Title:
ROTARY ELEMENT AND COMPRESSOR DEVICE COMPRISED THEREOF
Document Type and Number:
WIPO Patent Application WO/2014/179115
Kind Code:
A3
Abstract:
This disclosure describes new construction for rotary elements that find use in compressor devices, e.g., centrifugal compressors and blowers. This construction utilizes composite materials (e.g., carbon fiber composites) that require less machine time and reduce the weight of the rotary element, while meeting the operational characteristics of compressor devices for use in a wide range of industrial applications. In one embodiment, the rotary element (100) has a bifurcated material design, which uses a first material (e.g., carbon fiber) to form blades and other features of an impeller and a second material (e.g., metal) to form a sleeve (104) with properties that can securely affix the impeller to a drive shaft (112) of the compressor device (108).
