Abstract
The installation process of the water distributor of the oversize bulb tubular turbine generator set comprises the following steps: preassembling a water distributor; when in formal installation, the guide vane of the water distributor is arranged at a full-closed position; the guide vane shaft is pulled to the outer ring direction of the water distributor along the axial direction of the guide vane shaft, so that the outer end of the guide vane props against the inner wall of the outer ring of the water distributor; a wedge plate is inserted between the inner end surface of the guide vane and the gap of the inner ring wall of the water distributor and is welded and fixed; welding adjacent guide vanes by using a butt strap; the water distributor is integrally hung in the installation position and is fixedly connected with the tubular seat; and after the water distributor is installed in place, the access board is cut off, and the wedge board is detached. The installation process skillfully uses the guide vanes of the water distributor as the supporting pieces to fix the inner ring and the outer ring, so that the inner ring and the outer ring are not deformed, and the installation precision is ensured; in addition, the installation process firstly assembles the water distributor and then hoists the whole water distributor in place, so that the two steps of assembling and field installation of the water distributor are separated, the time consumption of field installation is reduced, and the installation efficiency is greatly improved.
Description
Technical field
The present invention relates to a kind of mounting process of super large type light bulb through-flow type hydro-turbo generator set water guide mechanism, belong to the scaled bulb tubular hydraulic generator technical group field.
Background technology
From world's hydroelectric development trend as can be seen, the importance of low-head hydroelectric plant construction grows stronger day by day, the size of generating set is also developing to large-scale, super-huge direction, and China water power market also from high water head to low-head development, thereby make that the scaled bulb tubular hydraulic generator group has been subjected to academia and industrial circle is paid close attention to widely.
The scaled bulb tubular hydraulic generator group mainly comprises the hydraulic turbine and the generator of a shared main shaft, and generator, parts of bearings are arranged in the light bulb head, and whole unit places runner according to tubular seat and supplemental support level; The hydraulic turbine is formed by imbedding mechanism, distributor, rotation and auxiliary deployment mechanism, and the distributor composition includes interior ring, outer shroud, is installed on the stator between the inner and outer ring.
It is the Bulb Turbine Units of the present single-machine capacity maximum of China that the Guangxi bridge consolidates the power station, belong to the super large type light bulb through-flow type hydro-turbo generating set, the size of its distributor is huge, the inner and outer rings diameter reaches 5276mm, 10790mm respectively, the quality of whole distributor is huge, the inner and outer rings of distributor very easily produces plastic deformation in hoisting process, has reduced installation accuracy, even causes installing failure.
Summary of the invention
Technical problem to be solved by this invention is, overcomes existing distributor mounting method and very easily produces the deficiency of plastic deformation, provides a kind of installation accuracy high installation process of super large type light bulb through-flow type hydro-turbo generator set water guide mechanism.
The technical solution adopted for the present invention to solve the technical problems is as follows: installation process of super large type light bulb through-flow type hydro-turbo generator set water guide mechanism, and its step is as follows:
1), the prepackage distributor, interior ring, outer shroud, stator are assembled into one, and debug;
2), when formally installing, the stator of distributor is placed the complete shut-down position;
3), guide vane teunnion is axially drawn to the outer gate barrel direction along it, make the stator outer end withstand the outer gate barrel inwall;
4), between the gap of stator inner face and distributor internal ring wall, insert wedge, and its welding is fixing;
5), with the adjacent stator of attachment strap welding;
6), distributor integral body is hung in the installation site, the upstream side inner and outer rings of distributor is connected with the inner and outer rings of tubular seat respectively;
7), distributor is in place after, prescind attachment strap, unload wedge.
Beneficial effect of the present invention is as follows: this installation technology dexterously with the stator of distributor as support member, in order to fixing inner and outer ring, make inner and outer ring that deformation not take place, guaranteed installation accuracy; And this installation technology is the assembling distributor earlier, and then whole distributor lifting is put in place, makes the assembling of distributor with the scene two steps are installed and separates, and has reduced field erected consuming timely, has improved installation effectiveness greatly; This installation reliability of technology is high and be easy to realize, good solution the installation question of super large type light bulb through-flow type hydro-turbo generator set water guide mechanism.
Description of drawings
Fig. 1 is a super large type light bulb through-flow type hydro-turbo generator set water guide mechanism master TV structure schematic diagram.
Fig. 2 is a super large type light bulb through-flow type hydro-turbo generator set water guide mechanism side-looking structural representation.
The specific embodiment
With reference to the accompanying drawings and in conjunction with example the present invention is described in further detail.But the invention is not restricted to given example.
As Fig. 1, Fig. 2 is the super large type light bulb through-flow type hydro-turbo generator set water guide mechanism structural representation, and among the figure, 1 is that interior ring, 2 is that outer shroud, 3 is that stator, 4 is that wedge, 5 is attachment strap.
Installation process of super large type light bulb through-flow type hydro-turbo generator set water guide mechanism of the present invention, its step is as follows:
1), the prepackage distributor, interior ring 1, outer shroud 2, stator 3 are assembled into one, and debug;
2), when formally installing, the stator 3 of distributor is placed the complete shut-down position, stator places the complete shut-down position among Fig. 2, and the stator among Fig. 1 is in fully open position;
3), guide vane teunnion is axially drawn to the outer gate barrel direction along it, make the stator outer end withstand the outer gate barrel inwall, like this, in the present embodiment, draw guide vane teunnion outward by special tool between having stayed and having encircled in stator and the distributor in the gap of stator end, the method of specific implementation has a lot, such as drawing guide vane teunnion outward with suspender, this is common mechanical technique, is not described in detail among the embodiment;
4), between the gap of stator 3 inner faces and distributor internal ring wall, insert wedge 4, and with its welding fixing (wedge 4 and stator 3 welding, wedge 4 and the welding of distributor internal ring wall), guarantee that stator is in the complete shut-down position, and can not become flexible, guaranteed the structural strength of distributor integral body;
5), with the adjacent stator of attachment strap 5 welding, further increase the overall construction intensity of distributor;
6), distributor integral body is hung in the installation site, the upstream side inner and outer rings of distributor is connected with the inner and outer rings of tubular seat respectively;
7), distributor is in place after, prescind attachment strap 5, unload wedge 4, finish to the installation of this distributor.
