Seals are the core vulnerable parts of SC cylinders, and their selection, matching, and maintenance quality directly determine the cylinder life. When selecting, it is necessary to match the appropriate materials according to the working conditions: nitrile rubber seals are selected for normal temperature working conditions, fluororubber materials are used for high temperature working conditions, and polytetrafluoroethylene seals are selected for corrosive environments to avoid rapid aging caused by material mismatch. It is recommended to prioritize the use of original seals, which have a fitting accuracy of up to 99% with the cylinder body. Non original parts can easily cause leaks and scratches on the cylinder body.
In daily maintenance, check the seals for deformation and cracks every week, and clean the sealing surface with a special cleaning agent every month to avoid oil accumulation and affect the sealing effect. Non oil lubricated cylinders require special lubricating grease to be added to the seals every 6 months to form a protective film and reduce friction losses. When repairing or replacing, it is necessary to first empty the pressure inside the cylinder. When disassembling the tension rod bolts, follow the diagonal sequence to avoid deformation of the cylinder body; Before installing the new seal, ensure that there are no impurities in the sealing groove, apply a thin layer of lubricating grease to assist in installation, and prevent scratching the sealing surface during installation.
