摘要： Embodiments described herein are generally directed to a venturi valve. The venture valve includes an inlet; an outlet opposite of the inlet; a passage, a primary orifice, and an insert. The passage is positioned between the inlet and the outlet and fluidly coupling the inlet to the outlet. The primary orifice is positioned between the inlet and the outlet and in fluid communication with the passage such that the primary orifice permits fluid to enter the passage. The insert is positioned between the inlet and the outlet, the insert configured to enclose at least a portion of the passage.

摘要： A jet pump slip joint repair assembly includes at least one clamp and a bushing configured to be inserted in a bore of a diffuser and to surround a portion of an inlet mixer. The clamp includes a gripping surface and a gripping collar. The bushing includes a generally cylindrical sidewall, the sidewall configured to surround the portion of the inlet mixer, a grooved flange on an upper surface of the sidewall, at least one cutout between adjacent portions of the grooved flange, and a groove on an inner, bottom surface of the sidewall. The assembly also includes a seal in the groove. The seal is flexible and formed of a metallic material. The seal is configured to be compressed when the at least one clamp engages the bushing.

摘要： A jet pump system and method facilitate the production of a subterranean fluid. The jet pump system comprises a jet pump, a surface pump, a surface pump gauge, and a pump driver coupled to the surface pump to change a drive frequency of the pump driver based on production parameters and pumping parameters of the surface pump (drive frequency (FR) of the surface pump and the power fluid parameters) whereby the surface pump is selectively varied to optimize production. The jet pump method involves deploying the jet pump into the wellbore; pumping power fluid through the jet pump using the surface pump; measuring the pumping parameters; generating the production parameters of the subterranean fluid produced (production rate (QP) of the subterranean fluid); and optimizing the producing by changing the drive frequency (FR) based on the measured power fluid parameters and the generated production parameters.

摘要： An ejector includes a shaft coupled to a passage formation member defining a refrigerant passage inside a body, and the shaft is slidably supported by a support member fixed to the body. A drive mechanism moves the shaft in an axial direction to change a passage sectional area of the refrigerant passage. The passage formation member is provided with a vibration suppressive member including a first mobile end that applies a load to enlarge the refrigerant passage and a second mobile end that applies a load to narrow the refrigerant passage. Both the first mobile end and the second mobile end are disposed on a same side of a slide region of the support member in the axial direction.

摘要： The subject matter of the present invention is a pump arrangement, in particular for use in the body's own vessels, having a pump and a sheath receiving the pump, bounding a flow passage and having a distal intake opening and a proximal outflow opening for producing a driving flow by means of the pump, wherein the pump is arranged in a first fluid-tight section having the distal intake opening and a second fluid-tight section includes the proximal outflow opening. In accordance with the invention, a further inlet opening is present between the first section, and the second section and is arranged between the intake opening and the outflow opening, with the first section and the second section being arranged with respect to one another such that the inlet opening opens into the flow proximal to the pump.

摘要： A system of fuel delivery assemblies is provided. In one example, the system includes two separate fuel pump assemblies each having a reservoir with an interior to receive fuel. Each reservoir has at least one dimension that is different than the other reservoir. A housing is adapted to be separately coupled to each of the reservoirs so that a cartridge may be separately used with both fuel pump assemblies. The cartridge orients at least one fuel system component relative to the reservoir to which the reservoir is connected.
