摘要:
The invention relates to a turbine motor (1, 50) with a housing (2), forming a duct for a flow of a fluid through the duct (3) in a main flow direction (5) from an inlet (4) to an outlet (6) of the duct (3) and with at least one first and at least one second motor unit (10 and 11), arranged one behind the other in the duct (3) in the main flow direction (5) of the fluid, wherein each of the motor units (10, 11) has a rotor (20) of annular design with an annular inner side (21) and an annular outer side (22) with blades or vanes (23) arranged on the annular inner side (21) of the rotor (20) and the rotors (20) of the motor units (10, 11) are mounted to rotate in the housing (2) in the same and/or the opposite direction, characterised by good efficiency. AAccording to the invention, the above is achieved, wherein the engine units (10, 11) do not have a component running therethrough along the direction of rotation (25) of the rotor (20) thereof and an energising system (26) is arranged on the rotor (20) of the first motor until (10), wherein the first motor unit (10) has a stator (30) arranged annually around the rotor (20) of the first motor until (10), forming an electric motor (40) with the rotor (20) and the energising system (26) arranged thereon and the rotor (20) of the second motor until (11) may rotate independently of the rotor (20) of the first motor unit (10) in order to return an outflow of the fluid caused by the rotor (20) of the first motor unit (10), away from the main flow direction (5) at least partly back into the main flow direction (5).

A pump frame (7) is fixed to a ship bottom (1b) such that an inflow port (19) in a lower portion thereof is open in the water near a stern (1a). A mixed flow pump (8) is fixed to a pedestal (12) provided on the ship bottom (1b). A suction port (26) of the mixed flow pump (8) is connected to a connection port (17) at an upper portion of the pump frame (7), and a discharge pipe (13) is connected to a discharge port (27) of the mixed flow pump (8). Provided in a pump casing (9) of the mixed flow pump (8) is an impeller shaft (33) to extend horizontally, on which is provided an impeller (11) for sucking water below the ship bottom (1b) through the inflow port (19) to pressurize the same. The water pressurized by the impeller (11) is jetted rearwardly of the stem through a discharge pipe (13) whereby a marine vessel (1) is propelled. Such water jet propulsion device (5) provides a suction performance free of cavitation and a high propelling performance.

The invention concerns a ship low-noise hydrojet propeller unit with good performance. It mainly comprises a hydrojet propeller assembly consisting of a hydraulic screw (7) feeding a helico-axial pump (8) emerging in the diffusers (9). A nozzle (10) completes the assembly, which is powered by lateral louvers (6). The electric motor (11R, 11S) is axially represented, but may be radial. The shaft (3) is rotatably mounted, through hydraulic thrust bearings (4V, 4R). The assembly can be have azimuthal orientation. The invention is applicable to ships and submarines.
摘要:
A water jet propulsion unit intended for use in jet boats, the unit comprising an intake section (10), a pump section (12) and a nozzle section (16). In the pump section (12) there are two counter-rotating impellers (14, 15) on concentric counter-rotating shafts (26, 27) calibrated so that any radial flow created in the upstream impeller (14) is converted into axial flow by the downstream impeller (15). In one embodiment the nozzle section (16) has a throttled outlet (17) to allow for a high mass/low pressure operation while maintaining pump priming. There are no support structures or stators downstream of the intake section (10) in the preferred embodiment.

The invention relates to a driving mechanism disposed on the hull (100) of a watercraft comprising an impeller (4) which is used for the propulsion of said watercraft. The impeller is arranged in a housing (1). The cross-section of the flow channel (26) for the impeller is enlarged. Behind the impeller, the cross-section is reduced towards the outlet (6). The cross-section of the outlet can be altered. An adjustable guiding device (2) is arranged in the inlet.
