What is one of the functions of hydraulic fluid related to temperature?

One of the key functions of hydraulic fluid related to temperature is to carry heat away from components. Hydraulic systems often operate under high pressure and can generate significant heat due to the movement of fluid, friction, and the functioning of components like pumps and motors. The hydraulic fluid circulates throughout the system, absorbing heat produced by these operations and dissipating it to maintain an optimal operating temperature.

Maintaining a proper temperature is crucial for the efficient performance of the hydraulic system, as overheating can lead to fluid degradation, reduced lubrication properties, and potential damage to components. By effectively transferring heat away from critical areas, the hydraulic fluid helps ensure the longevity and reliability of the hydraulic machinery.
