Abstract: Separator and hydraulic accumulator having such a separator. A separator, in particular for a hydraulic accumulator, such as a bellows accumulator, which is produced by a 3D printing process, consisting of one single diaphragm, which, when viewed in cross section, is deflected in an arcuate shape to form a multitude of bellows pleats at deflection points, which delimit the bellows pleats on the outside and the inside, and in that, to obtain an isotensoid or essentially isotensoid stress profile in the diaphragm, the notional extensions of the diaphragm surfaces adjacent to each deflection point form an acute angle with each other, at least in an initial state.

Abstract: A pumping system deployed in a wellbore has a motor, a pump driven by the motor, and a volumetric compensator connected to the motor to accommodate the expansion and contraction of fluids contained within the motor. The volumetric compensator has a head connected to the motor, a base that includes a fluid exchange port that extends to the wellbore, and a housing extending between the head and the base. The volumetric compensator further includes an inverted bellows assembly contained within the housing. The inverted bellows assembly includes a metal bellows that has an interior, an exterior, a proximal end and a distal end. The interior of the metal bellows is in fluid communication with the wellbore. The inverted bellows assembly may also include one or more guide rings connected to the exterior of the metal bellows. The guide rings are lubricated by the clean motor fluid surrounding the exterior of the metal bellows.

Abstract: A high pressure separator/accumulator that uses dual bellows is provided. The dual bellows are not mechanically linked but rather operationally coupled through a fluid medium. The high pressure separators includes a housing defining a first internal space. The housing is in fluid communication with a first fluid system and a second fluid system. A first bellows is coupled to the interior of the separator and defines a space with a variable volume. The space is in fluid communication with the first fluid system. A second bellows is coupled to the interior of the separator, generally opposed to the first bellows, and defines a space with a variable volume. The space is in fluid communication with the second fluid system. The two fluid systems, however, are isolated from each other by the separator. The housing is charged with a fluid medium that transmits force between the first and second bellows.

Abstract: The invention provides a metal bellows type accumulator having an outer shell provided in its one end with a pressure introducing passage in an opening manner, and a metal bellows repeatedly formed peak portions directed to an outer side in a radial direction and trough portions directed to an inner side, capable of expanding and contracting in an axial direction and separating an inner chamber of the outer shell into a pressure introducing chamber communicated with the pressure introducing passage and a gas chamber charged with cushion gas. A tubular portion is provided at a position where an amplitude of vibration in a radial direction becomes maximum in the metal bellows, has a greater diameter than a maximum diameter portion of each of the peak portions and is in contactable with an inner peripheral surface of the outer shell at a predetermined width in the axial direction.

Abstract: A pressure compensator for a subsea device is provided. The pressure compensator provides pressure balancing between a chamber of the subsea device and the surrounding environment when the subsea device is installed at a subsea location. The pressure compensator includes an intermediate compensation chamber that is provided by a compensator enclosure. The compensator enclosure is sealed against the subsea environment. The compensator enclosure includes a bellows portion that is deformable to change the volume of the intermediate compensation chamber. The pressure compensator further includes a flexible hose disposed inside the intermediate compensation chamber. A volume inside the flexible hose provides a main compensation chamber.

Abstract: A method of shutting down a nuclear reactor may include compressing a scram gas that is in fluid communication with a scram accumulator. The scram accumulator defines a chamber therein and contains bellows within the chamber. The bellows are configured to hold a scram liquid in isolation of the scram gas. The scram gas exerts a compressive force on the bellows in a form of stored energy. The method may additionally include releasing the stored energy in response to a scram signal such that the scram gas expands into the chamber of the scram accumulator to compress the bellows and expel the scram liquid from the scram accumulator to insert control rods into a core of the nuclear reactor.

Abstract: A system for determining the location of a piston within an accumulator is provided in which a short circuit is created between elements in the accumulator and the piston which is movable within the accumulator. As the piston moves along the longitudinal axis of the accumulator, the circuit's electrical characteristics (e.g., voltage, resistance, current) vary in accordance with the length of the circuit. Measurement of these electrical characteristics allows for precise determination of the piston location relative to the accumulator. In a commercial embodiment, the invention can be utilized to determine fluid volumes in an accumulator by monitoring the location of the piston. This invention overcomes prior art systems because, inter alia, it does not require electrical sensory equipment, enables remote monitoring, maintains system integrity and functions irrespective of container wall thickness.

Abstract: A device for fluid power recuperation with reduced heat losses and increased efficiency of fluid power recuperation combined with better manufacturability and possibility of using off-the-shelf gas receivers (bottles). The device comprises at least one hydropneumatic accumulator, containing in its shell a fluid port communicating with the fluid reservoir of the accumulator separated from the gas reservoir of the accumulator by a movable separator. The gas reservoir of the accumulator communicates via a gas port with at least one gas receiver containing a regenerating heat exchanger made in the form of a metal porous structure. The aggregate volume of the material of the regenerating heat exchanger is in the range from 10 to 50% of the internal receiver volume and the aggregate area of the heat exchange surfaces of the regenerating heat exchanger reduced to the aggregate internal receiver volume exceeds 2000 cm2/liter. At gas compression or expansion the heat exchange between the gas and the regenerating heat exchanger occurs at small average distances between the gas and the heat exchange surfaces and on a large heat exchange area, and, therefore, with smaller temperature differentials, which increases reversibility of the heat exchange processes and recuperation efficiency. The proposed device has the following properties:—reduced heat losses and increased efficiency of fluid power recuperation;—better manufacturability;—possibility of using off-the-shelf gas receivers of any type in the device.
