        Luxembourg plating press hydraulic cylinder

        (Luxembourg plating press hydraulic cylinder,produced by Hengyu Group)

        plating press hydraulic cylinder are widely used in Luxembourg,because of no transmission clearance,powerful torque,clever hydraulic energy conversion.So our company has designed plating press hydraulic cylinder for customers from Luxembourg.

        Introduction to plating press hydraulic cylinder:

        Analysis of commonly used seals: The wear ring and slip ring commonly used on the plating press hydraulic cylinder are generally made of polytetrafluoroethylene + graphite, because pure polytetrafluoroethylene is easy to produce plastic creep, which is only suitable for low pressure and low wear resistance conditions. If the sealing ring used is a composite material formed after adding graphite filler, the performance can be effectively improved, the ability to resist plastic creep is increased by 2 to 3 times, the initial deformation caused by the load is reduced by 30 to 60% : the rigidity is increased by 2 to 3 times: the dimensional stability under heat is increased by 2 times, and the hardness is increased by l0 to 15%.

        The internal leakage of the plating press hydraulic cylinder should be prevented when the plating press hydraulic cylinder is used. The internal leakage of plating press hydraulic cylinder includes the leakage caused by excessive wear of plating press hydraulic cylinder block seal, piston rod and seal cover seal and piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time.

        How the cavitation of the plating press hydraulic cylinder is formed: With the gradual rise of pressure, the gas in the oil will become bubbles, when the pressure rises to a certain limit value, these bubbles will break under the action of high pressure, so that the high temperature and high pressure gas will quickly act on the surface of the parts, resulting in cavitation of the plating press hydraulic cylinder, resulting in corrosive damage to the parts.

        In recent years, the processing process of the plating press hydraulic cylinder generally adopts the rolling method, which is a pressure finishing processing, which uses the cold plastic characteristics of the metal at room temperature, and uses the rolling tool to exert a certain pressure on the surface of the workpiece, so that the surface metal of the workpiece produces plastic flow, and fills in the low concave trough of the original residue, and the roughness value of the workpiece surface is reduced. Due to the plastic deformation of the rolled surface metal, the surface tissue is cold hardened and the grain is fine, forming a dense fiber, and forming a residual stress layer, and the hardness and strength are increased, thus improving the wear resistance, corrosion resistance and compatibility of the workpiece surface. Rolling is a plastic machining method without cutting.

        Answers to some questions about plating press hydraulic cylinder:

        How to judge the leakage in the cylinder?
        Common judgment method: In the production site, people make full use of watching, listening, smelling, touching and other sensory ways, by observing that the cylinder can not move or delay the action or feel the oil temperature change, vibration and noise, etc., and then judge whether the cylinder has internal leakage according to experience. Another method commonly used in the field is to extend the cylinder in place to ensure that the cylinder does not have any load and will not retract (to prevent the cylinder from internal leakage accidents), turn off the machine, and then remove the tubing with the rod cavity, and then press the switch that pulls out the cylinder (do not press the wrong switch). If the oil nozzle with the rod cavity drains the cylinder internally, If there's no oil coming out, you have to think about something else going wrong.

        What causes hydraulic cylinder oil leakage?
        1. Internal leakage (1) The wear ring on the piston is seriously worn, leading to friction between the piston and the cylinder liner, and finally strain the cylinder liner, piston and seal; 2) Seal long-term use failure, piston seal (mostly U, V, Y ring, etc.) aging; 3) The hydraulic oil is dirty, and a large number of impurities enter the cylinder and wear the piston seal to bad; 2. External leakage 1) cylinder inlet and outlet tubing joint cracking; (This I see in the actual work is still more) 2) The piston rod extension end with the piston rod seal damage, mostly due to the piston cylinder is caused by hair, but also caused by aging; 3) The seal between the extended end of the piston rod and the liner is damaged.
