New space guide blade device used for vertical installation of long-shaft pump

The invention discloses a new space guide blade device used for vertical installation of a long-shaft pump. The new space guide blade device comprises a guide blade outer shell and a guide blade inner shell arranged at the center in the guide blade outer shell. Space guide blade bodies are arranged between the guide blade outer shell and the guide blade inner shell. A guide blade shaft sleeve is arranged at the center of the guide blade inner shell. The guide blade outer shell is a rotator shell. The shell wall of the end, close to an installation flange, of the guide blade outer shell is smooth and recessed inwards, and an annular concave circular arc face is formed. The guide blade inner shell is a rotator shell. The shell wall of the end, close to the guide blade shaft sleeve, of the guide blade inner shell is smooth and recessed inwards, an annular concave circular arc face is formed, and the portion, connected with the guide blade shaft sleeve, of the guide blade inner shell is in smooth transition. The outer diameter of the installation flange is not larger than the maximum outer diameter of the guide blade outer shell. The width of a blade guide-in end is smaller than that of a blade guide-out end. The overall outer diameter of the new space guide blade device is reduced, the original power effect is maintained, and the operation performance of the vertical long-shaft pump is not influenced. The new space guide blade device used for vertical installation of the long-shaft pump is simple and reliable in structure and low in cost, widens the installation range of the long-shaft pump and improves construction efficiency.
