TURBOMACHINERY COMPONENT, METHOD OF ATTACHING PATCH TO TURBOMACHINERY COMPONENT, AND TURBOMACHINERY INSTALLATION

摘要

FIELD: power industry.;SUBSTANCE: guide blade of a turbomachine comprises a housing having the first end that extends to the second end. One of the said first and second ends comprises a mounting element and a mounting component. Patch is disposed at one of the said first and second ends to form a conjugation area. Said patch comprises an assembly element adapted to ensure alignment with the mounting element, and a mounting portion adapted to ensure alignment with the mounting element. There is a fixing element configured and positioned to ensure interaction with the mounting member and the assembly element for holding the patch relative to the housing along at least two axes without using metallurgical connection in a conjugation area. Also a method of attaching plates to the turbomachine guide blade without welding and a turbomachinery installation are represented.;EFFECT: invention allows to attach a patch for turbomachine guide blade, and in connection with said blade is forms channels for cooling air flow passage.;13 cl, 4 dwg
