Hydraulic cylinders are devices that convert the energy of pressurized hydraulic fluid into mechanical force and motion. BUCKET cylinder assembly supplier give a general overview of how hydraulic cylinders work:
Cylinder tube
The cylinder tube is a long, hollow metal tube that serves as the body of the hydraulic cylinder. It is typically made of steel or other high-strength metals.
Piston
The piston is a cylindrical component that fits inside the cylinder tube and separates the cylinder into two chambers. It is typically made of steel or other high-strength metals.
Piston rod
The piston rod is a long, slender rod that is attached to the piston and extends through a hole in one end of the cylinder tube. It is typically made of steel or other high-strength metals.
Seals
Seals are used to prevent hydraulic fluid from leaking out of the cylinder and to keep dirt and other contaminants from entering. They are typically made of rubber or other elastomeric materials.
Hydraulic fluid
Hydraulic fluid, usually oil or water, is used to fill the cylinder and provide the energy to move the piston and piston rod.
Hydraulic pump
The hydraulic pump is used to pressurize the hydraulic fluid and supply it to the hydraulic cylinder.
When the hydraulic pump pressurizes the hydraulic fluid, it creates a force that pushes against the piston, causing it to move in one direction or the other. As the piston moves, it pushes or pulls the piston rod, which can then be used to generate force and motion in other parts of the system.
