What happens to the oil pressure if the filter becomes clogged?

When a filter becomes clogged, it restricts the flow of oil through the system. As the oil pump works harder to push oil through the blockage, the oil pressure may initially increase due to the increased effort of the pump trying to maintain flow. However, if the clog continues and the flow is severely restricted, it can lead to a drop in pressure eventually.

The correct understanding is that a clogged filter creates elevated resistance to oil flow. This situation prompts the pressure to rise significantly because the pump must exert more force to overcome the obstruction. If the filter has a bypass feature, the system may eventually switch to bypass mode, allowing oil to flow even if the filter is clogged. However, the immediate effect of a clog is a noticeable increase in oil pressure until further restrictions occur.

Recognizing the dynamics of how oil pressure reacts to a clogged filter is crucial for maintenance and troubleshooting in millwright applications. It highlights the importance of regular maintenance to ensure filters are clean and operating effectively to maintain appropriate oil pressure in the system.
