Hydraulic cylinder, which is a kind of pressure finishing, is the use of metal at room temperature state cold-plastic characteristics, the use of rolling things on the surface of the workpiece to exert a certain pressure, so that the metal attack on the surfaces of the workpiece plastic activity, filled into the original residue of the Thellos trough, and reached the surface roughness of the workpiece reduced. Due to the plastic deformation of the surface metal, the surface tissue cold hardening and fine grains, forming a dense fibrous shape, and constitute the residual stress layer, hardness and strength progress, and then improve the appearance of the workpiece wear resistance, corrosion resistance and cooperation.
How can hydraulic cylinders be serviced to prolong their useful life? The hydraulic cylinder is the linear moving performance element of the output force. Its function is to convert hydraulic energy into mechanical energy. The input amount of the hydraulic cylinder is the flow and pressure of the fluid, and the output is the speed and force of the linear motion.
The hydraulic cylinder is basically composed of cylinder and cylinder head, piston and piston rod, sealing equipment and other parts.
As the hydraulic cylinder to accept a large pressure, the heavier the load, it will be more pressure, therefore, do a good job of the maintenance of hydraulic cylinder is the most important part of the maintenance of the hydraulic system. Hydraulic cylinder is equivalent to the heart of the hydraulic system, heart problems are difficult to repair, so the maintenance of hydraulic cylinder is to be careful and detailed.
