4. Remove Old Seals Once you can access the seals, carefully remove the old seals using appropriate tools. Avoid scratching or damaging the surfaces where the new seals will be placed.

1. Prevention of Fluid Leakage The primary function of the oil seal is to prevent fluid leakage, which can result in inadequate lubrication and increased wear on moving parts.

One is to do a good job of galvanized wire packaging, avoid bump, to ensure the integrity of the zinc layer;

Domestic iron wire factory has been able to consume wire rope, radial low steel wire, umbrella steel wire, spring steel wire, bicycle saddle spring steel wire and other products. In the 1980s, hot – plated low carbon steel wire, fan net cover steel wire, carbon structure steel wire, bed steel wire and so on were also published. The elongation of wire is increased after annealing. Make the product more soft and increase the scope of application of the wire.

Hot dip galvanizing is then oiled and chromed. The quality of hot-galvanized sheet produced by this method is significantly improved compared with that by wet galvanizing method. It is only valuable for small-scale production. Continuous galvanizing production line includes a series of pretreatment procedures, such as alkali degreasing, hydrochloric acid pickling, water washing, solvent coating, drying, etc., and the original plate needs to be annealed in cover furnace before entering the galvanizing line.
