Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and in particular to an impeller-driven gas compressor. Background Technology

[0002] Centrifugal compressors have advantages such as compact structure, small size, light weight, high single-stage pressure ratio, simple manufacturing process, and wide stable operating range, and are widely used in micro gas turbines and Brayton cycle power generation systems. With technological advancements, the demand for high-performance centrifugal compressors is constantly increasing, especially for special working fluids such as supercritical carbon dioxide, which place increasingly stringent requirements on compressor design. The impeller is one of the most important components of a centrifugal compressor. It is driven by the power of the drive motor to rotate and do work. Due to the inherent design characteristics of the impeller, and the high pressure ratio, high rotor speed, and large centrifugal force of the compressor, air is drawn in. However, in actual use, the air cannot be filtered in time, causing gas dust to enter the interior of the device, reducing the cleanliness of the device. The impeller structure is prone to dust accumulation. Therefore, we have redesigned an impeller-compressed gas compressor. Utility Model Content
