The present invention belongs to the field of
welding processing technology, specifically, a universal
welding tool for centrifugal impellers, including a protective
barrel, the interior of the protective
barrel is provided with
processing equipment, and the exterior of the protective
barrel is provided with a limiting device; the protective barrel includes a pressure-bearing cylinder shell, the front of the inner cavity of the pressure-bearing cylinder shell is fixedly connected with a transparent cover shell, and the inner cavity of the transparent cover shell is evenly provided with
welding equipment. After the
impeller is cooled, a large amount of
moisture will adhere to its outer surface, so the deflection motors on both sides of the device will drive the central
impeller to rotate centrifugally by repeatedly twisting the rotating substrate at
high frequency, thereby throwing off the
moisture attached to the outer surface of the
impeller, and realizing the rapid
drying of the impeller. At this time, the impeller is still in a vacuum environment, so it will not
rust due to oxidation by the air, thereby avoiding the problem of easy
rust on the impeller due to cooling.
