2025-01-20

Firstly, try to use sealant as much as possible, and if necessary, use paint as a substitute to achieve the desired sealing effect;

Secondly, the appearance quality of the rubber seal device should be carefully inspected before installation; Use specialized tools to press fit and avoid deformation caused by knocking;

Thirdly, add lubricating grease according to the rules, clean and clear the ventilation holes and one-way valves regularly.

Fourthly, the device should be installed under extremely clean conditions, with no bumps, scratches, burrs, or other attachments on the working surface of the parts;

Fifth, strict operating procedures should be followed, and sealing components should be installed correctly to avoid deformation if not in place;

Sixth, grasp the functional standards and application requirements of sealing components, and promptly replace faulty components;

Seventh, for thin-walled parts such as edge covers, use sheet metal cold work for calibration; Simple wear and tear of shaft hole parts can be achieved through processes such as metal spraying, welding repair, adhesive bonding, and mechanical processing to reach the original factory scale;

Eighth, if the nut slips or becomes loose, it should be corrected or replaced with a new part, and tightened to a regular torque.
