| description | The utility model discloses a reinforced impeller and a weld seam protection structure thereof. The reinforced impeller comprises an impeller hub and blades arranged on the outer side of the impeller hub, wherein the impeller hub comprises a middle flange, an outer barrel, and support plates arranged between the flange and the barrel; the support plates are arranged in an upper layer and a lower layer; the upper and lower support plates are fixedly connected with the barrel and the flange in a vertical position welding manner, and weld seam protectors are arranged at vertical position welding positions; the impeller hub is connected with the roots of the blades in a full-length welding manner, and vertical position welding seam protectors are arranged at the two ends of a weld seam; reinforced blades are arranged on the surfaces of the blades in an attachment manner. According to the reinforced impeller and the weld seam protection structure thereof, the vertical position welding positions of the support plates and each of the barrel and the flange are covered with plates being the same as parent metal, and are subjected to full-length welding, so that the vertical position welding positions are relatively sealed, contact with a harmful medium in a using environment is reduced, and damage to the vertical position welding positions caused by the harmful medium is further reduced; in addition, by the reinforced blades, the strength of the impeller is strengthened. |
