Embodiment Construction
[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0025] see figure 1 As shown, a three-dimensional flow centrifugal blower with a low-speed multi-stage vertical split cylindrical structure of the present invention is composed of a stator 1, a rotor 2, a bearing 4, a shaft seat 5 and a main shaft 6. The rotor 2 is located in the stator 1, and the two ends of the rotor 2 are respectively fixed by bearings 41, 42, and the two bearings 41, 42 are located in the bearing housings 51, 52.
[0026] In the embodiment of the present invention, the rotor 2 is composed of five stages of independent impellers. The impeller (see figure 2 ), it adopts a closed three-dimensional flow structure, and the blades are three-dimensional streamlined. Based on computational fluid dynamics (CFD) technology, the flow channel of the gas in the blade is optimized to ensure the smooth flow of gas in the impeller. The aerodyna...
