Why is it important to choose the correct viscosity for hydraulic fluid?

The choice of viscosity for hydraulic fluid is crucial because it directly influences the performance and efficiency of the hydraulic system. Viscosity affects how well the fluid can transmit power through the system, impacting the responsiveness and functionality of hydraulic components such as pumps, valves, and actuators.

If the viscosity is too low, the fluid may not provide adequate lubrication or hydraulic pressure, leading to increased wear and tear on components. Conversely, if the viscosity is too high, it can cause sluggish performance and increased energy consumption due to higher resistance to flow. This can result in overheating and potential system failures. Therefore, selecting the appropriate viscosity ensures optimal operation, extends the service life of components, and enhances overall efficiency within the hydraulic system.
