The purpose of this utility model is to avoid above-mentioned deficiency of the prior art and provides a kind of effectively Francis turbine draft cone that carries out the macro-axis sealing to extend tapered sleeve or Taper Pipe.
The purpose of this utility model can reach by following measure: this Francis turbine draft cone extends tapered sleeve or Taper Pipe, have: macro-axis, the runner that connects by key or flange on the macro-axis, the certain diameter place of runner crown has several oblique vents, the lower end of runner crown is connected with draft cone, vent is positioned at the inboard of draft cone, be sleeved on the upper end that top cover on the macro-axis or front shroud are positioned at runner, be set with seal arrangement between macro-axis and top cover or the front shroud, the runner affixed with macro-axis encircles down, the draft tube that foundation ring or back shroud are affixed, its special way is: affixed hollow tapered sleeve or the Taper Pipe that extends to band position, vacuum whirlpool in draft cone bottom, the upper end diameter of hollow tapered sleeve or Taper Pipe is greater than lower end diameter, also can be at the draft cone tail end one section supporting pillar that is connected.
The purpose of this utility model can also reach by following measure: this Francis turbine draft cone extends tapered sleeve or Taper Pipe, have: macro-axis, the runner that connects by key or flange on the macro-axis, the certain diameter place of runner crown has several oblique vents, the affixed draft cone in the lower end of runner crown, vent is positioned at the outside of draft cone, be sleeved on the upper end that top cover on the macro-axis or front shroud are positioned at runner, be set with seal arrangement between macro-axis and top cover or the front shroud, the runner affixed with macro-axis encircles down, the affixed draft tube of foundation ring or back shroud, its special way is: runner crown vent outlet outer end is connected with hollow tapered sleeve or the Taper Pipe that extends to band position, vacuum whirlpool, the upper end diameter of hollow tapered sleeve or Taper Pipe is greater than lower end diameter, also can be at the draft cone tail end one section supporting pillar that is connected.
The purpose of this utility model can also reach by following measure: extending tapered sleeve or Taper Pipe can be made by wear-resisting steel.
The purpose of this utility model can also reach by following measure: extending tapered sleeve or Taper Pipe can be made by abrasive rubber.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the structural representation of Francis turbine when extending tapered sleeve or Taper Pipe and being fixed in the draft cone lower end.
Fig. 2 is the structural representation of Francis turbine when extending tapered sleeve or Taper Pipe and being fixed in runner crown vent outlet outer end.
The utility model is described in further detail below in conjunction with embodiment:
Fig. 1 shows first embodiment of the present utility model.Francis turbine, by macro-axis 1, the runner 2 that connects by flange on the macro-axis 1, the certain diameter place of runner 2 crowns has several oblique vents 3 that is positioned at draft cone 9 inboards, be sleeved on the upper end that top cover on the macro-axis 1 or front shroud 4 are positioned at runner 2, the seal arrangement 5 of suit between macro-axis 1 and top cover or the front shroud 4, encircle 62 times with macro-axis 1 affixed runner, the draft tube 8 that foundation ring or back shroud 7 are affixed, the draft cone 9 that the lower end of runner 2 crowns is affixed, the affixed upper end diameter at band 10 positions, vacuum whirlpool that extends in draft cone 9 bottoms is greater than lower end diameter, form by the hollow Taper Pipe 11 that wear-resisting steel are made.During work, pressure flow enters cavity between runner 2 crowns and top cover or the front shroud 4 from seal ring 12, through vent 3, draft cone 9 and the hollow Taper Pipe 11 that extends, flows into draft tube 8 under the suction of vacuum whirlpool band 10.
Fig. 2 shows second embodiment of the present utility model.Francis turbine, by macro-axis 1, the runner 2 that connects by key on the macro-axis 1, the certain diameter place of runner 2 crowns has several oblique vents 3 that is positioned at draft cone 9 outsides, be sleeved on the upper end that top cover on the macro-axis 1 or front shroud 4 are positioned at runner 2, be set with seal arrangement 5 between macro-axis 1 and top cover or the front shroud 4, encircle 62 times with macro-axis 1 affixed runner, the draft tube 8 that foundation ring or back shroud 7 are affixed, the draft cone 9 that the lower end of runner 2 crowns is affixed, the hollow tapered sleeve 11 that the runner 2 crown vents 3 outlet outer ends 6 affixed upper end diameter that extend to band 10 positions, vacuum whirlpool are made by abrasive rubber greater than lower end diameter, one section supporting pillar 13 composition that place position, hollow tapered sleeve 11 center of circle that draft cone 9 tail ends are connected.During work, pressure flow enters cavity between runner 2 crowns and top cover or the front shroud 4 from seal ring 12, through vent 3, is fixed in the hollow tapered sleeve 11 of extension of vent 3 outer ends, flows into draft tube 8 under the suction of vacuum whirlpool band 10.In the working procedure, the hollow tapered sleeve of being made by the abrasive rubber material 11 begins promptly to be limited on the normal working position through spacing by the supporting pillar 13 at position, hollow tapered sleeve 11 center of circle.
