What is a single-acting hydraulic cylinder piston rod is only one end of the call into the single-acting hydraulic cylinders, engineering mechanical rod basically single out, rod mill on the machine, such as flat-out classes are single, cylindrical grinding The cylinder is double out. Very simple, look at the cylinder port, there is a single action on the large tonnage cylinders, two double-acting is meant: hydraulic pressure piston or plunger only a single direction of motion, reverse the direction of movement must be realized by external forces, force: the spring force or weight. Cylinder machining cylinder as the main components of the price of the fuel tank cylinder, single pillar mining, hydraulic support, barrel and other products, and its processing quality directly affects the entire product life and reliability. Cylinder high processing requirements, the inner surface roughness is Ra0.4 ~ 0.8μm, concentricity, wear resistance 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 a closed surface microcracks, impede erosion expansion. Thereby enhancing the corrosion resistance of the surface, and can delay fatigue cracks or expansion tank, 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. Cylinder Cylinder manufacturers _ _ Lu Lu Hydraulic power is provided by a hydraulic machinery plant in Texas.
