Description
Technical field
The utility model relates to sealings in machinery field more particularly to a kind of movable guide vane for pump turbine group
Structure.
Background technique
Pump turbine is the Novel flush accumulation of energy unit occurred the 1930s, with the hydraulic turbine and the concatenated storage of water pump
Energy unit is compared, and weight considerably reduces, and cost reduces, thus is used widely；Pump turbine be broadly divided into mixed-flow,
Diagonal flow type and tubular, it is different to be applicable in head/lift range, pump turbine group, due to axle sealing structure in movable guide vane
Problem, the middle a large amount of leaks of sealing are ineffective although processing is repeatedly.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, it provides a kind of for pump turbine group
Movable guide vane in axle sealing structure, using the sealing structure of the utility model, guide vane teunnion, sealing support ring, top cover lower opening structure
At a seal structures, the twice rubber seal of sealing structure in seal groove, respectively with guide vane teunnion and top cover hole inner headed face
Contact, when assembling in place, rubber seal can generate certain decrement, form sealing leak-stopping, volute pressure water is stopped to leak into
The problem of top cover, the middle sealing of effective solution a large amount of leaks.
A kind of activity for pump turbine group that in order to achieve the above purposes, the technical solution adopted by the utility model is:
Axle sealing structure in guide vane, include movable guide vane axis, sleeve, top cover, movable guide vane, support ring, support ring outer circle sealing ring,
Support ring inner circle sealing ring, sleeve flange；The support ring is hollow circular ring structure, and the structure is by infrastructure ring and top
Side boss ring composition；Circle wall is equipped with interior seal groove on the inside of the support ring, and circle wall is equipped with external seal slot on the outside of support ring, outside
Support ring outer circle sealing ring, support ring inner circle sealing ring are respectively equipped in seal groove and inside and outside seal groove；The support ring top
It is assemblied in sleeve, squeezes into pin, support ring lower part is fixed together with sleeve；The sleeve is hollow cylindrical body, one end
For hatch frame, other end end is equipped with sleeve flange；Movable guide vane axis, the movable guide vane axis and activity are equipped in the sleeve
Guide vane connection；The sleeve is set in top cover hole, and sleeve flange is connected and fixed with pin and top cover end face.
Preferably, the top cover is hollow cylindrical body, top cover inner hole is matched with sleeve outer wall size.
The beneficial effects of the utility model are: using the sealing structure of the utility model, guide vane teunnion, sealing support ring, top
Lid lower opening constitute a seal structures, the twice rubber seal of sealing structure in seal groove, respectively with guide vane teunnion and top cover
Hole inner circle face contact, when assembling in place, rubber seal can generate certain decrement, form sealing leak-stopping, stop spiral case pressure
The problem of power water leaks into top cover, the middle sealing of effective solution a large amount of leaks.
Detailed description of the invention
Attached drawing described herein is to be used to provide a further understanding of the present invention, and constitutes one of the application
Point, but do not constitute the restriction to the utility model.
A kind of movable guide vane axis sealed structural schematic diagram for pump turbine group of Fig. 1.
Wherein: 1 being movable guide vane axis, 2 be sleeve, 3 be top cover, 4 be movable guide vane, 5 be support ring, 6 be outside support ring
