Abstract: Eine Dichtungsanordnung (40) für eine Turbomaschine enthält mehrere nachgiebige Plattenglieder (42), die an einer Innenfläche eines stationären Gehäuses (18) befestigt sind. Die nachgiebigen Plattenglieder (42) bilden einen Dichtungsring zwischen dem stationären Gehäuse (18) und einem Laufrad (20). Jedes der nachgiebigen Plattenglieder (42) weist wenigstens einen Schlitz (74) darin auf. Die Dichtungsanordnung (40) weist ferner mindestens einen gekrümmten statischen Ring (72) auf, der an der Innenfläche des stationären Gehäuses (18) befestigt ist und der sich radial in den wenigstens einen Schlitz (74) in den nachgiebigen Plattengliedern (42) erstreckt. Der mindestens eine bzw. die mehreren statischen Ringe (72) erstrecken sich in Umfangsrichtung durch und zwischen mehreren der nachgiebigen Plattenglieder (42). Zuletzt enthält die Dichtungsanordnung (40) einen Schwingungsdämpfer (118), der benachbart zu den mehreren nachgiebigen Plattengliedern (42) angeordnet oder darauf vorgesehen ist. Der Schwingungsdämpfer (118) ist dazu eingerichtet, Schwingungen der mehreren nachgiebigen Plattenglieder (42) zu dämpfen.

Abstract: A pump system includes inlet chambers, an outlet chamber, and rotors disposed inside the inlet chambers and the outlet chamber to pump a process fluid from the inlet chambers to the outlet chamber and to direct the process fluid to a separator. A gear chamber is configured to receive a portion of the process fluid from the separator. First and second sets of pump bearings are coupled to the rotors and lubricated by the portion of the process fluid flowing from the gear chamber. A conduit is configured to direct the portion of the process fluid from the pump bearings back to the gear chamber. Some of the portion of the process fluid lubricating the pump bearings is permitted to leak to the inlet chambers. Additional process fluid is continually added to the portion of the process fluid to compensate for fluid leaking to the inlet chambers.

Abstract: In a pump system, a process fluid is directed into inlet chambers of a pump casing at an inlet pressure, and a plurality of rotors disposed inside the pump casing are rotated to pump the process fluid from the inlet chambers to an outlet chamber located between the inlet chambers, wherein the process fluid in the outlet chambers is at an outlet pressure. The process fluid is directed from the outlet chamber to a separator configured to separate particulate matter from the process fluid, and a portion of separated process fluid is directed from the separator to a gear chamber of the pump. Pump bearings are lubricated with the portion of separated process fluid from the gear chamber. Some of the portion of the separated process fluid from the pump bearing is leaked to the inlet chambers via rotor shrouds to reduce accumulation of particulate matter in the inlet chambers. A Pump system and a method for operating a pump system are disclosed.

Abstract: A method of applying a profiled abradable coating onto a substrate in which an abradable ceramic coating composition is applied to a metal substrate using one or more coating application techniques to produce a defined ceramic pattern without requiring a separate web or grid to be brazed onto the substrate. The invention is particularly designed to withstand the higher operating temperatures encountered with the stage 1 section of 7FA+e gas turbines to allow for increased coating life without significant deterioration in structural or functional integrity. Typically, the grid pattern coating begins approximately 0.431'' after the leading edge of the shroud, and ends approximately 1.60'' before the trailing edge of the shroud. In the case of diamond-shaped patterns, the grid pattern will be about 0.28'' long and 0.28'' wide, with an overall thickness of about 0.46.'' The coatings thus provide the required levels of abradability and leakage performance and may be applied as a chevron or diamond pattern with the shape oriented such that the diagonals run perpendicular and parallel to the sides of the shroud.
