Abstract:
A method for impelling water in e.g. a lake (2) by with a pump (1) transforming the waves of the lake into whirling water (14) which is sent down towards the bottom (4) of the water area. The pump comprises a horizontally extending whirl pipe (7) with a longitudinal slot (8) and at least one preferably curvedly extending baffle (9) with a top front edge (10a) mainly facing a wave front in the lake in operation and a bottom rear edge (10b) extending along the slot. Both ends of the whirl pipe are fluid-connected to a submersible pipe (16) extending down towards the bottom of the water area. The pump is simple and reliable as it functions without movable parts. The pump can without costs for external energy take surface water high in oxygen and atmospheric air down to enrich "dead" bottom water low in oxygen. At the same time the pump can advantageously be used for removing undesired constituents such as superfluous biomass from the lake and add desired additives such as lime to this.
Abstract:
A water delivery system (18) for delivering water for injection into gas turbine engine combustor (4) includes a centrifugal pump (19) and a metering valve (23). The centrifugal pump (19) has an inlet (20) connected to a water source and a discharge (21) connected to a water supply line (22). The metering valve (23) is connected to the water supply line (22) downstream of the discharge (21) of the centrifugal pump (19). The water supply line (22) is connected to an injector nozzle (14) downstream of the metering valve (23). The metering valve (23) is operable to regulate a flow rate of water in the water supply line (22), to thereby meter an amount of water supplied to the injector nozzle (14).
Abstract:
Die Erfindung betrifft ein Vakuum-Rotorsystem (1) umfassend einen hohlförmigen Rotor (2) mit einer zu beiden Enden (2a, 2b) senkrecht zur Rotationsachse (R) offenen Rotormantelfläche (21) und mindestens zwei innerhalb der Rotormantelfläche (21) mit deren Innenseite (21i) verbundenen Naben (22, 23), die in entsprechenden Lagern (24) zur Rotation des Rotors (2) geeignet gelagert sind, ein den Rotor (2) umschließendes Maschinengehäuse (3) mit mindestens einer Gasauslassöffnung (31) zum Auslassen von Gasen (G) aus dem Maschinengehäuse (3) heraus, ein mit der Gasauslassöffnung (31) verbundenes Vakuumsystem (4) mit mindestens einer Vorpumpe (41) zur Erzeugung eines Vorvakuumdrucks (VD) im Maschinengehäuse (3) sowie mindestens eine im Maschinengehäuse (3) zwischen der Nabe (22) und dem dazugehörigen offenen Ende (2a) der Rotormantelfläche (21 ) in einem geeigneten Abstand (A) zu deren Innenseite berührungsfrei zur Rotormantelfläche (21) zur effektiven Aufnahme von Gas (G) angeordnete und mit der Gasauslassöffnung (31) zur Abfuhr des aufgenommenen Gases (G) verbunden erste Gasentnahmevorrichtung (5, 51) mit einer Gasaufnahmeöffnung (53), die so angeordnet ist, dass der Rotor (2) bei einer Drehfrequenz größer 200Hz selbst einen Teil des sich durch die Rotordrehung entlang der Innenseite (21i) der Rotormantelfläche (21) bewegenden Gasstroms (G) zumindest in die erste Gasentnahmevorrichtung (5, 51) fördert und somit selbst einen Gasdruck im Maschinengehäuse (3) vom Vorvakuumdruck (VD) auf einen geringeren Betriebsvakuumdruck (BD) reduzieren kann.
Abstract:
The invention relates to a method for operating a refrigeration system, in particular an air-conditioning system for motor vehicles, according to which a pressure tube compressor (12) is provided as the compressor. This prevents pulsing in the intake line and the pressurised gas line. The pressure tube compressor (12) achieves an excellent performance even at a minimal mass flow and a high pressure differential and is preferably driven by an electromotor (30). The invention also relates to a refrigeration system equipped with a corresponding pressure tube compressor (12).
Abstract:
Die vorliegende Erfindung betrifft eine Staurohrfördereinrichtung (1), bei der eine einströmende Flüssigkeit (3) in einem Rotor (2) durch Kanäle (4) geführt wird. Die Flüssigkeit (3) wird durch den mit hoher Drehzahl rotierenden Rotor (2) mitgenommen und dadurch entsprechend beschleunigt. Dadurch entstehen starke Fliehkräfte, die zur Trennung der Flüssigkeit (3) in einzelne Phasen (I, II, III) mit jeweils unterschiedlicher Dichte führen. Hierzu hat die Staurohrfördereinrichtung (1) zwei stationäre Staurohre (5), die so ausgeführt sind, dass die jeweiligen Eintrittsöffnungen (6) in unterschiedlichen Abständen gegenüber einer Rotorinnenwandfläche (7) bzw. einer Rotationsachse (8) angeordnet sind.
Abstract:
The present invention relates to a new device for pumping fluid, the pump having chamber which revolves around a central pressure pipe. Other rotating parts of the pump revolve around this same axis such that the pressure pipe functions as the axis of rotation of the device. During the spinning of the chamber and the internal pump elements pressure due to centrifugal forces is formed in the pump house.
Abstract:
An insert (40) is provided for attachment to the inlet or nose of a pitot tube (10) to withstand the wear and damage imposed on the inlet of the pitot tube by high velocity and high pressure fluid moving through the rotary casing and into the pitot tube. The insert (40) reduces the amount of damage normally done to the pitot tube (10) under normal operating conditions thereby extending the life of the pitot tube. When worn or damaged, only the insert needs to be replaced rather than the entire pitot tube as is done in conventional systems. The insert (40) permits the machining of the insert to meet the specifications of a particular application, thereby providing the ability to control pump performance over a wider range of operational conditions.
Abstract:
Die vorliegende Erfindung betrifft eine Staurohrpumpe mit wenigstens einer zuführenden Leitung und wenigstens einer abführenden Leitung sowie einer Hydraulikkammer und einem Antrieb, wobei Antrieb, zuführende Leitung und abführende Leitung auf einer gemeinsamen Seite der Hydraulikkammer angeordnet sind.
Abstract:
The oil pump comprises an open ended conduit (1) extending from a connecting rod journal (3) to below the surface of oil in a crankcase. The conduit is bent and oriented such that the open end (7) is tangential to the radius of crankshaft (5) rotation and faces in the direction of rotation. Channels in the crankshaft and connecting rod journal provide flow paths between the upper end of the conduit and at least one bearing surface.
Abstract:
A lubricating system, preferably for smaller refrigerating machinery of piston compressor type (1, 2, 3) having a substantially vertically extending drive shaft (4). A disc-shaped member (11) is arranged adjacent to the lower part of the drive shaft (4) to be rotated by the rotary movement of the drive shaft (4), arranged having oil transferring means (12; 20, 20', 20'') communicating with oil in an underlying oil reservoir (10). Said oil transferring means (12; 20, 20', 20'') will during a rotary movement transfer oil from the oil reservoir (10) to the upper plane of the disc-shaped member (11), and a tubular pipe (14), having its lower open part (15) open against the rotary direction at the peripheral part of the disc-shaped member (11), moves in the manner of a Pitot pipe pump oil via the tubular pipe (14) from the disc-shaped member (11) for lubrication of the piston compressor (1, 2, 3). The lower portion of the drive shaft (4) can be arranged with a downwardly open conically reduced tubular member (9), which at a high rotary speed collects and transfers oil through a channel taken up in the drive shaft (4) for lubrication of the piston compressor.
