Abstract

The design involves a spacer ring, consisting of the halved annulus (1), which has been provided all over its circumference with the through-going blade profile (2).

Description

Technické řešení se týká mezemíkového kruhu pro elektrárenská kola turbín, který nahrazuje skládané statorové rozváděči kolo sestavované z jednotlivých částí.The technical solution relates to an intermediate ring for turbine power wheels, which replaces the pleated stator distributor wheel assembled from individual parts.

Dosavadní stav technikyBACKGROUND OF THE INVENTION

Dosud se mezemíky lopatek vyráběly pro každou lopatku zvlášť a montovaly se v jeden celek. Tento dílčí skladební systém měl velkou nevýhodu v tom, že montáž nebyla přesná, množství průtoku média bylo nestabilní, byla zde velká pracnost při montáži, výroba vyžadovala speciální stroje pro výrobu jednotlivých částí a v neposlední řadě byly vysoké náklady, které zapříčinily, že cena zařízení byla značně vysoká.Until now, the blade interlocks have been manufactured separately for each blade and assembled in one unit. This sub-assembly system had the great disadvantage that the assembly was inaccurate, the flow rate of the medium was unstable, there was a lot of assembly work, the production required special machines for the production of the individual parts and last but not least the high costs was quite high.

Podstata technického řešeníThe essence of the technical solution

Uvedené nedostatky odstraňuje mezerníkový kruh, podle tohoto technického řešení, jehož podstata spočívá v tom, že sestává z půleného mezikruží, které je po celém obvodě opatřeno průchozím lopatkovým profilem.The aforementioned drawbacks are eliminated by the spacer ring according to the present invention, which consists in the fact that it consists of a halved annulus which is provided with a continuous blade profile along its entire circumference.

Mezerníkový kruh podle tohoto technického řešení umožňuje sestavení mezemíkového kruhu s vysokou přesností průtoku média, bez možnosti kolísání množství průtoku. Pracnost při sestavení celého kruhu se při montáži několikanásobně snížila a zároveň se tím mnohonásobně snížily náklady na montáž.The spacer ring according to the present invention allows the assembly of the spacer ring with high media flow accuracy, without the possibility of fluctuating flow rates. The assembly time of the whole ring has been reduced by several times during assembly and at the same time the assembly costs have been reduced many times.

Přehled obrázků na výkreseOverview of the drawings

Technické řešení bude blíže osvětleno pomocí výkresu, na kterém znázorňuje obr. 1 mezemíkový kruh sestávající ze dvou částí v náryse a obr. 2 je řez mezemíkovým kruhem.BRIEF DESCRIPTION OF THE DRAWINGS The technical solution will be explained in more detail by means of the drawing, in which FIG. 1 shows an intermediate ring consisting of two parts in a front view and FIG.

Příklad provedeníExemplary embodiment

Mezerníkový kruh podle obr. 1 sestává z půleného mezikruží I, které je po celém obvodě opatřeno průchozím lopatkovým profilem 2.The spacer ring according to FIG. 1 consists of a split ring I, which is provided with a continuous blade profile 2 over its entire circumference.

Průmyslová využitelnostIndustrial applicability

Mezerníkový kruh podle technického řešení je určen pro parní elektrické turbíny, ale může být použit pro jakákoliv hnací média, kde je vyžadována velká přesnost dávkování média.The space ring according to the invention is designed for steam electric turbines, but can be used for any propellant medium where high accuracy of medium dosing is required.
