Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a compressor with a flow guide structure. Background Art

[0002] A compressor is a driven fluid machine that boosts low-pressure gas to high-pressure gas, and the flow guide structure is its core mechanism. Its main function is to guide the fluid into the compressor in a specific way, thereby improving the efficiency and performance of the compressor.

[0003] The core mechanism of the flow-guiding structure is the guide vane, whose primary function is to prevent eddy currents in the fluid at sharp turns, leading to poor airflow, energy loss, and noise. Existing guide vanes are typically fixed at intervals around the circumference of the sleeve. After prolonged flow-guiding operation, the guide vanes may experience a certain degree of wear or corrosion, necessitating the user to replace the entire guide vane and sleeve. This maintenance method is relatively costly, therefore, the present invention aims to provide a compressor with easily removable guide vanes. Utility Model Content
