What does the baffle in a hydraulic tank do?

The primary function of a baffle in a hydraulic tank is to slow the fluid down as it flows through the tank. This is important for several reasons. When fluid is moving too quickly, it can create turbulence, which may lead to issues such as foaming or contaminant mixing with the fluid. By reducing the speed of the fluid, the baffle helps maintain a more stable environment in the tank, allowing contaminants to settle and providing better separation for the different phases of substances within the tank.

Furthermore, by controlling the flow and turbulence, the baffle can prevent the formation of air bubbles, enhancing the overall performance of the hydraulic system. In this way, the correct choice emphasizes the baffle's role in managing fluid dynamics within the tank, promoting effective operation.
