description The utility model discloses a steady flow centrifugal impeller capable of reducing inlet backflow. Flow field turbulence can be caused by inlet backflow of the centrifugal impeller. The impeller comprises an inlet channel, a pump shaft, a flow guide metal ring and an impeller body, the pump shaft is sleeved with the inlet channel, and the inlet channel is fixed into an inlet hole of the impeller front cover plate. The flow guide metal ring is integrally in a circular truncated cone shape and is provided with a center hole. The aperture of the central hole is equal to the diameter of the upperbottom surface of the circular truncated cone; a central hole of the flow guide metal ring is fixed with the pump shaft, and the lower bottom surface of the flow guide metal ring is fixed with the impeller rear cover plate; and the height of the flow guide metal ring is equal to that of the blade inlet. The cone-frustum-shaped flow guide metal ring is additionally arranged at the inlet of the impeller to form the flow gui
