2) Surface roughness of impeller inlet flow channel
3) The throat area of the blade inlet.
4) The number of blades.
(2) Influence of impeller suction port parameters on cavitation performance of slurry pump
1) The blade inlet angle of attack Δβ is generally a positive angle of attack (3°~10°).
2) The impeller inlet diameter.
3) Width of blade inlet flow channel.
4) Hub diameter.
5) The radius of curvature of the front cover of the impeller.
