Abstract
The utility model relates to a runner cone of a water turbine. The right end of a rotating wheel of the water turbine is connected with a main shaft, water drainage holes are formed in the rotating wheel of the water turbine, the runner cone is connected with the main shaft through a bolt, and the right end of the runner cone is connected with the rotating wheel of the water turbine. The runner cone of the water turbine is unique in structure and has functions of guiding stream, pressing the rotating wheel tightly and draining water.
Description
Technical field
The utility model relates to a kind of water turbine draft cone.
Background technique
At present, the ratio of some turbine runner blade and crown intersection point diameter D4 and runner nominal diameter D1 is larger, when the bleeding hole in rotation wheel waterexit end arranges routinely, must be in the middle of runner channel, has a strong impact on the hydraulic performance of runner and the drainage performance of spilled water hole.
Summary of the invention
It is unique that the purpose of this utility model is to provide a kind of structure, has the water turbine draft cone of water conservancy diversion, compression runner and drainage.
The technical solution of the utility model is achieved in that a kind of water turbine draft cone, and the right-hand member of rotary wheel of water turbine is connected with main shaft, is provided with spilled water hole on rotary wheel of water turbine, and draft cone is connected with main shaft by bolt, and the right-hand member of draft cone is connected with rotary wheel of water turbine.
The utility model has the advantages that: structure is unique, has water conservancy diversion, compresses runner and drainage.
