Abstract

The invention provides a double-stage centrifugal air compressing device. The double-stage centrifugal air compressing device comprises a first-stage centrifugal air compressing device, a second-grade centrifugal air compressing device, a connecting shaft and a reflowing device, wherein the first-stage centrifugal air compressing device comprises a first centrifugal impeller and a first shell; the second-grade centrifugal air compressing device comprises a second centrifugal impeller and a second shell; the connecting shaft is fixedly connected with the first-stage centrifugal air compressing device; the second-grade centrifugal air compressing device is movably connected with the connecting shaft; and the first-stage centrifugal air compressing device is connected with the second-grade centrifugal air compressing device through the flowing device. According to the double-stage centrifugal air compressing device, the first-stage centrifugal air compressing device is connected with the second-grade centrifugal air compressing device through the flowing device, so that the pressurizing ratio of the air compressing device is improved and the oil consumption amount is reduced; and meanwhile, the quantity of parts of the air compressing device is reduced and the manufacturing cost of the air compressing device is reduced.

Description

technical field [0001] The invention relates to the field of compressors, and more specifically, to a two-stage centrifugal compressor. Background technique [0002] In the field of aviation or ground gas turbines, the compressors in the prior art are mainly divided into the following three categories: axial flow compressors, single-stage centrifugal compressors and hybrid compressors. [0003] The axial-flow compressor has the advantages of high boost ratio, high efficiency, large air flow per unit area and low wind resistance, and is mainly used in large and medium-sized thrust engines. The single-stage centrifugal compressor has the advantages of simple structure, reliable operation, wide stable working range and high single-stage boosting ratio, and is mainly used in small power plants and aircraft auxiliary power plants. [0004] The hybrid compressor is a combination of an axial flow compressor and a single-stage centrifugal compressor. It not only embodies the advant...
