The structure of the hydraulic cylinder
The hydraulic cylinder is usually composed of the main parts of the back end cover, cylinder barrel, piston rod, piston assembly, front end cover, etc.; in order to prevent oil leakage to the hydraulic cylinder or leakage from the high pressure cavity to the low pressure cavity, the cylinder and the end cover, piston Sealing devices are installed between the piston rod, the piston and the cylinder, the piston rod and the front end cover. On the outside of the front end cover, there is also a dustproof device; in order to prevent the piston from hitting the cylinder head when it quickly retracts to the stroke end, the hydraulic cylinder end The department is also equipped with a buffer device; sometimes an exhaust device is required
The figure above shows the structure of a double-acting single-piston rod hydraulic cylinder. The hydraulic cylinder is mainly composed of cylinder bottom 1, cylinder tube 6, cylinder head 10, piston 4, piston rod 7 and guide sleeve 8 ; one end of the cylinder is connected to The bottom of the cylinder is welded, and the other end is screwed to the cylinder head. The piston and the piston rod are connected by a snap key. In order to ensure the reliable sealing of the hydraulic cylinder, sealing rings 3, 5, 9, 11 and dustproof rings are set at the corresponding positions
