Axial Expansion Self-Compensating Device for Aeroengine Turbine Component Tester

Abstract

The invention belongs to the field of mechanical design, and in particular relates to a self-compensating device for axial expansion of an annular flow path steering component under high temperature and high pressure conditions. Including: the inner steering shell section and the outer steering shell section, the inner steering shell section and the outer steering shell section are ring-shaped structures, one end of the inner steering shell section and the outer steering shell section is connected to the turbine test piece, the inner steering shell section The other end of the outer steering shell section is connected with the exhaust volute or the intake volute; wherein, an annular groove is arranged on the outside of the connection between the inner steering shell section and the outer steering shell section and the connection with the turbine test piece, and the annular groove There is an annular sealing ring in the middle, and an outer pressure ring is arranged outside the inner steering shell section and the outer steering shell section. The outer pressure ring is connected with the inner steering shell section and the outer steering shell section by bolts, and the sealing ring is squeezed by the outer pressure ring. The inner steering shell section and the outer steering shell section are respectively sealed and connected with the turbine test piece. The invention avoids the use of expansion joints, so that the axial length is shorter, and the application environment of the device is greatly expanded.

Description

Technical field [0001] The present invention belongs to the field of mechanical design, specifically relates to a kind of axial expansion self-compensating device for an annular runner steering component that can be used under high temperature and high pressure conditions.
