Embodiment Construction
[0020] see Figure 1-2 As shown, the present invention is made up of disc 1 and radial guide vane 2, and the middle of disc 1 has a central through hole. A plurality of radial guide vanes 2 are evenly and fixedly arranged along the circumferential direction on one side of the disc 1 , and the radial guide vanes 2 protrude axially from the disc surface of the disc 1 . Each radial guide vane 2 is a cylindrical plate, and the central axis of the cylindrical plate is perpendicular to the disc surface of the disc 1 . Several countersunk screw holes 3 are processed on the surface of the disc 1 for fixing the disc 1 .
[0021] see Figure 4 and Figure 5 , the present invention is installed between the volute 4 and the impeller 5 of the centrifugal pump. When installing, the central axis of the disc 1 is required to be in line with the central axis of the impeller 5. Fixedly connected to the volute 4, the radial guide vane 2 faces the impeller 5, and the radial guide vane 2 and t...
