BAFFLE PLATE

BAFFLE PLATE 5541 9688 00 Located inside a hydraulic reservoir or air/oil separator tank, this plate's primary function is to direct the flow of fluid. It stops return-line oil from churning the main volume of fluid and minimizes sloshing as the machine moves. This simple action is crucial for preventing air from mixing with the hydraulic oil, a condition known as aeration.

A properly secured baffle plate directly impacts system reliability and performance. By helping to provide a solid, air-free stream of oil to the pumps, it protects them from cavitation damage and helps maintain steady operating pressures. This ensures that drilling functions like feed and rotation remain smooth and predictable, which is vital for both productivity and safe operation.

Failure is often diagnosed through secondary symptoms. If you notice foamy oil in the sight glass, a whining hydraulic pump, or unusually high system temperatures, a dislodged or broken baffle could be the cause. Replacement is typically performed when the tank is drained for major service or cleaning. Ensure it is securely fastened to prevent it from coming loose and causing further damage.
