What happens when a hydraulic filter becomes clogged?

[martinwilson]

When a hydraulic filter becomes clogged, it can lead to several serious issues in the hydraulic system:

Reduced Flow Rate: The fluid flow becomes restricted, which can affect the performance of actuators and other components.

Increased Pressure Drop: A clogged filter increases resistance, causing a pressure drop across the filter. This may trigger warning signals or bypass valves.

Bypass Activation (if available): Most systems have a bypass valve that opens to allow unfiltered fluid to circulate, preventing system failure but exposing components to contaminants.

Component Wear: If contaminants bypass the filter, they can cause accelerated wear or damage to pumps, valves, and actuators.

Overheating: Restricted fluid flow can result in poor heat dissipation, leading to overheating of the system.

System Failure: In worst cases, a clogged filter can lead to complete hydraulic failure due to lack of lubrication, pressure loss, or component damage.

Prevention Tip: Regularly inspect and replace filters according to manufacturer guidelines to maintain optimal system health.
