What is the primary function of the reserve tank in a hydraulic system?

The primary function of the reserve tank in a hydraulic system is to store excess hydraulic fluid. In hydraulic systems, the reserve tank, often referred to as an accumulator or a reservoir, ensures that there is an adequate supply of fluid to maintain consistent pressure and function. This allows for fluctuations in fluid volume that may occur due to temperature changes or operational demands.

Having a reserve tank can help accommodate expansions when the fluid heats up and also provides a source to draw from during operations, ensuring that the hydraulic components can operate smoothly without running dry, which could lead to system failure.

While cooling the hydraulic fluid is an important aspect of maintaining system efficiency and preventing overheating, it is not the primary role of the reserve tank. Cooling mechanisms are typically separate components within the system. Similarly, relieving pressure from the filter is important for maintaining system health, but this function does not pertain specifically to the reserve tank, which is focused on fluid storage. Lastly, serving as a manifold for boom rotation pertains to control mechanics rather than the storage function of the reserve tank.
