What is the purpose of regulators in a hydraulic system?

The purpose of regulators in a hydraulic system is to manage pump output and maintain system pressure. In hydraulic systems, the regulator ensures that the pressure stays within a specified range, which is crucial for optimal operation and safety of the system. By controlling the fluid flow and pressure output from the pump, regulators help maintain consistent performance and prevent over-pressurization that could lead to system failures or damage.

In contrast, the other options do not align with the primary function of regulators. Increasing fluid temperature does not relate to maintaining system integrity, and filtering the hydraulic fluid is typically the role of filters, not regulators. Enhancing fluid viscosity also does not fall within the scope of what regulators do, as viscosity is a property of the fluid itself, rather than a function performed by the hydraulic system components.
