The function of seal cages, or lantern rings installed in the centrifugal pump stuffing boxes, is to _______________.
AI Explanation
The correct answer is B) distribute the sealing liquid within the stuffing box.
The function of seal cages or lantern rings installed in the centrifugal pump stuffing boxes is to distribute the sealing liquid (such as water or oil) within the stuffing box. This helps to ensure an even and consistent lubrication of the packing material, which is essential for maintaining a proper seal and preventing air from entering along the shaft.
The other answer choices are incorrect because: A) Lubricating the packing is not the primary function of the seal cage, as that is the role of the sealing liquid itself. C) Sealing air from entering along the shaft is the overall purpose of the stuffing box, not the specific function of the seal cage. D) Cooling the shaft is not the role of the seal cage, as that is typically handled by other components or systems.
