Oil head of Kaplan turbine and Kaplan turbine with oil head

Abstract

The invention provides an oil head of a Kaplan turbine and the Kaplan turbine with the oil head. The oil head comprises a movable ring (10) connected with a main shaft (8), a fixed ring (11) rotationally connected with the movable ring (10) through two bearings (13), a first oil pipe (2), a second oil pipe (3), a third oil pipe (4), a first oil cavity, a second oil cavity, a third oil cavity, a first operation oil pipe (7), a second operation oil pipe (6) and a third operation oil pipe (5). The first oil pipe (2), the second oil pipe (3) and the third oil pipe (4) are connected with the fixed ring (11). The first oil cavity, the second oil cavity and the third oil cavity are located between the movable ring (10) and the fixed ring (11) and communicate with the first oil pipe (2), the second oil pipe (3) and the third oil pipe (4) correspondingly. The first operation oil pipe (7), the second operation oil pipe (6) and the third operation oil pipe (5) are located in the movable ring (10) and communicate with the first oil cavity, the second oil cavity and the third oil cavity correspondingly. The first operation oil pipe (7), the second operation oil pipe (6) and the third operation oil pipe (5) communicate with a closing cavity, a pressure keeping cavity and an opening cavity of the oil head correspondingly.

Description

technical field [0001] The invention relates to the technical field of water turbines, in particular to a paddle type water turbine and an oil receiver thereof. Background technique [0002] The oil receiver is an important part of the turbine. It is a conversion device that transmits the oil source through the operating oil pipe through the fixed casing. It is used to continuously inject the high-pressure oil from the governor into the runner through the operating oil pipe. Two chambers of the piston in the assembly. The two cavities of the operating oil pipe return oil to each other, and the pressure oil is used to operate the piston mechanism to adjust the rotation of the blades of the turbine, so as to achieve the purpose of adjusting the load of the unit and starting and stopping. The oil receiver is generally installed on the generator floor, and the guide shoe between the oil receiver body and the operating oil pipe adopts a fixed shoe structure. Since the length of ...
