The precision piston rods we choose generally have the effect of plastic deformation. In order to achieve better sealing of the piston, experiments will be conducted with different materials to improve the deformation and elastic effect of the materials. The design contact surface of the cylinder barrel is also improved through the design effect of the cylinder rod surface, which can have better elasticity and wear resistance. This design feature naturally aims to have a better degree of coordination, increase the corresponding matching properties, and ensure the effectiveness of operation.
Through the design effect of this contact surface, the deformation of the precision piston rod cylinder barrel caused by mutual contact can also be avoided, after all, the piston effect that needs to be achieved through this type of sealing effect. Be careful to avoid burns caused by grinding accidents. This operation requires attention to elastic protection, so that the cylinder barrel used in the later stage can still have a reliable processing effect. After the rolling process, attention should also be paid to the elastic effect of the contact surface. The better the coordination and design, the more elastic the effect can be achieved by reducing surface roughness.
We can all learn from this design precaution and also improve the fitting properties of precision piston rod cylinder barrel. In the later application practice process, if such materials and processing methods are used as a whole, the service life of the piston rod can also be increased at the same time. After all, this is a high-quality process that can greatly reduce the damage caused by the movement of the oil cylinder rod piston, and the loss of such products provides protection. This operation and protection both serve to seal and preserve the sealing ring, resulting in a good protective effect.
