The invention discloses a compressor inlet guide vane structure with a brush seal. The compressor inlet guide vane structure comprises compressor inlet guide vanes and sealing structures, and the compressor inlet guide vanes are provided with the sealing structures. The sealing structures comprise brush wires, fixing rings and fixing plates, the brush wires are arranged in the fixing rings, and the fixing rings are fixed with a casing through the fixing plates. According to the designed compressor inlet guide vane structure, the brush type sealing structures are additionally arranged at the gaps between the guide vanes and the casing, so that the guide vanes control the flow of an inlet more accurately, leakage can be effectively reduced, inlet airflow is more uniform, the influence of leakage flow of the gaps between the tops of the inlet guide vanes on main flow is reduced, the efficiency of a compressor is improved, and the overall efficiency of an engine is improved.
Description
technical field [0001] The invention relates to the field of impeller machinery, in particular to a compressor inlet guide vane structure with brush type seal. Background technique [0002] Various compressors will be subject to changes in climate and working conditions during operation. It is often necessary to adjust the flow rate and intake angle of the gas. A common method of controlling the flow rate is to install guide vanes to adjust the angle before the compressor inlet. However, in the process of operation, the tip clearance of the inlet guide vane will affect the flow field and reduce the efficiency of the compressor. The top gap vortex increases, and the flow loss is serious. Therefore, it is very necessary to improve the tip structure of the inlet guide vane and reduce the tip clearance of the inlet guide vane. Contents of the invention [0003] The invention provides a compressor inlet guide vane structure with a brush type seal to solve the problem that the...
