摘要： A fluid connection for a hydromotive machine or fluid-control valve having a first duct and a second duct. The first duct includes a mid-portion between a first end of the first duct and a second end of the first duct that has a non-circular cross-section. A second end of the first duct is wholly within the second end of the second duct. A first end of the second duct is wholly outside of the first duct.

摘要： The present invention belongs to the technical field of fluid machinery, and proposes a rotating guide vane module for hydraulic working condition adjustment and a method of assembling in a turbopump. The rotating guide vane module comprises a rotating guide vane back cover plate, a rotating guide vane front cover plate, a rotating guide vane drive gear, and rotating guide vanes. Each rotating guide vane is an integrally-formed independent component and comprises a rotating guide vane back seat, a blade, a rotating guide vane front seat, and a shaft. When the rotating guide vane module for hydraulic working condition adjustment of the present invention is used for adjusting the hydraulic working condition, a center gear rotates to drive the rotating guide vane drive gear, and then the rotating guide vanes rotate to change their opening degrees.

摘要： A reversible pump-turbine and also a guide vane for a reversible pump-turbine with a guide vane body, a pivot for rotating the guide vane body around an axis of rotation and two end faces. The guide vane body has a turbine leading edge facing the turbine flow and a turbine trailing edge facing away from the turbine flow, where the individual guide vanes come into contact with one another along closing edges when the wicket gate is closed, where the guide vanes each have two flow-guiding surfaces on either side of the axis of rotation and opposite one another that are limited by the two end faces. These two flow-guiding surfaces have different flow profiles.

摘要： A gravitational vortex water turbine assembly is described wherein the water turbine is disposed below the bottom of the basin in which the vortex is induced. Preferably, the basin comprises a spiral-shaped side wall and the rotor blades of the turbine rotor are dimensioned such that they absorb the tangential, axial and radial component of the water flow of the vortex.

摘要： An axial flow turbine for generating electricity in low-head environments comprises a runner supported by guide vanes that are curved or contoured to direct flowing water onto fixed turbine blades. The axial flow turbine has a housing that provides an outer draft tube. A second inner draft tube is supported within the outer draft. The axial flow turbine may have a bulb or pit-type housing at the intake chamber for housing a direct-drive variable-speed permanent magnet synchronous generator (PMSG) and power converter system. The axial flow turbine may be installed as a single modular unit in low head environments.

摘要： The invention provides a system for the extraction of energy from an underwaterflow stream in a body of water. The system comprises a support frame which comprises a plurality of receptacles for mounting functional modules on the support frame. The plurality of receptacles are arranged to form a horizontally-distributed two-dimensional array on the support frame. The plurality of vertical axis turbine units is configured to be interchangeably mounted in the receptacles.

摘要： An apparatus for modifying the geometry of at least one part of a turbine can include a shell assembly 3 that includes an outer shell that is shaped to modify the shape of a pre-existing element of a turbine. The outer shell 8 of the shell assembly 3 can be composed of a fiber-reinforced polymeric material and can at least partially define an inner cavity. The outer shell 8 can be bonded to a structure to modify the geometrical shape of that structure. Thereafter, a polymer casting 12 can be injected into the inner cavity via at least one injection port attached to the shell assembly. In some embodiments, one or more stiffeners 9 and/or a core 10 can be positioned within the inner cavity to help improve the bonding of the polymer casting 12 to the shell 2 and/or improve a structural property of the apparatus.

摘要： The present invention generally relates to hydraulic machinery, such as hydraulic turbines. More specifically, the invention is directed to optimizing power consumption when the turbine is used in condenser mode. The present invention provides a novel hydraulic installation where the reduction of pressure in the spiral case during condenser mode operations is more efficient, limiting the power consumption if compared to state-of-the-art installations.

摘要： A hand-held turbine cleaning tool includes front and rear housings coupled to each other, an outlet at one end of the tool, and a top of the tool at an opposed end. The outlet is directed in a first direction away from the top. An inlet is disposed between the outlet and the top and is also directed in the first direction. A diverter valve at the inlet is moveable between on and off positions. The on position directs water flowing into the inlet from the inlet, up to the top in a second direction opposite the first direction, and then down to the outlet in the first direction. A turbine at the top has a turbine shaft that extends outside the tool. An abrasive member is connected to the turbine shaft and is configured to rotate when water flows from the inlet to the outlet.
