The Primary Functions of Hydraulic System Components

Blog | October 10th, 2021

To effectively operate and carry out their functions, many equipment pieces and tools now rely on the functions of a hydraulic system. A hydraulic system works by applying pressure to the hydraulic fluid so that a huge amount of energy can be generated to make the previously stated things work.

Manufacturers of equipment pieces and tools rely on hydraulic systems in powering them since they boast a lot of advantages. For one, they are simple to maintain as they only maximise fewer moving components. Hydraulic systems are likewise maximised by manufacturers as they are easy to control and operate. They could even provide constant force or torque regardless of the speed changes. Other advantages of these systems are safer operations, quieter processes, easier maintenance.

All the features and benefits of hydraulic systems are made possible thanks to their accompanying components. Here are some of the system components and their primary functions.


Known as the heart of hydraulic systems, pumps are the ones responsible for the conversion of mechanical energy to hydraulic energy. Pumps can boast numerous configurations, namely, single, double, and triple. They can likewise come in special hybrid piston and vane pumps. Most pumps used in hydraulic systems are power-driven. But for emergencies, hydraulic systems can utilise hand pumps, especially if the power-driven pumps have failed to operate.


Valves are another component of hydraulic systems that are considerably important. By opening and closing accordingly, these components can easily regulate the fluid flow inside the system. They can likewise control the flow of the fluid as well as maintain adequate pressure of the fluid with their primary operations. Three vital types of hydraulic valves that are known in the industry today are directional control valves, pressure control valves, and flow control valves. 


Pumps are known for converting mechanical energy to hydraulic energy. But when it comes to the conversion of hydraulic energy into mechanical energy, the specific component that can carry this function out is the actuator. Actuators or actuating devices can be further divided into cylinders and motors. Cylinders are also called linear motion actuators since they generate a unidirectional force. Motors, on the other hand, can convert hydraulic energy into rotating mechanical energy.


Another significant component of hydraulic systems is the filter. Filters are designed to effectively prevent hydraulic fluid from being contaminated by rust, foreign particles, and other unwanted elements. Filters that are fully maintained can conveniently remove these particles so that the hydraulic fluid will remain clean. Failure to maintain or replace the filters regularly would only result in a decrease in hydraulic fluid pressure and critical damages to hydraulic system components.


Connections or connector products, ultimately, are parts that connect other hydraulic system components. They often interlink pumps, motors, cylinders, and others so that the hydraulic fluid can transfer among these parts. The connector products are designed to be flexible, ensuring that they can be installed inside the hydraulic systems without requiring too much space. Some examples of connector products include hoses, tubes, and pipes.
