MFP Low Pressure lube oil at 12# is supplied to which parts?

The supply of low-pressure lube oil at 12 psi to both turbine and pump bearings is essential for several operational reasons. In systems such as those found in main feedwater auxiliary equipment, lubrication plays a crucial role in ensuring the smooth operation and longevity of various components.

Both turbine and pump bearings require lubrication to reduce friction and wear during their operation. The low-pressure lube oil at 12 psi provides sufficient flow and coverage to maintain a lubricating film between moving parts, thereby preventing metal-to-metal contact which can lead to overheating and premature failure. This is especially important in high-speed rotating equipment like turbines and pumps, where the absence of proper lubrication can result in catastrophic failure.

Additionally, having a common lubrication system for both turbine and pump bearings can streamline maintenance and monitoring processes, allowing for more efficient operation overall. This shared approach enhances reliability, as both components are critical for optimal performance in the system.

Control valves, while also needing lubrication for their actuator mechanisms, typically do not rely on the same low-pressure lube oil system used for turbine and pump bearings; their lubrication needs can often be met differently, making this consideration specific to the bearings of the turbine and pump.
