Description
Technical field
The utility model relates to axle sealing structure technical field on guide vanes of water turbine, relates in particular to axle on a kind of guide vanes of water turbine that prevents silt erosion, extension device operating life.
Background technique
Because Bulb Turbine Units is that horizontal axis is arranged, stator taper is arranged between inside and outside ring sparger, and stator becomes 60 degree angles with unit centre line.Sealing and O type circle are housed between axle and outer gate barrel on stator.In prior art, on stator, axle coordinates with seal ring that to allow maximal clearance be 0.4mm; Seal ring coordinates permission maximal clearance with outer gate barrel be 0.226mm; Sleeve coordinates permission maximal clearance with outer gate barrel be 0.176mm.When on stator, axle repeatedly rotates or is subject to larger radial force, river will carry silt along axle, seal wears on gap and stator; If seal ring and outer gate barrel gap are less than normal, seal ring cylindrical suffers restraints, and inner circle wearing and tearing are more obvious.On stator, axle, seal wears occur when aging, there will be spilling water situation compared with zanjon grain or O RunddichtringO, by axle, seal ring, sleeve etc. on further corrosion stator, cause more fast water like this.On some stator, axle becomes an integral body with guide vane lever corrosion, and this brings compared with burden to maintenance.In order to take out axle and guide vane lever on the stator of corrosion, once used 100 tons of hydraulic jack, just in conjunction with beaing, the method such as the roasting guide vane lever of fire splits out guide vane lever reluctantly.Therefore, because sealing configuration is bad, cause leaking, axle and guide vane lever on stator are got rusty, will produce expensive, super loaded down with trivial details maintenance problem.
Model utility content
The purpose of this utility model is to provide axle on a kind of guide vanes of water turbine that prevents silt erosion, extension device operating life.
To achieve these goals, the technological scheme that the utility model provides is: axle on a kind of guide vanes of water turbine that prevents silt erosion is provided, comprise: axle and stator on stator, and between axle and described stator, be provided with sleeve and outer gate barrel on described stator, described sleeve is located at axle outer wall on described stator, on described stator, between axle and described outer gate barrel, be also provided with seal ring, described seal ring is fixed by screw pins, between described seal ring and described outer gate barrel, is also provided with wool felt collar.
On described sleeve and described stator, between axle outer wall, be also provided with J RunddichtringO, described sleeve upper end is provided with for accommodating the groove of described J RunddichtringO, and described J RunddichtringO is contained in described groove, and by a pressing plate, carries out pressing and fix.
Described pressing plate is pressed on described groove, and is contained in the lump in described groove with described J RunddichtringO.
On described pressing plate and described J RunddichtringO, all offer through hole, and by countersunk screw, described pressing plate and described J RunddichtringO are fixed on described sleeve.
On described seal ring and described stator, between axle, be provided with O RunddichtringO.
On described seal ring and described stator, between axle, be provided with V-shaped seal ring.
Compared with prior art, the utility model is axle on a kind of guide vanes of water turbine that prevents silt erosion, extension device operating life.
By following description also by reference to the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used for explaining embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view that the utility model prevents an embodiment of axle on the guide vanes of water turbine of silt erosion.
Embodiment
With reference now to accompanying drawing, describe embodiment of the present utility model, in accompanying drawing, similarly element numbers represents similar element.As mentioned above, as shown in Figure 1, axle 100 on the guide vanes of water turbine that prevents silt erosion that the utility model provides, comprise: axle 1 and stator 2 on stator, and on described stator, between axle 1 and described stator 2, be provided with sleeve 3 and outer gate barrel 4, described sleeve 3 is located at axle 1 outer wall on described stator, and between axle 1 outer wall, be also provided with J RunddichtringO 5 on described sleeve 3 and described stator, described sleeve 3 upper ends are provided with for accommodating the groove of described J RunddichtringO 5, described J RunddichtringO 5 is contained in described groove, and by a pressing plate 6, carries out pressing and fix.
Described pressing plate 6 is pressed on described groove, and is contained in the lump in described groove with described J RunddichtringO 5.Being shaped as of described groove is set as the shape of holding J RunddichtringO 5 for coordinating, and top remains for holding the space of described pressing plate 6 in advance.
On described pressing plate 6 and described J RunddichtringO 5, all offer through hole, and by countersunk screw 7, described pressing plate 6 is fixed on described sleeve 3 with described J RunddichtringO 5.Because the upper surface of described pressing plate 6 offers for holding the groove of bolt head, when described countersunk screw 7 is screwed in and on described sleeve 3, described pressing plate 6 is fixed with described J RunddichtringO 5, the top of described countersunk screw 7 and described pressing plate 6 upper surfaces are fair.
On described stator, between axle 1 and described outer gate barrel 4, be also provided with seal ring 8, described seal ring 8 is fixed by screw pins 9.
Between described seal ring 8 and described outer gate barrel 4, be also provided with wool felt collar 10.
On described seal ring 8 and described stator, between axle 1, be provided with O RunddichtringO 11.
On described seal ring 8 and described stator, between axle 1, be provided with V-shaped seal ring 12.
In conjunction with Fig. 1, the utility model prevents axle 100 on the guide vanes of water turbine of silt erosion:
(1) for fear of described seal ring 8 and outer gate barrel 4, occur extruding phenomenon, and allow the monolateral car of seal ring 8 cylindrical remove 1mm, guaranteeing has sufficient gap between seal ring 8 and described outer gate barrel 4.
(2) seal ring 8 cylindricals are offered sealing grain again, on the basis that the close circle 11 of O type circle is set, increase V-shaped seal ring 12, by the effect of double seal circle, eliminate because of bigger than normal the caused adverse consequences in gap.
(3) between described seal ring 8 and described outer gate barrel 4, be also provided with wool felt collar 10, thereby filter silt in river.
(4), seal ring 8 two screw pins 9 of screwing on, when with sleeve 3 assemblings after, can prevent that seal ring 8 from rotating with axle on stator 1.
On stator, axle 1 material is generally ZG270-500, and this material is not corrosion-resistant.For fear of axle 1 on river corrosion stator, the monolateral car of sealing surface cylindrical is gone after 5mm, edge stainless steel sleeve, the material of stainless steel sleeve is ZGOCr18Ni9.Stainless steel sleeve coordinates with seal ring 8.When assembling, must guarantee stainless steel sleeve surface finishment and concentricity.
Sleeve 3 is set up seal groove, and joins draw-bore with seal ring 8.On sleeve 3 and stator, between axle 1, increase J RunddichtringO 5.Make pressing plate 6, fixing with countersunk screw 7 by pressing plate 6; Sleeve 3 and four pin-and-holes of outer gate barrel 4 align reaming, fixing by screw pins 9.
Guide vane lever 13 is about the crack of 2mm along the monolateral cutting width of symmetry plane, two ends welding ear handle 14, by tightening two screws, guarantees axle 1 close contact on guide vane lever 13 and stator.During maintenance, pass through ear handle jackscrew, but a little increases axle 1 gap on guide vane lever 13 and stator, thereby remove comparatively easily guide vane lever 13.
Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
