Rotor to be used in a centrifugal pump and Method for reconditioning a rotor for a centrifugal Pump

摘要

Rotor to be used in a centrifugal pump, the pump includes a Housing that contains a camera, an entry for the delivery of the material to be pumped Chamber, and an outlet for discharging the material from the Chamber, and the rotor is Mounted inside the Chamber for When in use, its rotation around an Axis of rotation.The rotor comprises a Front, a Back Shroud, Shroud, and multiple Blades or Vanes between the same, and each Blade has a Leading Edge in the entrance area of the rotor and a trailing edge, the front INNER SIDE shroud has a Curve in the entrance area of the Rotor, and the Inner curve has a radius of curvature (RS) ranging between 0.05 and 0.16 of the rotor Outer diameter (D2). The Shroud further includes a Main face and Heel, or internal ear with a Curved Profile with a Peak or Peak area in the Central Axis which extends towards the front Shroud, and there is a transition zone between the main internal Curve face and Heel.FR is the radius of curvature of the transition zone, and the relationship between 0.32 and FR / D2 is 0.65. It also describes other relationships between the various dimensions of the rotor.
