The invention relates to a compressor fixed blade ring assembly. The compressor fixed blade ring assembly comprises a pressing ring and a fixed blade ring, wherein the fixed blade ring comprises a protective ring and fixed blades; one end of each fixed blade is fixed to the inner side of the protective ring; the pressing ring and the protective ring are arc-shaped structures; the pressing ring is concentrically arranged on the outer side of the protective ring; first bulges and first grooves which are smoothly connected are alternately formed in the inner surface of the pressing ring; second bulges and second grooves which are smoothly connected are alternately formed in the outer surface of the protective ring; the first bulges and the first grooves correspond to the second bulges and the second grooves one by one respectively. The compressor fixed blade ring assembly provided by the invention solves the problem, in the prior art, that the fixed blade ring is difficult to detach because relatively high friction resistance exists between radial fitting surfaces due to a small clearance between the outer protective ring and a guiding slot of a compressor housing.
Description
technical field [0001] The invention relates to the technical field of compressor manufacturing, in particular to a compressor vane ring assembly. Background technique [0002] A compressor is an impeller device that uses rotating mechanical energy to do work on the air flowing through it to increase the air pressure. A typical compressor for a gas turbine is generally of the multistage axial flow type, with each stage consisting of a row of rotor blades and a row of stator blades. [0003] At present, the stator blade row in the prior art contains dozens of stator blades, such as figure 1 As shown, the end of each vane 72 is fixedly connected to the outer shroud 22 to form an integral vane ring 21 . Wherein, the stator blade ring 21 can be divided into several ring segments in the circumferential direction, and can also be divided into upper and lower half rings. The vane ring 21 is connected with the compressor casing 81 . During installation, the stator blade ring 21 ...
