Hydraulic Systems, How Do They Operate?

How Hydraulic Systems Operate:

To begin, Hydraulic Systems are created by the careful planning, and understanding of numerous parts. These parts that once combined create a hydraulic system can be found bulleted below.


  • Reservoir: The reservoir is crucial to the operation of a hydraulic system. The reservoir holds the Hydraulic fluid needed for the systems operations.

  • Cooler: The is key to the operation of the hydraulic system. without cooling the hydraulic fluid temperatures can rise to a dangerous level that will result in critical failures of components within the system such as, hydraulic hoses, and O-rings
  • Filtration: "Wait? i just bought new hydraulic oil why do i need a filter?" Hydraulic Filtration systems are needed in a hydraulic system because fresh oil often contains up to 10 times more dirt particles then are acceptable for the operation of hydraulic systems. 
  • Hydraulic Pump: now that we have a place to store hydraulic fluid the best way to distribute that fluid to other components of the system is by using a hydraulic pump
  • Electric Motor: There is one use for the motor; that is to supply power to the hydraulic pump, motors can be found in a variety of voltages. The most common motor seen in the field on hydraulic systems operate as a gear motor, vane motor, or piston motor. With the occasional oddball, orbital motors, or gerotor motors
  • Valves: Valves are the regulators of the hydraulic system. The role of the valve is to control the flow of hydraulic fluid and pressures associated with that flow. Valves allow for excessive pressures that could pose risks to the system to be relived. 
  • Hydraulic Cylinders: Finally, Hydraulic Cylinders convert the energy received through hydraulic fluid into back into mechanical energy. The Cylinder is the part of the hydraulic system that moves the bucket, grappler, boom, or lifts

In conclusion,

The hydraulic system uses the pump to transfer hydraulic oil or hydraulic fluid through the system, passing through control and pressure valves and on to the hydraulic cylinder where the hydraulic energy created is turned into mechanical energy to assist you with the task at hand.
There are many different types of hydraulic systems, however, each component listed above is consistent with hydraulic systems across the industry and designed to work in the same way.
