The hydraulic cylinder is composed of 5 parts:
Cylinder barrel and cylinder head, piston and piston rod, sealing device, buffer device, and exhaust device. It is the most important executive force element in the hydraulic system, converting hydraulic energy into mechanical energy. When one of the oil holes is filled with oil, the piston is pushed to make the other oil hole flow out, realizing the piston rod.
The principle of back-and-forth. The front flange type hydraulic cylinder, which fixes the cylinder flange and the plate frame, can realize the action of pressing the cylinder from top to bottom. Mainly used in construction machinery and equipment, such as presses, balers, shaping machines, etc.
