水輪機導水機構外環制造技術

本實用新型專利技術涉及水輪機的導水機構，尤其是一種錐形導葉外環。主要針對現有技術中錐形導葉與導水環、轉臂等其他部件連接配合的技術問題，提供一種采用規定尺寸的緊固件作為連接件的導水機構導葉外環。具體技術方案為：錐形導葉的窄端和寬端分別連接導葉內環和導葉外環，導葉寬端的導葉軸上設置導葉套筒，導葉套筒上方設置導葉臂，導葉臂與控制環之間通過連桿連接，其特征在于，導葉套筒套在導葉軸上，其下端與導葉外環的中錐段通過螺釘、螺栓和螺母連接。本實用新型專利技術采用統一規格尺寸的螺栓、螺母、螺釘將錐形導葉、外導水環、套筒、轉臂等連接，避免焊接技術中由人為因素造成的產品技術差異，保證各產品質量統一均衡。（*該技術在2021年保護過期，可自由使用*）

Outer ring of water guide mechanism of hydraulic turbine

The utility model relates to a water guide mechanism of water turbine, especially a conical guide vane outer ring. The main technical problems on the existing technology of conical guide vane and guide ring, rotating arm and other components connected together, provides the specific size of fasteners as the water guiding mechanism of connecting pieces of the guide vane outer ring. The technical scheme is as follows: the narrow end of the conical guide vane and guide vane are respectively connected with the wide end of the inner ring and the outer ring of guide vanes, guide vanes guide Ye Kuanduan arranged on the guide vane sleeve, guide vane sleeve is arranged above the guide vane arm, between the arm and the guide leaf control ring through a connecting rod, which is characterized in that the guide vane sleeve sleeve in the guide vane shaft, cone section and the lower end of the guide vane outer ring by screws, bolts and nuts connecting. The utility model adopts bolt, nut, screw unified size will taper guide, guide ring, sleeve, rotary connection, welding technology products to avoid differences caused by human factors in technology, to ensure the uniform product quality equilibrium.
