Hydraulic cylinders are hydraulic energy into mechanical energy, make a linear reciprocating motion (or swing movement) of the hydraulic actuators. Simple structure, reliable work. When to use it to achieve reciprocating cylinder, can be removed from deceleration devices, and does not drive the price gap between the cylinder, smooth motion, so widely used in various mechanical hydraulic system. Hydraulic cylinder output force and the effective area of ??the piston and the pressure is proportional to both sides; consisting essentially of hydraulic cylinders and cylinder head, piston and piston rod, seals, cushioning device component and exhaust. Cushioning device and the exhaust depending on the specific application may be, the other devices are essential machining cylinder cylinder cylinder as the main component, single pillar mining, hydraulic support, barrel and other products, and its processing quality is good or bad directly affects the life and reliability of the product. Cylinder machining requirements, the inner surface roughness of cylinders Ra0.4 ~ 0.8μm quality of concentricity, wear demanding. The basic characteristics of the cylinder is the deep processing, the processing has been plagued by processing staff. Using rolling processing, leaving the surface because the surface layer of residual compressive stress, helps surface microcracks closed large tonnage cylinders, impede erosion expansion. Thereby enhancing the corrosion resistance of the surface, and can delay fatigue cracks or expanded, thus increasing the fatigue strength of the cylinder. By roll forming, cold rolling the surface layer of the hardened layer, the elastic and plastic deformation to reduce the grinding surface of the auxiliary contact, thereby improving the wear resistance of the inner wall of the cylinder, while avoiding burns caused by grinding. After rolling, the reduction of the surface roughness can be improved with the nature. The quality of the fuel tank, fuel tanks, hydraulic force provided by the Texas Lu Lu force hydraulic machinery plant. Texas Lu force hydraulic machinery plant (www.luliyeya.com) strong, credible, in Dezhou hydraulic machinery and components industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Lu Hydraulic and you hand into the brilliant, for a better future!
