Hydraulic turbine

Abstract

The invention belongs to the field of fluid machinery, and particularly relates to a hydraulic turbine in which the direction of a housing outlet and the direction of an impeller outlet are mutually perpendicular. In order to to solve the problem that in a traditional hydraulic turbine in which a housing outlet and an impeller outlet are mutually perpendicular, loss of the hydraulic efficiency is severe when a fluid flows through the part between the impeller outlet and the housing outlet, the invention provides the hydraulic turbine. The provided hydraulic turbine comprises a housing, an impeller and a fluid director, wherein the fluid director is fixedly connected with the housing; a working face of the fluid director corresponds to the outlet end of the impeller in the horizontal direction; and a plurality of fluid guiding blades are uniformly distributed on the working face of the fluid director in the circumferential direction, and a fluid guiding inlet in the center of the fluid director and a fluid guiding outlet at the edge of the fluid director are formed. According to the hydraulic turbine, owing to the fluid guiding action of the fluid guiding blades in the fluid director on the fluid, loss of resistance between the impeller outlet and the housing outlet can be reduced, and the hydraulic efficiency of the hydraulic turbine is improved.

Description

technical field [0001] The invention belongs to the field of fluid machinery, and in particular relates to a hydraulic turbine in which the outlet direction of the shell and the outlet direction of the impeller are perpendicular to each other. Background technique [0002] The hydraulic turbine is a mechanical device that converts the pressure energy in the liquid fluid working medium into mechanical energy. The hydraulic turbine can recover and reuse the liquid residual pressure in the process, and convert it into mechanical energy to drive mechanical equipment to achieve energy saving. A conventional hydraulic turbine mainly includes a housing, an impeller and a main shaft, wherein the impeller is located inside the housing and connected to the main shaft. The energy of the fluid is converted into kinetic energy when it passes through the nozzle in the flow, and then enters the casing through the inlet of the casing and performs work on the blades in the impeller, pushing ...
