Abstract
The utility model relates to a tapered water-guiding mechanism of hydraulic turbine, in particular to an internal ring assembly for tapered water-guiding mechanism of hydraulic turbine that only tapered plate needs to be detached so that tapered vanes of hydraulic turbine can be assembled or disassembled conveniently. The utility model aims at the problem that the tapered water-guiding mechanism of the prior hydraulic turbine has complicated structure, large processing amount, and a large amount of time-labor consumption for assembling and disassembling vanes, thereby providing an internal ring assembly of tapered water-guiding mechanism of hydraulic turbine with simple structure, convenient assembly and disassembly for guide vanes, and economy. The utility model adopts technical proposal that: the internal ring assembly for tapered water-guiding mechanism is formed by the following: the tapered plates with the same quantities as the guide vanes are arranged fixedly on the internal ring body by stainless steel bolts, wherein the internal ring body is a basin structure with holes at the middle.
Description
Technical field
The utility model relates to a kind of water turbine Cone Guide Apparatus, particularly a kind of interior ring assembly that needs the dismounting conical plate can conveniently install and remove the water turbine Cone Guide Apparatus of water turbine cone guide vane.
Background technique
The water turbine that flow energy is transformed to mechanical energy is most important and the most general modern a kind of dynamic power machine.Water distributor is the requisite parts of water turbine.Water distributor has multiple structural type, divides various types of water turbine according to natural hydraulic parameters, and the pattern of water distributor and the type of water turbine are complementary.Wherein the water distributor of tubular turbine is a Cone Guide Apparatus.The stator mounting or dismounting of the extraordinary structure of mounting or dismounting of its stator.The cone guide vane assembling and dissembling process is spatial motion.The cone guide vane molded lines is three-dimensional the composition again.And stator that blade profile thicker big for distortion between whole stator inside and outside ring and in rower regulation clearance between guide vanes is the confined space of 1 ‰ guide vane heights be stator can't be changed in place.
The structure of existing Cone Guide Apparatus is by guide vane teunnion center line merogenesis with stator outer shroud or interior ring, the numerous and diverse amount of finish of this structure is big, stator mounting or dismounting trouble, especially in the time of need changing or repair certain stator in the power station, remove the part of removing on all guide vane teunnions of corresponding end, make all stators break away from interior ring or outer shroud, also need remove a lot of correlated parts, take the branch nodal section then apart and could install and remove stator, take apart and also should remove whole runner envelope and right cone pipe in face of the merogenesis for the ring of locating of merogenesis.The Lower Half runner envelope is connected in machine foundation, and is well-known, after the basis is moved and reached the original state that is difficult to recover machine is installed once more, then must influence the installation quality of machine.Take the merogenesis of ring in the merogenesis apart and also should remove whole guide bearing in front, main shaft seal and first half runner envelope, guide bearing can influence the stability of machine run after repeatedly installing and removing.Also there is water leakage phenomenon simultaneously in above structure, and the outer shroud merogenesis produces to leak and can pollute the power station factory building, and interior ring merogenesis produces to leak and can enter oily guide bearing fuel tank and will cause the dangerous operation consequence of unit.Certainly also have inside and outside ring to be overall structure, the power station must be hung in whole stators on the outer shroud when installing, and just there is security hidden trouble in this, and increases the crane gear in power station, and is less economical, poor stability.Reach the runner envelope basis and remove the main shaft seal parts with aforementioned need are moving during the transposing stator, then outer shroud is hung floating back together with 16 or 24 stators and axially moves, the maintainer go into the inherence suspending tens tons even tens of tons of outer shroud inner chamber stator in midair under operation will have the personal safety accident.The safety that guarantees the maintenance man then need be torn after the whole axle system of several meters or tens meters long machine that outer shroud shifted out open and be stood up outward to crouch and put, and gets the dress stator then.Rotation axis system can influence the working life of machine after repeatedly installing and removing, in addition, outer shroud is a kind of shell-slab weldment, lifts together with stator, and outer shroud is yielding, and outer shroud reinstalls the rear guide vane gap and is difficult to guarantee original gap, and the gap increases water leakage and increases thereupon.
Summary of the invention
The utility model is at the existing complex structure of existing water turbine Cone Guide Apparatus, amount of finish is big, and the deficiency that the stator mounting or dismounting are wasted time and energy provides a kind of simple in structure, easy, the economical and practical interior ring assembly that is used for the water turbine Cone Guide Apparatus of mounting or dismounting stator.
The technology that the utility model adopts is finished in the following way: the interior ring assembly of water turbine Cone Guide Apparatus is to form on the ring body in being fixed on by stainless steel bolt by the conical plate with the stator equal number, and wherein interior ring body is middle bathtub construction with holes.
The utility model is compared with existing water turbine Cone Guide Apparatus structure has reasonable in design, the simple characteristics compact, that reduce amount of finish, reduce manufacture cost, simplify procedures of mechanical structure, is a kind of novel interior ring assembly of being convenient to the cone guide vane mounting or dismounting.
Description of drawings
Fig. 1 is the structural representation of the interior ring assembly of water turbine Cone Guide Apparatus.
Embodiment
Contrast accompanying drawing below, the utility model is described in further detail by embodiment.
With reference to accompanying drawing 1, a kind of interior ring assembly of water turbine Cone Guide Apparatus, should interior ring assembly be to form on the ring body 1 in being fixed on by stainless steel bolt 3 by conical plate 2 with the stator equal number, ring body 1 is middle bathtub construction with holes wherein, and stainless steel bolt 3 adopts the M8 stainless steel bolt.Central hole at interior ring body 1 is equipped with guide bearing parts 4.
During use, various foreign material in the river descend with current, and the foreign material of some wood and so on enter between water turbine two stators 6 might damage stator 6.Stator 6 after the damage must be repaired or change, when the needs reparation or when changing certain stator 6, the top runner envelope 9 of dismantling, the correlated parts of main shaft seal parts 5 and this stator 6 big ends, two conical plates 2 about dismounting needs dismounting stator 6 corresponding again are as long as screw off 6 bolts 3 when tearing conical plate 2 open.Be screwed into the screw of 2 M10 again and mention oblique taking-up in the screw on it and get final product.Then on interior ring body 1, promptly there is 15mm deeply for the space of installing and removing stator 6, encircles outside 1 in moving to after stator 6 is rotated in its space.Then stator 6 is tilted, and after the blade profile section placed vertical position, between 8 liang of blades of runner, tiltedly go out again, pack into by the reversal procedure of tearing stator 6 open during dress stator 6, will dismantle part then and reinstall to runner envelope 9 tops.Particularly it is light when power station installation water distributor.Only need interior ring 1, outer shroud 7 difference installation in position with stator 6.Many stators 6 are changed between interior ring 1, outer shroud 7 put in place, at last all conical plates 2 are packed into wherein.Water distributor is installed ready.
