New space guide vane device for vertical installation of suspended semi submersible vertical turbine pump A new space guide vane device for vertical installation of suspended semi submersible vertical turbine pumps, which includes a guide vane outer shell and an inner guide vane inner shell set at the center of the guide vane; There is a space for guide vane blades between the outer shell of the guide vane and the inner shell of the guide vane; The center of the inner shell of the guide vane is equipped with a guide vane shaft sleeve; The outer shell of the guide vane is a rotating body shell, and the shell wall near the installation flange slides inward to form a concave circular arc surface; The inner shell of the guide vane is a rotating body shell, and the shell wall near one end of the guide vane shaft sleeve smoothly concaves inward into a circular concave arc surface, with a smooth transition at the connection with the guide vane shaft sleeve; The outer diameter of the installation flange shall not exceed the maximum outer diameter of the guide vane housing; The width of the blade inlet end is smaller than that of the blade outlet end. It reduces the overall outer diameter, maintains the original power effect, does not affect the operational performance of the vertical suspended semi submersible vertical turbine pump, has a simple and reliable structure, low production cost, improves the installation range of the suspended semi submersible vertical turbine pump, and enhances construction efficiency. Technical requirements: 1. A new space guide vane device for vertically installing suspended semi submersible vertical turbine pumps, comprising a guide vane outer shell (3) and an inner guide vane inner shell (4) set at the center of the guide vane; A space guide vane blade (2) is provided between the outer shell (3) of the guide vane and the inner shell (4) of the guide vane; The center of the inner shell (4) of the guide vane is provided with a guide vane shaft sleeve (6); The spatial guide vane blade (2) comprises a blade inlet end (11) and a blade outlet end (12), characterized in that the guide vane outer shell (3) is a rotating body shell, and the shell wall near the installation flange (5) is smoothly concave inward to form a circular concave arc surface; The inner shell (4) of the guide vane is a rotating body shell, and the shell wall near one end of the guide vane shaft sleeve (6) is smoothly concave inward in a circular arc shape, with a smooth transition at the connection with the guide vane shaft sleeve (6); The outer diameter of the installation flange (5) is not greater than the maximum outer diameter of the guide vane housing (3); The width of the blade inlet end (11) is smaller than that of the blade outlet end (12).
