| 摘要 |
A radial bearing assembly for a centrifugal pump can include a first component that has a longitudinal axis and that includes discrete radial surfaces separated by undercuts, the discrete radial surfaces disposed at a radial distance from the longitudinal axis; a second component that has a longitudinal axis and that includes a radial surface disposed at a radial distance from the longitudinal axis; and, formed by concentric alignment of the longitudinal axis of the first component and the longitudinal axis of the second component, a journal and bearing clearance, defined by the difference between the radial distance of the radial surfaces of the first component and the radial distance of the radial surface of the second component, and axially deviant particle passages defined by the undercuts and the radial surface of the second component. Various other apparatuses, systems, methods, etc., are also disclosed.
