摘要： A demister for a gearing system includes a main body shaped as a disk having an inner annular rim coupled to an outer annular rim through a first wall and a second wall opposite from the first wall. A central opening is defined by the inner annular rim and extends between and through the first wall and the second wall. The main body is configured to be rotated about a central longitudinal axis to create centrifugal forces that separate oil mist particles from air. At least one fluid passage extends radially between and through the inner annular rim and the outer annular rim. The fluid passage(s) includes a fluid inlet opening in the outer annular rim and a fluid outlet opening in the inner annular rim. The fluid inlet opening is configured to accept incoming air. The fluid outlet opening is configured to discharge filtered air.

摘要： Various example embodiments relate to rotating coalescers. One embodiment includes a housing comprising a first housing section having a blowby gas inlet structured to receive crankcase blowby gases from a crankcase. The housing further comprises an oil outlet. The rotating coalescer includes an endcap and filter media. The filter media is arranged in a cylindrical shape and is coupled to and positioned between the crankcase blowby gases passing through the filter media by coalescing and separating oils and aerosols contained in the crankcase blowby gases. The rotating coalescer includes a hollow shaft extending through the housing and positioned radially inside of the filter media. The hollow shaft forms a blowby gas outlet structured to route filtered crankcase blowby gases out of the housing. The rotating coalescer further includes a drive mechanism operatively coupled to the hollow shaft.

摘要： There is disclosed an air-oil separator for a gas turbine engine. The separator has a first separator section having a first separator rotatably mounted about a rotation axis and having an air-oil mixture inlet and an air-oil mixture outlet; a second separator section having a second separator rotatable about the rotation axis, the second separator having a first air-oil mixture inlet fluidly connected to the air-oil mixture outlet of the first separator, and a second air-oil mixture inlet; and an air outlet. A first flow path extends from the first air-oil mixture inlet to the air outlet through the two separator sections, and a second flow path extends from the second air-oil mixture inlet to the air outlet, solely through the second separator section A method of operating an air-oil separator is also disclosed.

摘要： A marine outboard motor is provided with an internal combustion engine comprising an engine block defining at least one cylinder, an air intake configured to deliver a flow of air to the at least one cylinder, a crankcase in which a crankshaft is mounted for rotation about a crankshaft axis which is substantially vertical when the marine outboard is vertical, and a crankcase ventilation system configured to vent blow-by gases from the crankcase and to supply vented blow-by gases to the air intake. The crankcase ventilation system comprises a lubricant separation chamber for separating lubricant from the blow-by gases. The lubricant separation chamber is defined by the crankcase and extends along the length of the crankcase substantially parallel to the crankshaft axis.

摘要： A rotary separator includes a drum configured to rotate, and a pickup member extending into the drum. The pickup member includes a pickup channel having a first inlet for receiving a liquid, and a pitot channel having a second inlet for receiving the liquid. The liquid exits the drum through the pickup channel in response to a pressure of the liquid being measured through the pitot channel. A valve may be coupled to the pickup channel. A pressure sensor may be coupled to the pitot channel.

摘要： A component for a centrifugal deaerator for removing gas from a turbomachine air/oil mixture includes a structural part configured to delimit a duct for the flow of the air/oil mixture, and includes a circumferential enclosure for the centrifugal separation of the air/oil mixture, an axial inlet for the air/oil mixture, radial oil outlets, and an outlet for oil-free air. The component includes at least one cellular structure configured to filter the oil while allowing the air to pass and occupying at least a space in the duct.

摘要： A rotating coalescer having an ejected coalesced liquid separating device is described. The separating device prevents re-entrainment of liquid into a stream of filtered gas. The rotating coalescer includes a rotating filter element or coalescing cone stack positioned within a rotating coalescer housing. The outer surface of the rotating filter element or the outlet of the coalescing cone stack is displaced from the inner surface of the rotating coalescer housing. The gap between the rotating filter element or the coalescing cone stack and the rotating coalescer housing allows for ejected coalesced liquid, such as oil, to accumulate on the inner surface of the rotating coalescer housing for drainage and allows for filtered gas, such as air, to exit through a clean gas outlet of the rotating coalescer housing.

摘要： A dirt separator for a vacuum cleaner including a chamber having an inlet through which dirt-laden fluid enters the chamber and an outlet through which cleansed fluid exits the chamber; and a disc located at the outlet, the disc being arranged to rotate in a predetermined direction about a rotational axis, and including holes running from an upstream face to a downstream face through which the cleansed fluid passes. When viewed along the radial direction of the disc, the path of each hole through the thickness of the disc defines a centreline, the centreline being inclined such that it is non-perpendicular to the disc. The centreline of each hole is inclined such that it intersects the upstream face of the disc at a point which is behind, in the direction of rotation of the disc, the point at which the centreline intersects the downstream face of the disc.

摘要： The present invention provides a gas-liquid separator with enhanced performance and easy operation, capable of performing gas-liquid separation such as advanced defoaming or degassing, and with a structure that facilitates easy CIP cleaning and disassembly cleaning, allowing it to meet sanitary specifications.This gas-liquid separator for gas-liquid separation performed by centrifugal force of an impeller mounted on a shaft which is supported by a bearing part and rotates in a casing comprises: the axial end of the impeller farther from the bearing part being positioned with clearance from the inner wall of the casing so as to slide on the inner wall of the casing; an exhaust outlet of the casing disposed in a position opposite the sliding impeller part; a vacuum device connected to the exhaust outlet; a discharge impeller part providing discharge force to the passing fluid formed around the axial end of the impeller; a discharge outlet of the casing disposed in a position opposite the discharge impeller part; and a suction inlet of the casing disposed in a position closer to the bearing part than the discharge outlet.
