| description | The utility model relates to a composite set of shell and impeller is led to modified, including pump shaft, a plurality of shell and a plurality of impeller of leading, lead to be equipped with on the shell and lead the shell runner, the impeller is equipped with the impeller channel, a plurality of shell and a plurality of impellers of leading separate the cooperation suit each other on the pump shaft, the impeller includes integrated into one piece's impeller body and a plurality of blade, lead the installation cavity that is equipped with in the shell with impeller body cooperation installation, the even ring of inner wall of leading the installation cavity of shell is equipped with a plurality of oil grooves, the outer wall that impeller body inserted the end is equipped with the chamfer and forms certain tapering, just outer wall diameter that impeller body is located chamfer department front end is the same with the inner wall diameter size of impeller channel entrance. The utility model discloses it is rational in infrastructure simple, lubricity in the time of can increasing rotating impeller to reduce the impeller and lead the wearing and tearing between the shell, make the flow of liquid more smooth and easy simultaneously, thereby be favorable to improving the pump efficiency. |
