Multifunctional surface hydraulic hydraulic device is not sharp minor edge, prolonged friction movement will not damage seals or seals, which is especially important in the hydraulic industry. Rolling principle it is a pressure finishing, is characterized by the use of metal cold plastic state at room temperature, the use of rolling tool to exert pressure on the surface of the workpiece surface metal plastic flow, fill to the original residual in low-lying valleys, and reach the surface roughness value decreased due to be rolled plastic deformation of the surface of the metal, so cold hardening and grain tapering surface tissue, forming a dense fibrous. and the formation of residual stress layer hydraulic cylinders, hardness and strength increase, thereby improving the wear resistance, corrosion resistance and the mating surface of the workpiece. Rolling is a non-cutting plastic working method. More technology consulting: no machining technology safe, convenient and precise control precision, several major advantages: 1. Correction roundness, ovality can ≤0.01mm. 2. Improve the surface hardness 1500T hydraulic cylinders, so that by eliminating deformation, hardness HV≥4 ° 3. After machining residual stress layer, improve the fatigue strength increased by 30%. 4. Improve with the quality and reduce wear and extend the life of parts, but the parts but lower processing costs. Solve the problem of hydraulic cylinder piston stuck hydraulic cylinder piston stuck generally refers piston stuck in the cylinder bore, resulting in the pump stops, the best result in problems with the hydraulic system, the machine can not normal work. The main reason for non-normal piston stuck deformation of the cylinder bore. When the pump is usually due to co-mounted, center the ball fall, a pump will start rolling cylinder end face card leaving the cylinder bore distortion killed plunger; in addition, the center spring break, cylinder bearing roller bearing cage damage inside, the card will be rolling the plunger pump rotating member killed or damaged pump. Typically encounter this problem, the first thought is the important parts, such as hydraulic cylinders are removed one by one check, but often because of damaged parts too severe, the possibility of repair is unlikely, are needed to replace the new 1000T hydraulic cylinders, although this is more rapid and effective, but more expensive because of the price of new parts, if not necessary, then this method is not desirable, the cost is too high. As long as the deformation of the cylinder is not so serious, we can film, so that it remains in the shape, position within the permissible error range, then put on the outside diameter of the corresponding cylinder plunger right, so use it with the new-for-parts basically the same effect.
