Basic structure of hydraulic cylinder

Basic structure of hydraulic cylinder

Hydraulic cylinder as an important actuator in hydraulic system, its basic structure is mainly composed of cylinder, cylinder head, piston, piston rod, sealing device and guide parts.

The cylinder is the main part of the hydraulic cylinder, which is usually a cylindrical cavity for holding the hydraulic oil and piston. The cylinder head is located at both ends of the cylinder and is used to seal the cylinder and connect other components. Piston is the key component in the hydraulic cylinder, it can do reciprocating movement in the cylinder, the hydraulic energy into mechanical energy. The piston rod is connected to the piston and is used to transmit the movement and force of the piston.

The sealing device is an indispensable part of the hydraulic cylinder, which is used to ensure the sealing between the piston and the cylinder and avoid the leakage of hydraulic oil. The guide is used to ensure smooth linear movement of the piston in the cylinder, avoiding bias and stutter.

To sum up, the basic structure of the hydraulic cylinder is compact and complex, and the components cooperate with each other to realize the function of converting hydraulic energy into mechanical energy. Understanding its basic structure helps us to understand and use this important component better.
