Advantages and Disadvantages of Hydraulic Control System

Advantages & Disadvantages of Hydraulic Systems.

Hydraulic systems work because of Pascal’s law, which states that an increase of pressure in any part of a confined fluid causes an equal increase of pressure throughout the container. If force is applied to one part of a hydraulic system, it travels through the hydraulic fluid to the rest of the system.


Hydraulic systems allow users to accurately wield large amounts of power with little input force. They also provide constant force, according to the National Fluid Power Association. In addition, hydraulic systems are safe in chemical plants and mines because they do not cause sparks.


Hydraulic systems contain highly pressurized fluid. This can cause burns, bruises or the accidental injection of fluid into the body, according to Colorado State University. Hydraulic systems must be periodically checked for leaks and lubricated, and filters must be changed regularly.
