What is the primary reason for ensuring correct function of air breathers in a reservoir?

The primary reason for ensuring the correct function of air breathers in a reservoir is to prevent pressure fluctuations. Air breathers play a crucial role in maintaining the balance of pressure within the reservoir as the fluid inside expands and contracts due to temperature changes or volume fluctuations. When the reservoir is filled or emptied, air must be able to enter or exit freely to equalize the pressure, thus preventing the creation of a vacuum or excessive pressure that could lead to structural damage or system failure.

Furthermore, proper functioning of air breathers helps to avoid the formation of air pockets that can affect the fluid's movement and performance. While other factors, such as temperature control, fluid expansion, and cleanliness, are essential for the overall efficiency and longevity of the hydraulic system, they are not the primary role of air breathers in this context. The main focus is on managing pressure to ensure safe and effective operation of the reservoir.
