Protective plate for straight pump

The utility model discloses a protection plate for a straight pump, which relates to the field of vertical multi-stage centrifugal pumps and is mounted on a pump head, the protection plate comprises an arc-shaped surface formed by stamping, the radian of the arc-shaped surface is matched with that of the surface of the pump head, two sides of the arc-shaped surface are bent inwards towards the axis O of the protection plate to form folded edges, and the folded edges are bent inwards towards the axis O of the protection plate. The folded edges are completely attached to the surface of the pump head after the protection plate and the pump head are assembled, and the folded edges on the two sides of the arc-shaped face are symmetrical about the axis O; and the joints of the folded edges and the arc-shaped surfaces are in arc transition. The flange and the transition circular arc are added, the stamping forming springback amount and installation stress deformation of the protective cover plate are reduced, the pr
