HYDRAULIC TURBINE WITH MULTI-LAYERED RUNNER ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2021/029475
Kind Code:
A1
Abstract:
Disclosed in the present invention is a hydraulic turbine comprising: a turbine part equipped with a runner assembly that is rotated by a fluid which is introduced from a high pressure portion on one side and discharged to a low pressure portion on the other side; and a gear part having one end connected to the center of rotation of the runner assembly and the other end having a turbine shaft connected to a generator installed thereon, wherein the runner assembly is formed such that a plurality of runner segments, which have a lobe surface parallel to a rotary shaft having a predetermined thickness, are coupled in a twisted shape at a predetermined angle along the longitudinal direction of the rotary shaft. According to the present invention as described above, since the runner assembly is formed by stacking the plurality of runner segments in a twisted shape along the longitudinal direction of the rotary shaft, the flow of heating water is changed so as to swirl, thereby preventing pulsation from occurring in the wake of the runner assembly.
