The impeller of the expander is the working wheel of the expander, which is the key component for the working performance of the expander. In addition to high strength, it also requires small gas flow loss. The impeller structure is divided into three types: open impeller, semi-open impeller and closed impeller. The closed impeller has wheel back and wheel cover on both sides. The semi-open impeller has only wheel back and no wheel cover, while the open impeller has neither wheel back nor wheel cover. The open impeller has large leakage loss, and the air separation device is generally not used.
