Abstract

The invention provides a centrifugal compressor and a design method thereof. The centrifugal compressor comprises a front-row centrifugal impeller, a rear-row centrifugal impeller and an axial diffuser, wherein the front-row centrifugal impeller is used for forming an airflow channel to enable airflow to pass and applying work to the airflow through centrifugal force, the rear-row centrifugal impeller is located at an airflow outlet of the front-row centrifugal impeller and used for forming an airflow channel to enable airflow to pass and applying work to the airflow through centrifugal force,and the axial diffuser is located at an airflow outlet of the rear-row centrifugal impeller and used for speed-reducing diffusion of the airflow and enabling the airflow to be changed to the axial direction from the radial direction. The rotating direction of the rear-row centrifugal impeller is opposite to the rotating direction of the front-row centrifugal impeller, so that the front-row centrifugal impeller provides reversed pre-rotation for the rear-row centrifugal impeller. According to the centrifugal compressor, under the condition that the axial size is basically not changed, the rear-row centrifugal impeller replaces a conventional radial diffuser, the double advantages of centrifugal force and high power capacity of reverse pre-rotation are fully utilized, and the purpose that the overall pressure ratio of the centrifugal compressor is greatly improved under the condition of a compact structure is achieved.

Description

Technical field [0001] The present invention relates to the technical field of centrifugal compressors, in particular to a centrifugal compressor. In addition, the present invention also relates to a method for designing a centrifugal compressor. Background technique [0002] In order to further increase the total pressure ratio, the existing centrifugal compressor can increase the tangent speed of the centrifugal impeller outlet on the one hand, but due to material limitations, the tangent speed cannot be increased indefinitely, and the total pressure ratio has limited potential. In addition, high tangent speeds The structural strength and life span of the centrifugal compressor are unfavorable. On the other hand, a multi-stage centrifugal compressor can be used, but the gas compression flow path has a longer stroke and there are large curvature turns between the flow paths. The flow loss is serious, which is not conducive to the efficiency of the centrifugal compressor, and it...
