Measures to reduce the leakage of the piston rod seal
Sep 28, 2018

In actual work, during the use of the piston rod, the leakage may be caused by factors such as damage. In response to such problems, we can choose the inner and outer double lip dust seals to prevent dirt from entering the hydraulic cylinder from the lip and the bottom of the groove. Moreover, a protective plate is added to the piston rod earring to effectively reduce and avoid the hidden danger of the bump.


Secondly, in the process of manufacturing and manufacturing the piston rod, the process level should be further improved. For example, the surface medium frequency quenching is adopted, and the hardness of the substrate is improved by medium frequency quenching, which can increase the surface anti-collision ability and reduce the surface roughness value of the rod. In addition, the plug rod forms a cylindrical structure, which can improve the bending strength of the piston rod.


In addition, when the structural design is carried out, the matching clearance between the piston rod and the guide sleeve can be appropriately designed and selected. At the same time, it is necessary to ensure the lubrication of the lip of the sealing ring to avoid abnormal high temperature due to friction. Meeting these requirements will be able to reduce the leakage of the piston rod seal.http://www.xhychromerod.com/
