Abstract

The intermediate distribution ring will find application in power-plants. The problem is solved of the exact installation of the intermediate distribution ring and the stability of the active body flow volume. The assembly is facilitated, the degree of labour-consumption is reduced and so are the production costs. The intermediate distribution ring for turbine wheels consists of a halved ring (1), which is provided throughout its circumference with a through blade profile (2).

Description

ОБЛАСТ НА ТЕХНИКАТАTECHNICAL FIELD

Изобретението се отнася до междинен разпределителен пръстен за турбинни колела, намиращ приложение в електрически централи.The invention relates to an intermediate turbine wheel distribution ring for use in power plants.

ПРЕДШЕСТВАЩО СЪСТОЯНИЕ НА ТЕХНИКАТАBACKGROUND OF THE INVENTION

Известно е досега, че междинните лопатки се произвеждат поотделно и се монтират на отделно звено.It is known so far that the intermediate blades are manufactured individually and mounted on a separate unit.

Значителен недостатък на тази секционна съставна ситема се състои се в това, че монтажът не е точен и обемът на потока от активно тяло не е устойчив. Монтажът е свързан с голяма трудоемкост и производството изисква специални машини за изработване на отделните части. Накрая, без това да е маловажно, производствените разходи са високи, така че, крайната цена на оборудването е твърде висока.A significant disadvantage of this sectional component system is that the assembly is not accurate and the volume of flow from the active body is not stable. The installation is very labor intensive and the production requires special machines for making the individual parts. Last but not least, production costs are high, so the final cost of the equipment is too high.

ТЕХНИЧЕСКА СЪЩНОСТ НА ИЗОБРЕТЕНИЕТОSUMMARY OF THE INVENTION

Техническият проблем, който трябва да се реши е да се създаде междинен разпределителен пръстен, при който монтажът да е точен и обемът на потока от активно тяло да е устойчив. Монтажът да е облекчен с намалена трудоемкост, а производствените разходи да са намалени.The technical problem to be solved is to create an intermediate distribution ring, in which the mounting is accurate and the volume of flow of the active body is stable. Installation should be less labor intensive and production costs reduced.

Този технически проблем е решен посредством междинен разпределителен пръстен, съгласно това изобретение, имащ следната същност: той се състои от разполовен пръстен, осигурен по цялата си обиколка с проходен лопатъчен профил.This technical problem is solved by an intermediate distribution ring according to this invention having the following essence: it consists of a split ring provided along its entire circumference by a passable blade profile.

Междинният разпределителен пръстен, конструиран съгласно това изобретение има предимствата, че дава възможност пръстенът да се монтира с висока точност на потока от активно тяло, без никаква възможност за флуктуация на потока. Трудоемкостта изисквана за съставяне на целия пръстен по време на монтаж се намалява няколко пъти, като многократно се намаляват разходите за монтаж.The intermediate distribution ring constructed in accordance with this invention has the advantage that it enables the ring to be mounted with high precision of the flow of the active body without any possibility of fluctuation of the flow. The complexity required to assemble the entire ring during assembly is reduced several times, reducing installation costs many times over.

ПРИМЕРИ ЗА ИЗПЪЛНЕНИЕ НА ИЗОБРЕТЕНИЕТОEXAMPLES FOR THE IMPLEMENTATION OF THE INVENTION

Междинният разпределителен пръстен, съгласно Фиг. 1, се състои от разполовения пръстен 1, имащ около своята обиколка проходен лопатъчен профил 2.The intermediate distribution ring according to FIG. 1, consists of a split ring 1 having a perforated blade profile 2 about its circumference.

ИНДУСТРИАЛНА ПРИЛОЖИМОСТINDUSTRIAL APPLICABILITY

Междинният разпределителен пръстен, съгласно изобретението, е предназначен за турбини за парни централи, но може да се използва за всякакви задвижващи работни тела, където се изисква висока точност на дозиране на работното тяло.The intermediate distribution ring according to the invention is intended for steam turbines, but can be used for any actuators where high dosing accuracy of the working fluid is required.
