Abstract

The invention discloses a stator blade installation angle adjusting device and relates to the technical field of gas compressors. The stator blade installation angle adjusting device comprises a stator casing (3), a dividing casing (7), a stator blade (1), a rocker arm (4) and a linkage ring (5). The stator casing (3) is fixedly connected with the dividing casing (7). A first journal is arranged at one end of the stator blade (1). The stator blade (1) is installed on the stator casing (3) through the first journal. One end of the rocker arm (4) is connected with the first journal of the stator blade (1), and the other end of the rocker arm (4) is connected with the linkage ring (5). The linkage ring (5) drives the stator blade (1) to rotate through the rocker arm (4). The stator blade installation angle adjusting device has the beneficial effects that the stator blade installation angle adjusting device can adjust the angle of the stator blade through the linkage ring, the flow of air flowing through each step of a gas compressor is controlled, and stable operation of the gas compressor is guaranteed.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a stator vane installation angle adjustment device. Background technique [0002] Compressor surge is a problem that multi-stage axial flow compressors always have to face, that is, when the engine is working in a non-design state, the flow capacity of the supercharging stage in front of the compressor and the supercharging stage behind the compressor do not match, resulting in front surge and rear vortex or Vortex and pant. In order to ensure the stable operation of the compressor, it is necessary to reasonably control the air flow through each stage of the compressor, and the assembly structure of the reversible guide vane at the inlet of the compressor is usually adopted. Contents of the invention [0003] The purpose of the present invention is to provide a device for adjusting the installation angle of the stator blades, which can reasonably control the air flow throu...
