Embodiment Construction

[0031] figure 1 Shows a special hydraulic equipment, namely a Kaplan turbine or propeller with adjustable blades. However, the present invention is not limited to its application in this type of fluid machinery, but can be universally applied to various types of hydraulic machinery.

[0032] figure 1 The hydraulic device 10 shown in FIG. 1 includes a fluid channel 12 in which water flows from an upper water level to the upstream end of the device 10 and reaches the discharge zone 16 downstream. The device 10 includes a water turbine 18 having a hub 20 with a longitudinal axis 22 and a plurality of rotor blades 24 adjustable on the hub 20. Each blade 24 can be twisted about a rotation axis 26 that extends substantially perpendicular to the longitudinal axis 22. In this embodiment, the water turbine 18 is shown to be placed vertically. However, the present invention can also be applied to turbines whose longitudinal axis is inclined at an angle with respect to the vertical accor...

Abstract

The invention relates to a method for extending the working area or for increasing the deviation of guided flows, especially in hydraulic dynamical type compressors. The invention is characterized in that the unsteadiness in the flow is increased in order to extend the working area or to increase the deviation in the deviation area.

Description

Technical field [0001] The present invention relates to a method for increasing the working range or increasing the steering of a guided fluid, especially in a hydraulic fluid machine, and a hydraulic machine, especially a turbine having at least one blade for turning a liquid medium on it. The invention also relates to a control or adjustment method for adjusting the working point of a hydraulic machine. technical background [0002] For example, converting fluid energy into electrical energy in a water turbine is an energy technology that does not pollute the environment. It is therefore worth pursuing, for example, to increase the efficiency of such energy production equipment through a working range as large as possible. [0003] The basic structure and working mode of the hydraulic turbine are described in detail in "Dubbel, Mechanical Manufacturing Manual (Springer Publishing House 1995, pages R31-R36)", and its disclosure is fully absorbed in this application. [0004] Fra...
