Apparatus and method for flushing a casting

摘要

An apparatus for flushing a workpiece including a passageway having an inlet and an outlet, the apparatus comprising structure adapted to communicate with the inlet and with the outlet for circulating only a fluid through a fluid flow loop including the workpiece passageway, and structure located downstream of the outlet and upstream of the inlet for removing from the fluid substantially all relatively large particles flushed from the passageway and for allowing relatively small particles flushed from the passageway to remain in the fluid so that the relatively small particles are recirculated through the passageway to act as the sole cleaning medium other than the fluid.
