Centrifugal pump radial sealing ring with cylindrical guide vanes

The invention discloses a centrifugal pump radial sealing ring which is provided with cylindrical guide vanes and mounted at a gap between a volute and an impeller. The centrifugal pump radial sealingring is composed of a disc and the radial guide vanes. The multiple radial guide vanes are evenly arranged on the disc surface of one side of the disc in the circumferential direction. Each radial guide vane is a cylindrical plate. The central axis of each cylindrical plate is perpendicular to the disk surface of the disc. The contour of the radial cross section of each radial guide vane is an arc with any point on an inner ring contour as the circle center and with the radius being R0. The starting point of each arc is located on the inner ring contour of the disc, and the end point of eacharc is located on an outer ring contour of the disc. The centrifugal pump radial sealing ring is a non-contact sealing ring. When a centrifugal pump impeller rotates, rotating liquid generates directional flow under induction
