Abstract: An evaporating system for separating at least two liquids mixed with one another includes a reactor vessel for receiving the mixture from an inlet, the mixture having a mixture level in the reactor vessel, a blowing-in device for blowing a gaseous aerating agent into the mixture and absorbing the first liquid, a heating device for heating the mixture, an outlet for discharging the aerating agent and the absorbed first liquid, and an inlet for introducing a gaseous fluid above the mixture level to generate a gaseous transport stream to the outlet.

Abstract: A seal assembly for sealing a shaft bearing includes a seal housing, first and second seal rings retained by the seal housing, an annular chamber formed between the first and second seal rings and a connecting channel configured to place the annular chamber in fluid communication with a bearing-housing-side oil space. When the seal assembly is installed on a shaft, the connecting channel is configured to permit a fill-level equalization between the oil space and the annular chamber when the oil space is filled to a first possible fill level (N1) and to prevent the fill-level equalization between oil space and annular chamber when the oil space is filled to a second possible fill level (N2).

Abstract: A sealing system for sealing shafts against liquid media, for example propeller shafts, impeller shafts, rudder stocks of ships and the like. Opposing corner regions of the sealing system that are located radially inside of a clamping space, for clamping at least one sealing ring, are formed by inclined run-on surfaces that diverge when viewed radially from the inside towards the outside. For accommodation in the clamping space, a clamping section of the sealing ring comprises two opposite edge regions that are formed by inclined surfaces that correspond to the run-on surfaces.

Abstract: A protective device for a stern tube seal of a propeller-driven vessel, wherein an intermediate space is left open between a stern tube and a propeller hub, which intermediate space is covered by a tubular protective cover concentric with the propeller hub, which protective cover is fixedly anchored to the stern tube and axially overlies the propeller hub leaving an annular gap, wherein a ring concentric with the propeller hub and U-shaped in radial section is disposed inside the protective cover in the intermediate space between the stern tube and the propeller hub, the U-opening of which ring is directed radially outward, and wherein the ring is at least partially formed of a material that has a pourable consistency at 20° C.

Abstract: A seal for sealing around a shaft includes a radially outer clamp-in element to be clamped into a housing, an intermediate membrane part extending radially inwardly (toward the shaft) at an angle from the clamp-in element, and an angled base part at a radially inner end of the intermediate membrane part. A spring is received in a receiving groove that forms a spring pocket in the base part, and the spring exerts a contact pressure of a seal lip of the base part against the shaft. In a pressureless state without a pressure differential across the seal, the spring pocket has a width larger than the sectional diameter of the spring and thus forms a free play space for the spring in the pocket.

Abstract: A seal arrangement for sealing a propeller shaft where it penetrates through the hull of a watercraft includes a shaft bushing around this portion of the shaft, one or more seal rings forming a seal around the shaft bushing, and a stationary support holding the seal ring or rings. The shaft bushing includes an outer bushing part made of a wear-resistant material, arranged coaxially around an inner bushing part made of a material having a high thermal conductivity. The thickness of the outer part relative to the thickness of the inner part is a ratio in a range from 1:10 to 1:3. The two-part shaft bushing can provide optimized thermal conductivity and heat dissipation away from the seal rings to the cool exterior water environment, as well as optimized wear-resistance, corrosion resistance and reduced friction for the seal rings.

Abstract: A seal arrangement for a ship's propeller shaft includes at least one oil-filled seal chamber bounded by seal rings around the shaft, as well as an oil reservoir tank, an oil supply line connecting the tank to the bottom portion of the seal chamber, an oil circulation pump interposed in the supply line between the tank and the seal chamber, and an oil return line communicating from the upper portion of the seal chamber back to the tank. Thereby, oil is continuously circulated through the seal chamber, and thereby flushes out any contaminant particles, air or water that might enter the seal chamber.

Abstract: In seal rings for the sealing of shafts for propeller shafts, impeller shafts, rudder shafts of ships, an arrangement is provided, wherein a clamp-in element in allocated housing-fixed support rings as an installation space is provided with an adjoining intermediate part as a membrane and an angled element facing toward the shaft with formation of a seal lip for contact on the shaft. Thereby the contact region of the seal lip on the shaft is formed by a circle-shaped seal region with a constant radius over the entire adjustment range. Alternatively, the contact region of the seal lip on the shaft is formed by a circle-shaped seal region, whereby in the unloaded condition the seal region in the region facing toward the medium to be sealed comprises a smaller radius relative to a radius in the rearward region of the seal lip.

A nose (13) as a retaining element for the inserted spring is arranged on the membrane as an intermediate part (6) above the spring pocket (11). The membrane is adjustable upon changing a tilt angle (?) by pressure loading up to reaching a limit pressure for contacting on an allocated housing wall (16) such as an extended support ring (5). Thereby an enlarged bottom side contact angle (?) is established in the angled region with the seal lip (2).
