摘要: A high pressure pump for use in the injection of liquid chemicals into subsea oil or gas wells, and intended to be positioned in the subsea environment adjacent to the wellhead, comprises a piezoelectric actuator (19) for reciprocating a plunger (22) which acts to compress and expand the effective volume of a pumping chamber (29) having a valved inlet (15) connected to a source of the liquid and a valved outlet (16) to lead the liquid to the well. The device has a minimum of moving parts and in particular avoids the need for any rotating parts and attendant high performance bearings and seals.

摘要: A multistage flextensional transducer includes at least one inner elongate driver member within and mechanically coupled to an inner shell that is nested within an outer shell; the inner shell comprising a pair of contact portions abutting the driver member and a pair of transmission portions on opposite sides of the inner shell between the contact portions; the outer shell being arranged so that the transmission portions act as bridging driver members between the said inner and outer shells, flexure of the outer shell being driven, on actuation of the transducer, by movement of the bridging driver members. The transducer may act as a push or pull actuator or sensor, may magnify displacement and may employ smart materials as driver members. Also cylindrical modules containing thin flextensional actuators may provide axial displacement in a downhole environment and may move a device axially along a downhole pipe or close a valve opening or inch along the pipe.

摘要: A device for the generation of electrical power from a fluid flow, and more particularly for harvesting power from flows downhole in oil or gas wells, comprises a cylinder or other blunt body (1) arranged crosswise to the flow and supported on the end of a sprung cantilever arm (3) held in a fixed mount, with freedom to oscillate in response to the shedding of a Karman vortex trail v from the′ body. The resultant motion of the body (1) and arm (3) is converted into electrical energy by piezoelectric material (5) which is attached to, and stressed by, flexure of the arm. Other arrangements of piezoelectric and inductive power generation from the oscillation of the device are described.
