Patent number: 10617970Abstract: 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.Type: GrantFiled: August 5, 2015Date of Patent: April 14, 2020Assignee: SKF Marine GmbHInventors: Mathias Rusch, Wolfgang Brandt, Nils Boettcher, Carlos Fangauf, Detlef Hammerschmidt, Andreas Konieczny, Christian Preissler, Marko Wrage, Lars Ziemen

Patent number: 10024360Abstract: A thrust bearing configured to support axial loads that act on a rotating body includes a thrust shaft rotatably supportable in a bearing housing, a thrust collar, and a retainer connected to the thrust shaft and configured to support a plurality of thrust pieces. The thrust pieces each have a front sliding surface in sliding contact with the thrust collar, and the retainer includes a disk having a central opening and an outer circumference and a plurality of radial incisions extending radially inwardly from the outer circumference which incisions have inner ends radially spaced from the central opening. The radial incisions define circumferentially adjacent spring sections each of the which is individually axially flexible against and away from the bearing housing to open and close a spring gap between each of the spring sections and the bearing housing.Type: GrantFiled: August 12, 2015Date of Patent: July 17, 2018Assignee: SKF MARINE GmbHInventors: Detlef Hammerschmidt, Mathias Rusch, Marko Wrage

Patent number: 9404582Abstract: 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.Type: GrantFiled: March 15, 2013Date of Patent: August 2, 2016Assignee: Blohm + Voss Industries GmbHInventors: Marko Wrage, Carlos Fangauf

Patent number: 9233745Abstract: A seal apparatus, for sealing around a rotating shaft such as a propeller shaft of a watercraft between the exterior water and an interior lubricant space, includes a multiple seal arrangement with plural seal rings forming seal chambers therebetween, and plural fluid medium lines supplying and/or returning a respective fluid medium to a respective seal chamber. A section of a first medium line is formed as an axial passage through a housing of the apparatus, and a section of a second medium line is formed by a pipe arranged within the axial passage in the housing. A method of making such an apparatus especially by retrofitting an existing seal arrangement involves inserting a pipe into an axial passage in the housing in order to establish two medium lines through the housing where there was previously only one medium line.Type: GrantFiled: May 22, 2014Date of Patent: January 12, 2016Assignee: SKF Blohm + Voss Industries GmbHInventors: Mathias Rusch, Joerg Brand, Marko Wrage, Nils Boettcher

Publication number: 20130313786Abstract: 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.Type: ApplicationFiled: April 13, 2012Publication date: November 28, 2013Applicant: Blohm + Voss Industries GmbHInventors: Carlos Fangauf, Marko Wrage
