical seal arrangement and well bore conveyor device

The invention relates to a drive device () for water vehicles comprising a propeller (), a drive mechanism () for driving the propeller (), and a magnetic coupling () which is arranged between the propeller () and the drive mechanism (), wherein the magnetic coupling () comprises an outer magnetic element (), an inner magnetic element () and a can (), and wherein the can () is arranged between the inner magnetic element () and the outer magnetic element ().

Drive device for water vehicles

A divided driver device () for a mechanical face seal for non-rotatable assembly on a rotary component and for the transmission of a torque to a seal ring () held in non-rotatable manner on the driver device. The driver device () is divided in at least a single radial plane so as to form sections in the form of segments of a circle that are adapted to be clamped together to form a ring shape and furthermore, it is axially sub-divided into a divided retaining ring () for retaining the seal ring () and a divided mounting ring () for non-rotatable mounting to the rotary component. The rings () are coupled together for rotation in common, as indicted by (). The retaining ring () comprises mutually sealed sections () in the form of segments of a circle which are adapted to be placed together to form a ring shape having an inner radial dimension that is greater than the nominal outer radial dimension of the rotary component concerned (), and said sections comprise peripherally aligned end faces () which are preferably in metal-to-metal contact with one another and have a surface finish for mutually sealing them.
