block inserts in the first groove, the end tab position of fixture block snaps in the second groove, realize the clamping between blade and back shroud, described draw-in groove is uniformly distributed around the central axis of back shroud, described front shroud end face is provided with 12 the first through holes, the end face that described blade coordinates with front shroud is provided with axially offers mounting hole along impeller body, described mounting hole comprises a tapped hole and a circular locating openings, described screw thread hole count equals the first via count with location hole count sum, described impeller body also comprises two links, described link is ring, described link and impeller body concentric, described link is provided with the projection matched with the first through hole, described projection matches with positioning hole, described projection inserts positioning hole through the first through hole, described link is also provided with the second through hole and bolt, described second through hole is identical with the first through-hole diameter, described bolt is connected with tapped hole with the second through hole through the first through hole, described projection number and the second via count are the half of the number of blade, described projection and the second through hole are evenly interspersed around the central axis of impeller body, described front shroud is provided with scrobicular ring that is multiple and front shroud concentric, described scrobicular ring matches with link.First blade sliding type is connected on described back shroud, then by bolt, front shroud is connected with blade, limit blade is carried out by the connection of bolt after front shroud and honeycomb duct being connected, and then the slip between limit blade and back shroud, thus realize removably connecting between blade and front shroud and back shroud, when these impeller generation wearing and tearing cannot be used, only need change wearing and tearing and connect, greatly reduce maintenance and the user cost of this impeller.It is low that the utility model has maintenance cost, leakage phenomenon can not occur and be convenient to the features such as mobile.
