Final answer:
In a large centrifugal system, the oiling system should consist of at least one oil pump to supply oil to the moving parts of the system.
Step-by-step explanation:
In a large centrifugal system, the oiling system should consist of at least one oil pump to supply oil to the moving parts of the system. The oil pump is responsible for lubricating the bearings and other components to reduce friction and prevent damage.
The oil pump circulates the oil throughout the system, ensuring that all the necessary parts are properly lubricated. Without an oil pump, the moving parts of the centrifugal system would experience excessive friction and wear, leading to potential breakdowns and malfunctions.
Therefore, an oiling system in a large centrifugal system should consist of at least one oil pump.
