Model utility content
The technical problems to be solved in the utility model is, provides a kind of stator mounting structure of axial flow hydraulic turbine, this stator mounting structure, and without the need to pulling down top cover during replacing stator, operation is very easy.
Technical solution of the present utility model is, provides a kind of stator mounting structure with the axial flow hydraulic turbine of following structure, comprises top cover, stator, guide vane teunnion and chassis; Described stator has multiple, and the plurality of stator to be arranged between described top cover and chassis respectively by guide vane teunnion and the plurality of stator is uniformly distributed along described chassis circumference; The two ends of described guide vane teunnion are equipped with outside thread, and described top cover and chassis are equipped with axis hole, and the top of described guide vane teunnion and the bottom axis hole respectively on through described top cover and chassis reveals the outside of putting at top cover and chassis; Top and the bottom of described guide vane teunnion are all combined with nut; The outer side wall of described guide vane teunnion near chassis is provided with the lower limit boss of radial projection; The outer side wall of described guide vane teunnion near top is provided with the reinforcement boss of radial projection; The diameter of described reinforcement boss matches with the aperture of the axis hole on described top cover and the top of this reinforcement boss is contained in the axis hole of described top cover; The diameter of described lower limit boss is not more than the aperture of the axis hole on described top cover.
After adopting above structure, the stator mounting structure of axial flow hydraulic turbine of the present utility model, compared with prior art, has the following advantages:
Because the diameter of reinforcement boss of the guide vane teunnion of the stator mounting structure of axial flow hydraulic turbine of the present utility model matches with the aperture of the axis hole on top cover, the diameter of lower limit boss is not more than the aperture of the axis hole on top cover, like this, when changing stator without the need to dismantling top cover, as long as guide vane teunnion just can be extracted out by the nut laid down on guide vane teunnion top and bottom change stator, operation is very easy, very laborsaving, also greatly can accelerate working efficiency.
Improve as one of the present utility model, the diameter of described lower limit boss and the equal diameters of described reinforcement boss.After adopting this kind of structure, the intensity of described guide vane teunnion is larger.
As another Zhang Gaijin of the present utility model, between the nut on the top of described guide vane teunnion and top cover, be provided with pressing plate.After adopting this kind of structure, described pressing plate can push down top cover, top cover is installed more stable.
