Hydraulic cylinders are key power - actuating elements that efficiently convert hydraulic energy into mechanical energy and are widely used in numerous industrial fields.
Structurally, they mainly consist of a cylinder barrel, piston rod, piston, cylinder head, and seals. The cylinder barrel, as the core - bearing component, is finely machined to provide a stable moving space for the piston. Its excellent inner - surface quality ensures the smoothness and tightness of the piston's movement. The piston rod, which is the crucial link for force transmission, connects the piston and the external load. High - quality materials and high - precision processing techniques make it highly strong and wear - resistant, enabling it to withstand huge axial forces. The piston is precisely installed inside the cylinder barrel, and its appropriately sized effective working area can generate powerful thrusts based on the pressure of the hydraulic oil to drive the piston rod to complete linear reciprocating motion. The cylinder heads are firmly installed at both ends of the cylinder barrel and, together with the cylinder barrel, form a sealed oil chamber, which not only ensures the stable fixation of the internal components but also guarantees the tightness of the entire hydraulic system. The seals, like loyal guards, with various types such as O - rings and U - rings, have excellent sealing performance to prevent hydraulic oil leakage and the intrusion of external impurities, forming an important line of defense for maintaining the stable operation of the hydraulic cylinder.
