WEAR RING AND CENTRIFUGAL PUMP DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a wear ring capable of preventing leak of fluid from a gap between the wear ring and a casing.SOLUTION: A wear ring 1 is mounted in an impeller 33 of a centrifugal pump device 31 and cooperates with a casing 37 of the centrifugal pump device 31 to divide an internal channel into a high pressure section and a low pressure section. The wear ring 1 includes inside thereof an inlet flow channel 3 and outlet flow channel 5 communicating with each for passing-through of fluid. A direction of at least exit portion of the outlet flow channel 5 has a component directing outward in a radial direction.
