Abstract
The utility model relates to a rotary wheel guide structure of movable propeller turbine, including a runner cone and a handling frame connected with the rotary wheel. The utility model is characterized in that the runner cone is provided with a sliding shaft; the sliding shaft is jacketed with a sliding block; the runner cone is connected with the handling frame through a sliding block and a sliding shaft; the handling frame is a sliding block guide structure distributed with three guide grooves; the handling frame is movably matched with the sliding shaft. The utility model has the advantages of full use of internal space of the rotary wheel, relatively flexible layout, greatly reducing the weight of the rotary wheel and facilitating the processing and casting of the five-blade rotary wheel. In addition, the guide structure can also overcome the large stress on rotating parts caused by the high oil pressure in operation and extend the service life of the impeller. The utility model is simple in structure and easy to process.
Description
Technical field
The utility model belongs to water turbine manufacturing technology field, particularly relates to a kind of simple in structure, movable propeller turbine runner guide structure of being easy to process and save the runner space.
Background technique
At present, relatively Chang Yong movable propeller turbine runner guide structure mainly is made of web and operation stand etc., generally adopt two kinds of forms as the case may be: one, be that feather key is welded on the web, on operation stand, directly process guiding groove, be slidingly matched by guiding groove on the operation stand and the feather key on the web and finish guiding; Its two, be that anti-module is put together on above the operation stand, on web, process guiding groove, directly utilize operation stand to lead.Above-mentioned two kinds of structures all need to rely on web to lead, and therefore require bigger space in bigger web axial dimension and the runner.And that unit is the runner cone part taper ratio of five blades is bigger, and the runner inner space is narrower, adopts above-mentioned guide structure so the problem of runner inner space deficiency occurred.In addition, because the complete symmetry of five blade rotary wheel right and wrong, adopt above-mentioned guide structure bring many troubles also can for the processing casting.
Summary of the invention
The utility model provides a kind of simple in structure, movable propeller turbine runner guide structure of being easy to process and save the runner inner space for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Movable propeller turbine runner guide structure, comprise the draft cone and the operation stand that are connected with web, it is characterized in that: on draft cone, be fixed with the slide block axle, suit slide block on the slide block axle, draft cone is connected with operation stand by slide block, slide block axle, and operation stand and slide block axle are movable fit structure.
The utility model can also adopt following technological scheme:
Described operation stand is a slider guide formula structure, is evenly distributed with three on the operation stand and is convenient to the reciprocating guiding groove of slide block, to realize the guiding purpose of slide block.
Described slide block is the cast copper structure.
Advantage and the good effect that the utlity model has are: because the utility model adopts said structure, not only can make full use of the web inner space, layout is got up flexible relatively, alleviates the weight of web greatly, and is convenient to the processing casting of five blade rotary wheel bodies; In addition, this guide structure also can overcome owing to operation oil pressure height, and causes the stressed bigger problem of each rotating part, and can prolong the working life of impeller.The utility model is simple in structure, be convenient to processing.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model operation stand structural representation.
Among the figure: 1, draft cone; 2, operation stand; 2-1, guiding groove; 3, slide block; 4, slide block axle.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, movable propeller turbine runner guide structure, comprise draft cone 1 and operation stand 2 that web connects, described operation stand is a slider guide formula structure, promptly be evenly distributed with three and be convenient to the reciprocating guiding groove 2-1 of slide block on operation stand, draft cone 1 relevant position is fixed with slide block axle 4 by screw, is set with the slide block 3 of casting in bronze on the slide block axle, draft cone 1 is connected with operation stand 2 by slide block, slide block axle, and operation stand and slide block axle are for movingly.Slide block is reciprocating in the guiding groove of operation stand, realizes the purpose of guiding.Owing to adopt the casting in bronze slide block, and the relative steel of copper material are softer, can play the effect of protection slide block axle 4 to a certain extent.
Working principle of the present utility model is:
On operation stand, be evenly distributed with three guiding grooves, the slide block axle is installed in the draft cone relevant position, with slide block set on the slide block axle, slide block is reciprocating in the guiding groove of operation stand, realize the purpose of guiding, because the slide block axle carries out handle with bolt and draft cone and closes, if targeting part is changed also very convenient because piece takes place to decrease unit generation unusual condition.
Claims (3)
1. movable propeller turbine runner guide structure, comprise the draft cone and the operation stand that are connected with web, it is characterized in that: on the awl of pouring water, be fixed with the slide block axle, suit slide block on the slide block axle, draft cone is connected with operation stand by slide block, slide block axle, and operation stand and slide block axle are movable fit structure.
2. movable propeller turbine runner guide structure according to claim 1 is characterized in that: described operation stand is a slider guide formula structure, is evenly distributed with three on the operation stand and is convenient to the reciprocating guiding groove of slide block.
