Hydraulic transmission technology is widely used in construction machinery, lifting and transportation machinery, construction machinery, agricultural machinery, automobile industry, mining machinery and metallurgical machinery.
Hydraulic transmission equipment usually consists of four parts: power, execution, control and auxiliary. As a hydraulic mechanism to realize linear reciprocating motion or less than 360 degrees reciprocating motion, the hydraulic cylinder has simple structure and reliable operation, and is widely used in the hydraulic system.

The structure of a hydraulic cylinder is mainly as follows:

CYLINDER BARREL

The cylinder barrel is the main component of the hydraulic cylinder. It forms a closed chamber with the cylinder head, piston, and other components to drive the movement of the piston.

CYLINDER HEAD

The cylinder head is installed at both ends of the hydraulic cylinder and forms a tightly sealed oil chamber with the cylinder barrel.

PISTON ROD

During the operation of the cylinder, the piston rod is subjected to thrust, tensile force, or bending moment. The surface roughness, straightness, and roundness of the piston rod should be appropriate as it often slides within the guide sleeve.

PISTON

The piston is the main component that converts hydraulic energy into mechanical energy. Its effective working area directly affects the actuating force and movement speed of the hydraulic cylinder.

GUIDE SLEEVE

The guide sleeve guides and supports the piston rod. The guide sleeve is equipped with a sealing device to ensure the sealing between the cylinder barrel and the rod chamber. It is also equipped with a dust seal on the outer side to prevent impurities, dust, and moisture from entering the sealing device and damaging the seal.

CUSHIONING DEVICE

When the piston and piston rod move under the driving force of hydraulic pressure, they have a significant momentum. When they enter the end cap and the bottom of the cylinder, they can cause mechanical collision, resulting in high impact pressure and noise.
The cushioning device is used to prevent such collisions. Its working principle is to throttle the oil in the low-pressure chamber of the cylinder barrel (completely or partially), converting kinetic energy into thermal energy, which is then carried away from the hydraulic cylinder by the circulating oil.

The main parameters of a hydraulic cylinder include pressure, flow rate, size specifications, and piston stroke.

1. PRESSURE:

Pressure refers to the pressure of the oil on a unit area. The calculation formula is p = F/A, which is the load on the piston divided by the effective working area of the piston.
From the above formula, it can be seen that the establishment of pressure value is caused by the presence of the load, and the load determines the pressure.

2. FLOW RATE:

It refers to the amount of oil passing through the effective cross-sectional area of the cylinder barrel per unit time.

3. PISTON STROKE:

The piston stroke refers to the distance between the two extremes when the piston reciprocates. Generally, after satisfying the stability requirements of the cylinder, a standard stroke is chosen that is close to the actual working stroke.
