What is the importance of hydraulic fluid in a hydraulic system?

The importance of hydraulic fluid in a hydraulic system primarily lies in its role in transferring power and lubricating components. Hydraulic systems operate by using the incompressibility of the fluid to transmit force through the system. When force is applied to the hydraulic fluid in one part of the system, it is transferred through the fluid, allowing for the movement and operation of machinery and components, such as cylinders and motors.

In addition to power transmission, hydraulic fluid also plays a crucial role in lubrication. It minimizes friction between moving parts, which is essential for the smooth operation of the system. Proper lubrication reduces wear and tear on components, increases efficiency, and extends the lifespan of the hydraulic system.

While other potential roles for hydraulic fluid, such as cleaning, temperature maintenance, and noise reduction, do exist, they are secondary to its primary functions of power transfer and lubrication.
