Embodiment Construction

[0031] figure 1 Shown is a device 1 according to the invention, which essentially comprises a two-way tubular turbine 2, a pressure chamber 3 on the pressure side, which is located at the inlet of the tubular turbine 2, and a suction duct 4, which is located at the suction side. side, which is also the outlet of the tube turbine 2.

[0032] The pressure chamber 3 has a length that is several times its diameter, the cross section of which is substantially constant along its length, and the cross section of the suction pipe 4 widens towards its free end 5 .

[0033] The tubular turbine 2, the pressure chamber 3 and the suction pipe 4 are connected to each other and are located at their installation positions in such a way that in the case of this embodiment all three are arranged in the same, substantially horizontal direction along their axes. This provides the best possible straight path of the water from the inlet to the pressure chamber 3 and the tube turbine 2 respectively...

Abstract

Apparatus with a water turbine or water pump, especially a tube-type turbine (2) with two or more wheels (25, 26) rotating independently of each other and placed successively in the axial direction, especially with mutually opposite blade slopes. The wheels (25, 26) are each coupled to a generator or motor, which is arranged to be controlled mutually independently in regard to rotational speed and electrical power.

Description

technical field [0001] The invention relates to a device according to the preamble of claim 1 for converting stored potential energy of water into electrical energy or converting electrical energy into potential energy of water. Such a device can also be called a hydraulic machine (hydraulic machine), which can be used both as a water turbine with a generator and as an electric motor with a liquid pump. Background technique [0002] Swiss patent specification 606.793 discloses a device with a tubular turbine or pump comprising an impeller with a substantially horizontal shaft and non-adjustable blades. This hydraulic machine can be used as a turbine to convert the potential energy of stored water into electrical energy, and it can also be used as a pump to convert electrical energy into kinetic energy of water. However, this technical solution is less efficient. [0003] Swiss patent specification 606.801 discloses a similar device with a tubular turbine or pump. However,...
