What is a Hydraulic System and its Applications?

What exactly is a hydraulic system? And does every machine really require one?

When you hear the term “hydraulic systems,” you might automatically think of giant machines like cranes or excavators. In reality, however, hydraulics has far broader applications. From agricultural machines, like tractors, to sophisticated mining equipment, hydraulic systems play a crucial role in everyday life.

A hydraulic system provides power to operate a variety of devices, such as elevators and tractor actors. Even though they look complex, these systems are quite simple and require little maintenance. To learn more about what a hydraulic system is and its applications, I suggest you keep reading the rest of the article.

What is a Hydraulic System and its Components?

Hydraulic systems consist of two main parts:

  1. A pump that produces pressurized fluid
  2. A reservoir that stores this fluid

The pump creates pressure by forcing fluid through a series of pipes called hoses. The hydraulic hoses carry the pressurized liquid from the pump to other parts of the system. When the pump stops producing pressure, the hose will collapse and release the stored fluid back into the reservoir.

The reservoir holds the fluid until it is needed again. It can be made up of any number of containers, including tanks, barrels, and even bags.

The full list of components for a hydraulic system:

  • Reservoir
  • Pumps
  • Strainers and filters
  • Valve Types
  • Actuators
  • Motors
  • Accumulators
  • Oil Cooler
  • Cooling Fan
  • Tubing, Piping, and Hose
  • Connectors and fittings
  • Sealing materials and devices

Where is the Hydraulic System used?

There are many different places where a hydraulic system could be used. For example, numerous types of equipment use hydraulic systems for their operation. These include:

  • Elevators
  • Conveyors
  • Pumps
  • Air compressors
  • Lifts
  • Cranes
  • Water treatment plants
  • Oil rigs
  • Construction machinery
  • Mining equipment
  • Industrial robots
  • Automobiles
  • Aircrafts
  • Ships
  • Boats

How Does the Hydraulic System Work?

To understand how a hydraulic system works, let’s take an elevator as an example. An elevator consists of three major components:

1. A motor that drives the cabin

2. A counterweight that balances out the weight of the cabin

3. A cable that connects the cabin to the counterweight

In order to move the cabin up or down, the motor must first turn on. This causes the shaft to rotate, which turns the cable. As the cable rotates, it pulls the counterweight with it. The counterweight then moves upward or downward, depending on whether the motor is turning clockwise or counterclockwise.

In the same way, when the motor shuts off, the shaft stops rotating, and the counterweight falls back toward the bottom of the shaft. Once the counterweight reaches the bottom, the motor starts again, and the process repeats itself.

Imagine if we replaced the motor and counterweight with a hydraulic cylinder. Instead of using electricity, we would use a hydraulic pump to create pressure. We would then connect the hydraulic cylinder to the bottom of the cabin and the top of the counterweight. As the hydraulic cylinder expands and contracts, the cabin moves up and down.

What is a Hydraulic Hose Assemble

A hydraulic hose assembly consists of a hydraulic hose and hydraulic fittings which are crimped on the hose’s two ends. It is a ready-to-use component to replace the broken one. and it is the most important component of the hydraulic system, just like electric wires, they connect all the hydraulic components (Reservoir, Pumps, valves, Actors…) into a closed integration.
