Example Embodiment
[0065] The present invention will be further described below with reference to the drawings and specific embodiments, but the protection scope of the present invention is not limited to this.
[0066] figure 1 , figure 2 versus image 3 Together, the impeller hydraulic design scheme of this embodiment is determined. Two sets of blades are arranged in the flow channel of the submersible pump impeller, and each set of blades is periodically arranged in the circumferential direction. The first set of blades are arranged in the front half of the impeller flow channel, and the second set of blades are arranged in the rear half of the impeller flow channel.
[0067] In the implementation process of the technical solution: the present invention gradually adjusts the geometric parameters of the impeller through the following relational expression, the impeller outlet diameter D 2 , Impeller inlet diameter D s , The width of the impeller outlet b 2 , The first group of blade inlet side L 1...
